Ah, the joys of waking up to find the Mac's done an overnight upgrade… and erm, suddenly things stop working. Thankfully, me and Claude managed to work out what the fuck is going on… I'm sharing here, as well as having raised in on https://feedbackassistant.apple.com/feedback/22280434 (that seems to need a login?).

introduction

I like MacOS. It has its flaws, but overall, as a productivity operating system, especially when paired with Apple's ARM chips, nothing really compares. However, there are a few things I find I need to do to get it just right. These are those things. Take the ones you value, leave the rest.

the missing package manager: homebrew

macos shouldve come with a package manager, but for some reason, doesn't -- so the community made one called Homebrew. Go to https://brew.sh, and copy the 1-liner installation script, then paste that into Terminal, type in your password once or twice, download the xCode developer tools, and eventually you'll be good to go. The following all use brew, the cli tool.

Done? OK, let's continue.
