An interesting thing happened. I wanted to try a bigger screen with the iPad, so got the same 27" 4K monitor as my wife. It's great, but showed how limited Stage Manager etc is on iPadOS.

When getting a longer Thunderbolt cable, I found our occasional-use M2 MacBook Air, hooked it up to my dock — with monitor, speakers, split keyboard, trackpad — to try out the latest macOS. And… I like it!

So, experimentally and after 8+ years, I'm back on a Mac. Any suggestions for nifty utilities etc?

@mattgemmell I use Magnet on my 4K screen. Wouldn’t be without it. Otherwise, homebrew as others have said.
