Re-setting the Logic Pro X plug-ins cache manually

Modified on Fri, 19 May 2023 at 05:06 PM

macOS and AU 64-bit format:

Close Logic Pro X.
Using macOS Finder go to “~/Library/Caches/AudioUnitCache/” (without the quotes).
Manually delete the com.apple.audiounits.cache file (to force a complete new plug-ins scan).
Re-open Logic Pro X.
Reboot the computer (mandatory).

After deleting the plug-ins cache file, on the next run, Logic Pro X will re-scan all of your Audio Unit plug-ins, and depending on the number of AU components installed, the process may take several minutes.
