In recognition of Safer Internet Day today, Apple has highlighted the company's software features and tools designed to protect children online, such as Screen Time and Communication Safety. The press release was shared in Europe only.
Communication Safety is an opt-in feature in the Messages app on the iPhone, iPad, Mac, and Apple Watch that is designed to warn children when receiving or sending photos that contain nudity. In its press release today, Apple indicated that it is expanding the feature to more regions around the world in partnership with local experts. In recent months, Communication Safety became available in France, Germany, Italy, and Spain, after launching earlier in the U.S., Canada, U.K., Australia, and New Zealand.
When the feature is enabled, photos containing nudity are blurred and the child will be warned, presented with helpful resources, and given the option to message someone they trust for help if they choose, according to Apple.
On its Child Safety page, Apple assures that Communication Safety is private and secure:
Messages analyzes image attachments and determines if a photo contains nudity, while maintaining the end-to-end encryption of the messages. The feature is designed so that no indication of the detection of nudity ever leaves the device. Apple does not get access to the messages, and no notifications are sent to the parent or anyone else.
In December, Apple announced that it abandoned its controversial plans to detect known Child Sexual Abuse Material (CSAM) stored in iCloud Photos. Communication Safety is unrelated to those former plans and is on-device only, according to Apple.
Apple has reportedly considered releasing a new top-of-the-line iPhone alongside future Pro and Pro Max models, tentatively referred to as "iPhone Ultra," and one designer has taken it upon himself to envision what such a device could potentially look like.
German industrial designer Jonas Daehnert came up with this impressive-looking concept (pictured) by marrying design elements of the Apple Watch Ultra with a smaller imagined iPhone Pro model, which he describes as "12mm+ thick – the Ultra concept."
Like Apple's more rugged Apple Watch, Daehnert's titanium iPhone chassis features rounded edges with a flat upper rim that sits flush with the display. Elsewhere, there are protruding Side and Volume Up/Down buttons reminiscent of the watch's crown guard. The extra thickness of the chassis presumes a larger internal battery.
Other aspects of the Ultra design language that have been adopted for Daehnert's concept include a ruggedized Ring/Silent switch, a programmable Action button on the lower-left side, and a USB-C port located on the bottom with identical "International Orange" accent, sat in between expanded speaker grilles.
"I have no idea about all the leaks," Daehnert admitted when sharing the concept on Twitter. "It was just an exercise to see if it's possible to adapt the Watch Ultra design language."
Apple has discussed selling a new top-of-the-line iPhone alongside the Pro and Pro Max models in 2024 at the earliest, according to Bloomberg's Mark Gurman. Based on this timeframe, the device would be part of the iPhone 16 lineup or later.
Gurman previously said there was "potential" for an iPhone 15 Ultra that would replace the iPhone 15 Pro Max this year, but he has since revised that prediction, suggesting Apple might release an even higher-end "Ultra" model above both Pro variants by next year at the earliest.
Gurman speculated that the device could feature additional camera improvements, a faster chip, a larger display, and perhaps a portless design without Lightning or USB-C. He also said the device would be "pricier" than the iPhone 14 Pro Max, which starts at $1,099.
Separately, rumors suggest that iPhone 15 Pro models could feature thinner, curved bezels in comparison to the iPhone 14 Pro models, producing an Apple Watch-like appearance. Rather than stainless steel, the iPhone 15 Pro models are also rumored to use a titanium frame, like the Apple Watch Ultra. Titanium is lighter and more durable than stainless steel. It is, however, also more expensive.
Mozilla is working on a non-WebKit version of Firefox for iOS in anticipation of changes to Apple's platform rules, The Register reports.
Mozilla's GitHub repository contains code for the iOS version of Firefox with references to GeckoView, a wrapper for Firefox's Gecko rendering engine. Apple's App Store rules insist that browser apps on iOS and iPadOS must use its own WebKit browser engine, meaning that any version of Firefox based on Gecko could not be released under Apple's current policies.
