My apologies in advance! I probably bit off more than I can chew, but I just bought my first Macbook Pro Unibody yesterday and would like to be able to boot into BT4 from USB flash. I've been able to successfully do this before on my Windows PC, but everything is a little foreign on this Mac. So far I have my 8gb USB stick, downloaded BT4 iso to my desktop and.....??? Not sure what to do next.. I've done some searching already on the forum, but I'm not finding anything too specific to Macs.. Thanks for your help in advance..
