Earlier today Apple released OS X 10.10.4 (http://www.macrumors.com/2015/06/30/apple-releases-os-x-10-10-4/), an under-the-hood update to OS X that introduced several bug fixes and improvements. One improvement, according (http://arstechnica.com/apple/2015/06/latest-os-x-update-allows-you-to-enable-trim-for-third-party-ssds/) to Ars Technica, is support for TRIM for third-party SSD hard drives. We previously covered (http://www.macrumors.com/2015/06/12/os-x-el-capitan-trim-support/) TRIM likely coming natively to the next version of OS X El Capitan (http://www.macrumors.com/roundup/os-x-10-11/) but it appears support has already arrived.
http://cdn.macrumors.com/article-new/2015/06/trimforce.pngPhoto via ArsTechnicaWith*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 **tes it's largely because each SSD implements TRIM in a different way, with older disks sometimes acting in a way OS X would **t expect.
