Apple has seemingly had one of its most useful AI tools blocked from Meta's apps. Writing Tools, which is an Apple Intelligence feature, is not available to use in Facebook, WhatsApp, Instagram, Threads, and Messenger.

Apple's Writing Tools include options to proofread, rewrite, and summarize text almost anywhere you can type in iOS 18. A long press in a text input field usually brings up the feature, but not in any of Meta's apps currently.

Brazilian blog Sorcererhat Tech spotted the lack of Writing Tools across Meta's apps, which appears to have been the case since late last year. Developers can choose whether to allow the tools in their apps, so it looks as if Meta has declined the offer.

According to a Wall Street Journal report from June 2024, Apple held discussions with Meta about integrating the Facebook owner's AI model into iOS 18 as part of its Apple Intelligence feature set. However, Apple turned down the AI partnership due to privacy concerns. Apple instead ended up signing a deal with OpenAI to include optional ChatGPT access in its Siri responses.

Given the history of acrimony between the two companies – from Apple device interoperability demands to App Store feuds – it's not all that surprising that Meta would choose to keep Apple's AI out of its apps. Meta has also since rolled out its own AI features across its platforms.

xAI has rolled out a new memory feature for Grok, its conversational AI, making the chatbot smarter and more personalized over time. With memory enabled, Grok can now recall past interactions – like your preferences or previous questions – to provide more relevant recommendations and responses.

According to xAI, this feature brings Grok in line with memory capabilities already found in platforms like ChatGPT and Gemini, where chat history can be revisited and used to enhance future conversations. Users can now rely on Grok to pick up where they left off, improving long-term usability.

The memory feature is currently available in beta on the Grok website and through its iOS and Android apps. However, users in the EU and UK will have to wait, as the feature isn't yet supported in those regions. xAI says it plans to integrate memory into Grok's built-in version on X (formerly Twitter) "soon."

Just like with other memory-enabled AI tools, users have the ability to manage what Grok remembers, although telling Grok to "Forget" referenced chats won't delete them from the user's history.

Apple's iPhone 18 models will adopt TSMC's 2nm manufacturing process for the next-generation A20 chip, which will bring substantial performance and power efficiency improvements to next year's iPhones, but it may also incur significantly more costs that Apple could pass onto the customer.

The latest corroboration that Apple will use TSMC's 2nm process in next year's iPhone models comes from Weibo-based leaker Digital Chat Station, who has sources in the Chinese supply chain. Industry analysts Ming-Chi Kuo and Jeff Pu have previously claimed as much, so it seems all but confirmed that Apple will adopt the more advanced silicon wafer technology.

In 2023, Apple adopted 3nm chips for its iPhones and Macs, an upgrade over the prior 5nm mode. The switch to 3nm technology brought 20 percent faster GPU speeds, 10 percent faster CPU speed, and a 2x faster Neural Engine to the iPhone, and similar improvements on Macs. The upcoming iPhone 17 series is expected to feature processors made using TSMC's N3P chip technology – an enhanced version of the 3nm process – but 2nm adoption in the iPhone 18 is expected to bring significantly more performance and efficiency gains.

The terms "3nm" and "2nm" describe generations of chip manufacturing technology, each with its own set of design rules and architecture. As these numbers decrease, they generally indicate smaller transistor sizes. Smaller transistors allow more to be packed onto a single chip, typically resulting in increased processing speed and improved power efficiency.

TSMC plans to start manufacturing 2nm chips in late 2025, and Apple is expected to be the first company to receive chips built on the new process. TSMC is building two new facilities to accommodate 2nm chip production, and working on approval for a third. TSMC generally builds new fabs when it needs to increase production capacity to handle significant orders for chips, and TSMC is expanding in a major way for 2nm technology.

However, with Apple expected to be the first major beneficiary of the new process, it is also likely to face significantly increased costs, which could see the iPhone 18 face another round of price hikes on top of possible price increases on this year's iPhone 17 models due to U.S. import tariffs. Apple scored a reprieve from the 145 percent tariff impacting goods imported from China and the 10 percent tariff on goods imported from other countries, but it doesn't sound like that's going to last.

U.S. President Donald Trump is currently working on new semiconductor levies that will likely impact all Apple devices. Trump earlier this week said that no one is "getting off the hook" and there "was no tariff exception." Apple and other tech companies are "just moving to a different tariff bucket," with the 20 percent "Fentanyl Tariffs" still in place, and additional tariffs coming.

