MacBook Air 15インチ 2024

The 2024 15" MacBook Air was the second 15" Air to be released. It's very similar to its predecessor, with the main difference being the updated M3 chip. The 15" M3 MacBook Air was released on March 8th, 2024, with base models starting at $1,299. Just like last year's model, the 15" M3 MacBook Air is available in Silver, Starlight, Space Gray, and Midnight.

The 15" MacBook Air with the M3 chip is identifiable by model number A3114, which is on the bottom edge of the back cover. You can get more information about your laptop by selecting About This Mac from the Apple menu  in the upper-left corner of your screen. The laptop has a MagSafe port and two Thunderbolt ports on the left edge, and a headphone jack on the right edge. There's a "notch" on the top edge of the display for the camera, and a Touch-ID/power button on the top right corner of the keyboard. This MacBook Air comes in four colors: Silver, Starlight, Space Gray, and Midnight.
