same problem I had on my macbook pro. Bricked my phone till I got VMWare Fusion installed on my mac. Originally had Parallels 3 installed and that wouldn't let me do anything in DM or BBSAK - wouldn't even connect to my Storm most of the time. Upgraded to Parallels 5 after reading that might fix it. BBSAK and DM both worked perfectly to backup everything in Parallels 5. When i got to the point of wiping my phone with BBSAK and the reloading the shrunk down hybrid OS with DM Loader.exe, I got the above stated problem: phone kept rebooting during "connecting to boot rom" step until the loader gave me an error after several tries. Frustrated and with a bricked phone at this point with no OS, I installed VMWare Fusion as a last ditch effort, and everything worked using windows in VMWare without a hitch. I think the problem is the way Parallels shares the USB connection with the host OS X machine. I guess VMWare handles it better for DM and BBSAK.
