Apple could release its next iPad equipped with the Mac OS X operating system in addition to the iOS, if rumours are to be believed.

The 12.9-in tablet, due for release in 2015, is expected to be unveiled on 16 October in a press conference that will also reveal a new line of iMacs, according to Re/Code.

A source in Apple’s supply chain told Digitimes that it is developing two tablet prototypes – one a regular tablet, while another will be integrated with both operating systems.

That means that it could be releasing a so-called iPad Pro with full desktop capabilities, as well as an iPad Air 2 – an upgrade on its 2013 offering.

The latter thin and lightweight device is expected to have Touch ID, more RAM, and Apple’s iOS 8 software - but could also simply be called iPad 6.

It has also been suggested that a new colour of gold could be available for the next generation of iPad.
