Hi ! In the AudioPluginHost provided by JUCE, we can specify additional folders paths to scan VST or VST3 but, not for the Audio Unit plugins. Even in the AudioUnitFormat::searchPathsForPlugins method, the FileSearchPath argument is ignored.

Is there an explanation ?

You can only install AUs in `/Library/Audio/Plug-ins/Components` or `~/Library/Audio/Plug-ins/Components` - JUCE’s plugin scanning code will scan both of these paths using some OS methods like `AudioComponentFindNext` (see [here](https://github.com/WeAreROLI/JUCE/blob/ceec72457da7bf3180bea00566c5908c7a896257/modules/juce_audio_processors/format_types/juce_AudioUnitPluginFormat.mm#L2775)) so it doesn’t make sense to be able to add more search paths.

Thank you for your answer !  
And it’s not possible to install the Audio Units on an other hard-drive ?

No, I believe they need to be installed on the system hard drive in either of the 2 locations that I mentioned above.
