So this is my first mac, and one of the reasons I purchased this 2011 15" MPB is so I can keep using virtual machines. Since I usually use Virtual Box, I decided to stick with the same software since it has worked so well for me on many PC's. However, for some strange reason, installing Windows XP is taking me hours (started this morning, it's still installing). I don't think it's a guest driver related issue, since even selecting the hard drive to partition takes many seconds before the cursor moves. I can't find anyone else complaining about this issue, so I decided to post it in this forum in case it's some strange compatibility issues with the new laptops. Is anyone else experiencing this issue? If you are able to use XP with the latest version of Virtual Box, I would love to hear from you as well. Thanks!
