Some updated UI elements in the latest version of OS X Lion hint at the possibility of higher-resolution, Retina display-like Macs. If you’re the kind of person that notices the resolution of your mouse pointer, you will have observed that the hovering icon in OS X 10.7.3 has been upgraded to a HiDPI resolution.
What does that mean? You could be able to get your grimy hands on a Retina display Mac in the near future.
It’s worth noting that Apple could have just gotten around to updating the icon resolutions for clean scaling with Lion’s Universal Access feature. Those with poor eyesight will benefit from having a mouse pointer that can remain at full resolution when zoomed in on fully. Gruber points out that some Mac Mini owners have seen their computers reboot into HiDPI mode when connected to a TV over HDMI. Apple has been implementing Retina display-like HiDPI elements into OS X for years, but more examples of hi-res UI elements are starting to surface.
A higher-res, 2880×1880 Mac is on the horizon, with a recent rumor suggesting that the product will come out in the second quarter of 2012. Based on typical product cycles, Apple’s entire Mac lineup is due for a refresh this year. We’ll see what happens.
