The 15-inch MacBook Air with the M4 chip is Apple's largest fanless laptop, with 16GB of unified memory as standard and a 15.3-inch Liquid Retina display. It adds a 12MP Center Stage camera, a six-speaker sound system, MagSafe charging and Touch ID, and Apple rates battery life at up to 18 hours. It suits people who want a big screen for writing, spreadsheets and video calls without a fan or a heavy chassis. Against the 13-inch Air it offers more screen and speakers for the same chip; against the MacBook Pro it gives up the brighter mini-LED display, more ports and sustained heavy-load performance.
