The rumoured 12-inch MacBook Air with Retina Display won't arrive until late 2014, at the earliest, according to reports on Friday.

According to Taiwan's Economic Daily, the higher-resolution option was scheduled to go on sale in Q3 of this year, but supply chain shortages mean production has been pushed back.

The report says a shortage of Intel's new Broadwell chips is to blame for holding up the process.

The 12-inch MacBook Air, which has been rumoured for well over a year now, is rumoured to have a refined design, new trackpad, a new battery layout as well as that hyped Retina Display.

On schedule

In better news for those seeking to add a MacBook Air to their gadget arsenal in the somewhat nearer future, the 2014 non-Retina 11-inch and 13-inch models are reportedly still on schedule.

Those devices will arrive in the third quarter, perhaps around the time of the iPhone 6 launch, according to reports.

Are you relying on Retina? Or will an updated standard model do? Let us know your thoughts below.
