The company is preparing its marketing, sales and retail teams for the debut, according to Gurmans sources, and its letting inventory of the existing models wind down. The M4 MacBook Air is expected to come in two sizes, 13-inch and 15-inch, like the previous model.Apple introduced the M3 MacBook Air last March, and unveiled its new M4 chip a few months later, bringing that first to the iPad Pro. In October, it refreshed the iMac, Mac mini and MacBook Pros with the M4 family of chips. The MacBook Air is now due for its turn.
