Just hours after the release of OS X 10.7.4, evidence has been uncovered that points towards Retina display Macs in the future. As discovered by AppleInsider, the resolution of the TextEdit icon in OS X 10.7.4 has doubled, up to 1,024-by-1,024 pixels from 512-by-512 pixels.
The doubling of pixels in application icons suggest that Apple is planning to introduce new Macs with ultra-high-resolution screens, much like the Retina displays currently found on the iPhone, iPad and iPod touch lineup. Apple’s new iPad, released in March, packs 3.1 million pixels onto its 9.7-inch display, giving it a higher resolution than a high-definition 1080p television.
Numerous other applications, including the Mac App Store and Launchpad, have already had 1,024-by-1,024 pixel icons since beta versions of OS X Lion. The developer preview of OS X Mountain Lion, slated for release this summer, also contains several different pixel dense graphics. Intel has confirmed that its Ivy Bridge processors, which should power new Macs within the next few months, will support machines with resolutions up to 4,096-by-4,096 pixels.
