How to Fix Excel for Mac Function ScreenTips Not Showing All Arguments
Question details
The user needs to resolve an issue where Excel for Mac fails to display the complete syntax in function ScreenTips as formulas are typed.

- Product
- Microsoft Excel for Mac
- Device & OS
- macOS
- Scenario
- Typing a formula manually into a spreadsheet cell and relying on the pop-up ScreenTips for syntax and argument guidance.
- Observed behavior
- The in-cell ScreenTip only displays the first or currently expected argument for functions like SUMIF, hiding the rest, whereas the Formula Builder correctly shows all arguments.
Check if the function you are using actually requires multiple mandatory arguments, as Excel sometimes dynamically hides optional arguments until the required ones are entered.
Verify Your Excel Version and Update Software
Keeping your Office installation and macOS up to date can resolve known version-specific interface bugs causing incomplete ScreenTips.
Incomplete ScreenTips can often be tied to a specific build of Excel for Mac. Comparing your build with another installation where ScreenTips work properly can help identify the issue. Updating both Microsoft Office and macOS usually resolves these software glitches.
Click on 'Excel' in the top Mac menu bar and select 'About Microsoft Excel' to check your current version and build number.
Navigate to the 'Help' menu at the top of the screen and select 'Check for Updates' to install the latest patches from Microsoft.
Open macOS 'System Settings' (or System Preferences), go to 'General' > 'Software Update', and apply any pending system updates.
Restart your Mac to ensure all software updates take effect, then open Excel to check if the full ScreenTips are restored.

Use the Formula Builder as a Workaround
If the in-cell ScreenTip remains incomplete due to an unresolved Excel bug, use the Formula Builder to view all arguments clearly.
Try WPS Office for a Seamless Spreadsheet Experience
If Microsoft Excel for Mac continues to exhibit frustrating interface bugs like missing ScreenTips, consider switching to WPS Office. It provides a highly compatible, lightweight, and completely free alternative that displays full formula syntax clearly without glitches.

Frequently Asked Questions
Why does the SUM function ScreenTip only show one argument?
The SUM function technically requires only one mandatory argument; additional numbers or ranges are optional. Excel's ScreenTips are designed to adjust dynamically, displaying the arguments currently expected as information is entered.
Does the missing ScreenTip bug affect the calculation of my formulas?
No, this is purely a visual interface issue. Your formulas will still calculate correctly as long as you input the proper arguments, even if the in-cell ScreenTip does not display them all initially.
Where can I report this version-specific ScreenTip issue to Microsoft?
You can report the issue directly from Excel by clicking on the 'Help' menu and selecting 'Feedback'. Be sure to provide your specific Excel build number and your macOS version.
