Sometimes, git autocomplete on mac does not work as expected. This guide assumes you have homebrew installed. To get git to do autocompletions when you hit <tab> run:
brew install git bash-completion
Then, edit your ~/.bash_profile and add:
if [ -f $(brew --prefix)/etc/bash_completion ]; then . $(brew --prefix)/etc/bash_completion fi
Finally, run:
source ~/.bash_profile
If that still doesn’t work, you might have to run brew install git to get git up to date on your system.
