The MacBook Air Retina 12 inch was eagerly awaited during the events of the Cupertino group at the end of the year, without ever showing up, postponing a potential announcement to 2015. The site 9to5Mac claims to have obtained details that suggest a serious redesign of its design.
The future device would thus have a general overall dimensions close to the 11 inch model but with a very refined design (which would give it the code name MacBook Stealth) and a high resolution display leaving less space on the sides. The unibody metal shell would be much thinner and would have tightened the keyboard keys while keeping the same layout.
The trackpad would occupy a larger space, extending from the keyboard to the edge of the device. With such a thin format, Apple would have eliminated most of the connectors by keeping only a headphone jack and a port USB Type-C (Reversible USB).
This single port would advantageously replace the other usual connectors like the standard USB port, the Thunderbolt connector or even the MagSafe socket. It also suggests that the MacBook Air Retina 12 inches will be accompanied by a hub to connect various peripherals.
The device is expected to mid-2015, which may suggest a launch around the WWDC developer event in June. Mass production could however start this quarter.
