The Pangu development team today updated its jailbreak for iOS 8 and 8.1, bringing full support for the Mac



From MacRumors:

Pangu's jailbreak tool for iOS 8 is the first that is compatible with any device running iOS 8.0 to iOS 8.1, including newer devices such as the iPhone 6, iPhone 6 Plus, iPad Air 2, and iPad mini 3. The jailbreak method allows users to install content like themes, tweaks, and apps from other sources than the App Store. The Pangu development team recommends that users backup their iPhones, iPads, and iPod touches before using the tool, and notes that devices upgraded over-the-air may need to be restored before being jailbroken.
