Quanta Computer has begun volume production of the new 12-inch MacBook Air for Apple, paving the way for Apple to launch the device in the first quarter of 2015, according to sources in Taiwan. Quanta has stepped up efforts to recruit more workers in order to ramp up the production, Digitimes.com reports.

Quanta is also expected to be the maker of the Apple Watch.

The new MacBook Air, which is expected to come with a 12-inch Retina screen, is likely to replace the existing 11-inch MacBook Air, while the 13-inch MacBook Air will also remain available.
