Do you copy Apps from system to system, say after a clean install of macOS? This may be why you don't remember downloading the App, as it only needed to happen once for your four systems to be able to use it.

Yes, I do that. But the system at left is the only one that has that app installed. BTW, I now have only two Hacks, at left (Mini-ITX 4) and below (Mini-ITX 3). The other two are now Win 11.
