Hello everyone. As you can tell I'm new here and I will be receiving my first MacBook in a few days. I have a Windows XP OEM disc with Service Pack 3 on it. I did some research and learned I should update to Boot Camp 2.1 before installing. I'm confused about updating though. Do I download and install the update while I'm in OS X or did I need to do this while I'm in Windows? Thanks for your time..
