According to Jon Prosser MacBook Air will feature a new design and colors similar to the new iMac designs. Jon Prosser has allegedly revealed accurate photo renditions of what new MacBook Air. On Prosser's YouTube channel, Front Page Tech, he continued adding to his previous predictions of the new MacBook Air designs. Some of his predictions included the new design will be made with an M2 chip, the upgraded version of the M1 chip recently released. Another one of his predictions is that the machine will no longer have the tapered, but will be thinner overall. The keyboard is predicted to have full-sized function keys and white in color. This would push the trackpad down, making it smaller.
