I just downloaded the security update for 10.4.11, and previously my computer would recognize DFU without a problem. Now, however, when I go to jailbreak on redsn0w 0.7.2 PPC, it doesn't recognize DFU. It also doesn't recognize the iPod in DFU without using redsn0w. Before the update, it would recognize DFU without a problem. Is anyone else having this problem?
