Flashing icons (crashing gui) in OSX Yosemite Since yesterday the icons on the top-right of my macbook (yosemite) are constantly flashing. Looking at system.log it seems like the gui is crashing and restarting every second. Here is a copy of the crash report.

This started happening quite suddenly, I didn't perform any system changed. The only thing I did recently is install a printer driver, but I doubt that that is related.

With Problem (no icons showing)



as it should be (all showing)
Tracking your problem in Crash report it shows

So one of the existing icons is making problems, my hint is the Volume or the Clock.

One way to find out is to trash them one by one (hold cmd and pull it to the desk top). No worry they can be easily restored from here /System/Library/CoreServices/Menu extras.
