Hi, this should be fixed in a newer not-quite-released-yet version:
Instructions to fix:
Download these two files and extract with the built-in Archiver tool in macOS (avoid a third-party one, since it might extract symlinks and permissions incorrectly):
https://fs-uae.net/files/FS-UAE/Stab..._x86-64.tar.xz
https://fs-uae.net/files/FS-UAE-Laun..._x86-64.tar.xz
Move FS-UAE.app and FS-UAE-Launcher.app from the respective FS-UAE[-Launcher]/macOS/x86-64 directories to /Applications and delete the remaining extracted files.
