MacBook Air (15-inch, M5, 2026)

Overview

The MacBook Air (15-inch, M5, 2026) combines a spacious display with a thin, fanless design. It is suitable for users who want more room for documents, creative applications and entertainment without moving to the heavier MacBook Pro.

Its M5 chip includes a 10-core CPU, 10-core GPU, 16-core Neural Engine and 153GB/s of memory bandwidth. With at least 16GB of unified memory, Thunderbolt 4 and support for two external displays, it is capable of productivity, programming, photo editing and lighter video-production work.

When buying a used or open-box unit, confirm its unified memory and SSD configuration because neither can be upgraded later. Check the battery cycle count and maximum capacity, ensure Activation Lock and device management have been removed, and test the display, keyboard, trackpad, camera, speakers, ports and MagSafe cable. The power adapter is sold separately when new, so verify what the listing includes.
