Re: Exs 24 Sample Editor (Not Work...
Are you definitely starting up using a blank/empty project?
(This will help diagnose whether the issue is with certain projects...)
Have you tried restarting your Mac?
Also try this "repair permission" technique:
Finally, I'd recommend trashing the Logic preferences file:
1. Go to [Home folder]/Library/Preferences/
2. Move the file "com.apple.logic.pro.plist" to your Desktop.
3. Launch Logic.
(Logic will create a new preferences file automatically).
Let me know if any of these work.
