建議暫時勿在Lion使用TRIM Enabler(1.0 or 1.1)

[cafpeter]

我簡單的用中文描述一下步驟好了，以下的指令都需在"終端機"內執行，就依步驟1~4的順序，完整複製(請從最左上拖拉到最右下，不要多也不能少)每個代碼框內的指令、貼在"終端機"執行

若您不懂怎樣用終端機，建議您找個懂得的朋友來代勞，這些指令我都親身實作過無誤，但要是出了任何問題，請恕在下無法負責

1. Backup the file we’re patching (將原始檔案備份)

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

2. Patch the file to enable TRIM support (修改系統檔案，解除原本TRIM只支援Apple出的SSD的限制)

sudo perl -pi -e 's|(\x52\x6F\x74\x61\x74\x69\x6F\x6E\x61\x6C\x00{1,20})[^\x00]{9}(\x00{1,20}\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

3. Clear the system kernel extension cache (清除快取)

sudo kextcache -system-prelinked-kernel

sudo kextcache -system-caches

4. Now Reboot! (重開機，到此就ok囉!)



下列的指令是回復用的，沒必要的話，無需執行

a) If in the future you want to disable TRIM support 若想關閉TRIM功能 (不太清楚為何會有人想關閉，開著應該是無妨的，除非是做測試對照用)

sudo perl -pi -e 's|(\x52\x6F\x74\x61\x74\x69\x6F\x6E\x61\x6C\x00).{9}(\x00\x51)|$1\x41\x50\x50\x4C\x45\x20\x53\x53\x44$2|sg' /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage

sudo kextcache -system-prelinked-kernel

sudo kextcache -system-caches

b) If something goes horribly wrong, restore the backup (若發生啥慘劇想復原到原本的狀態)

sudo cp /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage.original /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage
