While the 13-inch MacBook Air with the M2 chip initially supported Bluetooth 5.0 when it was released in July 2022, the laptop now supports the faster and more reliable Bluetooth 5.3 standard, according to Apple's tech specs.

Apple updated the 13-inch MacBook Air's tech specs page to say Bluetooth 5.3 after introducing the 15-inch MacBook Air with Bluetooth 5.3 at WWDC earlier this month. The latest standard offers faster and more reliable connectivity with Bluetooth accessories, and improved power efficiency, which can contribute to longer battery life. More details about Bluetooth 5.3 are available on the Bluetooth website.

All new Mac, iPhone, iPad Pro, and Apple Watch models released since September 2022 support Bluetooth 5.3, as do the second-generation AirPods Pro.

Both the 13-inch and 15-inch MacBook Air remain limited to Wi-Fi 6, while other new Macs support Wi-Fi 6E for faster wireless connectivity over the 6GHz band.
