Hi Everyone.
I have just received my new (second hand) M1 Mac mini.
Upon starting it up for the first time there seemed something a bit odd about it. Most things seem to work fine but there are a few quirks. Anyway, to cut a long story short, it’s running Mac OS Monterey 12.1 Beta (21C5045a). Why you would sell a computer, second hand, running beta software without letting the buyer know, I have no idea.
Anyway, I would like to keep this. It’s in great condition and I paid a really good price for it. I have done some searches about how to release this machine from the beta program in software update but none of this is available on mine. If I try to reinstall from Recovery mode - same thing. Will only reinstall the beta version. I’m sure there is a simple solution to this but I haven’t been able to find it.
Any help would be much appreciated. Thanks in advance…
