If you’ve recently jailbroken your iPhone, read on. If you haven’t, stop — this article won’t help you. If you’re still reading this, you’re probably frustrated because everytime you close the MBP’s lid, it just cycles from sleep->awake over and over again. This is because you applied OS X 10.5.5’s IOUSBFamily-315.4.1.pkg to your computer to Jailbreak your iPhone in DFU mode. But you FORGOT to reapply OS X 10.5.6’s IOUSBFamily-327.4.0.pkg to your laptop. It’s easy to forget this step when you’ve just jailbroken your iPhone and all. Just a heads up

You can download both the IOUSBFamily-315.4.1.pkg and IOUSBFamily-327.4.0.pkg here, but you’ll need to sign up for an Apple Developer Account first (it’s free!).
