FaceTime calls wrong Person under YOSEMITE
Hello,
since I've installed the last Mac upgrade to Yosemite my FaceTime doesn't allow me to call anyone. I click on the right person but it calls always a different one than I wanted and so I can't call any of my contacts.
Can anyone give me a hint how to solve this issue?
Thanks a lot!
