Your Questions, Our Answers – Logic Pro X Keeps Scanning Audio Unit Plugins

logic pro x keeps scanning audio units

Recently one of our readers noticed how Logic Pro X keeps scanning Audio Unit plugins every time he launches the application.

Hey guys,

I had a question. I know you don’t have any forums, and I Googled a bit and not found a solution yet, but lately Logic Pro X keeps scanning Audio Unit plugins every day now. Just wondering if had any troubleshooting posts (or and idea) that might help solve this. The Mac maintenance utilities I am using are Onyx, DiskWarrior and Disc Doctor.

Our answer:

Quick thought:

We sense either Onyx or the Disc Doctor app is removing the Audio Units cache file every time you do disc maintenance, which leads to Logic Pro X rescanning every time you launch the application.

In case of Logic Pro X, the audio units cache file (com.apple.audiounits.cache) resides in

~/Library/Caches/AudioUnitCache

Just to be sure: to access your home/user folder on your Mac, hold down while you select ‘Go’ in Finder’s menu bar. If you could somehow exclude this file from being trashed by the Mac OS X maintenance app, you’d be good!
