UNABLE TO SEE AUDIO UNIT IN Logic Pro X

Hey there, I have recently installed ReFx Nexus 3.0 - everything installed without a hitch, it it scanned and validated - however I cannot see it under my instruments list. I have tried various tutorials I found online with no help.

MacBook Air 13″, macOS 11.2

Hi there,

Happy to help. Can you do a few things for me?


Be sure to remove all incompatible plugins from the two component folders:

/Library/Audio/Plug-Ins/Components/

~/Library/Audio/Plug-Ins/Components/


Also, be sure to disable failed plug-ins in the Plug-In Manager.


I highly recommend, after you delete plug-ins from the Components folder, to delete your plug-in caches so LOGIC can re-start the scanning process from scratch.


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

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



Keep me posted on your progress,

Eddie G.
