The most recent Lion update features some important clues giving Mac lovers hope for high-resolution devices. Apple has included into OSX 10.7.4 an icon for the TextEdit app, specially built for Retina Display.
The previous version of OSX featured a TextEdit icon with a maximum resolution of 512 x 512 pixels, and now the resolution has increased to 1,024 x 1,024 pixels. As expected, the icon's file size has jumped significantly, from 209KB to 1.7MB.
The latest Lion update also features icons with bigger file sizes, compared to the previous version. AppleInsider reported that the Address Book icon is now 48 KB, compared to the previous 279KB and Dashboard's icon file size is now 100KB larger than that in OSX 10.7.4.
None of these apps, however, haven been updated for the Retina Display. This is not the first time Apple has hinted to a Mac lineup featuring Retina Display.
Since OS X 10.7 Lion was in beta mode, tech writers and developers noticed that both the App Store and Launch Pad have icons of 1,024 x 1,024 pixels. Small upgrades were made as far back as OS X 10.7.3, when Apple added other high-resolution elements into the user interface.
As analysts have previously pointed out, the further deployment of Retina Display, currently featured in the new iPad and the latest iPhones, could have a great impact on the industry and even on the web.
