Apple's new 15-inch MacBook Pro is the latest Apple device to support the 27-inch 5K display from Dell. As with the Retina iMac and Mac Pro, support for Dell's display requires the use of two Thunderbolt ports.
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 4096x2160 at 60Hz.
Apple's new MacBook Pro launched earlier this month. It features the new Force Touch trackpad, along with faster flash storage, longer battery life, and the option for the R9 M370X.