Apple has quite a few security features that it's added to iPhones, iPads, and Macs over the years. Now more than ever, it's important to make sure you're taking advantage of the built-in security tools that are available to keep yourself and your data safe, so we've rounded up a list of the most important options.

If you don't already have these enabled, you might want to consider turning some of them on.

Two-Factor Authentication

With two-factor authentication, you need to verify your identify when you sign into iCloud on a new device or on the web. It works by sending a six-digit code to a device where you're already signed in, and it won't authorize a sign-in on the new device unless you input that code from your existing device.

If you have an iPhone and want to sign into your ‌iCloud‌ account on your Mac, for example, when you enter your Apple Account name and password, you'll get a pop-up on your ‌iPhone‌ with a code that you input for identity verification. Alternatively, you can set a trusted phone number where you can also get a code in case you forget your password.

Apple tries really hard to get people to use two-factor authentication, so chances are you have it enabled, but if you don't, it's a first line of defense to protect your data. There are even some iOS features that don't work without it.

You can manage two-factor authentication by going to Settings > Sign-In and Security.

Security Keys

For an extra layer of protection with two-factor authentication, you can add physical security keys, such as the YubiKey. With a security key set up, you verify your identity with a physical dongle via USB-C or NFC.

Security keys make sure no one can break into your account even if they have access to one of your trusted devices, but you definitely don't want to lose a security key. You can set this up in the two-factor authentication section of the Settings app.

Stolen Device Protection

Stolen Device Protection is a feature that Apple added after criminals got clever and started watching people enter their passcodes before stealing an ‌iPhone‌.

When you turn on Stolen Device Protection, a passcode won't work for accessing sensitive information like passwords and credit card data. Instead, Face ID or Touch ID biometric authentication is required, so if a thief has your ‌iPhone‌ and your passcode, they won't be able to get into your accounts.

There's also a security delay that keeps your Apple Account password from being changed without two instances of biometric authentication and an hour-long delay.

Thieves are blocked from accessing passwords, making purchases, turning off Lost Mode on an ‌iPhone‌, applying for an Apple Card, using an ‌iPhone‌ to set up a new device, and accessing credit cards and Apple Cash. There are delays for signing out of an Apple Account, changing a password, resetting settings, and turning off Stolen Device Protection.

By default, Stolen Device Protection is only on when you're away from familiar locations like your home or your work, but if you want it on at all times, you just need to change the toggle to Always.

You can get to the Stolen Device Protection settings by opening up the Settings app, going to the ‌Face ID‌ and Passcode section, and tapping on Stolen Device Protection.

Private Relay

Private Relay is more of a privacy feature than a security feature, but it's something that you should have on. It hides your IP address and browsing activity in Safari and protects unencrypted internet traffic so no one can see what you're doing even if you're on an unsecured network.

Private Relay is an ‌iCloud‌+ feature that you get access to as long as you pay Apple at least $0.99 a month for 50GB of ‌iCloud‌ Storage, and it's well worth it. You should also take advantage of Hide My Email whenever possible, as it will give you temporary email addresses that you can revoke at any time.

Private Relay can be enabled by opening up Settings, tapping on your profile picture, and tapping on the ‌iCloud‌ section.

Advanced Data Protection

By default, some of the data that's saved in ‌iCloud‌ backups and uploaded to ‌iCloud‌ is not end-to-end encrypted, which means that Apple can provide ‌iCloud‌ backup data to law enforcement.

Advanced Data Protection encrypts your ‌iCloud‌ data so that it cannot be decrypted except for on your personal devices signed into your Apple Account. It is Apple's highest security option for cloud data.

The feature protects device backups, Messages backups, iCloud Drive files, Notes, Photos, Reminders, Safari bookmarks, Siri Shortcuts, Voice Memos, and Wallet Passes, all of which can otherwise be accessed in ‌iCloud‌ backups by subpoena.

Advanced Data Protection is a good idea to turn on, but keep in mind that it means even Apple can't recover your data if a password is lost. To use Advanced Data Protection, Apple requires you to have a recovery key saved or a recovery contact set up as a way to regain access to your account should you lose your password.

