How do I uninstall Logic Pro from my Mac?
Logic Pro 7 does not include an uninstaller, so if you need to uninstall the software you will have to manually delete the application and its associated files. Some of the items listed below may not be present (depending on what has been installed). Items listed with a star should be double-checked before you delete them, as removing them may negatively affect other programs (namely GarageBand).
To completely uninstall Logic Pro 7 or 8, remove the following files/folders:
*MacHD/Library/Application Support/GarageBand (whole folder)
MacHD/Library/Application Support/Logic (whole folder)
*MacHD/Library/Audio/Apple Loops/Apple Loops for GarageBand (whole folder)
MacHD/Library/Receipts/Logic Pro Sound Library.pkg
MacHD/Library/Receipts/Logic Pro Bonus Sound Library.pkg
**MacHD/Users/(home)/Library/Application Support/Logic (whole folder)
**MacHD/Users/(home)/Library/Preferences/Logic (whole folder)
* = Do not delete if GarageBand is installed on your system.
** = Item will only be present if Logic Pro has been launched on the system.
