Apple released a new macOS Yosemite update that accidentally lists the unreleased M4 MacBook Air models. The launch must be close.

Seemingly, for the first time in forever, Apple will be updating every single Mac with an M4 chip, presuming rumors hold correct. There have been a number of times where this has been close, but it hasn’t happened anytime in the past decade, at least.

Apple left references to MacBook Air M4 13-inch and 15-inch models in the macOS Sequoia 15.2 release, suggesting they're on track for early 2025.

The M3 MacBook Air has been hailed as the best ultra-portable laptop that will grace 2024. The M4 will go higher with better performance, more memory, and enhanced features for the camera. However, exciting as these leaks are, they remain mere speculation until Apple puts that official stamp on it.

Apple's latest macOS code contains references to two unreleased M4 Macs. It suggests we'll be getting new 13-and 15-inch MacBook Air models – likely in spring 2025. Apple's code is a bit like a pirate's treasure map: it can tell you where valuables can be found.
