MacBook – help weird icon on the menu bar

The best way to get an app to stop appearing in the menu bar is to make it stop opening automatically when you log in. Here's how:

I believe that this app is just a login item. Here's how to remove it from your Login Items list.

Open System Preferences (/Applications). Go to Users & Groups -> your account -> Login Items. Click the lock at the bottom left and enter your password. Find the Quick View app in the list, select it, and click the minus sign below the list.

Hope this helps!

Here's a youtube video that covers how to do this in Mountain Lion: https://www.youtube.com/watch?v=y8wqOkrlX5Q

It appears to be the same in mavericks. The easier way to get to the folders in Finder is click Go > Go to Folder, or hit Shift-Command-G and in the window type /System/Library/PrivateFrameworks/LoginUIKit.framework/Versions/A/Frameworks/LoginUICore.framework/Versions/A/Resources and the other folder is /System/Library/CoreServices.

The files in Mavericks seemed to be named apple_s1.png, apple_s1@2x.png, apple.png and apple@2x.png.

Good luck
