This has been an ongoing problem for a long time now. If I was to ever quit Teamviewer, it would cease to reopen, and instead, just give me a prompt saying “TeamViewer is trying to install a new helper tool”.
Today, I finally discovered the answer to my troubles, and hopefully a solution that will work.
I discovered it here.
What happening on my computer was that the launch daemon for the helper tool was not properly started.
So, to fix the problem, I ran this from the Mac terminal:
sudo launchctl load -w /Library/LaunchDaemons/com.teamviewer.Helper.plist
Teamviewer then finally loaded. I haven’t seen anyone else with this issue, so I don’t know why it is doing it, but, until the Teamviewer provide a proper solution, this work around will have to do.
Sadly, even with the latest version (14), this is still current.
