Was curious about whether Apple plans to support 60Hz 4K resolutions for the haswell Macbook Pros. Hardware wise, Intel has said that Iris/Iris Pro should be able to handle this and the bandwidth is there with the inclusion of displayport 1.2 over thunderbolt 2. However, Apple lists only 2560x1600 as supported over displayport on their spec page for these machines. Given the hardware support for 4K over thunderbolt 2, I imagined that Apple would add support into OS X for the 2013 Macbook Pros once the Mac Pros were released. However, now that Apple has released the Mac Pros, it seems like this might not be the case. Under the configuration page for the new Mac Pros it says that Compatibility: 4K DisplayPort operation only compatible with the new Mac Pro (Late 2013). 4K HDMI operation compatible with MacBook Pro (Late 2013) and the new Mac Pro (Late 2013). To me, this says that Apple does NOT plan on enabling 60Hz 4K over thunderbolt for the late 2013 Macbook Pros. What do you all think?