You can get to Advanced Data Protection by opening up the Settings app, tapping on your profile picture, selecting ‌iCloud‌, and then scrolling down to the Advanced Data Protection section. You can also turn it on in the Privacy and Security section of the Settings app.

Lockdown Mode

Lockdown Mode is an extreme security option that most people won't want to turn on, but it's good to know where it is in case you need it.

Apple designed this feature for journalists, activists, government employees, and others who might be in danger of being subject to sophisticated cyber attacks and mercenary spyware.

Lockdown Mode disables a lot of ‌iPhone‌ features, blocking Message attachments, web technologies like JIT (just-in-time JavaScript compilation), FaceTime calls from unknown contacts, shared albums in the ‌Photos‌ app, invites for Apple services from unknown people, physical device connections, and configuration profiles.

It essentially removes common attack vectors by limiting ‌iPhone‌ functionality, so it's not something you're going to want to use day-to-day unless you need it. Lockdown Mode can be turned on by opening up Settings, going to Privacy and Security, and tapping on the Lockdown Mode option.

Contact Key Verification

Similar to Lockdown Mode, Contact Key Verification is designed for a limited number of people who need to confirm the identify of who they are speaking to. It provides an option to compare contact verification codes with someone in person or over the phone, so no one can impersonate that person at a later date.

Apple today started sending out emails to Apple Card users, letting them know about a new Booking.com promotion. From now through May 15, ‌Apple Card‌ users can get five percent total Daily Cash back when using ‌Apple Card‌ with Apple Pay.

Booking.com is a site that allows users to reserve flights, hotel stays, car rentals, cruises, and more.

‌Apple Card‌ owners can get up to $500 Daily Cash back on eligible hotel stays and car rentals using the ‌Apple Card‌ Booking.com link.

Booking.com is also providing two percent in Booking.com Travel Credits on eligible stays and car rentals that are booked through the ‌Apple Card‌, which is on top of the 5 percent Daily Cash back.

Right now, Apple is also offering an ‌Apple Card‌ promotion for referrals, offering anyone who is referred to ‌Apple Card‌ a $75 Daily Cash bonus. The invitee will need to open a new ‌Apple Card‌ and make a purchase within 30 days of opening the account.

In its 2025 Environmental Progress Report released today, Apple revealed that it plans to expand its Clean Energy Charging feature to iPhone and iPad demo units on display at Apple Stores and other retail stores across the United States.

Introduced in the United States in 2022, as part of iOS 16.1, the optional Clean Energy Charging feature enables iPhone users to charge their devices at times of the day when the electric grid is relatively cleaner. Apple says the feature can reduce your carbon footprint by selectively charging when lower carbon-emission electricity is available.

In a new document, obtained by MacRumors contributor Aaron Perris, Apple said the Clean Energy Charging feature will be enabled by default on all iPhone and iPad demo units in U.S. stores, reducing the carbon footprint of those devices. To ensure that the demo units are always ready to be used by customers, Apple said devices will resume charging immediately in the event that they drop below 50% battery life.

Clean Energy Charging is enabled by default for customers too. On iOS 16.1 and later, the feature can be managed in the Settings app, under Battery → Battery Health & Charging. The feature is still available in the contiguous United States only.

It is unclear exactly when the feature will be enabled on iPhone and iPad demo units.

This is just one of several environmental initiatives and milestones that Apple has announced ahead of Earth Day on April 22.

Apple has a support document with more details about Clean Energy Charging.

With iOS 18.4, Apple added support for robot vacuums to HomeKit. There are a few Matter-enabled robot vacuums that can be added to the Home app for use with Siri, including the Deebot X8 Pro Omni from Ecovacs. I've been testing the X8 Pro Omni for the last several weeks to see if it's worth upgrading to a robot vacuum with Matter support to integrate with ‌Siri‌ and ‌HomeKit‌, as well as to check out its cleaning capabilities.

Design

The X8 Pro Omni is a circular vacuum that can both vacuum and mop, so it is an all-in-one floor cleaning bot. It comes with a base that has a dust bag, section for cleaning fluid, a tank for clean water, and a tank for dirty water.

This is not a small robot vacuum, and it's not going to be ideal for small spaces. It's almost 14 inches wide and about four inches tall. I have a TV stand that's four inches high and the vacuum does not fit underneath it, but it is short enough to get under most furniture, including my couch, bookcases, bed, and desks. Because of the width, it cannot get into spaces that are tight, such as a chair close to a table leg, or two chairs that are close to one another.

