Hi gurus, I've just ordered a MBP for my Wife and she's kindly donated her Dell laptop to me in exchange. I'd like to have a go at getting OS X on this. I've created a USB drive using the latest Unibeast and Multicast, but I can't get past the initial screen (with the USB icon in the middle & what looks like a cherry at the top). I press enter (as I presume USB is already selected) and then I get a grey loading screen with a progress bar, but then the screen goes black and stays there. Can anyone help please? Cheers.
