New renders show an unannounced MacBook Air with new white keycaps and more. Leaker Jon Prosser says the renders are based on images of MacBook Air parts he has seen photos of. Leaker Jon Prosser today shared a new video detailing what he believes to be the next generation of MacBook Air. The renders shared by Prosser are said to be based on images of MacBook Air components that he has seen. The most obvious change in the new MacBook Air design is the removal of the wedge shape design, making this appear to be an impossibly thin computer. But there's more going on here, too.