The base station is 21 inches tall, 14 inches wide, and 11 and a half inches deep, and you need to have enough area around it for the robot to dock itself. The X8 Pro Omni is black and gold, as is the station, but it's not garish. It blends right in, and even though the charging station is large, I was able to tuck it away in a corner.

There is a built-in camera at the front of the X8 Pro Omni, which is used for navigation, room mapping, and obstacle avoidance, plus it has a microphone for listening for voice commands and a speaker to respond and to ask for help if it gets stuck.

Cleaning

I've always been skeptical of robot vacuums, but I was impressed with the X8 Pro Omni. It has serious suction power (Ecovacs says 18,000 Pa) that was able to clean up cat hair and everything else on my floors, and running it regularly kept my floors a lot cleaner than my typical weekly vacuuming. The suction power is adjustable, and higher suction is noisier, but I mostly used it in the higher mode to get everything off of my floors.

I'm able to work in the room with the X8 Pro Omni running even at its highest suction, but I probably wouldn't take a phone call. It's the loudest when vacuuming, and is usually between 50 and 60 decibels with the standard mode. The mopping is quieter, and emptying the dust is the loudest operation.

There's a little spinning brush on the side that's meant to get around the edges of a room, and in the weeks that I've been using the vacuum, it's done a good job getting into nooks and crannies. There's also a mopping feature, and the mop that Ecovacs included is something special. It's a roller mop rather than the spinning mop that other robot vacuums have, and I think it cleans stains like dried cat food better than my other vacuum that has spinning mops.

With two passes, it was able to get most of the little bits of dried food off of my floor. I even tested it with dried ketchup that I put on the floor, and while it didn't get everything off in one go, it got close. The idea with robot vacuums is to have them clean daily or several times a week, and the X8 Pro Omni was able to keep my floor spotless with a schedule.

The Ozmo Roller, as Ecovacs calls it, is cleaned off with a water nozzle as the vacuum mops the floor, so dirty water is scraped off and clean water is reapplied. I like that concept better than a robot vacuum dragging dirty water along the floor, and it did seem to be effective. I don't wear shoes in the house and my floors are relatively clean, but the waste water was always dirty, so grime was coming up with every cycle. The X8 Pro Omni can clean the floor with just water, but it does accept cleaning solution that you can put in the base to fill the vacuum. Ecovacs recommends using its own cleaning solution to avoid damaging the vacuum.

I have wood floors, and I am careful with them. The X8 Pro Omni has not done any damage, but I do check the wheels and the mop to make sure nothing gets lodged there. The wheels are rubber and the mop is soft, so it doesn't seem like there's anything that would cause an issue.

I don't want to go on forever about the cleaning capabilities of the robot, so I'll wrap up by saying it did a great job, but there are a few caveats with navigation and obstacle avoidance.

The X8 Pro Omni needs to be able to get to the floor, and it will have a hard time in rooms with a lot of furniture or items on the floor. I have to do a pass before I have it clean to move cat toys and whatever else I might have on the floor. While cleaning, the robot will empty its dust bin on its own, wash its mop, and recharge, so you just hit the start button and it goes about its chore on its own.

It does require my attention with rugs, because it can't handle them. I have some thin area rugs that I don't have any kind of rubber padding under, and the X8 Pro Omni cannot deal with these. It routinely sucks up the tassels on one of my rugs and gets itself tangled up, and getting up to fix it every two minutes when it's doing that section of the room is frustrating.

It does better with the thicker rugs I have in the bathroom that do have a sturdier backing, and it can navigate and vacuum those with fewer issues. I have one large area rug that isn't a problem, and it does fine, but that is the extent of the carpet in my house so I haven't been able to test carpet suction beyond my rugs.

For context, it takes two hours for it to deep clean a 600 sq ft room, of which it can access about 400 sq ft (because of furniture). A standard clean is closer to an hour. I've locked it in my office for this review, but were it to clean my whole house, it would take several hours and would likely need to recharge. The two hour deep clean does not require recharging, and leaves it with about 30 percent battery at the end. When used in standard mode, the X8 Pro Omni can run for over 3.5 hours before needing to charge. For a full recharge, it takes approximately four hours.

