Mac OS is still my system of choice, but I don’t have as much confidence in it as I would like.
The big thing from around fifteen years ago is the mixed modes for autosave, where they sort of half heartedly changed the language around save/save as and just sort of… left it. Some apps use their new (for the 2010s) auto save system and some don’t. And it’s up the the user to muddle through. Weird. And there are many half baked things like this in the OS now.
Mac hardware, on the other hand, has never been better than it is right now!
