In a rather curt statement on its support site, the Mac maker wrote: "If your 15-inch MacBook Pro emits a high-pitched buzzing sound, please contact AppleCare for service." Apple offered no other details.
The Cupertino, Calif.-based company has been scurrying to mend a handful of minor issues reported with its new MacBook product lines, the the first of its consumer and professional notebooks to use chips and underlying technology from Intel Corp.
Despite the minor hiccups, Apple last quarter generated $1.16B in notebook sales, shipping nearly 800,000 units. The company said the notebook unit total consisted of a primary mix of MacBook and MacBook Pro models, and to a lesser extent, PowerBook G4s that remained in inventory.
Of all the models, Apple's consumer oriented Intel MacBook has emerged as a top seller. Although the company said it shipped a "significant number" of MacBooks in June, it still exited its recent fiscal quarter without enough supply to meet demand.
Earlier this week, the Mac maker admitted there is a problem with some of its white MacBooks where the computer casing may exhibit signs of premature discoloration.
