For users looking to upgrade their older Macs with third-party solid-state drives (SSDs), one issue has been a lack of support for TRIM on these drives under OS X. TRIM is a system-level command that allows the operating system and the drive to communicate about which areas of the drive are considered unused and thus ready to be erased and rewritten to. In the absence of TRIM, users can see significantly slower drive writes as the drive begins to fill up.

Officially TRIM has only been supported on Apple's drives, and while tools such as TRIM Enabler have been developed to turn on TRIM for third-party drives, they ran into issues under OS X Yosemite due to Apple's use of kext signing. With this security measure in place, users have had to disable kext signing in order to enable TRIM, and should kext signing be turned back on such as by resetting NVRAM/PRAM during troubleshooting, the user's system will refuse to boot.

Since the developer release of OS X El Capitan on Monday, a number of users interested in TRIM support have been investigating the possibilities for TRIM on third-party SSDs, particularly with the new "rootless" security features that prevent access to many system-level files.

Some users have been playing with various options involving turning off rootless temporarily in order to run utilities like TRIM Enabler, and members of our forum have discovered a simple command to enable built-in support for TRIM on third-party drives that can be enabled once rootless has been disabled. The developer behind TRIM Enabler and others have confirmed the method does work and are making plans to enhance their software to support it.

Enabling TRIM using this method does come with a warning from Apple, as it can cause issues on occasion and the company wants to make sure users are operating it at their own risk.

This tool force-enables TRIM for all relevant attached devices, even though they have not been validated for data integrity while using that functionality. By using this tool to enable TRIM, you agree that Apple is not liable for any consequences that may result, including but not limited to data loss or corruption.

Apple could certainly make changes as development on OS X El Capitan continues, but given the built-in trimforce tool it certainly appears the company intends to allow TRIM to run on third-party SSDs. The "man" documentation for the trimforce command indicates it was introduced in OS X 10.10.4, which remains in developer testing, but forum member mikeboss has determined it is not present in the current developer build.

While most users will never need to deal with this issue, upgrading to an SSD is a popular way to squeeze some more speed and life out of an older Mac, so there is a sizable community of users interested in getting TRIM to function on their third-party drives, and some of them may find TRIM a helpful tool.

To kickoff its 2015 Worldwide Developers Conference, Apple shared a humorous "Backstage" video starring Saturday Night Live alum Bill Hader. Hader took on the role of David LeGary, WWDC's director, prepping for the big show.

As of this afternoon, Apple's uploaded the "Backstage" video to YouTube, giving those who missed the WWDC keynote live stream a chance to watch the opening act.

Apple's Worldwide Developers Conference is wrapping up later this week. During the keynote event, the company debuted iOS 9, OS X 10.11, watchOS 2, and Apple Music.

Apple plans to charge between $9.99 and $14.99 per month for its upcoming on-demand Apple Music service, with 58 percent of its subscription revenues going to record labels. For every $9.99 Apple collects from subscribers in the United States, it will pay out $5.80 to labels. Additionally, Apple pays approximately 12 percent to publishers and/or songwriters, leaving the company with somewhere around 30 percent of the revenue from the Apple Music service.

The figures come from a leaked document shared by Digital Music News earlier this week. In its article, Digital Music News erroneously suggested Apple was paying less to music labels than other streaming music services like Spotify (after failing to take into account the publisher's fee), but as it turns out, the 70 percent that Apple pays out to rights holders is on par with the industry standard.

In some circumstances, the fees provided to rights holders can vary, such as when student accounts are involved or when the Apple Music service is provided through a third-party service like Google Play or bundled into a carrier package. During Apple's three-month free trial period that it provides to all subscribers, it is not required to pay any fees to rights holders.

Profit sharing and value concerns often cause a lot of tension between streaming music services, record labels, artists, and other rights holders. Many artists have complained about the low fees they receive from streaming music services, primarily those with free streaming tiers. Taylor Swift famously pulled all of her music from Spotify last year, claiming that by offering music for free, Spotify was undervaluing her work.

