    HiDPI Retina Images in Mountain Lion, Already Functional in OS X Lion

    ArsTechnica reports on the discovery of Retina-sized artwork in OS X Mountain Lion's.

    A source with access to the latest Mountain Lion preview alerted Ars that double-sized graphics have popped up in some unexpected places, once again suggesting that Apple may be close to releasing MacBooks with high pixel-density screens.

    We'd previously spotted these same Retina-sized graphics in the Lion beta of Apple's new Messages application.

    As well, we've found in our testing that Apple's HiDPI mode in Lion is already fully functional and will use the Retina assets appropriately. These screens show the Lion Messages app running in HiDPI mode.



    HiDPI mode on OS X 10.7. Left: Retina enabled, Right: Non-Retina



    The left image shows that Lion with HiDPI mode enabled uses the full resolution Retina artwork from the Messages app to improve the pixel sharpness of the images. When the Retina assets are selectively removed from the app (right), you can see it fall back to the normal non-Retina images bundled.

    Users will be able to test this themselves to full effect when Air Display is updated to support Mac HiDPI mode on the new iPad. Apple's Messages Beta for Lion is one of the few Mac applications that are already Retina-enabled to a large degree. Some elements, such as font rendering will automatically scale upwards as it does on the iPad.

    Signs in Mountain Lion point to "retina" display MacBooks sooner than later

    A new clue found within in the latest developer release of OS X 10.8 (Mountain Lion) suggests that 2012 may bring us the "summer of retina display Macs." A source with access to the latest Mountain Lion preview alerted Ars that double-sized graphics have popped up in some unexpected places, once again suggesting that Apple may be close to releasing MacBooks with high pixel-density screens.

    One example comes from Messages, Apple's replacement for iChat. While using the app under the second developer preview of Mountain Lion, some icons are erroneously displaying 2x resolution art. In the image below, the "audio chat" icon is a 2x version instead of the standard 1x version, according to our source.




    Note the double-sized icon popping out of where a standard size icon should fit.


    "I would interpret it to mean that Retina [MacBook] is close; perhaps concurrent with the release of OS X 10.8," our source said.

    As we noted late last year, the tech to create suitably pixel-dense displays already exists, and the ability to adapt OS X's UI to those displays is already present in the form of "HiDPI" display modes. Apple has already been incorporating 2x UI elements such as cursors and other objects into recent releases of OS X 10.7 (Lion), as well.

    With Mountain Lion scheduled to be released sometime this summer and Intel's next-generation Ivy Bridge processors expected to have wide availability at about the same time, we agree that this latest evidence points toward Apple unveiling MacBook Pros and possible MacBook Airs with "retina" displays in the next few months.
