How to use the function keys on your Mac

The top row of keys on your Apple keyboard can control built-in Mac features or be used as standard function keys.

Use the keys to control features

By default, the top row of keys on your Apple keyboard control many different features on your Mac. For example, pressing the keys with speaker icons will adjust the volume.

Use the keys as standard function keys

Press and hold the Function (Fn)/Globe key  while pressing a function key. For example, pressing both Fn and F12 (speaker icon) will perform the action assigned to the F12 key instead of raising the volume of your speakers.1 If your keyboard doesn't have an Fn key, try pressing and holding the Control key when pressing a function key.


Change the default behaviour of the keys

If you want to change the top row of keys to work as standard function keys without holding the Fn key, follow these steps, depending on the version of macOS you're using:

macOS Ventura

  1. Choose Apple menu  > System Settings.
  2. Click Keyboard in the sidebar.
  3. Click the Keyboard Shortcuts button on the right.
  4. Click Function Keys in the sidebar.
  5. Turn on "Use F1, F2, etc. keys as standard function keys".2

Earlier macOS versions

  1. Choose Apple menu  > System Preferences.
  2. Click Keyboard.
  3. Select "Use F1, F2, etc. keys as standard function keys".2

 

 


1. Standard function keys work differently depending on the app and the keyboard shortcuts you've set up. Some apps have their own keyboard shortcut settings you can customise.

2. If you can't see this setting, you may be using a keyboard not made by Apple, and you may need a third-party keyboard utility to change the keyboard functions. Check with your keyboard manufacturer for more information.