With Beats Music and Rhapsody you have to pay for a premium package in order to access my albums. And that places a perception of value on what I've created. On Spotify, they don't have any settings, or any kind of qualifications for who gets what music. I think that people should feel that there is a value to what musicians have created, and that's that.

Apple does not offer a free ad-supported tier for its on-demand streaming music service, choosing to supplement instead with an accompanying radio service. Apple has even allegedly urged record labels to cease offering deals to services that do offer free ad-supported listening tiers, like Spotify and YouTube.

Apple's focus on paid-only music is unsurprising, given the current state of the streaming music industry. Spotify recently announced 75 million users and 20 million paid subscribers, but Spotify continues to operate at a loss. With more than 800 million iTunes accounts with credit cards attached at its disposal, Apple Music could quickly become one of the most profitable streaming services, as long as Apple can draw in customers.

Apple Music launches on June 30 as part of iOS 8.4.

Apple's iconic Fifth Avenue store in New York City will soon close for renovations and temporarily relocate to the soon-to-be-vacated FAO Schwarz toy store in the General Motors Building, according to the Associated Press. The report does not offer a timeline for the renovation plans.

Apple reportedly plans to renovate about 20 existing retail stores in the United States to accommodate for increased foot traffic, with many stores set to double in size. Apple's flagship Regent Street store in United Kingdom is among the stores that will be renovated, while San Francisco's Union Square store will be relocated.

Apple's iconic Fifth Avenue retail store was last renovated in 2011 when larger, seamless panes of glass were installed. The renovation was completed in November 2011, with before and after pictures and a YouTube video providing a good look at the transition to a more seamless design.

As of this afternoon, many developers and public beta testers running the latest iOS 8.4 beta are seeing popups for Apple's upcoming Apple Music service within the Music app.

When opening the app, there's a popup for Apple Music that prompts users to start a three month free trial. Tapping on that option leads to another screen that lets users choose either an individual plan for $9.99 for a family plan for $14.99, but there's no way to actually sign up for a plan. Choosing a plan simply grays out the option and does not allow users to progress further in the signup process.

These options have been showing up for some users since the latest iOS 8.4 beta was seeded yesterday morning, but many more users are now seeing signs of the Apple Music service as Apple begins to implement backend tools to support subscription signups at launch.

Apple Music will launch on June 30 as part of iOS 8.4, and it will be built into the Music app. The full Apple Music experience includes an on-demand streaming music service, the Beats 1 radio station, and Apple Connect, a social networking service connecting fans and artists.

With iOS 8, Apple introduced Continuity, a set of features that allow iOS devices and Macs to interface in new ways. One of the Continuity features allows the iPad and the Mac to receive both text messages and phone calls, so long as your devices, including your iPhone, are all on the same Wi-Fi network.

In iOS 9, accepting phone calls or text messages on your iPad or Mac routed from your iPhone is getting even better, with the addition of cellular support. With iOS 9, your iPhone no longer needs to be on the same network as your iPad or Mac for call forwarding to work.

That means an iPhone can continue to forward calls to a Mac or an iPad even when it's in an entirely different physical location. So, for example, if you forget your iPhone at home, you can continue to receive incoming calls on your Mac while at work, so long as your Mac is connected to a Wi-Fi network.

The feature is tied to Wi-Fi calling, and as noted by The Verge, T-Mobile is the first U.S. carrier to support cellular Continuity. In iOS 9, T-Mobile devices have Phone settings that can be toggled on to allow calls on other devices.

"Wi-Fi calling for other devices allows other devices signed into your iCloud account to make and receive calls using your carrier account even when your iPhone is not nearby," reads the description of the feature.

On phones from other carriers, this setting reads differently: "Use your iPhone cellular connection to make and receive calls on devices signed into your iCloud account when they are nearby and on Wi-Fi."

Developers running iOS 9 who use T-Mobile can access this feature immediately, and beta testers will receive access in July, when iOS 9 is provided to public beta testers. It is not known if other carriers will implement support for cellular Continuity before iOS 9 launches in the fall.

