Apple has updated OS X El Capitan with a method that allows users to enable TRIM support for third party SSDs, reports MacRumors.

TRIM support allows an operating system to inform a solid-state drive which blocks of data are no longer considered in use and can be wiped internally. If it's off, you may see significantly slower drive writes. This feature is supported on official Apple drives but not on third party drives. A tool called TRIM Enabler previously allowed users to enable support for their own SSDs; however, Yosemite made changes which forced you to disable kext signing to turn on TRIM and if your NVRAM or PRAM gets reset your system refuses to boot.

OS X El Capitan Makes It Possible to Enable TRIM Support for Third Party SSDs

Notably, with the release of OS X El Capitan, forum members have been investigate possible support for TRIM and thankfully found that if "rootless" is disabled, a simple "trimforce enable" command will turn on TRIM for third party drives.

The developer of TRIM Enabler has confirmed this method works and plans to update the software to support it. This is good news for users as long as Apple continues to allow you to disable its new "rootless" security enhancements.

In fact all SandForce controller drives have built in garbage collection and not just Intel. It is still advisable to enable OS-level TRIM.

It is for people like us, who insist on using older MacBook Pro machines because they do not wish to upgrade just because there's a new one out there and people who use Hackintosh builds. We significantly boost system performance by using SSDs. Apple restricted, until now, to have OS-level TRIM support for non-Apple SSDs, which may significantly slow down older SSDs, so we had to use unofficial hacks such as modifying a kext, using TRIM Enabler, etc.
