Ross Young, an analyst with the Display Supply Chain Consultants, said that Apple will miss out on mini-LED and ProMotion technology in its rumored 13- and 15-inch MacBook Air models.

Young said that the MacBook Air will have a display size of 13.6-inches. It would be larger than the current Macbook Air, but still smaller than the current MacBook Pro. The new display size will be accommodated by a complete redesign that moves away from the current tapered profile in favor of a thinner, MacBook Pro-like chassis.

Young reported earlier this week that Apple was working on a larger, 15-inch Macbook Air model. Mark Gurman said last year that Apple was working on a larger, 15-inch Macbook. The device may be called the "MacBook" rather than the "MacBook Air" according to respected Apple analyst.

Young said that the 15-inch Macbook will have an exact display size of 15.2 inches. Until the introduction of the 16-inch MacBook Pro in 2019, this is 0.2-inches smaller than the 15-inch display size that Apple previously offered on its larger MacBook Pro model. The 15-inch MacBook Air could have a noticeably smaller overall size if it were thinner than the now-discontinued 15-inch MacBook Pro.

Young told MacRumors that the new MacBook Air models won't have mini-LED display or ProMotion technology. Young maintains that the two new Macbook Air models will not get a mini-LED display.

Young has revealed a wide range of accurate insights into Apple's plans, such as the size of the sixth-generation iPad mini, the ProMotion display, and the MacBook Pro's mini.