Upkeep and Performance

There are filters that need to be changed, water that needs to be added and emptied, and components that eventually need to be replaced. The Ecovacs app has a detailed Maintenance section that lets you know when you need to perform maintenance. A filter lasts for 120 hours, and the mop works for 150 hours. In the month that I've been testing the X8 Pro Omni, I haven't had to do anything other than add more water to the clean water bin.

There is some cost associated with upkeep, as components will need to be replaced over time. A new roller mop, for example, is $30, and three dust bags is $25.

I have not run into issues while testing the X8 Pro Omni. The robot is responsive, it has not gone offline, and the app has been stable. I also haven't had hardware issues, and Ecovacs does have a standard one-year warranty.

HomeKit and Siri

iOS 18.4 and its sister updates add support for Matter-enabled robot vacuums, so to be able to control the X8 Pro Omni from the Home app and via ‌Siri‌, iOS 18.4 or later is required.

Functionality is limited, compared with the feature set that is available with the Ecovacs website. In the Home app, there's a button to start the robot and to choose whether the robot vacuums or mops. Specific rooms that have been set up with the Ecovacs app can be selected, or you can choose to have the X8 Pro Omni clean all rooms that it has access to.

There's also a built-in toggle for Quick or Deep Clean, which controls the cleaning pattern that the robot uses. ‌Siri‌ commands can be used in lieu of the Home app, so you can say something like "turn on the Deebot" to start a cleaning cycle (I named the robot Deebot in the Home app).

Commands like "tell Deebot to vacuum" or "tell Deebot to quick clean" didn't work with ‌Siri‌, because ‌Siri‌ just kept telling me there was no Deebot in my contacts list. It was a frustrating experience trying to use ‌Siri‌ to activate and control the vacuum, and using the Ecovacs app or the Home app was simpler.

It's not Ecovacs' fault that ‌Siri‌ is less than capable, and the Ecovacs app is an easier solution for the most part, though I was also perfectly able to control the vacuum from the Home app.

Ecovacs App and Mapping

The Ecovacs app has a much deeper feature set than is available with the Home app or with ‌Siri‌, including its own personal assistant that can respond to voice-based commands.

Operating the X8 Pro Omni requires the Ecovacs app for setup and for specialized controls. Setup was a super simple process, and the app is complicated, but easy enough to figure out. There's an overarching "Home" that houses all of your Ecovacs products, and tapping into one brings up controls. You can start or pause the robot from this interface, or send it to recharge, and additional options are available by tapping the "Enter" option.

Before starting to vacuum, the X8 Pro Omni maps out all of the rooms of the house, or the rooms that it is given access to. It's surprisingly good at identifying objects, distinguishing between flooring types, and separating areas into rooms. It can misidentify smaller spaces. For example, it merged my office bathroom into the main office area and split a closet into two rooms when it's one. I can view and edit the map to fix it, create boundaries for the vacuum, identify different rooms, and label furniture. There is a multi-map option for houses with more than one story, or for separate areas.

The X8 Pro Omni is continually scanning its surroundings as it cleans, and it is good at not bumping into furniture or objects. It also does well with pets. My cat loves the robot, and when it vacuums, he'll follow it around and get in its way. The X8 Pro Omni gently nudges him out of its path and continues on with its task.

As the X8 Pro Omni cleans, it shows a white line on the map of where it has vacuumed, so it's easy to ensure that it gets into every nook and cranny that it can reach. Mopping is shown with a more diffuse line over the vacuum line.

There are multiple options for controlling how it cleans. There's a vacuum only mode, a vac and mop mode where it vacuums and then mops at the same time, and a mop after vac mode where it will go around and vacuum first, then mop afterward. The benefit to that last mode is that it'll vacuum before it starts washing the floor, so there's no water from the roller mop getting on carpets or anywhere else.

You can adjust suction power for the vacuuming, water flow rate for the mopping, and the cleaning speed, which increases or decreases the space between the passes that it makes on the floor. Deep cleaning has little space between each pass (it cleans in lines along the floor), and quick clean has more space. There are also options for a single pass or two passes, and you can select specific areas of a room for even more cleaning to get up tough stains.

