Any tips to setting up macOS dotfiles? I set up a new Mac today and was going to go that route but after trying to do a diff of "defaults read" and seeing that its thousands of lines largely unrelated to macOS I gave up and changed the obvious things using the settings menu and now just have to deal with all the other minor differences as they popup.

I can't help with that sorry, I keep the Mac settings on default as they are usually works for me, dotfiles only have terminal/vim/ssh/git settings :|
