Apple is reportedly set to kick-off mass production of a new 12-inch MacBook Air during the first quarter (Q1) of 2015, following its pilot production in late 2014, according to sources from the ‘upstream supply chain’.

Apple is also starting production of its smartwatch, with its suppliers already starting their supplies of related components.

Powered by Intel’s Broadwell processors, Apple’s new MacBook Air comes with a new chassis design that trims down overall thickness and weight.

Furthermore, sources told Digitimes that the new MacBook Air is mainly targeted at the high-end market sector, with only limited shipments.

The new laptop will also replace USB ports with the reversible Type-C USB port, which was revealed this August by the USB 3.0 Promoter Group.

The iPhone maker is also planning to replace the MagSafe charging port, used on existing MacBook models with a new method to charge the device.