It's ideal to set up a schedule to have the X8 Pro Omni clean each day or multiple times a week. Depending on how large the area is that it's cleaning, it may need to stop and recharge, and there will be multiple stops to empty the dust bin or wash off the mop. Since it can take some time for it to finish, there is a Do Not Disturb option that prevents it from turning on during specific times of the day, and Auto Resume can also be turned off if you don't want it cleaning half the house, charging up, and then resuming late at night when you're trying to sleep.

With a large house, it would probably make sense to set the robot to clean a room or two each day, which would keep the floors clean without having it run for hours. It can also be scheduled to run when you're out of the house, which lets you avoid the noise, plus there are options for cleaning up eating areas after meals and keeping pet areas clean.

There is a voice assistant built into the X8 Pro Omni, called Yiko. Saying the "Ok Yiko" wake word activates listening mode, and the robot accepts commands to start a clean, continue a clean, stop a clean, go charge, and more.

Yiko is more capable than ‌Siri‌, and can understand commands to vacuum specific rooms, under specific furniture, and multi-step commands like sweep around the pet feeder, then mop. It can re-clean rooms on command, spot clean, and clean at specific times. There's even an option to have it come to where you are and clean, and you can send it away with a "don't clean here" command.

While the X8 Pro Omni is cleaning, you can view the camera to see what it's doing and what it's seeing. When it's not cleaning, you can enter the live view and have it patrol your house and communicate with whoever is in the house, so it's also sort of a mobile security or pet camera. I can direct it to go check in on my cat, using an on-screen remote control, and it can snap photos, take videos, and let me talk to him. It's fun to play with.

I do wish I could have it vacuum/mop while I control it, but that's not an option.

Privacy

Ecovacs is a Chinese company, and this is a product that includes a camera and the ability to map your house, which some users will be wary about. Ecovacs does have a clear privacy policy surrounding data storage, and footage from the camera is stored locally and encrypted.

Visual data can be uploaded to Ecovacs' servers for obstacle avoidance purposes, but this is an opt-in feature. There are multiple privacy controls in the app, with toggles for opting out of data sharing, though some of the opt-outs reduce functionality.

Bottom Line

Unfortunately, all of the robot vacuums that have Matter integration are higher-end models, and it's not a feature that has trickled down to entry level models. The Deebot X8 Pro Omni is over $1,000, and other robots with Matter support and similar features also have the same general price point.

Given that HomeKit-based controls for robot vacuums are limited in scope compared to what you can do in the apps designed for robot vacuums, Matter integration shouldn't be the sole reason to choose a particular product. Maybe it will get better over time, but there are a lot of advanced features you can't get to without the dedicated app, and it makes the most sense to set up a schedule and think little about the robot after that.

Where Matter might be more important is if you want to have a vacuum that interacts in some way with other ‌HomeKit‌ devices, because you can set up multi-device automations. If you want to have the robot vacuum whenever people leave the house, the Home app can do that. You can absolutely clean, mop, and operate the X8 Pro Omni with ‌Siri‌ and the Home app, it's just more efficient to use the Ecovacs app.

Even with somewhat weak ‌HomeKit‌ integration, I do think the X8 Pro Omni is worth considering just for its cleaning capabilities. The roller mop that it has for washing the floor works well, and the suction more than keeps up with a multi-pet household. It's good at avoiding obstacles, and the app does come with privacy controls and policies that are appreciated.

How to Buy

The Deebot X8 Pro Omni can be purchased from the Ecovacs website for $1,300, and it is also available from Amazon. Retailers like Best Buy, Costco, and Home Depot also sell Ecovacs products, so it's worth looking for discounts and promotions.

Note: Ecovacs provided MacRumors with a Deebot X8 Pro Omni for the purpose of this review. No other compensation was received.

If you have been experiencing issues with wireless CarPlay in your vehicle lately, it was likely due to a software bug that has now been fixed.

Apple released iOS 18.4.1 today, and the update's release notes say it "addresses a rare issue that prevents wireless CarPlay connection in certain vehicles."

If wireless CarPlay was acting up for you, updating your iPhone to iOS 18.4.1 should help.

iOS 18.4.1 also includes other bug fixes and security updates.

To update your iPhone, open the Settings app and tap on General → Software Update.

OpenAI today announced the release of new o3 and o4-mini AI models, which the company says are its smartest models to date. o3 and o4-mini can use and combine all ChatGPT tools, including web searches, analyzing files and data with Python, reasoning about visual input, and generating images.

