This is possibly a non-issue, but the Finder icon that appears when you Cmd + Tab has some strange graphical noise on the top. I can't remember how long ago it happened, or if I made anything strange before it appeared.

Does anybody have an idea of why this happens? I'm on a 13' MacBook Air 2011 with 10.7.5.

And it's only on your Finder icon? – Michiel Feb 20 '13 at 14:47
@Michiel yes, it only appear over the finder icon – Duopixel Feb 20 '13 at 14:53

It's likely the Finder's application icon is corrupted.

To check, navigate to /System/Library/CoreServices/ and select Get information on the file and see what the icon looks like.

I'm not sure where you can get a replacement icon (maybe another computer or the install disks with some package exploration). I'd post mine here but for Apple's remarkably strict copyright lawyers.


Navigate to ~/Library/Preferences and move the file to your desktop. This may result in your dock items needing to be reloaded. Logout and back in.

Good clue, but icon looks OK if I do Get Info. Hmmm... – Duopixel Feb 20 '13 at 16:42
In that case it's probably your dock. Have you tried logging out and back in or restarting your machine? – zwerdlds Feb 20 '13 at 18:18
Hmmm if it's the dock then it might be related to this other problem I have…. It happens even if I restart but the dock is a good clue. – Duopixel Feb 20 '13 at 18:38
Now this is weird, it's getting progressively worse: – Duopixel Feb 25 '13 at 8:38
Navigate to ~/Library/Preferences and move the file to your desktop. This may result in your desktop needing to be reloaded. Logout and back in. If the distortion is not gone, move the file back from your desktop. Also, are other users (even the guest user) encountering this issue? – zwerdlds Feb 25 '13 at 15:47
