Apple MAC Operating (file dialog object) code advice

[VBA learner ITG]

Good morning all,

I hope you are having a great day. I hope you can help as I am now stuck on the code as I have tried numerous iterations and I can seem to resolve the "Compile Error" message on file dialog object.

I am sure I am missing something, but I can't see the forrest through the trees.

Any advice appreciated.

Sub CompareWorkbooksAndHighlightChangesV4()
    Dim wb1 As Workbook, wb2 As Workbook
    Dim ws1 As Worksheet, ws2 As Worksheet
    Dim cell1 As Range, cell2 As Range
    Dim changes As Worksheet
    Dim lastRow As Long
    Dim file1Path As String, file2Path As String
    
    ' Create a file dialog object
    Dim dlg As FileDialog
    Set dlg = Application.FileDialog(msoFileDialogFilePicker)
    
    ' Set the filter to all files
    dlg.Filter = "*.xlsx"
    
    ' Show the file dialog box
    dlg.Show
    
    ' If the user selected a file, get the path
    If dlg.SelectedItems.Count > 0 Then
        file1Path = dlg.SelectedItems(1)
    End If
    
    ' If the user did not select a file, exit the sub
    If file1Path = vbNullString Then Exit Sub
    
    ' Prompt the user to select the second workbook
    dlg.Filter = "*.xlsx"
    dlg.Show
    
    ' If the user selected a file, get the path
    If dlg.SelectedItems.Count > 0 Then
        file2Path = dlg.SelectedItems(1)
    End If
    
    ' If the user did not select a file, exit the sub
    If file2Path = vbNullString Then Exit Sub
    
    ' Set the first workbook and worksheet
    Set wb1 = Workbooks.Open(file1Path)
    Set ws1 = wb1.Sheets("Sheet1") ' Update the sheet name if necessary
    
    ' Set the second workbook and worksheet
    Set wb2 = Workbooks.Open(file2Path)
    Set ws2 = wb2.Sheets("Sheet1") ' Update the sheet name if necessary
    
    ' Create a new worksheet to store the list of changes
    Set changes = ThisWorkbook.Worksheets.Add(After:=ThisWorkbook.Sheets(ThisWorkbook.Sheets.Count))
    changes.Name = "Changes"
    
    ' Set headers in the changes worksheet
    changes.Cells(1, 1).Value = "Worksheet"
    changes.Cells(1, 2).Value = "Cell Address"
    changes.Cells(1, 3).Value = "Value in Workbook 1"
    changes.Cells(1, 4).Value = "Value in Workbook 2"
    
    ' Loop through each cell in the first worksheet and compare with the second worksheet
    lastRow = 2 ' Start from row 2 in the changes worksheet
    For Each cell1 In ws1.UsedRange
        Set cell2 = ws2.Range(cell1.Address)
        If cell1.Value <> cell2.Value Then
            cell2.Interior.ColorIndex = 3 ' Highlight in red color
            
            ' Add the change details to the changes worksheet
            changes.Cells(lastRow, 1).Value = ws1.Name ' Worksheet name
            changes.Cells(lastRow, 2).Value = cell1.Address ' Cell address
            changes.Cells(lastRow, 3).Value = cell1.Value ' Value in Workbook 1
            changes.Cells(lastRow, 4).Value = cell2.Value ' Value in Workbook 2
            
            lastRow = lastRow + 1
        End If
    Next cell1
    
    ' Save and close the workbooks
    wb2.Save
    wb2.Close
    wb1.Close
End Sub
