Apple’s new 15 inch Retina MacBook Pro is the latest Apple device to support the 27 inch 5K display of Dell.¬†Apple initially released OS X 10.10.3 in April with support for the dual-cable 5K monitor on the Retina 5K iMac in 2013 Mac pro, but no note books supported the display at the time.

Dell’s dual-cable 5K display requires more bandwidth than is currently supported over a current single DisplayPort cable, so it uses a dual-cable solution that takes up two Thunderbolt ports on a Mac. The availability of Intel’s Sky lake platform with Display Port 1.3 support later this year will enable Apple to update Macs with support for external 5K displays that function over a single cable, at which point the company could theoretically release a 5K Thunderbolt Display.

The support document also lists the high-end 15-inch Retina MacBook Pro as capable of driving most single-stream 4K displays (4,096-by-2,160) at 60Hz on OS X 10.10.3, becoming the first notebook to support single-stream 4K displays alongside the Mac Pro (Late 2013) and iMac (Retina 5K, 27-inch, Late 2014 and later).

Note that this requires the version of the 15-inch MacBook Pro with the AMD Radeon R9 M370X. That graphics chip is also required to operate Single-Stream 4K displays with a resolution of 4096 x 2160 at 60 Hz. Apple’s new Mac book pro launched earlier this month¬†features the new Force Touch trackpad, along with faster flash storage, longer battery life, and the option for the R9 M370X.
