Kodi 16.1 and IPTV Simple Client 2

Dear Kodi Forum,
I’ve always had Kodi in my PC and I have 2 different m3u playlists.
I found a way to add another IPTV Simple Client and everything was ok.
Now I’m trying to use it with my Macbook Pro, but it’s 2 days that I can’t find a way to add another Client.
Can anyone help me please?

Thanks a lot.
Best Regards.
