7. Installed Plugins not shown in the Plugin list on the Mac

Modified on Mon, 08 Jan 2024 at 06:38 AM

The MP host will scan 

(by scan we mean that it read and display just the filenames at first and fully scan a plugin once you choose to load/use the plugin)

  • the AU plugins in /Library/Audio/Plug-Ins/Components 
  • the VST2 plugins in /Library/Audio/Plug-Ins/VST
  • the VST3  plugins in /Library/Audio/Plug-Ins/VST3


If the VST3 plugins are not shown in the MP Host list, navigate to the host.properties folder and rename it or delete it.

Close any MP Host instances you have running.


Then reset the permissions on the VST3 folder by running in the Mac terminal:

sudo chmod -R 777 /Library/Audio/Plug-Ins/VST3/
enter your password and hit enter. It should not produce any output on the terminal.
Then
sudo chmod -R 777 /Library/Audio/Plug-Ins/VST3/*.vst3

enter your password and hit enter. It should not produce any output on the terminal.


Then reopen the MP Host Audio FX plugin and you will need to choose the target monitor from the right click menu. Then open the Plugin List and choose Quickscan. It should show all the VST3 plugins in the plugin list.

As you may have noticed it has generated a new host.properties file.


For more information please see this article on how the MP Host scans and finds plugins.


Plugins also may be removed from the plugin list (after you scan or try to try to load them once) if they are not universal binaries (Apple Silicon ARM and x86). You can find if a plugin is built for both architectures by running lipo -info PLUGIN_PATH in a terminal

For example: lipo -info /Library/Audio/Plug-Ins/VST3/reverbA.vst3
