M4 MacBook Air
The model that kicks off the 2025 Mac releases will be the M4 upgrade to the MacBook Air., which will likely land between January and March. The current M3 MacBook Air was released in March 2024, so the M4 model will arrive about a year later.
With the 14-inch M4 MacBook Pro, Apple introduced other changes to go along with the new chip: an additional Thunderbolt/USB 4 port, an increase in RAM from 8GB to 16GB, an option for Nano-texture glass, and a Space Black color option. Rumors have indicated that the M4 MacBook Air will be little more than a chip upgrade, but any of these options could make an appearance.
The M4 MacBook Air will be released in the early part of 2024.

However, there’s one functional change that will likely arrive with the M4 MacBook Air With the M3 MacBook Air, you can run up to two external displays (one at 6K/60Hz, the other at 5K/60Hz) with the laptop closed. The M4 chip in the MacBook Pro has more robust support, where you can run two external displays in addition to the laptop’s display, for a total of three usable screens.
Now, maybe thermal considerations prevent the M4 in the MacBook Air from having the same support as the M4 in the MacBook Pro, but we still think it’s a likely upgrade. Also, Apple upgraded the M3 MacBook Air with 16GB of RAM during the M4 Mac release, so it’s a lock that the M4 MacBook Air will start at 16GB, too.
