I can’t believe this. Bulletfreak, the guy who’s free software if possible on everything is making a guide on installing Mountain Lion on a Thinkpad. Yes, that’s right. With the help of other’s trial and error of course. First head to this site: http://bit.ly/18nw5HF . I'll keep you up to date as i install it both in a virtual machine and a full system install. See you then!
