I've even completely uninstalled CursoSense now. Unfortunately, that doesn't change anything.
Yes, that's really good news. I'm assuming SIP is turned on. But it is strange. It doesn't work on an old (poorly secured) system, but it does work on a new one?
Is Golden Gate still in beta? Could this be a gap that will be fixed soon?
I just checked the macOS code (which is open source for this part). It seems like ventura had a bug which prevents this from working that was fixed in macOS 14. So you won't need golden gate (which will be released final tomorrow) but you need a newer version than 13.
Okay, thanks for your help 
Then I really don't have any compelling reason left not to switch to Golden Gate. Ah, unless my old M1 (16 GB) isn't compatible. In that case, I'd stick with the highest possible version of macOS.
M1 will run just fine on GoldenGate 
Good, if it doesn't work, we'll see each other in court or in the boxing ring... just kidding, thanks, Andreas.
Always create backups before upgrading
