Let’s show you how to add functions keys on your MacBook laptop or Mac desktop.
In this video, I walk you through the steps to add function keys (F) to your Mac computer. First, open System Preferences and go to Keyboard. Click on Touch Bar shows and select F1, F2, etc. This enables your function keys above your keyboard. Additionally, you can do this by selecting the FN key on your keyboard.
