Mac at home, Mac/Linux at work. Though I suppose Linux has its foot in the door at home also via the Steam Deck. I haven't spent too much time on its desktop though. Mostly, I do stuff on a MB Air at home and a Mac mini at work.

I seldom use Windows anymore. I have an old gaming PC that ran it, but the Steam Deck is generally more powerful, so it's been resting idle for a while now. There are a few people at work who use Windows, and I occasionally have to do some IT stuff for them on those machines and I hate it!
