How to Fix Alt Key Not Working for Excel Shortcuts on Mac
Question details
The user is unable to trigger ribbon commands using Windows-style Alt-key shortcuts (such as Alt+H+B+A) in Microsoft Excel on a Mac.

- Product
- Excel for Mac
- Device & OS
- Mac
- Scenario
- Attempting to use familiar Windows Excel keyboard shortcuts via the Alt key to format cells or access ribbon commands on a Mac computer.
- Observed behavior
- The Alt key shortcuts do not function. The keystrokes either do nothing or type special characters, failing to navigate the ribbon.
Confirm that your Mac keyboard is functioning properly. Note that this issue is due to architectural differences between macOS and Windows, not a hardware failure or a broken external keyboard.
Assign Custom Keyboard Shortcuts in Excel for Mac
Since Windows Alt-key ribbon shortcuts aren't natively supported on macOS, creating custom shortcuts via Excel preferences is the most reliable workaround.
Excel for Mac does not use the Alt key to activate ribbon keytips like the Windows version does. Instead, macOS relies on its own shortcut system. To regain quick access to frequently used commands like 'All Borders', you must manually assign a custom keyboard combination.
Launch Excel for Mac. Go to the top Apple menu bar, click on 'Tools', and select 'Customize Keyboard' from the dropdown list.
In the 'Categories' list on the left, select the appropriate ribbon tab (for example, 'Home' or 'Format'). Then, find the specific action in the 'Commands' list, such as 'All Borders'.
Click inside the 'Press new keyboard shortcut' text box. Press the exact key combination you want to use (e.g., Command + Option + B). Ensure the combination isn't already assigned to another critical function.
Click the 'Add' button to assign the shortcut, then click 'OK' to close the dialog box. Your new shortcut is now ready to use in your spreadsheets.

Frequently Asked Questions
Why do standard Windows Excel shortcuts not work on my Mac?
macOS and Windows have entirely different operating system architectures and interface guidelines. Because of this platform difference, Excel for Mac does not natively support the Alt-key ribbon navigation shortcuts (like Alt+H) used in the Windows version.
Can I use an external Windows keyboard to fix the Alt key shortcuts on Mac?
No. Plugging in an external Windows keyboard will not enable Alt-key ribbon shortcuts. The limitation is written into the Excel for Mac software itself, meaning it is a platform difference rather than a hardware issue.
How do I apply 'All Borders' without the Windows Alt+H+B+A shortcut on Mac?
To quickly apply borders on a Mac, you can either manually click the Borders icon located on the Home tab of the ribbon, or you can create a custom keyboard shortcut for 'All Borders' via the Tools > Customize Keyboard menu.
Is Microsoft planning to add Alt-key shortcuts to Excel for Mac?
While Microsoft has tested bringing some Windows-style ribbon shortcuts to Mac via their Office Insider beta program, these features are not fully implemented or guaranteed in the standard, stable release of Excel for Mac.
