Working remotely - no way of visiting the office as it's thousands of miles away.
Just foolishly installed the beta after unintentionally "upgrading" the management console to v12. (A poorly thought-out scheme. You should have a choice of building v11 modules, but I digress.)
Having realised that I'd installed v12, I tried to find the uninstall. Not there. Okay, I've manually uninstalled TeamViewer before. Went through the LaunchAgents, LaunchDaemons, PriviledgedHelperTools and Preferences. Deleted the app. Restarted
Mac was not visible on the network but appeared to be alive. That's okay, the Macs are setup for Apple Remote Desktop. Nope.
SSH'd via Terminal, all seemed fine, reset the ARD agent, still couldn't get control. In the Home folder... rm -rf .Trash ... reboot... nope
Had to remotely reinstall TeamViewer Host from the command line (see below if you ever need it, you may need to check the URL is still active)
curl -O http://downloadeu1.teamviewer.com/download/TeamViewerHost.dmg
hdiutil mount TeamViewerHost.dmg
sudo installer -pkg /Volumes/TeamViewerHost/Install\ TeamViewerHost.pkg -target /
Once it installed... sudo reboot
...and the Mac was visible again through Remote Desktop.
Hopefully, they'll rollback the management console to v11 modules.
Thank you for your inquiry.
For the v11 rollback one of our representatives will me messaging you shorty.
Also we thank you for posting some advanced tips for Mac users that may not be commonly known.
Thank you for using TeamViewer and for supporting the TeamViewer community.
I am having this same problem. There is no Uninstall Button in the Team Viewer preferences.
I am Version 11 on MacOS Sierra.
Please advice, I would like to do a full uninstall.
It looks like the problem is with removing TeamViewerAuthPlugin.bundle from /Library/Security/SecurityAgentPlugins - one cannot just delete it, it needs to be removed properly. Unfortunately, it's not clear how. There's a database which needs to be updated.
