Here are 7 upgrades the MacBook Air M4 offers over the MacBook Air M1. The most obvious upgrade between the laptops is their respective designs. The MacBook Air M4, like its M3 and M2-powered predecessors, features a sleek and minimalist square design. In contrast, the M1 Air’s once-inconic tapered design now appears ancient.

The entry-model M4 Air will be $100 less expensive than its M3 equivalent. I got an early look at these beefier MacBooks, plus a Mac Studio juiced with M4 Max and M3 Ultra.

The MacBook Air M4 supports the latest Wi-Fi 6E, whereas the M1 variant is limited to Wi-Fi 6. Additionally, it features Bluetooth 5.3, and its 3.5mm headphone jack can drive high-impedance headphones—something missing on the MacBook Air M1.
