I've bought a Macbook Pro Retina display before Mountain Lion was released. I have signed up for a copy of Mountain Lion for free, as promised by Apple if you purchase an Apple computer after June 11, 2012. When I finished the application form, the page said to wait till I get an email from Apple.
The problem is I don't know how long to wait. If past is prologue, how long is it before I can expect to get Mountain Lion? It has been three hours, and I still have not received an email.
