I am using version 12.0.78517 on a Mac running OS X 10.12.4 and every time I connect to any computer, Teamviewer quits. I already uninstalled (including configuration) and reinstalled, but that made no difference.
Maybe try a pervious version?

Does the whole program close out on you or just the remote control window? I've been having an issue occasionally when I log into a PC I get kicked out of the session imediatly, but once I log back in I'm good to go.
The whole program appears to vanish and then relaunch. It's 100% reproducible. I can't log into any other machine from the afflicted machine.
Huh, that's a weird one. Unfortunately I don't have a Mac at my disposal to play with. If you are a paid user, I would try contacting support and see if they can help you out.
That worked. The current version of Teamviewer on the Mac is broken.
