Mac OS X 10.10.4 Supports TRIM for Third-Party SSD Hard Drives

Earlier today Apple released OS X 10.10.4, an under-the-hood update to OS X that introduced several bug fixes and improvements. One improvement, according to Ars Technica, is support for TRIM for third-party SSD hard drives. We previously covered TRIM likely coming natively to the next version of OS X El Capitan but it appears support has already arrived. Photo via ArsTechnica With today’s OS X 10.10.4 update, however, Apple has added a command line utility that can be used to enable TRIM on third-party SSDs without having to download and install anything. Called trimforce, the utility can be executed from the OS X terminal, and it requires a reboot to start working.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. Most modern operating systems support TRIM but for Apple's OS X, it has only included support for its OEM SSDs. This means that Mac users looking to install an after-market SSD in a machine originally intended for spinning disc hard drives would run into trouble without the help of other third-party tools. To enable TRIM, a user just has to type "sudo trimforce enable" into the Terminal window. Ars Technica points out that running TRIM prompts a "scary" message from the system, but notes it's largely because each SSD implements TRIM in a different way, with older disks sometimes acting in a way OS X would not

Apple Releases OS X 10.10.4 With 'Discoveryd' Process Removal

Apple today released OS X Yosemite 10.10.4, an under-the-hood update that introduces several bug fixes and performance improvements. Most notably, 10.10.4 includes the removal of the problematic Discoveryd process, which has caused multiple networking issues for some users in OS X Yosemite. The OS X 10.10.4 update can be downloaded through the Software Update mechanism in the Mac App Store. There are also accompanying security updates available for OS X Mavericks and OS X Mountain Lion users. Unlike 10.10.3, which brought Yosemite's first outward-facing changes including the Photos for OS X app and new emoji features, OS X 10.10.4 is a behind-the-scenes update that focuses primarily on fixing bugs and introducing better performance through stability improvements.The OS X Yosemite v10.10.4 update improves the stability, compatibility, and security of your Mac. This update: - Improves networking reliability - Improves Migration Assistant reliability - Addresses an issue that prevented some external displays from functioning properly - Improves the reliability of upgrading iPhoto and Aperture libraries to Photos - Improves reliability when syncing photos and videos to iCloud Photo Library - Addresses an issue that could cause Photos to unexpectedly quit after importing some Lecia DNG files - Resolves an issue that could delay outgoing email messages in Mail - Fixes an issue where a website could prevent the user from navigating away by presenting repeated JavaScript alerts in SafariThe biggest change in OS X 10.10.4 is the elimination of the discoveryd

Apple Seeds Fifth OS X 10.10.4 Yosemite Beta to Developers and Public Beta Testers

Apple today seeded the fifth beta of OS X 10.10.4 to developers and public beta testers, approximately two weeks after releasing the fourth OS X 10.10.4 beta and two months after releasing the first OS X 10.10.4 beta. OS X 10.10.4 has been in testing since mid-April, following the early April release of OS X 10.10.3, which included the new Photos for OS X app. The new beta, build 14E33b, can downloaded through the Software Update mechanism in the Mac App Store or through the Mac Developer Center. OS X 10.10.3 brought several consumer-facing changes including the new Photos for OS X app, a redesigned emoji picker, and diversified emoji, but OS X 10.10.4 appears to be an under-the-hood update that brings performance enhancements and bug fixes. Thus far, OS X 10.10.4 betas have not included outward facing design changes or feature additions, but the last beta introduced a significant behind-the-scenes update that may improve networking performance for users who have experienced issues with OS X Yosemite. Discoveryd, a somewhat problematic networking process that has been linked to multiple bugs in OS X 10.10, was removed in favor of the older bug-free mDNSresponder. It is not clear when Apple plans to release OS X 10.10.4 to the public, but the fact that we've now received five betas suggests we may be nearing the end of the beta testing

Apple Replaces Problematic 'Discoveryd' Process With mDNSresponder in 10.10.4 Beta 4

In today's fourth OS X 10.10.4 beta, Apple made a significant behind-the-scenes change that could result in improved networking performance for some users -- the removal of the "discoveryd" process. As noted by MacRumors forum members and 9to5Mac, in OS X 10.10.4 beta 4, the discoveryd process has been replaced by mDNSresponder. Since OS X Yosemite debuted in October, there have been ongoing complaints about discoveryd consuming CPU resources, draining battery life, and causing issues with Wi-Fi. These problems have lingered for several months, even after multiple bug fixes and performance improvements included in OS X 10.10.1, 10.10.2, and 10.10.3. Discoveryd was introduced with OS X Yosemite, replacing mDNSResponder for managing Mac networking tasks, but it's led to a host of problems like those listed above along with issues like slow wake from sleep, failures to resolve DNS names, duplicate machine names, and more, as detailed in a post earlier this year by Ars Technica. Several developers have also complained about discoveryd in Yosemite, including Instapaper's Marco Arment and Iconfactory's Craig Hockenberry.It's no secret in the tech community that discoveryd is the root cause of so many problems. There are even crazy workarounds. With so many issues, you'd expect some information from Apple explaining ways to mitigate the problems.The removal of the unstable discoveryd process in OS X 10.10.4 beta 4 may improve network stability problems for many users who have been experiencing continual issues. With the removal of discoveryd, Apple has reverted back to

Apple Seeds First OS X 10.10.4 Yosemite Beta to Developers

Apple today seeded the first beta of OS X 10.10.4 to developers, just over a week after releasing OS X 10.10.3 with the Photos for OS X app to the public. The new beta, build 14E7f, can be downloaded from the Mac Developer Center.

OS X 10.10.4 may serve the same purpose. OS X 10.10.3, released last week, was the first major update to OS X Yosemite that brought new features, including the Photos for OS X app, a redesigned emoji picker, and new diversified emoji.