The app, which contains a settings page for toggling GeckoView, could be for internal testing, but postings from Mozilla software developers on GitHub suggest that it is for a "secondary project," with open discussion of "proper Gecko Firefox on iOS." Last week, it emerged that Google's Chromium team is working on a new browser for iOS based on Blink, seemingly in expectation of changes to Apple's platform rules.
In the face of growing antitrust scrutiny, most recently by the Biden administration, Apple is rumored to be preparing to drop its browser engine restriction alongside broader measures to enable sideloading and third-party App Stores in Europe. The main motivator of the move is the European Union's Digital Markets Act, which is expected to compel Apple to make major platform rule changes as soon as next year. Similar legislation has been recommended by antitrust watchdogs in the United States, United Kingdom, Australia, and Japan.
Update: In a statement emailed to The Register, a Mozilla spokesperson said, "We abide by Apple's iOS app store policies, and are simply doing some exploratory work to understand the technical challenges for Gecko-based browsers on iOS if those policies were to change. We hope the day will come when people can freely decide to use the browser of their choice, including the opportunity to select the engine that underpins it."
Apple will hold its annual AI summit for employees next week at Steve Jobs Theater, the first fully live in-person event at the company's Apple Park headquarters since the pre-COVID era.
The summit is similar to Apple's Worldwide Developers Conference, but for employees only, according to Bloomberg's Mark Gurman, who shared news of the scheduled event in a tweet.
As well as inviting staff to the Steve Jobs Theater, the in-person summit will also be live-streamed to employees unable to attend, similar to the way the company held public product announcement events before the pandemic hit.
The last fully live, fully in-person product event was for the iPhone 11, which was held on Tuesday, September 10, 2019. Whether the AI summit is a sign that future product events will finally return in their traditional guise is now the question on many people's lips.
Apple invited a limited number of developers to attend WWDC 2022 at Apple Park, but the event itself was pre-recorded, with no in-person presenters to showcase Apple's latest creations. Members of the media were also invited to the iPhone 14 unveiling this past September, but that keynote was pre-recorded, too.
Interestingly, the event will be held in the Steve Jobs Theater at the Apple HQ and the in-person event will be streamed to employees as well. So, essentially how Apple held media events pre-Covid. Have to wonder if Apple will also return to that for public product launches. https://t.co/uhLv4se9oW

As Gurman notes, the latest AI summit comes at a time of much tech industry excitement surrounding the Microsoft-backed ChatGPT artificial intelligence chatbot and Google's recent announcement that it is releasing its own LaMDA-powered AI chatbot, called Bard.
Google is adding the technology behind Bard to the Google search engine to enable complex queries to be distilled into digestible answers, and Microsoft is expected to follow a similar path by integrating ChatGPT into Bing Search.
WhatsApp has announced some new features for Status Updates, which allow users to share ephemeral updates with friends and close contacts on the popular encrypted chat platform.
First up is Private Audience Selector, which allows users to choose who views their status updates. This isn't technically new, since users are already able to control who sees their status updates when sharing them, but this implementation provides a more customized experience. The most recent audience selection is saved and used as the default for the next status update.
Next, Voice Status. Using this feature, users can share voice notes of up to 30 seconds via their status. WhatsApp describes it as offering a way of sending more personal updates, especially if users feel more comfortable expressing themselves by talking rather than typing.
Status Reactions allow users to react to status updates from friends and close contacts by swiping up and tapping one of eight emojis, including Heart-Eyes, Face with Tears of Joy, Face with Open Mouth, Crying Face, Folded Hands, Clapping Hands, Party Popper, and One Hundred Points. WhatsApp says this was the number one feature that users requested.
New Status Profile Rings make it easier to see status updates right within chat lists, group participant lists, and contact info, thanks to a ring around a user's profile picture whenever they share a status update.
