Download at iterm2.com/downloads
Set out Status Bar Component Menu
iTerm2 > Preferences > Profiles > Session > Status bar enabled > Configure Status Bar

2. Homebrew
Download at brew.sh
or run this in terminal
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
It will automatically install Developer tools if not available in your system.
When installation is done, run the two commands from the "==> Next steps:" section found in output of your terminal
echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/lana/.zprofile
eval "$(/opt/homebrew/bin/brew shellenv)"
3. Git
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>"

4. zsh and ohmyzsh
zsh
Mac already comes with zsh installed and set as a default
Check what shell is set as a default

=> /bin/zsh
If the return is not the above, install zsh with Homebrew
brew install zsh
zsh --version
=> zsh 5.8.1 (x86_64-apple-darwin21.0)
Then Change the default shell in Terminal on Mac or run the following
chsh -s $(which zsh)
ohmyzsh
Install ohmyzsh, the following will run the install script from Github ohmyzsh's install.sh
