SMC reset and Trim Enabler, a bad combination

Did you apply Trim Enabler patch? Did a SMC/PRAM/NVRAM reset turned your mac unbootable?

If you are stuck at boot you can try to disable trim via Recovery Partition or a bootable OSX Installation USB drive.

Boot into Recovery ( CMD + R ) and open Terminal utility. Type as follows:

rm -rf /Volumes/MyMainMacDiskDriveName/System/Library/Extensions/IOAHCIFamily.kext
cp /System/Library/Extensions/IOAHCIFamily.kext /Volumes/MyMainMacDiskDriveName/System/Library/Extensions/IOAHCIFamily.kext
touch /Volumes/MyMainMacDiskDriveName/System/Library/Extensions
kextcache -u /Volumes/MyMainMacDiskDriveName/

Note: if your 10.10 Partition has a name like “Macintosh SSD” you must enter /Macintosh\ SSD/
