This is a very common issue on Mac and has a straightforward fix. On macOS, function keys (F1–F12) are mapped to system/media controls by default (brightness, volume, Mission Control, etc.), so F2 triggers "Decrease Brightness" instead of the Excel Edit function.
**Solution 1 — Use Fn + F2 (quickest fix):**
Hold the Fn key and press F2 at the same time. This tells macOS to pass the F2 key as a standard function key to Excel, triggering the Edit mode you want.
**Solution 2 — Change system settings so F-keys work as standard function keys:**
For MacBook Pro built-in keyboard:
- Go to System Settings > Keyboard
- Check the option: "Use F1, F2, etc. keys as standard function keys"
- After this, F2 in Excel will work directly without needing Fn
For your Logitech keyboard:
- The Logitech G Hub or Options+ software (depending on your model) may have its own F-key mode setting
- You may also check if your Logitech keyboard has an "Fn Lock" key or toggle (often Fn + Esc) to switch between media and standard function key modes
**Solution 3 — Excel-specific setting (alternative):**
- In Excel for Mac, you can also remap the Edit shortcut: Excel menu > Tools > Customize Keyboard and assign F2 there if Fn+F2 is inconvenient
Note: The macOS setting only affects the built-in keyboard. For the Logitech, you'll need to set the Fn Lock in the Logitech software or hardware key toggle.
Solution 1 (Fn + F2) will work immediately without any settings changes!
