Still signed in to Messages & FaceTime after sign out & reboot
Hi,
It seems I can't sign out of Messages or FaceTime.
Steps to reproduce:
1. Open Messages app preferences and sign out of iMessage account.
2. Open FaceTime app preferences and sign out of the Apple ID account.
3. Reboot the computer.
At this stage, when I re-open either the Messages or FaceTime app and look at the preferences, my Apple ID is signed in again.
How can I sign out of Messages and FaceTime for good?
This is part of a larger problem: I'm experiencing issues with Messages syncing on OS X Yosemite. It was working fine for a while, then stopped.
Everything's still working fine on my iPhone, it's the syncing to OS X that's broken.
I've been searching for solutions to this for a while. I am able to link OS X to my iPhone successfully in Safe Mode as well as signed in to a different account on the same machine. (See Mac Pro - Yosemite - iMessage won't connect.)
In all my testing I noticed something strange with my credentials in the FaceTime & Messages apps: when I sign out of either of them, then reboot, I'm signed in again.
Other observations:
Launching the Messages app always takes 5~6 seconds, and the beachball appears for about 1~2 seconds at the end.
If I sign out of the iMessage account, quit the Messages app, then re-launch it (without rebooting the computer) and attempt to sign in, it never finishes. The spinner on the sign in dialog spins for eternity. I will eventually kill the app, and after re-launching it, I'm signed in again.
