New icons grow up to double in size
Yesterday's OS X 10.7.4 update also brought with it more preparation for Macs equipped with Retina displays, observes AppleInsider. One example is the icon for TextEdit, which was previously a 209KB image measuring 512x512, but now takes up 1.7MB, and has doubled in resolution to 1024x1024. Other icons have grown in size without doubling in resolution; these include ones for Address Book (from 279KB to 484KB) and Dashboard (from 130KB to 226KB).
Apple has been quietly upgrading the graphics in Lion for some time. Some of the icons in the Lion beta, in fact, already measured 1024x1024. The v10.7.3 update upgraded different elements of the interface, such as cursors.
Macs are now the only major category of Apple products without any Retina displays. The iPhone, iPad, and iPod touch all have Retina models, even if some still lack the technology. The main obstacle for Macs is likely cost, since screensizes can range anywhere from 11 to 27 inches. Some developers, though, may also have to scale up their art assets to avoid pixelation.
