XL pour MAC Outil de surveillance de ping Excel Mac OS

Bonjour,
je souhaite surveiller plusieurs pings sur Excel. J'ai trouvé un auto fonctionnant sur windows mais je suis sur Mac OS.
Voici le liens de la video:
J'ai repris ce code:

Function Ping(strip)
Dim objshell, boolcode
Set objshell = CreateObject("Wscript.Shell")
boolcode = objshell.Run("ping -n 1 -w 1000 " & strip, 0, True)
If boolcode = 0 Then
Ping = True
Else
Ping = False
End If
End Function

Sub PingSystem()
Dim strip As String
Do Until ActiveSheet.Range("F1").Value = "STOP"
ActiveSheet.Range("F1").Value = "TESTING"
For introw = 2 To ActiveSheet.Cells(65536, 2).End(xlUp).Row
strip = ActiveSheet.Cells(introw, 2).Value
If Ping(strip) = True Then
ActiveSheet.Cells(introw, 3).Interior.ColorIndex = 0
ActiveSheet.Cells(introw, 3).Font.Color = RGB(0, 0, 0)
ActiveSheet.Cells(introw, 3).Value = "Online"
Application.Wait (Now + TimeValue("0:00:01"))
ActiveSheet.Cells(introw, 3).Font.Color = RGB(0, 200, 0)
Else
ActiveSheet.Cells(introw, 3).Interior.ColorIndex = 0
ActiveSheet.Cells(introw, 3).Font.Color = RGB(200, 0, 0)
ActiveSheet.Cells(introw, 3).Value = "Offline"
Application.Wait (Now + TimeValue("0:00:01"))
ActiveSheet.Cells(introw, 3).Interior.ColorIndex = 6
End If
If ActiveSheet.Range("F1").Value = "STOP" Then
Exit For
End If
Next
Loop
ActiveSheet.Range("F1").Value = "IDLE"
End Sub

Sub stop_ping()
ActiveSheet.Range("F1").Value = "STOP"
End Sub

La ligne : Set objshell = CreateObject("Wscript.Shell") est celle qui me pose problème pour le moment.

Merci pour votre aide.
