Mainstage Stuck on Initializing JamPack Manager after installing OS Sonoma. I heard this before because many people have this issue but what is the solution? I don't have an old version of Mainstage.
I have this issue as well, Im on Monterrey 12.6.3 trying to reinstall MainStage (uninstalled with cleanmymac trying to solve another issue, it made me reinstall the entire library of sounds every time I launched it). MainStage is stuck initializing JamPack manager.
MainStage, just like Logic, require some basic content to be installed. That download process starts right when this text is displayed. Maybe there is an alert or so hiding behind some window?
