How to Fix Excel Macro Warnings on Mac Office 2011
Question details
The user needs to eliminate persistent Visual Basic macro warnings and page layout margin issues that occur when opening Excel, despite having no active user-created macros.

- Product
- Excel for Mac 2011
- Device & OS
- Mac
- Scenario
- Opening the Excel application or individual workbook files on a Mac.
- Observed behavior
- Excel triggers a Visual Basic macro warning on startup and opens workbooks in Page Layout view with incorrect margins, caused by an unwanted background add-in.
Ensure that Microsoft Excel is completely closed before navigating to and modifying the Office Startup folder to prevent file locks or application crashes.
Remove Unwanted Add-ins from the Excel Startup Folder
Deleting third-party add-ins or templates (like the Dymo Label Manager add-in) from the Excel Startup folder stops the automatic macro triggers and restores correct layout margins.
Third-party applications, such as Dymo Label Manager updates, often install hidden add-in files (e.g., DYMOExcelAddin.xlt) into the Excel Startup folder. Excel attempts to load these automatically on launch, which triggers the macro security warning and can disrupt default page layouts.
Right-click the Excel icon in your Mac Dock and select 'Quit', or press Cmd + Q while the application is active.
Open Finder and go to Applications > Microsoft Office 2011 > Office > Startup > Excel.
Look for unrecognized .xlt or .xla files. In many instances, this will be named 'DYMOExcelAddin.xlt'.
Drag the suspicious add-in file to the Trash. Empty the Trash to ensure it is permanently removed from the system.
Launch Excel again. The Visual Basic macro warning should no longer appear, and your page layouts will return to normal formatting.

Frequently Asked Questions
Why am I getting a macro warning if I haven't written any macros?
Third-party software installed on your Mac can silently add template (.xlt) or add-in files containing macros to Excel's Startup folder. Excel loads these automatically, triggering the security warning even if you didn't create the files yourself.
Can I just disable macro warnings in Excel settings?
While you can lower your macro security settings in the Trust Center to stop the warnings, this is highly discouraged. Doing so leaves your Mac vulnerable to potentially malicious scripts. Removing the problematic add-in is the safest and most effective solution.
Where is the Excel 2011 Startup folder located on a Mac?
By default, the Startup folder for Microsoft Office 2011 is located at Applications > Microsoft Office 2011 > Office > Startup > Excel. Any supported file placed within this directory loads automatically when the Excel application boots.