Lastly, new Link Previews on Status mean that whenever a user posts a link, a visual preview of the link's content is available, giving contacts a better idea of what the link is before they click.
As WABetaInfo notes, some of these features are not exactly new, but they have been added to the list of recent improvements for status updates to highlight WhatsApp's commitment to improving the user experience.
WhatsApp says these updates have started rolling out to all users globally and will be available to everyone in the coming weeks.
Update: Microsoft says that it has "applied mitigation throughout the affected infrastructure, and we're starting to see gradual recovery," although there are still some sporadic reports of issues accessing email.
Update 2: Microsoft now says "availability is at 99.9%, with full restoration almost complete."
Microsoft says it is investigating a problem with its Outlook email service after users in the United States started reporting issues when accessing, sending, or searching emails.
DownDetector lists close to 2,000 incidents reported by users trying to access the platform since around 11.00 p.m. Eastern Time, with a drop in incidents reported by the early hours of Tuesday.
"Users primarily hosted in the North American region attempting to access Outlook.com may be unable to send, receive, or search email. Additional functionality such as Calendar consumed by other services such as Microsoft Teams would also be affected," said Microsoft in an update on its status page.
The company tweeted that a "recent change" was contributing to the cause of impact, and it is working on potential solutions to restore the service's availability. We'll update this article when the outage is reported as fixed.
Following the release of the Mac mini and the MacBook Pro with M2 Pro and M2 Max chips, Apple's platform architecture VP Tim Millet and product marketing VP Bob Borchers did an interview with TechCrunch's Matthew Panzarino to discuss the new technology, the transition away from Intel, the future of gaming on the Mac, and more.
With the followup to the M1 chip line, Millet said that Apple did not want to set a precedent of a few percentage points of gain with each new chip generation. Instead, the company aimed to push to the limits of technology as far as it could.
"The M2 family was really now about maintaining that leadership position by pushing, again, to the limits of technology. We don't leave things on the table," says Millet. "We don't take a 20% bump and figure out how to spread it over three years...figure out how to eke out incremental gains. We take it all in one year; we just hit it really hard. That's not what happens in the rest of the industry or historically."
Borchers said that by moving Mac chip design in house, Apple is able to bring silicon, software, and hardware together without relying on outside vendors. Being able to work alongside designers, the hardware team, and the software team "makes all the difference" in Apple's ability to "really target" and add "things that matter" to Macs.
On the topic of Apple's former partnership with Intel, Millet and Borchers praised the company's willingness to accommodate Apple's needs, with Millet also suggesting that the relationship between Apple and Intel ultimately benefited Apple's competitors.
"Intel was a great partner through the years where we shipped the Intel machines. They were very responsive; they really actually were inspired by the direction that Apple pushed them. And I think our products benefited from that interaction. Of course, our competitors' products benefited from that interaction as well sometimes," notes Millet.
As for gaming on the Mac, Borchers says that Apple feels gaming is getting better with each M-series chip release. He said that Apple is adding in new APIs and expanding Metal with Metal 3, so there's "tremendous opportunity" for game makers.
Apple plans to continue to look at chip configurations and components through a gaming lens, and Millet said that while Apple is taking a "long view" on turning the Mac into a gaming platform, work began with the first days of the Apple silicon transition.
"The story starts many years ago, when we were imagining this transition. Gamers are a serious bunch. And I don't think we're going to fool anybody by saying that overnight we're going to make Mac a great gaming platform. We're going to take a long view on this."
According to Millet, Apple is working to build an installed base of strong GPUs. Apple wants the full Mac lineup to have "very capable GPUs," from the MacBook Air to the Mac Studio with M1 Ultra. He also believes that developers haven't yet adapted to M-series chips. "Game developers have never seen 96 gigabytes of graphics memory available to them now, on the M2 Max," said Miller. I think they're trying to get their heads around it, because the possibilities are unusual."
