Upgrade done on a MacBook Air, circa 2017. Took about 2.5 hours to install, bearing in mind that I do not have a high bandwidth Internet connection. No glitches, but I don’t have anything exotic installed on the machine, just the usual Ruby and Rails stack.

A couple of interesting observations:

  • The default shell is now zsh. I had to adjust the Ruby and Rails environment a bit, mainly rbenv, but otherwise no biggie. I need to spend more time with Oh My Zsh, it looks pretty cool.
  • I had to re-install xcode-select
  • Mac updates are set to “auto” as the default. I would like to make that decision, thanks very much, so I changed that setting.
  • The OS Desktop is gone, so as a result there is no built-in calculator. Sure, I can grab my phone and use its calculator, but it’s a bit annoying to have to change to another piece of hardware just to add up a few figures.

I’m actually running Version 10.15.1 at the moment, the upgrade to that version was also uneventful, which is the way we like it.
