Installation of AudioUnits since High Sierra
2019-09-03T12:20:54+00:00
Hey folks, so classic thing, but I still got no answer. Since High Sierra (I think), if you install an audiounit, it isn't recognized / changed in Logic (and other AU hosts) until login / restart. So I tried this:
I took MyPlugin.component version 1.2 and placed it to /Audio/Library/Plug-ins/Components. Opened Logic, ok, auval, ok. So now I executed my "installer" for version 1.3, which basically does this:
rm -r /Audio/Library/Plug-ins/Components/MyPlugin.component
cp -a thenewcomponent/MyPlugin.component /Audio/Library/Plug-ins/Components/MyPlugin.component
RESULT: Logic and auval still think its 1.2! Btw. I checked that the new component 1.3 IS there.
So according to this:
https://developer.apple.com/library/archive/documentation/MusicAudio/Conceptual/AudioUnitProgrammingGuide/AudioUnitDevelopmentFundamentals/AudioUnitDevelopmentFundamentals.html
it should be solved by doing
touch /Audio/Library/Plug-ins/Components
For completeness sake I also did
touch /Audio/Library/Plug-ins/Components/MyPlugin.component
RESULT: No change, Logic and auval still report 1.2.
So I thought let's clear the cache, hard way, like every cache I could, so:
rm -r ~/Library/Caches/*
RESULT: Logic and auval report a version mismatch :D . They apparently realized that the component has changed, but only partly.
So perhaps the component is messed up indeed, right? I restarted the computer.
RESULT: All fine. Nope, the component is and was fine, it's just that restart was needed...
I mean wtf :D. Apple is killing me... Any ideas how that could be solved so that people don't need to restart after every installation/update?

What versions of OSX are affected by the problem? Is it only High Sierra and Mojave?
