MacBook Air Buyer's Guide: Comparing the Generations

Apple's MacBook Air has undergone some major changes in recent years, including the switch to Apple silicon, a complete redesign, and the introduction of a 15-inch model, making it all the more important to consider if now is a good time to upgrade or if an older model will suffice for your needs.

Following its latest refresh, Apple discontinued the M1 13-inch ‌MacBook Air‌ from 2020 and the M2 15-inch ‌MacBook Air‌ from 2023. Now, customers can choose between the ‌M2‌ 13-inch ‌MacBook Air‌ from 2022 for $999, and the M3 13- and 15-inch MacBook Airs that were just introduced for $1,099 and $1,299, respectively.

See the breakdown below for each new feature, change, and improvement that was added with each ‌MacBook Air‌ model since 2018 compared to its direct predecessor:

  • 1.25 kg (2.75 pounds)

‌M2‌ ‌MacBook Air‌ users have very little reason to upgrade to an M3 model unless they need absolute peak performance and don't want to buy a MacBook Pro, or perhaps if they purchased the 13-inch machine in 2022 and are now interested in the 15-inch M3 model.

Most ‌M1‌ ‌MacBook Air‌ users will stand to benefit from upgrading to the M3 model, especially if they are looking for a bigger screen and opt for the 15-inch model. These users would gain a much more modern design, a larger and brighter display, better performance, faster memory, a 1080p camera, improved speakers, ‌MagSafe‌ 3, fast-charging, and more. Nevertheless, some ‌M1‌ ‌MacBook Air‌ users may be better off waiting for the next major refresh if they are still happy with the machine, and upgrading is not essential.

For those who have an Intel-based ‌MacBook Air‌, either of the generations currently on sale represent a highly worthwhile upgrade spearheaded by Apple silicon for a major performance improvement and upgrading is recommended, with many of the above upgrades quickly stacking up.

Here Are the macOS Sequoia Features Intel Macs Won't Support

When Apple released macOS Monterey in 2021, some key features required a Mac with Apple silicon. The same scenario played out with macOS Ventura in 2022, and then again the following year with the release of macOS Sonoma. With macOS Sequoia set to arrive in the fall, which new features can Intel Mac owners expect to be unavailable to them this time around? Apple says that macOS Sequoia is compatible with the same Macs as macOS Sonoma, but Apple's fine print reveals that certain new features won't work on Intel machines. If you're still on an Intel Mac, here's what you won't have access to. Apple Intelligence Apple Intelligence , a deeply integrated, personalized AI feature set for Apple devices that uses cutting-edge generative artificial intelligence to enhance the user experience, won't be available on Intel Macs.
