I’m on MAC too and I was more wondering why when I unsubscribe a plugin it is still in VCV
Everything is stored in plugins-v1 folder. Unzip in that folder and launch VCV. I did it with a beta from stoermelder and it appears automatically. On the other hand, I tried with a plugin developed for VCV 0.6 and it didn’t worked as some json files are missing.
To remove plugins, unsubscribe it from the Library and delete the corresponding folder.
