And, it would seem, Apple stuff does the same, with, perhaps, the difference that one can choose to update or not (I'm not sure about that, though...). That's why I'm looking towards Linux, where stuff happens only when I make it happen. I've nothing against updates, but it infuriates me when a system that I'm happy with becomes useless, and I can't roll it back. My budget is limited, so once I've got stuff working, I want to keep it that way. Other than that, I don't mind what the OS is (I've worked successfully with many over the decades...). Unix suited me, but has little appeal now, financially, and supports few programmes I use, so...
