看这个,apple support communities上的那个帖子,Removing com.google.keystone.daemon:
"I have tried every suggestion that I can find to disable Google's auto update including the Terminal command:
sudo /Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Resou rces/
GoogleSoftwareUpdateAgent.app/Contents/Resources/install.py --uninstall
According to my Console, this software update is being launched every 10 seconds. All Google software has been removed, as well as all Google Keystone related .plist that I could find, but to no avail.
Have anyone found a viable solution to this agent that continues to flood my Console searching for something that seemingly doesn't exist?"
