macOS Monterey is expected to launch this fall alongside new MacBook Pro models featuring custom-designed Apple silicon that would be faster successors to Apple's much-lauded M1 chips found in lower-end Macs and the most recent refresh of the iPad Pro.
(A similar change replaced the 15-inch MacBook Pro with a 16-inch model a couple of years ago.).
So increased screen resolutions join a plethora of other likely changes that would make for the most significant redesign of the MacBook Pro since the first Touch Bar models in 2016.
