Mark Gurman, writing at Bloomberg:
The 15-inch model under development is a wider version of the 13.6-inch MacBook Air that Apple announced this week. That design, unveiled at the developers event Monday, is thinner than recent models, relies on the M2 chip and abandons the previous wedge-shaped frame. It’s considered to be the biggest overhaul to the MacBook Air since it was introduced by Steve Jobs in 2008.
Apple has also begun work on a new 12-inch laptop and is considering launching it at the end of 2023 or in early 2024. If Apple moves forward with the release, it would represent the company’s smallest laptop since it discontinued the 12-inch MacBook in 2019.
