Comment désinstaller Logic Studio 9 ?

ou ici

OK. For anyone that wants to / need to uninstall Logic 8 this is where all the files and folders are located.

I have not tried deleting all these files. In theory deleting all the below will remove Logic Studio completely from your system.

HD/Library/Application Support/Logic/
HD/Library/Application Support/Soundtrack Pro/
HD/Library/Application Support/WaveBurner/

HD/Library/Audio/Impulse Reponses/
(Impulse response files for Space Designer reverb unit)

*User*/Library/Preferences/com.apple.logic.pro.plist
*User*/Library/Preferences/com.apple.logic.pro.cs

HD/Library/Audio/Apple Loops/Apple/Apple Loops for GarageBand/
HD/Library/Audio/Apple Loops/Apple/Apple Loops for Soundtrack Pro/
HD/Library/Audio/Apple Loops/Apple/iLife Sound Effects/
HD/Library/Audio/Apple Loops/Apple/Jam Pack 1/
HD/Library/Audio/Apple Loops/Apple/Jam Pack Remix Tools/
HD/Library/Audio/Apple Loops/Apple/Jam Pack Rhythm Section/
HD/Library/Audio/Apple Loops/Apple/Jam Pack Symphony Orchestra/
HD/Library/Audio/Apple Loops/Apple/Jam Pack World Music/
HD/Library/Audio/Apple Loops Index/

Licence for Logic:
/Library/Application Support/ProApps/Logic Studio System ID

I think that's eveyrthing. You can look for receipts for the Logic studio apps and jampacks in
HD/Library/Receipts/