Panzarino's full interview, which can be read over at TechCrunch, covers additional topics that include the transition to Apple silicon, how the iPad Pro led to Apple's Mac chips, the relationship between teams, optimizations in design cycles with Apple silicon, the best time to buy a Mac, and the value of the Mac mini.
Popular speaker company Sonos is developing new high-end smart speakers that will compete with Apple's HomePod and HomePod mini, according to reports from The Verge. The Era 300 and the Era 100 will launch in the coming months, and have been in development since mid-2022.

The multidirectional Era 300 will be the new Sonos flagship speaker, featuring support for Dolby Atmos and spatial audio tracks. The Verge says that the speaker will offer "the richest fidelity of any single speaker" in Sonos' history. Other features will include USB-C line-in, Wi-Fi 6 support, and possibly, Bluetooth playback.
Fewer details are known about the Era 100, but both of the new speakers will have a refreshed design, automatic tuning, and sound optimization. The Era 100 could be a replacement for the more affordable Sonos One.
There is no launch date for the new Era speakers, nor have price points leaked. The speakers will compete with the $299 HomePod 2, which came out last week. Sonos is also developing a second-generation "Move" speaker that will replace the current model, and it is planning to enter a new product category in 2023 that is as of yet unknown.
Apple plans to release Beats Fit Pro in new Volt Yellow, Coral Pink, and Tidal Blue colors, according to leaker @Jioriku. The colors have not been announced yet, but we have spotted listings for the new colors on several Apple reseller websites in Europe.
First released in November 2021, the Beats Fit Pro feature flexible wingtips for a more secure fit in the ear. The fitness-oriented earbuds have a similar design and features as the AirPods Pro, including silicone ear tips, active noise cancellation with a "Transparency" mode, spatial audio with dynamic head tracking, an H1 chip for one-tap pairing and automatic switching between Apple devices, hands-free "Hey Siri" support, and more.
Beats Fit Pro are currently available in Beats Black, Beats White, Stone Purple, and Sage Gray color options for $199.99, and the new colors would likely be sold for the same price. On Amazon, the earbuds also remain available in limited-edition Moon, Dune, and Earth colors designed in collaboration with fashion designer Kim Kardashian.
Update: A tipster has provided MacRumors with alleged images of the new Beats Fit Pro colors.
Apple's M1 iMac (8-Core GPU, 256GB) has returned to its all-time low price of $1,299.99 in select colors on Amazon, down from $1,499.00. You can get this sale in Yellow, Purple, Orange, Pink, and Green, and most are available to ship soon from Amazon.
Note: MacRumors is an affiliate partner with some of these vendors. When you click a link and make a purchase, we may receive a small payment, which helps us keep the site running.
We last saw this deal appear in January, making today's sale only the second time in 2023 that we've tracked this record low price on the M1 iMac. Select colors, like Orange, can be delivered as soon as February 8 to most residences in the United States.
For more storage, Amazon also has the M1 iMac (8-Core GPU, 512GB) for $1,499.99, down from $1,699.00. This is another match for an all-time low price on the M1 iMac, and it's available in two colors: Green and Pink.
Apple today released new tvOS 16.3.1 and HomePod 16.3.1 software updates, with the software coming two weeks after the tvOS 16.3 and HomePod 16.3 updates were released.
According to Apple's release notes for HomePod software 16.3.1, the update includes general performance and stability improvements. Notes for tvOS 16.3.1 are unavailable as of yet, but are probably similar to the HomePod notes.
The tvOS 16.3.1 update can be downloaded over the air through the Settings app on the Apple TV by going to System > Software Update. Apple TV owners who have automatic software updates turned on will be upgraded to tvOS 16.3.1 automatically.
HomePod software is installed automatically on the HomePod unless the feature is disabled, but the HomePod can also be manually updated in the Home app by following the instructions in our HomePod update how to.
Microsoft Authenticator is no longer available on the Apple Watch following an update to the app released on the App Store today.
