10.8.3 After the update ssd need to open the trim solution

After my ssd update 10.8.3, the trim should be reopened. Using the terminal to open the method is very simple. First open your terminal and enter the following command: 1. For security, this step is a backup driver (you may need to enter a password) sudo cp -r /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.BACKUP 2. Update sudo perl -pi -e 's| (\\x52\\x6F\\x74\\x61\\x74\\x69\\x6F\\x6E\\x61\\x6C\\x00{1,20})[^\\x00]{9}(\\x00{1,20}\\x54)| $1\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00$2| Sg' /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage 3. Open trimsudo kextcache -system-prelinked-kernel After execution, you will be prompted: Kernel file /mach_kernel does not contain requested Arch: i386 ignores it. . . 4. Clear cache sudo kextcache -system-caches 5. Restart the system. After rebooting, the trim has been opened!
