SaveAs function works on Microsoft PC but not on MAC
<p>I have VBA code that controls the user from saving the file in any other format than .xls, .xlsm or .pdf. This is to prevent the stripping out of macros during the save process.</p>

<p>I have inserted a line to check if the operating system is OSx (... Like "<em>Mac</em>") which works in other macros but not this one. The process fails with "Can;t find the file object or library" with 'msoFileDialogSaveAs' highlighted.</p>

<p>Here is my code:</p>

<pre><code>    Option Explicit
    Option Compare Text

    Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean, _
        Cancel As Boolean)

      Dim fso As Object 'FileSystemObject
      Dim PdfSave As Boolean
      Dim SheetName As String
      If Not Application.OperatingSystem Like "*Mac*" Then
      SheetName = ActiveSheet.Name
      'Save-As action?
      If SaveAsUI Then
        Set fso = CreateObject("Scripting.FileSystemObject")
        'Abort excel's dialog
        Cancel = True
        'Create our own
        With Application.FileDialog(msoFileDialogSaveAs)
          'Select the XLSM filter by default
          .FilterIndex = 2
    Again:
          'Ok clicked?
          If .Show = -1 Then
            'Which extension should we save?
            Select Case fso.GetExtensionName(.SelectedItems(1))
              Case "xlsm"
                'Okay
              Case "xls"
                'Okay
              Case "pdf"
                PdfSave = True
                'Okay
              Case Else
                MsgBox "Invalid file type selected!" _
                  &amp; vbCr &amp; vbCr &amp; "Only the following file formats are   permitted:" _
                  &amp; vbCr &amp; "   1. Excel Macro-Enabled Workbook (*.xlsm)" _
                  &amp; vbCr &amp; "   2. Excel 97-2003 Workbook (*.xls)" _
                  &amp; vbCr &amp; "   3. PDF (*.pdf)" _
                  &amp; vbCr &amp; vbCr &amp; "Please try again." _
                  &amp; vbCr &amp; vbCr &amp; "NOTE: 'Excel 97-2003 Workbook (*.xls)' format should be used for" _
                  &amp; vbCr &amp; "backwards compatability only!", vbOKOnly + vbCritical
                GoTo Again
            End Select
            'Prevent that we call ourself
            Application.EnableEvents = False
            'Save the file
            If PdfSave = True Then
                ActiveSheet.ExportAsFixedFormat Type:=xlTypePDF,   Filename:=ActiveWorkbook.Path &amp; "\" &amp; SheetName &amp; ".pdf",  Quality:=xlQualityStandard, IncludeDocProperties:=True, IgnorePrintAreas:=False, OpenAfterPublish:=True
            Else
                ThisWorkbook.SaveAs .SelectedItems(1)
            End If
            Application.EnableEvents = True
          End If
        End With
      End If
      End If
    End Sub

<p>Can anyone suggest changes so that this code works for Office on both PC and MAC, or have different code that achieves the same thing.</p>

<p>Thanks</p>
