Desktop background changed
When I started my Mac, there was a new desktop background. Anyone know what this means? Thanks!
iMac, iOS 8
iMacs don't run iOS. You can customize the desktop background through Apple menu -> System Preferences -> Desktop and Screen Saver with Mac OS X. If you have a different background it could mean a different user is logged in, or you have a program that is defaulting to a Space with a different background through Mission Control in System Preferences. Prior to Mac OS X, the operating system forum you posted to, application such as DéCor let you customize your wallpaper. Without knowing what you are running, it is hard to say. Go to Apple menu -> About This Mac. And then knowing what you are running decide whether to pick a different forum to get your answer:
