Emily HartFlushing AudioUnit cache plist and triggering an isolated AU validation pass.
Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:
- Quit Logic Pro and delete the corrupt cache:
rm -f ~/Library/Caches/AudioUnitCache/com.apple.audiounits.cache - Kill core audio daemon:
sudo killall -9 coreaudiod - Open Logic Pro, navigate to Settings > Plug-in Manager, locate the crashed AU plugin, and click Reset & Rescan Selection.
Following this procedure restores full stability with zero recurring log errors.
