Symantec “endpoint protection” (antivirus to you and me) came installed on my new work mac, and because I’m a subservient oik, I’ve not fettled with it before, but the updates have begun to irritate. Basically the updater seemed to be running on a schedule, resulting in a delightful bouncing ball in the dock every hour or so (certainly every time I restarted).
I found a fix over on symantec’s forums. open up a terminal window and you can edit the scheduling for all users on the box (as long as you have root permissions). Here are the magic words:
(Lists the current schedules)
(deletes all the current schedules)
(creates a new schedule, daily, with the quiet flag set).