"This update removes Microsoft Authenticator from Apple Watch," reads the release notes for the update. Microsoft notes that in the Apple Watch's notification settings, you can still choose to mirror iPhone alerts from the app to your Apple Watch.
Primarily used for signing into Microsoft accounts with two-step verification enabled, the Microsoft Authenticator for iOS gained an Apple Watch companion app in 2018. Microsoft previously announced that the Apple Watch app would be discontinued in early 2023.
The Microsoft Authenticator app for Apple Watch joins a long list of third-party watchOS apps that have been discontinued over the last few years, either because of perceived redundancy or lack of user uptake. Other notable Apple Watch apps that have been discontinued include Twitter, Instagram, Target, Trello, Slack, Hulu, and Uber.
Apple is continuing development on a reverse wireless charging feature that would allow the iPhone to charge other devices like the AirPods, according to a new report from 9to5Mac that cites sources with knowledge of Apple's plans.
Apple is said to be working on an "advanced bilateral wireless charging technology" for a future iPhone. The company originally intended to implement the functionality in the iPhone 14 Pro models, but it wasn't "finalized in time."
The site claims that Apple is creating a "wireless power out" firmware that is the basis for the two-way wireless charging feature, and while exactly what that means is unclear, it is apparently a "key aspect of the ongoing testing and engineering" of reverse wireless charging.
To implement an option that would let the iPhone charge other devices, Apple needs to optimize aspects like charging speed, heat dissipation, and charging efficiency. Apple is designing a "special user interface" for bilateral wireless charging, which is similar to the interface used for MagSafe accessories.
We've heard rumors of reverse wireless charging (or bilateral wireless charging, as it's sometimes referred to) several times over the past few years. Bilateral wireless charging was rumored to be an iPhone 11 feature ahead of the device's launch, but it did not materialize. Rumors later suggested that Apple had abandoned the feature at the time because the charging efficiency did not match Apple's requirements.
When attached to an iPhone magnetically, the MagSafe Battery Pack is able to charge using passthrough technology when the iPhone is plugged into a Lightning cable. Charging for AirPods and other devices could eventually work in the same way, connecting to the back of the iPhone and charging at the same time an iPhone does. Apple competitor Samsung has had a reverse wireless charging option for several years now, and it allows a Samsung smartphone to charge any Qi-based device, including another smartphone.
9to5Mac claims that reverse wireless charging could be delayed again or scrapped altogether, so there is no concrete detail on when we might see such a feature launch. We've already heard numerous rumors about the iPhone 15 lineup, and so far reliable sources like Apple analyst Ming-Chi Kuo and Bloomberg's Mark Gurman have made no mention of reverse wireless charging, so it may not be something that we see in 2023.
Apple today shared a third Apple TV+ ad starring Timotheé Chalamet, with the actor again lamenting that he does not have an Apple TV+ show or movie.
In the "Ladybug" spot, Chalamet sits in a garden going through Apple TV+ content and complimenting the actors that Apple has worked with. "Apple, you wound me," he says. "Clearly you understand art."
"Beauty is such a fragile thing," he goes on. "Often overlooked." At the end of the ad, Chalamet once again begs Apple to give him a call.
This is the third ad that Apple has shared starring Timotheé Chalamet, and it follows both the "Call Me" and "A Taste" ads that were shared in January. Apple's ad campaign appears to be leading up to the announcement of an Apple TV+ show or movie starring Chalamet, though nothing has been announced at this point.
Apple used a similar advertising tactic with Jon Hamm before he was announced as a cast member of "The Morning Show" in 2022.
Samsung and LG are preparing their factories for mass production of the first iPads with OLED displays, according to South Korea's ETNews. The report describes the displays as "hybrid" panels, as they use a combination of flexible and rigid OLED technologies.
Young previously said the new MacBook Air and iPad Pro models would use "two-stack" OLED displays with two red, green, and blue emission layers for increased brightness. He also said all of the devices would support ProMotion for up to a 120Hz refresh rate.
