I am writing an installer to put audio plugins in the correct system folders.
Au in /Library/Audio/Plug-Ins/Componets
VST in /Library/Audio/Plug-Ins/VST3
AAX in /Library/Application Support/Avid/Audio/Plug-Ins
I can write the files there if the folders exist, BUT if they do not exist I don’t have permission to create the folders in /Library
