If I remember correctly (it’s been a while) the AU plugin must be installed into the correct location (i.e. /Library/Audio/Plug-Ins/Components or similar) it’s nothing to do with JUCE it’s just how has to be for the plugins to be discovered.
Even with the gain plugin example installed to ~/Library/Audio/Plug-Ins/Components/ I can’t get it to load in the audio plugin host… starting to think it might just be a permissions thing.
Seems that any plugin built with latest JUCE isn’t working… tried downloading the trial of FabFilter’s Saturn 2 and that worked fine, so did one of my own plugins built with an older version of JUCE 6.
Ah I wonder if it’s being made to run out of process and that’s somehow causing the problem. I take it you’re also running sudo killall -9 AudioComponentRegistrar before? does auval work OK?
Sadly still can’t get it to work on my azure pipeline… already wasted the majority of my bank holiday weekend on this so tbh I think I’m just gonna give up and only test vst3 for now.
