Logic Pro X Scanning Audio Units (finalized 0 of 3) - Doesn't Scan and can't open

I added an M-Audio Midi keyboard and the first run though it worked flawlessly. Now I try to open Logic Pro and I get the "Scanning Audio Units (finalized 0 of 3)" pop-up and it never moves from there.


If I abort the scan it freezes and I have to force quit logic Pro.


I've emptied my components folders. I've emptied my vst folders and nothing has worked.

"(finalized 0 of 3)" indicates that there are still 3 plugins installed.


1. Did you search for the two (!) components folders?

  • In the Finder choose Go > Go to Folder, enter

"/Library/Audio/Plug-Ins/Components" into the Go to Folder field, then

click Go.

  • You can also check the Library in your Home folder. In the Finder

choose Go > Go to Folder, enter "~/Library/Audio/Plug-Ins/Components"

into the Go to Folder field, then click Go.

Where are third-party Audio Units plug-ins installed on Mac?

2. Did you restart your computer after emptying the components folder?

3. If you still have problems, start logic without core audio (hold CTRL), then check the plugin manager.

Use startup modifier keys with Logic Pro


Bypass, remove, or rescan Audio Units plug-ins in Logic Pro or MainStage
