Rumors of an M4 update to the MacBook Air in 2025 have been boosted, thanks to a leak buried inside Apple's macOS Sequoia 15.2 update.

The macOS 15.2 update that was released earlier today came with a handful of new features, plus something unexpected: an apparently accidental reference to the upcoming M4 MacBook Airs. MacRumors reports that the "Mac16,12" and "Mac16,13" model identifiers reference 13- and 15-inch models of the M4 Air and that both are coming in 2025.

Apple has pushed the MacBook Air as one of the best laptops for consumers for nearly two decades, but the next macOS laptop will leave many in the community disappointed.

The M3 MacBook Air was introduced on March 4, 2024, but it seems that the timeline for the M4 MacBook Air is moving forward, with a release expected in early 2025. According to Bloomberg, Apple is likely to unveil new MacBook models between January and March 2025, suggesting that details about the M4-powered MacBook Air will emerge soon.'

Apple hasn't officially announced M4 MacBook Airs but rumors suggest these laptops could arrive in early 2025.

The MacBook Air isn’t a perfect computer by any means, but there are some simple upgrades that I’d like to see Apple make with the M4 MacBook Air early next year. Any of these upgrades would make it a much better package in my book.
