Live doesn't start after OS X update because of broken disk permissions
- Live Versions: ALL
- Operating System: OS X until 10.10.5
After an OS X software update, Live doesn't start correctly anymore.
The OS X disk permissions have been changed by the update and haven't been correctly reset.
The OS X disk permissions need to be repaired.
- Start the Mac's Disk Utility to be found under Applications/Utilities.
- Select the Macintosh HD.
- On the right side, show the “First Aid” tab.
- Select “Repair Disk Permissions”.
If repairing the permissions doesn't solve the problem, a fresh installation of the latest Live version is recommended:
- Remove the Live application folder.
- Delete the following Ableton folders:
Macintosh HD:/Users/[username]/Library/Application Support/Ableton/
- Download the latest Live version.
- Install and re-authorize via your user account.
- If the Live Library was saved at the default location, Live should now detect it. Otherwise, change the path manually in the Library tab in Live's Preferences.
