- Product
- Excel for Mac
- Device & OS
- Mac
- Scenario
- Interacting with a Combo Box inserted from the Developer tab to select an item from a pre-defined list.
- Observed behavior
- The Combo Box appears visually pressed when clicked, but the drop-down list completely fails to open.
Before troubleshooting the form control, verify that the current workbook or worksheet is not protected, as this can block interaction with Developer controls.
Recreate the Combo Box and Verify Input Range
Recreating the specific control and double-checking its source properties often resolves localized control corruption.
Sometimes an individual form control becomes corrupted or loses its connection to the source data. Deleting the broken control and adding a fresh one is the most direct way to fix this issue.
Hold down the Control key, click the unresponsive Combo Box to select it, and press the Delete key.
Navigate to the Developer tab on the ribbon, click the Combo Box icon, and click anywhere on your sheet to draw the new control.
Right-click the newly created Combo Box, select Format Control from the context menu, navigate to the Control tab, and ensure the Input Range points to the correct cells containing your list data.
Test Combo Box Functionality in a New Workbook
Testing in a fresh environment determines if the issue is application-wide or restricted to a corrupted workbook.

Frequently Asked Questions
Why is my Developer tab missing in Excel for Mac?
By default, the Developer tab is hidden. To enable it, open Excel > Preferences > Ribbon & Toolbar, and check the box next to 'Developer' in the Main Tabs list.
How do I unprotect a workbook to allow combo box interactions?
Navigate to the Review tab on the ribbon and click 'Unprotect Sheet' or 'Unprotect Workbook'. If the document author set a password, you will be prompted to enter it before modifications are allowed.
Can a corrupted Excel file cause form controls to stop working?
Yes. If an underlying file structure becomes corrupted, visual elements like Combo Boxes may freeze or refuse to expand. If the control works perfectly in a new blank workbook but not the original, copying your data to a new workbook is usually the most effective fix.
