I installed TeamViewer Host on my Mac running OS X 10.6. After I rebooted the machine, it wouldn't show the login screen anymore, but only show a blue screen. This blue screen would change color repeatedly.

I can't get into the system to uninstall TeamViewer, so what can I do now?

I put this here for reference because I just ran into the issue and couldn't find a solution on the internet anywhere.

Yes. Macs have blue screens. Sort of.

Reboot your Mac, and immediately after booting, hold Cmd-S. It will boot into Single User Mode, where you can modify your existing file system.

Enter the following:

/sbin/fsck -fy
/sbin/mount -uw /

Now, let's delete the Launch Agents and Daemons that TeamViewer Host installed, which are the possible cause of the window server crashing:

rm /Library/LaunchAgents/com.teamviewer*
rm /Library/LaunchDaemons/com.teamviewer*

Finally, reboot your Mac by entering:


You'll be able to log in again. To completely uninstall TeamViewer Host, run its uninstaller from /Applications.
