Since there were no obvious guides on this, just thought I would make an update. In order to follow any of the current jailbreaking guides, you must have a USB Hub or you must download an Automator script. This goes for ALL Macs, not just the new unibody ones. However, it appears that the USB hubs are hit or miss for most people. So, if you have a USB Hub that worked, post it's make/model so that other people can find a working one. I used the hub that came with RockBand 1 on my Wii. I HAVE NOT TRIED THIS SCRIPT MYSELF, USE AT YOUR OWN RISK. IT MAY CAUSE PROBLEMS WITH YOUR COMPUTER, ESPECIALLY IF YOU OWN A UNIBODY MAC. Instructions for use can be found <link removed>* Make sure you follow all directions and understand risks before using this tool. The automator script can be found <link removed>* I hope someone found this useful, as it was stated (at least to my knowledge) in any of the guides I followed. EDIT: Removed links, if you really want to take the risk, you can find them.
