It seems like it’s still possible to disable Gatekeeper on macOS 15: https://discussions.apple.com/thread/255759797

I haven’t tried it though. It’s so rare that I want to run something unsigned, I prefer leaving it enabled and then allowing whatever it is I want to run.

All you’ve said is that it’s fine because you can run Windows 10 on old hardware, but somehow being able to run a fully supported version of macOS isn’t good enough.

The point was that Windows is the same.

Apple supports current macOS plus the previous two. If he’s on one of those ( which it sounds like) everything will work just fine.

Only until he gets a keylogger on his computer
