How to Fix Space Bar Selecting Cells Instead of Typing in Excel on Mac
Question details
The user needs to stop the Space bar from selecting cells or windows instead of inserting a space character when working in Excel on a Mac.

- Product
- Microsoft Excel
- Device & OS
- macOS
- Scenario
- Typing data into a spreadsheet cell and using the Space bar to insert a space.
- Observed behavior
- Pressing the Space bar highlights or selects cells and windows instead of typing a space character.
Ensure you have saved any open workbooks in Excel before modifying your Mac system settings, as a system restart may be required to apply changes.
Disable Full Keyboard Access in Mac Settings
Turning off Full Keyboard Access prevents the macOS system from intercepting the Space bar for navigation purposes.
The macOS Full Keyboard Access feature is designed to let users navigate the interface using only the keyboard. When enabled, the Space bar acts as an activation key (like a mouse click) rather than a typing key, which interrupts standard typing in applications like Excel.
Click the Apple menu in the top-left corner of your screen and select 'System Settings' (or 'System Preferences' on older macOS versions).
Scroll down the left sidebar and click on 'Accessibility'.
In the Accessibility menu, find and click on 'Keyboard', then go to the 'Navigation' section.
Locate the 'Full Keyboard Access' toggle and switch it off. Return to Excel to test if the Space bar now functions correctly.

Remove the Space Bar Assignment for Keyboard Access
If you need to keep Full Keyboard Access enabled for other tasks, you can specifically unbind the Space bar from the selection command.
Update macOS and Restart
If adjusting the accessibility settings does not resolve the issue, a temporary software glitch may be responsible. Updating your system and restarting can clear these bugs.

Frequently Asked Questions
Why does my Space bar act like the Enter key on my Mac?
This occurs when 'Full Keyboard Access' is enabled in your Mac's Accessibility settings. This feature repurposes the Space bar to select or activate highlighted interface elements, treating it as a navigation click instead of inserting a space character.
Does this Space bar issue only affect Microsoft Excel?
No. While it is commonly noticed in Excel when users try to add spaces between words or numbers in cells, this macOS setting affects all applications by prioritizing system UI navigation over standard text input.
Can I use Full Keyboard Access without the Space bar glitch?
Yes. By navigating to the Full Keyboard Access options in your Mac's Accessibility settings, you can clear the specific shortcut assigned to the Space bar while leaving the rest of the accessibility navigation features active.
Will uninstalling and reinstalling Excel fix this issue?
Uninstalling Excel will not resolve this problem because the behavior is fundamentally controlled by macOS system accessibility settings, not the Microsoft Office application itself.
