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. 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. 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) # looks for 'Apple' string in HD kext, changes it to a wildcard match for anything

# Important: Add 'kext-dev-mode=1' as Kernel Arguments or the computer won't boot. Open 'terminal app' and enter this command 'sudo trimforce enable' select YES, YES and reboot when complete. 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
