SOMEBODY PLEASE HELP! I had purchased a mac mini for my parents and my grandparents in Florida. I live in NY and I communicate with them frequently. When they have technical computer questions we log onto ichat and start screen sharing. I simply take control of their screen and go from there. This worked great until my grandparents switched internet providers from Comcast to AT&T... I'm on Verizon. Has anyone run into a problem with screen sharing via these two internet providers? My screen sharing works fine with Bellsouth.net, Optimum Online, Verizon and Comcast, but WILL NOT work with AT&T, does anyone know a solution, other than having them switch from AT&T to comcast??
Thanks
