I running a late 2012 mac mini with 2.5 ghz I5, 16 gb ram with a 256 ssd and Catalina. It’s a great piece of kit, is super quick and really well sorted. I’m not too technical but I do understand it is near end of life and even though Apple support still gives me help they do tell me the old girl hasn’t got much time left. So…do I bite the bullet and upgrade to the M1 and Big Sur or do I risk a dark unsupported Big Sur upgrade…whatever that is. Any help from you chaps in the know would be much appreciated. Best garno
