Hi, Have Parallels installed on macbook (10.4.11), and tried installing but got an error message flashed saying I didnt have enough ram (macbook has 1gig), while the requirements for PC is 512 or 1gig for Vista (im using XP) - Is my machine literally splitting half the ram or is their somewhere i can give it more juice? Or, do I simply need to purchase more ram? Cheers for help
