Hey, I have the old school 17" MacBook Pro I say old school, I mean pre-no button on the trackpad-redesign. I want to Travel to the UK and my Macbook was purchased from the Canadian Apple Store. I was wondering if anyone would be able to tell me if I can use my Macbook there? Because of the different voltage, that I don't really understand. Also, I'm going to the UK for about 4 months and I'd like to buy the power adapter for my computer. Just wanted to be sure I could do that.
