I am going to be purchasing a new Macbook Pro once they get updated (MWSF, if not then then later). I was wondering if I need to start the machine up for the first time with the original RAM or can I just open the box, install the 4GB, then start up for the first time? My instincts say it would be fine but switching from Windows, I do not know if there would be a setting that I would need to change or anything. Thanks for the help.