Apple earlier this week announced a new consolidated Apple Developer Program for iPhone, iPad, Mac, Apple Watch and Safari, combining the previously separate iOS, OS X and Safari Dev Programs into one for a single $99 annual fee. The change should place more emphasis on and increase the security of Safari extensions, but some developers have voiced their frustrations about the new fee.

In particular, developers will now be required to pay $99 per year to distribute Safari extensions through the new Safari Extensions Gallery. Comparatively, the old standalone Safari Dev Program was free and did not charge developers a fee to distribute Safari extensions within or outside of the Safari Extensions Gallery. Chrome and other browsers also do not charge a fee to distribute extensions.

Reddit user honestbleeps shared the email Apple sent to Safari developers:

"Dear Developer,

As a creator of Safari Extensions, you’ve helped enrich the browsing experience for Safari users by taking advantage of development resources through the Safari Developer Program. This program is now part of the new Apple Developer Program, which combines everything you need to develop, distribute, and manage your apps on all Apple platforms.

Your existing Safari Developer Program membership will remain active until July 8, 2015 and your Safari extensions will continue to work for existing users.

You can continue building Safari extensions and bring your creativity to other Apple platforms by joining the Apple Developer Program. Join today to provide updates to your current extensions, build new extensions, and submit your extensions to the new Safari Extensions Gallery for OS X El Capitan. You can also learn how to extend your coding skills to create innovative new apps for Apple customers around the world."

Apple aims to improve the security of Safari on OS X El Capitan by implementing Secure Extension Distribution, meaning that all extensions in the Safari Extensions Gallery will now be hosted and signed by Apple. Safari extensions installed from the Safari Extensions Gallery will be updated automatically, while those distributed outside of the Gallery are ineligible for automatic updating.

Apple has created a page for developers to submit Safari extensions for OS X El Capitan in the fall, and developers can read both the Safari Extensions Review Guidelines and Safari Extensions Development Guide to prepare. Safari extensions available now will continue working for current users, and existing Safari Developer Program memberships will remain active until July 8, 2015.

Safari 9.0 will also feature content blocking extensions for both iOS and OS X, providing users with a fast and efficient way to block cookies, images, resources, pop-ups and other content. Xcode includes a Content Blocker App Extension template that contains code for developers to send their JSON files to Safari that specifies which content should be blocked. A full Safari 9.0 changelog is in the Safari Developer Library.

Code hidden within iOS 9 files hints at upcoming iPhone improvements, suggesting Apple could potentially be planning to introduce a front-facing camera with flash support, the ability to capture 1080p video, and several rear-facing camera capabilities, like Panorama and Slo-Mo modes.

"CAMCaptureCapabilities" files in iOS 9 discovered by developer Hamza Sood have file names like "[CAMCaptureCapabilities isFront1080p120Supported]," which seems to refer to the front-facing camera on the iPhone. At the current time, the front-facing "FaceTime" camera is able to capture 1.2-megapixel photos and record 720p HD video.

There's no indication that these particular file names reflect Apple's upcoming plans for the front-facing camera, but it's possible that these are improvements we may see in the future. The front-facing camera has always lagged behind the rear-facing camera in order to save space, but with the increasing popularity of "selfies," Apple may choose to introduce some major upgrades to the front-facing camera in the future.

Rumors have suggested that the rear-facing camera will be gaining some major improvements with the iPhone 6s and the iPhone 6s Plus, so it's a reasonable assumption that the front-facing camera may also see improvements at the same time. There have been hints suggesting the iPhone 6s and 6s Plus could see the biggest camera jump Apple's ever introduced, adopting near-DSLR image quality.

Apple did recently acquire a company that specializes in dual-sensor cameras that produce better images and are capable of capturing 3D imagery, but it is not known if that technology will make it into the new iPhones. Apple is expected to introduce the two new devices in the fall, perhaps in mid-September, based on past release timelines.
