These are instructions on how to enable DFU mode detection in Mac OS X 10.5.6. In order to pwn your iPhone for jailbreak or unlock you will need to have iTunes detect your iPhone in DFU mode. Normally this was not a problem; however, it seems Apple has disabled this ability in OS X 10.5.6.

Volkspost from has released an Automator program to fix this. You can find instructions below on how to use it. A big thanks go out to him for his efforts.

Full tutorial with screenshots: How to Enable DFU Mode in Mac OS X 10.5.6 - Answers4PC Blog

***WARNING: While this does not affect all users, it is possible that QuickTime 7.6 may freeze your keyboard and mouse. Please uninstall this patch before installing QuickTime 7.6

***ALTERNATIVE: Rather then following this tutorial a much easier solution is the use of a USB hub between your iPhone and the computer. If you are not an advanced user it is suggested that a USB Hub be used

Step One
Download the Automator program( from here and save it to your desktop.

Step Two
Double click the downloaded zip( on your desktop to extract it.

Step Three

Double click the extracted folder(Install_IOUSBFamily_kext_10_5_5) to open it.

Step Four

Double click the Fix_DFU_10_5_6 icon to launch the Automator script.

Step Five
If warned that the application was downloaded from the Internet click the Open button.

Step Six

You will then be displayed the Readme for the script. Make sure you are logged into Mac OS X using an administrator account then click the OK button.

Step Seven
The Automator script will then attempt to close all open applications. A window will pop up asking for your Administrator password. Enter the password then click the OK button.

Step Eight
Another dialog box will appear informing you that caches necessary for boot are being updated. Click the OK button.

Step Nine

Your computer will then reboot. Once it has you will be able to detect an iPhone in DFU mode again.

The full procedure of the Automator program is as follows:

1. checks if you are at Mac OS X 10.5.6 or better (if not will quit)
2. show a readme
3. quits all running apps (with save option)
4. backup the original files (AppleUSBHub.kext and IOUSBCompositeDriver.kext from 10.5.6) in a new folder on your Desktop
5. ask for your admin password
6. copy AppleUSBHub.kext and IOUSBCompositeDriver.kext from 10.5.5 into the desired location on your Mac
7. set owner:group and permissions
8. rebuild the kextcache
9. reboot your Mac