The models have been trained to reason about when and how to use different tools to provide detailed and thorough information, and to better understand and answer multi-faceted questions. They are able to "think" with images, blending visual and textual reasoning.

o3 excels at coding, math, science, and visual perception, and OpenAI says that it's ideal for complex queries where an answer is not immediately obvious, and it is adept at visual tasks like analyzing charts and graphics.

o4-mini is a smaller model that is optimized for quick and cost-efficient reasoning, and it is ideal for math, coding, and visual tasks. It supports higher usage limits than o3. Both of the new models are designed to be more natural and conversational, offering more useful and verifiable responses.

o3, o4-mini, and o4-mini-high are available to ChatGPT Plus, Pro, and Team users as of today, replacing o1, o3-mini, and o3-mini-high. Free users are able to try o4-mini by using the "Think" option in the composer when submitting a query. Rate limits remain the same.

The iOS 18.4.1, iPadOS 18.4.1, macOS Sequoia 15.4.1, tvOS 18.4.1, and visionOS 2.4.1 updates that Apple released today include fixes for two major vulnerabilities, which means you should install the new software as soon as you can.

According to Apple, it is aware of reports that these vulnerabilities may have been actively exploited in the wild. Apple says that the security flaws were potentially used in an "extremely sophisticated attack against specific targeted individuals."

One of the issues impacts CoreAudio, and involves a maliciously crafted audio file. Processing the audio stream in the media file could result in code execution. Apple fixed the memory corruption issue with improved bounds checking.

The other vulnerability affected pointer authentication code, and an attacker with arbitrary read and write capability could bypass the Pointer Authentication features that prevent memory from being tampered with. Apple removed the vulnerable code to prevent the exploit from working.

All of the updates are available today, and focus primarily on the security fixes. iOS 18.4.1 also addresses an issue that could prevent some wireless CarPlay setups from working properly in select vehicles.

visionOS 2.4.1 can be downloaded on all Vision Pro headsets by navigating to the Settings app, selecting the General section, and choosing the Software Update option.

To install an update, the Vision Pro headset needs to be removed, and there is a software progress bar available on the front EyeSight display.

According to Apple's release notes, visionOS 2.4.1 includes bug fixes and security updates, and the software is recommended for all users.

More information on the Vision Pro and ‌visionOS 2‌ can be found in our roundup.

Apple today released tvOS 18.4.1, a minor update to the tvOS 18 operating system that came out last September. tvOS 18.4.1 comes two weeks after Apple released tvOS 18.4, and it is available for the Apple TV 4K and ‌Apple TV‌ HD models.

tvOS 18.4.1 can be downloaded using the Settings app on the ‌‌Apple TV‌‌. Open up Settings and go to System > Software Update to get the new software. ‌‌Apple TV‌‌ owners who have automatic software updates activated will be upgraded to tvOS 18.4.1 automatically.

Apple shares full release notes for tvOS in its tvOS support document, which is updated after each new version of tvOS comes out.

Apple has also released a new version of the HomePod Software 18.4.1 for the ‌HomePod‌ and HomePod mini. ‌HomePod‌ software is based on tvOS.

Google recently came out with the Pixel 9a, a mid-tier Android smartphone that rivals the iPhone 16e that Apple released earlier this year. We picked up a Pixel 9a to see how Google's lower-cost option compares to Apple's more affordable iPhone.

The Pixel 9a joins the flagship Pixel 9 and 9 Pro smartphones that Google released last year, much like Apple added the ‌iPhone 16e‌ to the iPhone 16 lineup. The Pixel 9a is priced starting at $499, so it's $100 cheaper than the $599 starting price of the ‌iPhone 16e‌.

The ‌iPhone 16e‌ and the Pixel 9a don't look all that different, and both feature a minimal design with aluminum frames, a matte back, and a smaller camera setup than the flagship smartphones. The Pixel 9a has a plastic back instead of a glass back, so it's a little less premium but more durable.

While the ‌iPhone 16e‌ has a protruding single-lens rear camera, the Pixel 9a has an almost flush camera bump with two lenses instead of just one. There's a standard 48-megapixel wide-angle lens, and a 13-megapixel ultrawide lens, while the ‌iPhone 16e‌ is limited to a 48-megapixel wide lens. The Pixel 9a and the ‌iPhone 16e‌ both take solid images, and it's tough to tell the difference between them in most situations.

