whenever the notification banner that appears on the top right of my screen appears, it's covered by a smudge. I can't find any other other answers online that deals with this problem and it's starting to really annoy me.

  • Can you post a screenshot? – bjbk Aug 9 '15 at 19:53
  • @bjbk yeah, just did. only appears for notifications – Joe Aug 9 '15 at 20:40
  • it is always there, just not visible if no white background. – Ruskes Aug 10 '15 at 0:36
  • @Buscar웃 the smudge only appears when the notification appears, it vanishes when the notification goes away. you can't see it when there is no notification on the screen – Joe Aug 10 '15 at 1:09
  • So if you have a white background or a full screen app it is not there? – bjbk Aug 10 '15 at 2:03

Try to completely disable Notification Center, reboot, then reenable.

To do so, (with caution, of course) try the following:

  • Launch the Terminal app from /Applications/Utilities, enter the following command, and press Return:

launchctl unload -w /System/Library/LaunchAgents/com.apple.notificationcenterui.plist

  • Reboot

  • Now re-enable Notification center:

launchctl load -w /System/Library/LaunchAgents/com.apple.notificationcenterui.plist


I have searched in vain to find any information regarding a .plist or other file containing appearance settings for notifications thinking that somehow these had become corrupt.
