Dice di modificare il kext e non usare Trim Enable !!
STEP 10: ENABLE TRIM
Trim is required for most SSDs to operate efficiently during data writes. Apple only enables TRIM on their own specific SSDs. I recommend enabling TRIM to achieve optimum data rates, unless you are sure your SSD has sufficient garbage collection. DO NOT USE TRIM ENABLE APP! I have seen issues with this and it is too generic. Instead, use some good old UNIX commands. Open up the Terminal and type the following.
BACKUP ORIGINAL FILE:
sudo cp /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage /IOAHCIBlockStorage.original
ENABLE TRIM SUPPORT:
sudo perl -pi -e 's|(\x52\x6F\x74\x61\x74\x69\x6F\x6E\x61\x6C\x00).{9}(\x00\x51)|$1\x00\x00\x00\x00\x00\x00\x00\x00\x00$2|sg' /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage
CLEAR KEXT CACHES:
sudo kextcache -system-prelinked-kernel
sudo kextcache -system-caches
REBOOT!
