MacBook Air (15-inch, M4, 2025)
The MacBook Air (15-inch, M4, 2025) combines a spacious 15.3-inch Liquid Retina display with the performance and efficiency of Apple’s M4 chip. Its large screen gives documents, spreadsheets, timelines and multitasking layouts more room while retaining the thin, fanless design associated with MacBook Air.
With a 10-core CPU, 10-core GPU and at least 16GB of unified memory, this model is well suited to productivity, study, programming, photo editing and everyday creative work. It also supports up to two external 6K displays, making it considerably more flexible as a desktop workstation than earlier MacBook Air generations.
When buying a used or open-box MacBook Air, check its battery health, charging operation, display condition, keyboard, trackpad, speakers and both Thunderbolt ports. Confirm that Activation Lock and organisational device management have been removed, and verify the memory and SSD capacity because neither can be upgraded after purchase.
