Mac OS comes with a pre-installed Git. But this version is generally outdated. 

Solution 1:
To update it, we can go to Git website and download the latest version available for Mac and install it. But even if you type "git --version", you will not see the latest version you have installed. How come ?
When you installed Git from the Git Installer, it will install the git executable in a different place than your system's default one. The default is /usr/bin/git, and the new one is /usr/local/git/bin/git. Your shell however will not pick up the later one if its PATH isn't configured properly. How to configure the PATH ?
You can try adding the following to your ~/.bash_profile (if you use Bash, that is):
export PATH=/usr/local/git/bin:$PATH
Then, restart your shell and see if git now points to the new version. (Test with which git or git --version).

Solution 2: (from http://superuser.com/questions/776726/cant-use-homebrew-installed-git but solved my problem)

Step 1: Installing Xcode command line tools

I already had Xcode IDE installed. I launch Xcode and went to Xcode->Open Developper Tools->More Developpers Tools that led me to a website where i downloaded Xcode command line tools and installed it. And I tried the suggestion on ISS-SOA Github tutorial, the command 'xcode-select --install' which stopped with an error: Can't install the Software because it is not currently available from the Software Update server.Lucky then.


Step 2: Installing Homebrew

ruby -e "$(curl -fsSL XXXX)"
XXXX as an url that was the one on the Homebrew website.
