Hi I found your project very interesting and I would like to buy everything to make a similar device. you mentioned that for a Macbook Air 2013 (bought on August 24th) it is the same configuration and the same process isn't it ? However I would like to know two things: - First, (Maybe a stupid question but did not see anyone writing about it) Can I connect an external screen to be able to use games on a much bigger screen than the macbook air 13" if yes is it worthy ? - Second, what do I need to change to configure the e-gpu on a macbook air 13" mid-2012 ? Many thanks in advance
