Well, back to the actual topic of this thread, I too need to be able to run ProTools with both the MBox and 002Rack, and quite frankly, I can't believe that Digi would be so stupid as to not allow for this. Tech support told me today that the solution was to repartition the drive, with one version of proTools on each. Are they kidding? Reformat my drive because of Digi's poor code writing? As you may have guessed, I'm PISSED! Tonight I'll try to make a new user and install the new 6.0.2 into an applications folder within the new home folder. Keep your fingers crossed.
