Since Hi Sierra (I think so), GarageBand 10.12.2 can’t find Virtual CZ (bought at Plugin Boutique). GB opens a window asking to contact the manufacturer.
If I rescan all the AU plugin, it’s the same.
But If I put one other AU working plugin in one track, then GB accepts Virtual Casion CZ! !!
It’s very strange.
How can I (you) fix this problem ?
Best regards, Lucien
