Google drive app not working in OSX Yosemite
I found this workaround/fix:
- Open Terminal.
Paste the following command:
sudo cp /Applications/Google\ Drive.app/Contents/Resources/Google\ Drive\ Icon\ Helper /Library/PrivilegedHelperTools/- Enter your password.
- Either restart your machine or use Activity Monitor to force quit Google Drive and restart the application.
The accepted answer didn't work for me, but this did...
Delete the Drive settings directory ~/Library/Application Support/Google/Drive
