Mac Only Facetimes Emails
My MacBook Pro (2012, 13 inch) will only Facetime contacts with emails. It won't Facetime any contacts that only have numbers.
This only started after I updated my computer to OS X El Capitan. It may be unrelated, but I've tried restarting my computer and my phone. I've signed out of iMessage and Facetime and restarted both. I've checked that my Date & Time settings were set automatically and that the right location is selected. Facetime works on my phone, but the connection doesn't work as well as on my computer when it is plugged into an ethernet.
Any help is appreciated! Thanks
MacBook Pro, OS X El Capitan (10.11.4)
