How to Upgrade Git on Mac OSX

Lets start by checking current version.

 
git --version

Install Homebrew if needed.

 
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

If Homebrew exists on your machine, update it.

 
brew update && brew upgrade

Install Git using Homebrew.

 
brew install git

Now restart the Terminal and check git version. You should see the updated version.

 
git --version

From now on, you can just update...

 
brew update && brew upgrade
