I have a MacBook Pro currently running macOS Catalina 10.15.5, and every time I try to download the "Fugue in Void apple fix" file I am unable to open it. Is anyone else having this problem?
The current "Fugue In Void (Mac Fix)" does run on Catalina, at least on 10.15.3. If you can't open the game on Catalina, first check that you have extracted it correctly (the default Mac unzip often messes up permissions, try Keka instead), and that you open it by right-clicking and choosing "open" — double clicking won't work because the app isn't signed.