Google wins out when it comes to portrait mode images because of the better depth of field and the people limitation on the ‌iPhone 16e‌, but Apple wins for video because the ‌iPhone‌ has some of the best video stabilization features available in a smartphone.

As for display, the ‌iPhone 16e‌ has thinner bezels and a higher resolution, but the Pixel 9a has 120Hz refresh rate support and an always-on display, features you won't get with the 16e. Android smartphone makers still can't match Face ID even after all this time, so the Pixel 9a also has a fingerprint sensor.

You're probably not going to run into performance issues with either smartphone, though the ‌iPhone 16e‌ may be better at high-performance games. The Pixel 9a unsurprisingly outperforms the ‌iPhone 16e‌ when it comes to AI, because Apple's AI features are just so far behind. Gemini is better than Siri and Pixel Studio beats Image Playground. Google does better at object removal in photos, and there are useful features for choosing the best image, adding people to a photo, and more.

Apple today shared new MacBook Pro ads, promoting features like the nano-texture display option and the long battery life.

The first spot features a man sunbathing on a rooftop with his ‌MacBook Pro‌. The sun is blazing, but the Mac's display remains perfectly visible thanks to the nano-texture display.

Any of Apple's latest ‌MacBook Pro‌ models can be purchased with a nano-texture display option that's designed to cut down on glare when in sunlight and bright indoor lighting. For the anti-glare effect, Apple etches the glass at the nanometer level, and the etching scatters light to remove glare. Adding nano-texture is a $150 upgrade.

Apple's second ad features a man who lost his ‌MacBook Pro‌ charger, but he's unaware of that fact because his battery lasts so long. ‌MacBook Pro‌ models with the standard M4 chip can last for up to 24 hours when streaming video and up to 16 hours when browsing the web, marking the longest battery life in a Mac to date.

Both of Apple's ads link to Apple's "Mac Does That" website, which is aimed at people who are new to the Mac. It walks through all of the different Mac features, and has an FAQ on how to transfer from a Windows PC to a Mac.

When using macOS Finder in List view, you'll see the sizes of individual files – but not folders.
Instead, folders show a pair of dashes (--) in the Size column. macOS skips calculating folder sizes by default to keep List view performance fast, especially in directories with many nested files. But if you want to keep an eye on folder sizes in certain locations, or even globally, there are a few ways to do it. Here's how.

What if you want to use List view and still keep an eye on the size of a handful of folders in a specific location – in Documents, for instance, or in a directory synced to a cloud storage service? Or what if you have a super-fast SSD that can handle the pressure of calculating the size of lots of folders on the fly? Thankfully, there are several ways to make Finder show folder sizes, even in List view.

Enable Calculate All Sizes

Open the folder in question, select View ➝ Show View Options from the menu bar or press the keys Command+J, and check Calculate All Sizes. Finder will now remember your viewing preference for that particular location only.

Turn On Preview Panel

If you're looking for a more global solution for keeping tabs on folder sizes that will work in any Finder view mode, you might consider enabling the Preview panel. To do this, open a Finder window and select the menu bar option View ➝ Show Preview, or press the keys Shift+Command+P.

In the Preview panel, the size of the selected folder always appears immediately below the folder name. If this is the only folder information you want to see in the Preview panel, you can select the menu bar option View ➝ Show Preview Options and uncheck all other metadata options.

Use Get Info

Of course, you may find that relying on the Preview panel to keep a check on individual folder sizes isn't an ideal use of Finder window space. This is where the menu bar option File ➝ Get Info (or key combo Command+I) can come in helpful. Opening a separate Get Info panel lets you see the size of the item in question, regardless of whether it's a file or a folder.

The downside? Each Get Info panel is static and specific to the item selected. Opening several at once can clutter your desktop, since each new window stays open until manually closed.

Use Inspector for Live Folder Info

Fortunately, this inconvenience can be easily solved: Click File in the menu bar and hold the Option key, and Get Info will turn into Show Inspector. Unlike a Get Info panel, the Inspector panel is dynamically updated and will always display information for the active Finder window's currently selected file or folder – including, of course, its size.

In summary, for casual folder-size checking, use the Preview panel. For detailed or multiple folders, enable Calculate All Sizes in View Options. And if you need real-time updates without clutter, use Show Inspector.
