It will automatically install Developer tools if not available in your system.
When installation is done, run the two commands from the "==> Next steps:" section found in output of your terminal
echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/lana/.zprofile
eval "$(/opt/homebrew/bin/brew shellenv)"

Mac already comes with git installed
git --version
=> git version 2.30.1 (Apple Git-130)
Get the latest version of git by installing it with Homebrew

brew install git

git --version
=> git version 2.36.1
Double-check your git global configurations
git config --global --list
If your user.email and user.name are not set, run the following to set your git global configurations
git config --global user.email "<youremail>"
git config --global user.name "<yourname>"

Then Change the default shell in Terminal on Mac or run the following
