Setup nix, nix-darwin and home-manager from scratch on an M1 Macbook Pro
###
### [2023-06-19] UPDATE: Just tried to use my instructions again on a fresh install and it failed in a number of places.
###. Not sure if I'll update this gist (though I realise it seems to still have some traffic), but here's a list of
###. things to watch out for:
### - Check out the `nix-darwin` instructions, as they have changed.
### - There's a home manager gotcha https://github.com/nix-community/home-manager/issues/4026
###
# I found some good resources but they seem to do a bit too much (maybe from a time when there were more bugs).
# So here's a minimal Gist which worked for me as an install on a new M1 Pro.
