open a csv file in an active worksheet vba on mac - macos

Question

I am trying to rewrite my windows VBA code so i can use it on a Mac computer.
But somehow it is not possible to load the information into an active worksheet on mac.
Where MyFiles is the csv file opened by the code of http://www.rondebruin.nl/mac/mac015.html
.
I broke down the code a bit because i thought it didn't recognize the workbook. But i think the problem lies in the work book.
Set ws = ActiveWorkbook.Sheets("1. Pledges (ruw)")
MyFiles = MacScript(MyScript)
On Error GoTo 0
If MyFiles <> "" Then
With Application
.ScreenUpdating = False
.EnableEvents = False
End With
With ws.QueryTables.Add(Connection:="TEXT;" & MyScript, Destination:=ws.Range("A1"))
.TextFileParseType = xlDelimited
.TextFileCommaDelimiter = True
.Refresh
End With
If ws.Range("A2").Value = vbNullString Then
ws.rows("2").EntireRow.Delete
End If
With Application
.ScreenUpdating = True
.EnableEvents = True
End With
End If
End Sub
Some how it always crashes on the .refresh even if i use the code of robin the bruijn i can't use the querytables which work perfectly on windows.
Original windows code:
Dim ws As Worksheet, strFile As String
Set ws = ActiveWorkbook.Sheets("1. Pledges (ruw)") 'set to current worksheet name
strFile = Application.GetOpenFilename("Text Files (*.csv),*.csv", , "Please selec text file...")
With ws.QueryTables.Add(Connection:="TEXT;" & strFile, Destination:=ws.Range("A1"))
.TextFileParseType = xlDelimited
.TextFileCommaDelimiter = True
.RefreshOnFileOpen = False
.BackgroundQuery = True
.SaveData = True
End With
If ws.Range("A2").Value = vbNullString Then
ws.rows("2").EntireRow.Delete
End If
