MAC VBA Issue whwn I try to open xml file

[gio123bg]

Hello All,
I need to use a macro in Mac environment but when I try to open the xlm file in Mac I can't find the possible selection for xml file type.
More exactly this is my check.

If Not Application.OperatingSystem Like "*Mac*" Then
' Is Windows.

FileToOpen = Application.GetOpenFilename _
(Title:="Please choose a file to import", _
FileFilter:="XML files of the form *.xml (*.xml),")


Else
' Is Mac

FileToOpen = Select_File_Or_Files_Mac()

End If

Function Select_File_Or_Files_Mac() As String

Dim MyPath As String
Dim MyScript As String
Dim MyFiles As String
Dim MySplit As Variant
Dim N As Long
Dim Fname As String
Dim mybook As Workbook

On Error Resume Next
MyPath = MacScript("return (path to documents folder) as String")

MyScript = _
"set applescript's text item delimiters to "","" " & vbNewLine & _
"set theFiles to (choose file of type " & _
" {""com.microsoft.Excel.xls""} " & _
"with prompt ""Please select a file or files"" default location alias """ & _
MyPath & """ multiple selections allowed true) as string" & vbNewLine & _
"set applescript's text item delimiters to """" " & vbNewLine & _
"return theFiles"

MyFiles = MacScript(MyScript)
On Error GoTo 0

If MyFiles <> "" Then
With Application
.ScreenUpdating = False
.EnableEvents = False
End With

MySplit = Split(MyFiles, ",")
For N = LBound(MySplit) To UBound(MySplit)

' Get the file name only and test to see if it is open.
Fname = Right(MySplit(N), Len(MySplit(N)) - InStrRev(MySplit(N), Application.PathSeparator, , 1))
If bIsBookOpen(Fname) = False Then

Set mybook = Nothing
On Error Resume Next
Set mybook = Workbooks.Open(MySplit(N))
On Error GoTo 0

If Not mybook Is Nothing Then
MsgBox "You open this file : " & MySplit(N) & vbNewLine & _
"And after you press OK it will be closed" & vbNewLine & _
"without saving, replace this line with your own code."
mybook.Close SaveChanges:=False
End If
Else
MsgBox "We skipped this file : " & MySplit(N) & " because it Is already open."
End If
Next N
With Application
.ScreenUpdating = True
.EnableEvents = True
End With
End If
Select_File_Or_Files_Mac = mybook
End Function

Thanks in advance for your kind support.
