ok, i heard soemthing about DFU not working on the new macbook or something? i have 2.1.1 firmware =D... one of the lucky few who didnt upgrade. will i get any errors?

Yeah, you didn't hear? New macbooks are incompatible...sorry man, it's somewhere on the dev team's page...

If you use a USB hub or something along those lines, it will work.

It's not just the aluminum macs it's all macs with 10.5.6+. There is a fix however. Here: http://www.hackint0sh.org/forum/f146/60657.htm#post374065
