Excel for Mac- Converting tested windows Excel macro to Mac - excel

Question

I am a newbie to macros but I was able to find and modify a macro to works for what I needed. The macro is for a Form that once filled out the user will push the "Save and email" button and the following will happen:
save location window will open, the file will be converted and saved as .pdf (the file name is predetermined based on cells information)
the active sheet will be converted to .pdf it will be attached to an email.
I was very proud of my achievement until I tested it on my Mac and realized that it will not work. Now, I am faced with a challenge of converting the macro from Windows to Mac in order for the keep the functionality of the Form.
Below is the tested code on a Windows Excel:
Sub Button9_Click()
Dim xSht As Worksheet
Dim xFileDlg As FileDialog
Dim xFolder As String
Dim xYesorNo As Integer
Dim xOutlookObj As Object, signature As String
Dim xEmailObj As Object
Dim xUsedRng As Range
Set xSht = ActiveSheet
Set xFileDlg = Application.FileDialog(msoFileDialogFolderPicker)
If xFileDlg.Show = True Then
xFolder = xFileDlg.SelectedItems(1)
Else
MsgBox "You must specify a folder to save the PDF into." & vbCrLf & vbCrLf & "Press OK to exit this macro.", vbCritical, "Must Specify Destination Folder"
Exit Sub
End If
xFolder = xFolder + "\" + xSht.Range("G3").Text + ".pdf"
'Check if file already exist
If Len(Dir(xFolder)) > 0 Then
xYesorNo = MsgBox(xFolder & " already exists." & vbCrLf & vbCrLf & "Do you want to overwrite it?", _
vbYesNo + vbQuestion, "File Exists")
On Error Resume Next
If xYesorNo = vbYes Then
Kill xFolder
Else
MsgBox "if you don't overwrite the existing PDF, I can't continue." _
& vbCrLf & vbCrLf & "Press OK to exit this macro.", vbCritical, "Exiting Macro"
Exit Sub
End If
If Err.Number <> 0 Then
MsgBox "Unable to delete existing file. Please make sure the file is not open or write protected." _
& vbCrLf & vbCrLf & "Press OK to exit this macro.", vbCritical, "Unable to Delete File"
Exit Sub
End If
End If
Set xUsedRng = xSht.UsedRange
If Application.WorksheetFunction.CountA(xUsedRng.Cells) <> 0 Then
'Save as PDF file
xSht.ExportAsFixedFormat Type:=xlTypePDF, Filename:=xFolder, Quality:=xlQualityStandard
'Create Outlook email
Set xOutlookObj = CreateObject("Outlook.Application")
Set xEmailObj = xOutlookObj.CreateItem(0)
With xEmailObj
.Display
.Subject = ActiveWorkbook.Sheets("FORM").Range("G3")
.To = "name"
.CC = " "
.body = "Hi ..," & vbLf & vbLf _
& "The Parts Request Form is attached in PDF format." & vbLf & vbLf _
& "Regards," & vbLf & vbLf _
& Application.UserName & vbLf & vbLf _
& "..." & vbLf _
& "..., ..." & vbLf _
& "..." & vbLf _
.Attachments.Add xFolder
If DisplayEmail = False Then
'.Send
End If
End With
Else
MsgBox "The active worksheet cannot be blank"
Exit Sub
End If
End Sub
