Question details

The user needs to troubleshoot AutoRecover and invalid procedure call errors occurring in an Excel VBA workbook after moving it from a Windows PC to a Mac.

Product: Microsoft Excel
Device & OS: Windows and macOS
Scenario: Migrating a functional Excel workbook containing VBA macros from a Windows environment to macOS.
Observed behavior: The workbook triggers AutoRecover loops and invalid procedure call errors on macOS due to incompatible Windows-specific VBA code, such as the MacrosExist function.

Before you start

Before modifying any VBA code, ensure you save a backup copy of your original workbook to prevent accidental data loss while debugging cross-platform compatibility issues.

Solution 1Recommended

Debug and Modify Windows-Specific VBA Code

Use the Mac VBA debugger to locate and replace Windows-specific functions that trigger invalid procedure calls.

Many VBA scripts written on Windows utilize features that are unavailable on macOS, such as ActiveX controls, Windows API calls, or specific file path structures (like the Scripting.Dictionary or FileSystemObject). Functions like MacrosExist often rely on these Windows-only components, causing the code to fail upon execution on a Mac.

Open the VBA Editor on Mac

Open the problematic workbook in Excel for Mac and press 'Option + F11' to open the Visual Basic Editor.

Step through the code

Go to the 'Run' menu and select 'Step Into' (or press 'Command + Shift + I') to execute your VBA macro line by line.

Identify the failing line

Continue stepping through until the 'Invalid Procedure Call' error appears. The highlighted line is the source of the compatibility issue.

Replace incompatible code

Rewrite the highlighted line using Mac-compatible equivalents, such as replacing Windows directory separators (\) with Mac separators (/), or using MacScript/AppleScript for system-level commands.

ActiveX Limitations: ActiveX controls are entirely unsupported on macOS. If your workbook relies on them, you must replace them with standard Form Controls.

Solution 2

Create a Sanitized Workbook for Community Support

If you cannot pinpoint the error, prepare a sanitized version of your workbook to share with developers or support forums for detailed troubleshooting.

Frequently Asked Questions

Why do my Excel VBA macros work on Windows but not on Mac?

Mac and Windows environments have different underlying file systems and system architectures. VBA features that rely on Windows-specific components like ActiveX controls, the Scripting Runtime library, or Windows API calls will not function on macOS.

How do I fix the 'Invalid Procedure Call' error in Mac Excel?

This error typically occurs when VBA tries to execute a command that doesn't exist on Mac. You must open the VBA Editor, step through the code to find the exact line causing the crash, and replace it with a Mac-compatible function or AppleScript alternative.

Can I use ActiveX controls in Excel for Mac?

No, ActiveX is a proprietary Microsoft Windows technology and is completely unsupported on macOS. You will need to replace any ActiveX buttons or dropdowns with standard Excel Form Controls.

What does a sanitized workbook mean?

A sanitized workbook is a copy of your Excel file that has had all confidential, personal, or proprietary data removed, while keeping the structural elements and VBA macros intact. This allows developers to safely test and debug your code.
