Hi,
this is an old topic but I wanted to ask if, in the meantime, anyone has figured out a way to connect X-Plane (12) running on a Mac to an ATC2Pilot installation on a Windows PC. As far as I could figure, the missing link is XPUIPC not being available on Mac but maybe there are new developments or alternatives that I don't know yet (I'm a very new to the world of flight simulation, I quite versed in dealing with the technical aspects though so happy to go through some setup-struggles if that is necessary to make it work)
Cheers!
