After upgrading one of the three computers in my office from Mac OS X 10.9 to Mac OS 10.10 (Yosemite) I thought to myself – wow – I like the option to answer my phone using my MacBook Pro.
A few days later – when I had the other computers upgraded as well – any time I got a phone call – my office sounded like a call center (2 bluetooth cordless phones, 3 computers, and the actual iPhone itself were all ringing at the same time.
Thankfully – you can easily turn off this feature in the FaceTime app by simply unchecking one thing in the FaceTime preferences (see screenshot). So if you are like me – and do not need this or prefer to not use it – the fix is easy!
