Installing a NerdFont on MacOS
Installing a NerdFont on MacOS is particularly easy because NerdFonts are available via Homebrew.
To install the Hack NerdFont, for example, run these commands:
brew tap homebrew/cask-fonts
brew install --cask font-hack-nerd-font
Then go to your terminal's preferences and set the font to the newly installed NerdFont. If you're using iTerm2, this is located at:
iTerm2 -> Preferences -> Profiles tab -> Text tab -> Font dropdown -> Hack Nerd Font Mono
