- Product
- Microsoft Excel for Mac
- Device & OS
- macOS
- Scenario
- Attempting to quickly calculate the average of a selected data range using the AutoSum tool on the ribbon.
- Observed behavior
- The Average option is missing from the AutoSum menu. Changing to Normal worksheet view does not bring the function back.
Ensure you have saved your current workbook locally or to the cloud to prevent data loss before restarting your Mac or updating the Excel application.
Restart Your Mac and Verify Software Versions
A system restart often clears temporary interface glitches that cause menu items to disappear, while checking versions ensures you are not dealing with a known bug in an outdated release.
Software updates frequently contain patches for UI bugs, including missing ribbon buttons or drop-down menu options in Microsoft Office.
Click the Apple menu in the top-left corner of your screen and select 'Restart...'. Once your Mac reboots, open Excel to see if the AutoSum options have returned.
If the issue persists, click the Apple menu and select 'About This Mac' to confirm your exact macOS version.
Open Excel, click 'Excel' in the top menu bar, and select 'About Microsoft Excel'. Note the version number and check for any pending Microsoft AutoUpdate installations.

Review Worksheet Views and Data Layout
Ensure that your current worksheet layout is not restricting data selection, though standard view settings do not inherently disable functions.

Frequently Asked Questions
Why are options missing from my AutoSum menu in Excel for Mac?
Missing drop-down options are typically caused by temporary software UI glitches, corrupted ribbon customizations, or using an outdated version of Excel. Restarting the application or your Mac is the best first step.
Does changing the worksheet view hide the AutoSum Average function?
No. The view shortcuts on the status bar (such as Normal view) only affect how the worksheet is visually displayed on your screen. They do not hide function menus or prevent you from editing cells.
How do I manually calculate the average if the AutoSum button is missing?
You can manually type the formula into any cell. Select an empty cell and type =AVERAGE(A1:A10), replacing 'A1:A10' with the actual range of your data, then press Return.
