He codificado la siguiente función. Sin embargo, no puedo hacerlo funcionar en la oficina Mac. No estoy seguro del procedimiento para encontrar el equivalente de EXP_PDF.DLL mac

Function Create_PDF(Myvar As Object, FixedFilePathName As String, _                    
OverwriteIfFileExist As Boolean, OpenPDFAfterPublish As Boolean) As String    

Dim FileFormatstr As String    
Dim FName As Variant

'Test If the Microsoft Add-in is installed    
If Dir(Environ("commonprogramfiles") & "\Microsoft Shared\OFFICE" _& Format(Val(Application.Version), "00") & "\EXP_PDF.DLL") <> "" Then
        If FixedFilePathName = "" Then            
           'Open the GetSaveAsFilename dialog to enter a file name for the pdf            
           FileFormatstr = "PDF Files (*.pdf), *.pdf"            
           FName = Application.GetSaveAsFilename("", filefilter:=FileFormatstr, _                                                                                       Title:="Create PDF")
            'If you cancel this dialog Exit the function            
            If FName = False Then Exit Function        
         Else            
            FName = FixedFilePathName        
        End If
        'If OverwriteIfFileExist = False we test if the PDF        
         'already exist in the folder and Exit the function if that is True        
        If OverwriteIfFileExist = False Then            
            If Dir(FName) <> "" Then Exit Function        
        End If

       'Now the file name is correct we Publish to PDF        
       On Error Resume Next        
       Myvar.ExportAsFixedFormat _                
                Type:=xlTypePDF, _                
                FileName:=FName, _                
                Quality:=xlQualityStandard, _                
                IncludeDocProperties:=True, _                
                IgnorePrintAreas:=False, _                
                OpenAfterPublish:=OpenPDFAfterPublish        
        On Error GoTo 0

        'If Publish is Ok the function will return the file name        
         If Dir(FName) <> "" Then Create_PDF = FName    

End If
End Function
