I recently bought a 15" top-end MBP and now I'm getting an issue where its' freezing up with a grey screen and then a message pops up saying 'you must restart your computer' At the time I'm usually connected to an HDMI TV, listening to iTunes, tethering from an iPhone and typing Word docs at the same time; but I would expect a $2500AU 'Pro' computer to be able to handle that! And its happening more and more! So my question is, if I take it back to Apple, would they; a) fix it. b) Give me a full refund? I want to swap it for an 11" MacBook Air and then build my own PC for gaming with the leftover money. I realise now that a Mac computer is definitely NOT for gaming, if that is the intended reason for purchase. Thanks dudes!
