[Mac-BR] manutenção de desempenho macbook pro

[Marcel Maurício]

UP! na thread novamente só para citar um fato importante que encontrei em
um dos comentários de um SSD no Amazon sobre TRIM no OSX:
OSX INSTRUCTIONS (credit in comments):
------------------------------------
Now, you may have been told (by Apple) that TRIM is only supported with
Apple-installed SSDs. This is categorically not true. For posterity, I am
adding the commands you can use in OSX Lion to allow for 3rd-party TRIM
enabling for your new Mushkin SSD.

Important notes:
1) The information below is for INFORMATIONAL PURPOSES. I am NOT
responsible for any problems incurred.
2) This is ONLY to be used on OSX Lion 10.7.X
3) This is ONLY to be used on a TRIM enabled SSD, such as this Mushkin
drive.

Ok, let's start.

Step 1: Open up Terminal (if you don't know what that is, do NOT proceed)
Step 2: In terminal type (copy paste):

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

Step 3: Hit enter
Step 4: In terminal type (copy paste):

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

Step 5: Hit enter
Step 6: In terminal type (copy paste):

sudo kextcache -system-prelinked-kernel
sudo kextcache -system-caches

Step 7: Hit enter (and wait for up to 15 seconds)

And you're done! To check whether you have succeeded, go to About this Mac
- More Info - System Report - SerialATA - and click on your SSD drive. Trim
Support should now show as enabled, or "yes". Many thanks to Grant Pannell
for posting this on his website (linked below in comments)!
