I'm getting the error "Object variable or With block variable not set" when I try to run the following macro on Word 2016 on a Mac:

Sub MarkupToggle()
With ActiveWindow.View
.ShowRevisionsAndComments = Not .ShowRevisionsAndComments
.RevisionsView = wdRevisionsViewFinal
End With
End Sub

How can I diagnose this error?

You can tell us which line is highlighted in Yellow when you choose debug.

The highlighted line is

With ActiveWindow.View

Which would indicate that the Mac version of Word 2016 doesn't have either an ActiveWindow or if it does, the ActiveWindow doesn't have a View property.

Have you tried recording a macro to see what is created when you toggle the revisions visibility or set the revisions to display as final?

Moving the Sub from Normal's "This Document" to Normal's "New Macros" fixed the problem. I guess it's because "This Document" confuses the ActiveWindow.View property.
