Need to upgrade/update git to the latest version on your Mac? The following should do the trick:
First, if you don’t already have homebrew installed, install homebrew:
$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Then update/upgrade brew:
$ brew update
$ brew upgrade
Install the latest version of git with homebrew:
$ brew install git
Now, make sure to close your terminal app. This is key because if you don’t close your terminal app and then re-open it, your terminal will not recognize the latest version installed via homebrew.
In a new terminal window, run the following to confirm you are now running the latest version of git:
$ git --version
