My u-he plug-in does not appear in my host / DAW. What do I do now?

On macOS 10.13 High Sierra and newer, it’s possible that AU plug-ins don’t show up in your host software immediately after installation. In such a case, please completely reboot your Mac once. The next time you launch your host, the new AU plug-in/s should finally show up.

Host applications cache plug-ins so they can load faster and avoid re-scanning every plug-in on startup. The exact procedure required to clear the cache depends on which host application you use. You will probably need to clear your host’s plug-in cache. Don’t worry, all your plug-ins will be re-scanned and available afterwards.

Here are some examples:

Apple Logic Pro X

On macOS versions prior to 10.13 High Sierra, try this first:

• Go to Preferences > AU Manager
• Select the u-he plug-in(s)
• Select Reset & Rescan

If that does not work, quit Logic and try this next:

• Go to /Users/*YOUR USERNAME*/Library/Caches/AudioUnitCache/
• Delete the file com.apple.audiounits.cache
• Restart Logic

Cockos Reaper

Try this first:

• Go to Preferences > Plug-Ins > VST
• Select Clear cache / re-scan

If that does not work, quit Reaper and delete the following files:

• Mac, in ~/Library/Application Support/REAPER/:
  • AU: reaper-auplugins-bc.ini
  • AU: reaper-auplugins64-bc.ini
  • VST: reaper-vstplugins.ini
  • VST: reaper-vstplugins64.ini
• Windows, in C:\Users\*YOUR USERNAME*\AppData\Roaming\REAPER\VST\:
  • reaper-vstplugins.ini

After deleting the files restart Reaper.

Ableton Live

Go to Preferences > File/Folder > Plugin Sources and do the following:

• Turn on Use Audio Units and/or Use VST Plug-In System Folder

If they were already turned on, then do a deep rescan by holding down the ALT key and clicking Rescan.
