Having two of everything is actually a pretty decent idea.

Part of the fear of updating though is the time sink.

Even if I attempt to update one mac laptop to the new version (of which I believe there is a new one just released, doesn’t seem long since I last updated…) knowing that I have a safe backup, I dread the thought of spending hours knowing something _should_ be working but is now broken. It can be infuriating. Especially when it’s a pattern/way of working you have become so accustomed to.
