I'm back working on a desktop (2020 iMac) after many years on MacBook Pro. Lost power today a couple of times and realized I didn't think about that. Was wondering why the iMac had crashed :rolleyes:. Aaaany way? What are people using/recommending for battery backup, maybe something that wouldn't look too bad on my desk itself. The black ups boxes are kind of ugly.

A big black ugly UPS box from APC...

Same here.....OP until then you may want to uncheck this restart after power failure so it stays down until power recovers.

A UPS will give you enough time to at least shut stuff down, but you’re unlikely to get more than a few minutes out of actually using it. If you need to do consistent work without power you’re going to need to look at larger/more powerful generators.

I don’t have any specific suggestions except to prepare for the devices to be both large and relatively expensive.

If power doesn’t go out that often, I find a decent surge protector is fine and macOS will handle power disconnections really well, but everyone has their own levels of comfort/paranoia.

I have this :

Works perfectly. But too heavy for a desk. It needs to be on the floor. My NAS + Cisco 2821 + Cisco 2960-S gets something like 20 minutes of battery. An iMac sitting on idle should have the same. Plenty enough time to save and quite, and it has USB so the mac will be noticed when UPS goes online and can shut down by itself.
