Hello and welcome to this macOS cheatsheet.

The goal is to gather here all known issues and tips with the macOS setup.

Issues

Brew HEAD not linked to origin/master ?

If you get one of the following error while installing a binary

bash

~ % brew install git
fatal: Could not resolve HEAD to a revision
No available formula or cask for the name "git"

This should help

bash

git -C $(brew --repository homebrew/core) checkout master

If you get a Homebrew error Permission denied @ apply2files with "docker" in the path that follows,

run

mkdir -p /Applications/Docker.app/Contents/Resources/cli-plugins

and then rerun brew cleanup.
