![]() As for power users, I recommend just buying a new Mac. This been said, I guess Apple would rather prefer to allow their Macs to support 3rd parties SSDs and have Macs secured, than have a lot of hacked Macs and all the internet taking about it.Īlthough, old Macs are getting obsolete due to the absence of current technologies, most of the regular users still can extract a bit more juice of their Macs, so they will find this tool very useful. I believe that Apple had made this decision because after the release of OS X Yosemite, which includes the new kext signing feature, Mac users were disabling this security feature, which when turned off, allows to execute arbitrary code in modified kext extension natively, WHICH was an huge security flaw. This is a huge win for the Mac users community because the people had ask for this a while ago. Yesterday, Apple had released OS X 10.10.4, including on it the new remarkable trimforce tool which allow native TRIM support for 3rd parties SSDs. Sudo kextcache -m /System/Library/Caches//Startup/Extensions.mkext /System/Library/Extensions # rebuild kext cache manually (could take a while) TRIM Enabler from groths is a very small freeware program that you can download and run and 'flip the switch' to turn on TRIM. A: Trim Enabler patches a native OSX Trim driver, which works in the background even when the app is closed or removed. ![]() So they do not endorse using TRIM on non-Apple SSDs, and thier software does not send TRIM commands to non-Apple SSDs. # looks for "Apple" string in HD kext, changes it to a wildcard match for anything Apple has not tested all manufacturers SSDs. # Important: Add "kext-dev-mode=1" as Kernel Arguments or the computer won't boot. Sudo cp /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage.original # Yosemite: for recovering from stop sign on boot screen, please see # Looks for "Apple" string in HD kext, changes it to a wildcard match for anything # Update July 2014: no longer offline, see # Original version by Grant Parnell is offline () # just run "sudo trimforce enable" to activate the trim support from now on! # UPDATE for 10.10.4+: please consider this patch obsolete, as apple provides a tool called "trimforce" to enable trim support for 3rd party SSDs