All existing iPads and MacBooks are equipped with backlit LCD displays, whereas OLED displays have self-emitting pixels and do not require backlighting, allowing for higher contrast ratio, greater color accuracy, and lower power consumption. Apple already uses OLED displays for the latest Apple Watch and iPhone models, excluding the iPhone SE.
Meanwhile, the Apple Watch Ultra is expected to switch to a microLED display in 2024, and other Apple products will likely follow over the course of several years. microLED will be the next display technology that Apple adopts after OLED, paving the way for even higher contrast ratio, increased brightness, and lower power consumption.
It's been a few months since we've seen all-time low prices appear for Apple's 2022 iPad, and today Amazon has finally introduced some of the first major deals of the year on the tablet.

The iPhone 15 Pro models will feature a "buttonless design" thanks to additional Taptic Engines, according to multiple corroborated reports, so what do we know about the change so far?
Apple analyst Ming-Chi Kuo was first to report that the volume and power buttons on this year's two high-end iPhone models will adopt a solid-state design, similar to the iPhone 7's home button, replacing a mechanical button design that physically depresses. Apple uses a similar method for its Mac trackpads, which do not physically move and simply mimic the feeling of being pressed with small vibrations.
The new iPhones will reportedly feature additional Taptic Engines on the internal left and right sides to provide physical feedback to users, making it seem as though they are pressing real buttons. The change means that the number of Taptic Engines in each iPhone will increase from one to three.
Barclays subsequently appeared to corroborate Kuo's report, saying that Apple supplier Cirrus Logic may have hinted at iPhone 15 Pro models getting haptic buttons in 2023 – something Kuo later noted with specific mention of Cirrus Logic benefiting from Apple orders to bring the feature about this year. Analyst Jeff Pu has similarly said that the iPhone 15 Pro models will feature solid-state volume and power buttons with haptic feedback thanks to two extra Taptic Engines, meaning that there seems to be a growing consensus among analysts about the change.
The Taptic Engine in the iPhone 6S – the first iPhone model to feature the component.
Apple was rumored to be planning to transition the Apple Watch to solid-state buttons several years ago, but the switch never took place. At the time, it was said that solid-state buttons would improve water resistance and take up less internal space, but it is not clear if that would be the case for the iPhone since sufficient space for two more Taptic Engines will be required.
It is as yet unclear how the new haptic buttons will work through cases, especially if they require direct touch contact. Likewise, there will need to be solutions to accommodate device recovery in situations the iPhone may not be working as expected.
iPhone rumors from 2021 suggested Apple could move back to round volume buttons like the iPhone 4, 4S, 5, and 5S models, so it seems plausible that such a change could finally occur this year hand-in-hand with the switch to solid-state buttons. Round buttons would not only have a larger surface area for the touch contact required for haptic buttons, but would also be visibly different from any iPhone models in recent years to overtly flag the presence of the new feature. Leaked iPhone 15 Pro schematics do not clearly show whether the device will have round or oblong volume buttons.
Last year, Apple stressed that enabling iOS 16's "keyboard haptics" feature could drain battery life when enabled, and the feature is off by default. Any hardware or software feature on an iPhone obviously consumes battery life, but the fact that Apple felt it was worth explicitly mentioning for keyboard haptic feedback may indicate that the additional power the Taptic Engine uses is relatively significant. As such, the battery life impact to power two extra Taptic Engines and hundreds of additional daily uses in the iPhone 15 Pro remains an open question.
The iPhone 15 and iPhone 15 Plus are expected to retain traditional clickable volume and power buttons, so it seems likely that Apple will have to tout some kind of meaningful improvement or new functionality to successfully upsell customers to the buttonless design. The iPhone 15 Pro models are also rumored to feature a titanium frame, a USB-C port, new Sony image sensors, periscope telephoto camera technology, 8GB of memory, a 3nm "A17 Bionic" chip, and more.
