I'm running Yosemite and iOS8. I started getting the stupid phone calls across all my devices, a true pain in the butt. I finally got that sorted out and turned off. I only want my phone ringing. Now, out of nowhere, I'm getting some, not all, iMessages sent to my phone and my computer at the same time. iMessage is set up on my computer, but only using my email address, not my phone number. one of my contacts, using my phone number, is showing up on my phone and iMac. is there a setting I'm missing? its really starting to piss me off.
