Apple is gearing up to release an update to its MacBook Air line, with Bloomberg's Mark Gurman reporting that the 13-inch and 15-inch models will be bumped up to M4 chips in March. This move will mark the completion of the M4 transition across Apple's MacBook line, with only the Mac Studio and Mac Pro remaining on M2-generation chips.

The update is expected to bring the MacBook Airs in line with the low-end MacBook Pro, which features 10-core CPUs and 10-core GPUs, as well as 16GB of RAM. It's likely that the new Air models will also inherit the Pro's ability to simultaneously connect to two external displays with the lid open, a key upgrade that will enhance user productivity.

As is typical before a product launch, Apple is preparing its marketing, sales, and retail teams for the debut, and is allowing its retail stock of the current laptops to clear out. This suggests that the company is confident in the demand for the updated MacBook Airs and is taking steps to ensure a smooth rollout.

The M4 chip update will bring the MacBook Airs up to par with the rest of Apple's laptop lineup, which has been gradually transitioning to the M4 generation. The Mac Studio is expected to receive its M4 bump between March and June, while the Mac Pro's update is slated for anywhere from June to this fall.

For users, the M4 update is likely to bring improved performance and efficiency, as well as enhanced features and capabilities. The exact specifications of the updated MacBook Airs remain to be seen, but based on Apple's past updates, it's likely that the new models will offer significant upgrades over their predecessors.

The news comes as Apple continues to refine its laptop lineup, focusing on delivering high-performance machines that meet the demands of modern users. With the M4 transition nearly complete, Apple is poised to maintain its position as a leader in the laptop market, offering a range of machines that cater to different needs and budgets.

As the launch approaches, users and industry watchers alike will be eagerly anticipating the release of the updated MacBook Airs, which promise to deliver a new level of performance and capability. With Apple's reputation for delivering high-quality products, it's likely that the M4 MacBook Airs will be a hit, further solidifying the company's position in the laptop market.
