Update: The video titled "OS X on Dell Laptop" appears to be in fact fake, that being the case it has been removed.
When Apple made a statement saying that OS X will only be sold/will run on Intel machines that Apple makes itself, the hopes of installing OS X on your home PC flew away. However, it turns out that one individual decided to take on Apples statement. This individual managed to install OS X on his Dell laptop (please see video below). While this video cannot be confirmed, it does look genuine and if thats the case well be hearing a lot more success stories about this in the next coming weeks.
