I guess homebrew isn't going anywhere tho? For me it's the biggest downgrade from Linux pkg management. I'm used to it now, just annoys me from time to time
As much as I love my experience with Homebrew, it is not easy to maintain it so understandably the project tends to only support the latest few OS versions.
This can be problematic for older laptops.
Linux on the other hand tends to work better, even for older computers.
The Homebrew project is also said to be insecure, and have a tendency to be a bit authoritative, as in ignoring criticisms, but thats another story.
zsh + homebrew are the first installs. Other than that, I don't really miss anything.
I bought a Mac after an Ubuntu update broke my Nvidia install on a Dell notebook and I spent the better part of 2 days trying to fix it.
