I'm at the point where I've totally confused myself trying to figure this out so forgive me if there is an easy and obvious fix to this. I have an iPhone 6 and an iMac both setup on the same Apple ID. I get iMessages/SMS on both devices and also I can take calls on either. The problem is that when I text my girlfriend on her 3GS she sometimes receives the text from my email address associated with my Apple ID and sometimes from my phone number. This creates two separate entries in the messages app which are both from me. Have I set this up wrong somewhere and more importantly is it possible to fix this annoyance?
