Set standard F-keys for music apps on Mac

In a DAW, the F-row is a control surface: edit modes, tool selection, transport, and window layouts all sit on F1–F12. On a Mac they don't fire, because the top row is wired to brightness and volume by default. Turn on Use F1, F2, etc. keys as standard function keys and your F-row starts talking to Pro Tools, Logic, or Ableton instead of the system.

Why the F-row matters in a DAW

Producers and engineers lean on function keys because they keep both hands near the work. In Pro Tools, F1 through F4 switch the edit modes — Shuffle, Slip, Spot, and Grid — so you change how clips move without leaving the keyboard. Logic Pro and Ableton Live let you assign your own key commands, and the F-row is prime real estate for transport and tool bindings you hit hundreds of times a session.

Out of the box, macOS intercepts every one of those presses: F1 dims the display, F5 dims the keyboard backlight, F10 to F12 handle volume. The keystroke you meant for the DAW never arrives, and it feels like the app's shortcuts are broken when the setting is really upstream.

Turn on standard function keys

1. Open System Settings → Keyboard.
2. Click Keyboard Shortcuts….
3. Select Function Keys in the sidebar.
4. Turn on Use F1, F2, etc. keys as standard function keys.

The change is immediate and works the same on macOS 13 Ventura, 14 Sonoma, and 15 Sequoia. Open your session, tap F1, and Pro Tools flips into Shuffle mode; whatever you've mapped in Logic or Ableton now responds to a plain F-key press.

Volume and brightness move to Fn

You don't lose the media controls — the Fn key always does the opposite of the current setting, so with standard F-keys on, Fn+F11 and Fn+F12 still change system volume, and Fn+F1/F2 still adjust brightness. A couple of things worth checking once you switch:

• macOS reserves a few F-keys itself — F3 for Mission Control, F11 for Show Desktop. If a DAW binding on those keys doesn't respond, disable the matching system shortcut under Keyboard Shortcuts… so the key passes through.
• Many DAW commands live on the numeric keypad too; standard function keys don't affect those, so your keypad transport stays exactly as it was.

Set it from Terminal

One global default does it, handy for a dedicated studio Mac:

# F1-F12 send function keys to your DAW by default
defaults write NSGlobalDomain com.apple.keyboard.fnState -bool true

To go back to media keys as the default, write false or delete the key:

# Undo
defaults write NSGlobalDomain com.apple.keyboard.fnState -bool false
# or remove the key
defaults delete NSGlobalDomain com.apple.keyboard.fnState

The System Settings toggle applies right away; the Terminal route may need a log out and back in (or a restart) to take effect.

See what your F-keys are sending

If a binding still isn't landing, it helps to watch the keystrokes register. Open the Keyboard Viewer on Mac to confirm the top row is sending F-keys before you dig into your DAW's key commands.
