Facetime and "appropriate credentials"? HELP!
iMac 10.6.8, using Facetime regularly and successfully. Suddenly, it doesn't work. When I try to sign on with my Apple ID, I get the message "The registering device does not have appropriate credentials". I can't get past that message. I have tried ...
(1) Rebooting
(2) Resetting PRAM
(3) "killall imagent" in Terminal (which stops the Facetime daemon, and I can see in Activity Monitor that it has been stopped)
(4) logging out of Facetime on my other machines
These are all alleged to work. They don't for me. NOTHING works. My Apple login is fine, however (which is how I signed on to this forum!)
Facetime works fine for me on a MBP with Yosemite, which is sitting right next to my iMac. So I'm doing something right.
iMac, Mac OS X (10.6.8)
