Miguel Alvarado has found a glitch that lets users delete an iCloud account from an iOS 7.1 device without the Apple ID password. In this YouTube video, he demonstrates tapping the Delete Account button and the Find My iPhone switch simultaneously, then restarting the iPhone when the both prompts appear simultaneously. When the iPhone booted back up, he was free to remove the iCloud account, which disabled Find My iPhone. There’s some speculation that this may not affect all iPhone models; although we could replicate it on an iPhone 5s, we were unable to do so on an iPhone 5. Nonetheless, we hope Apple releases a fix soon, and in the meantime, make sure to use a passcode. follow link
Option-Click in Scroll Bars for Jump Scrolling
In Mac OS X in general, and thus in most native Mac OS X applications, hold down the Option key and click anywhere in a window's scroll bar to jump to that spot (rather than scrolling one screen). If you like this behavior, you can make it the default in the Appearance preference pane. For "Click in the scroll bar to:" select "Jump to here."
