I just bought a new Mac with OS X Lion and I checked in the Terminal what version of git is installed by default. I got the answer

git --version
> git ver         


        

Answer 1

I used the following to upgrade git on mac.

hansi$ brew install git 

hansi$ git --version 
git version 2.19.0


hansi$ brew install git
Warning: git 2.25.1 is already installed, it's just not linked
You can use `brew link git` to link this version.

hansi$ brew link git 
Linking /usr/local/Cellar/git/2.25.1... 
Error: Could not symlink bin/git
Target /usr/local/bin/git
already exists. You may want to remove it:
  rm '/usr/local/bin/git'

To force the link and overwrite all conflicting files:
  brew link --overwrite git

To list all files that would be deleted:
  brew link --overwrite --dry-run git

hansi$ brew link --overwrite git 
Linking /usr/local/Cellar/git/2.25.1... 205 symlinks created


hansi$ git --version
git version 2.25.1
