TechnoBuffalo reports that “the code was first spotted by French news outlet Consomac and specifically references support for a computer with a native resolution of 4096 x 2304.”
Suspicion is a go as we think what Apple’s next move with this code will be. My suspicion is that Apple will release the 4K iMac with a lower price than it’s 5K iMac was at it’s release and probably a refresh of the 5K desktop computer.
If these rumors are true, we’ll be seeing the release of this new computer in the fall, around the same time the final version of OS X El Capitan is released to the public. Typically, Apple likes to release new hardware and show it off with new software as well.
