Annoyed that Apple discontinued support for late 2105 27" iMacs but still hasn't given us a new Apple silicon chip 27" iMac to upgrade too. Now running an unsupported iMac, which still runs amazingly well with an incredible display, but am SOL for OS updates. Yet they still support the 2019 iMac. Doesn't even look like a very significant OS update either. Is there any good reason for this? I wouldn't complain if there was a reasonable hardware upgrade other than the Mac Studio combo, which I definitely don't want.
