Apple's macOS Sequoia Update Leaks Upcoming M4 MacBook Air Models

Apple has accidentally leaked information about two upcoming MacBook Air models through a macOS Sequoia 15.2 software update. The update, which was mistakenly released for machines that have yet to be launched, contains software files for “Mac16,12” and “Mac16,13.” These correspond to new 13-inch and 15-inch MacBook Airs, set to feature Apple’s next-generation M4 chips.

The software references confirm the upcoming devices as the “MacBook Air (13-inch, M4, 2025)” and “MacBook Air (15-inch, M4, 2025).” While Apple has not officially announced these models, the accidental release offers a glimpse into the company’s 2025 MacBook Air lineup, expected to feature the M4 silicon and bring further improvements to performance and battery life.

The mistake underscores Apple’s continued development of its M-series chips and its ongoing push to refresh its MacBook Air line, which remains one of the most popular models among consumers. With these updates, Apple is expected to further solidify the MacBook Air’s position as a top choice for everyday users and professionals alike.
