    That is the DFU Mode bug found in the latest update of the Mac OS X. There are a few ways around it. Easiest way being using a Hub. For more information check out the Dev Teams blog.

    As noted previously OS X 10.5.6 introduced a bug that affected the use of DFU mode. with some Macs. There have been previously published hacks and techniques to fix this, but here is another method that can be used to temporarily restore DFU functionality in order to use QuickPwn or PwnageTool.

    You will need an account with ADC (Apple Developer Connection) this is free and takes a few minutes to sign up, you should read the terms and conditions carefully and you should only sign up if you are thinking of developing applications in the future - Apple Developer Connection - Mac Dev Center
    Download the disk image IOUSBFamily-315.4-log.dmg for Mac OS X 10.5.5 Build 9F33 (yes, that is a 5 in 10.5.5 - this is a developer debug package of the USB kernel extension).
    Unplug non-vital USB equipment, such as external DVD writers, USB scanners, USB mass storage devices, at the most leave a Keyboard and Mouse connected.
    Install IOUSBFamily-315.4.1.pkg from within the disk image
    Reboot your system!
    Perform necessary DFU activity with QuickPwn or PwnageTool.
    Download the disk image IOUSBFamily-327.4.0-log.dmg for Mac OS X 10.5.6 Build 9G55
    Intall IOUSBFamily-327.4.0.pkg from within the disk image
    Reboot your system!
    Reattach your USB peripherals.

    That is your best bet, preferably a Windows machine. Ironic eh?

    It's pretty complicated for something so simple. I just used my Windows machine. First time it was turned on since I got my Mac.
