A finding earlier this month by OSXDaily has generated some speculation about Apple's plans for "Retina" display Macs. The Mac OS X Lion Developer Preview 2 released in late March included an ultra-high resolution version of the background desktop image at a resolution of 3200x2000. A few observers noted that this is higher than any Apple display has ever supported, generating speculation that Apple is preparing for "Retina" display Macs in the near future.
We had previously reported that Mac OS X Lion has made some under-the-hood changes opening the door to such super-high resolution displays.
Taking cues from iOS, Apple has reportedly built in support for what it calls "HiDPI display modes". These HiDPI modes allow developers to supply 2x-enlarged images to support double-high resolution displays. Like the iPhone 4's Retina Display, this means that user interface elements will remain the same size, but everything will be twice the resolution and therefore twice as detailed.Now, MacMagazine.com.br has found that Apple is already starting to include other super high resolution artwork in Lion. They found several icons stored as 1024x1024 sizes, up from a previous maximum of 512x512.

Of course, this support for super high resolution displays is only the first step, but suggests Apple is planning ahead when the hardware becomes available.
