It is reported that the new MacBook Air thinner than existing models, performance is more prominent, will debut next year in Apple's WWDC (Developers Conference).
According to supply chain sources, the new MacBook Air is still in the design phase. It's said that the internal components will get a 'comprehensive upgrade' and that a similar appearance is to be expected.
The MacBook Air hasn't received a significant update in years so it's definitely due for an update. Based on the reported 13-inch and new 15-inch size, it's possible that Apple could discontinue the 11-inch model in favor of the new 12-inch MacBook.
Quanta will likely assemble the new MacBook Air. We'll let you know if any more details leak out. You can follow iClarified on Twitter, Facebook, Google+, or RSS for updates.
