A few days ago, when I start my OS X, I see that a few key icons are gone: including the clock, WIFI, battery and various other things.

I did the following:

  1. Remove the file ~/Library/Preferences/com.apple.systemuiserver.plist
  2. run killall SystemUIServer in the terminal.

The icons did come back. However after restart the icons are gone again.

Other symptoms include: whenever I connect to my WIFI, and then open any application, they will get shutdown immediately, giving error messages like:

Please run the gather_files.sh command that's attached to the radar
sudo gather_files.sh

These disappears after a day, but the icons are still gone. How can I get those icons back?

I am using OS X Mavericks 10.9.2

This worked for me:

  1. Reboot and hold shift key to enter safe mode
  2. Launch Safari
  3. Reboot normally
