A line of code in Apple's software could be the first sign of a new Mac Pro computer
"The data is identical to that of the late 2015 (iMac17,1 in the same file) so it may as well be a remnant of the new iMac, but the strange thing is that...there are too many USB 3 ports defined to fit on a MacBook (Pro) and Mac Mini. This and the fact that there is already support for newer graphics chips [baked] into El Capitan," writes Pike's Universum.
According to MacRumors, the new Mac Pro could feature upgraded internals across the board with a new Broadwell CPU, faster AMD graphics chips, faster memory and storage, and Thunderbolt 3.
Prior to the redesigned Mac Pro in 2013, Apple's power users were left out in the cold for for almost three years which, when you need the very latest hardware on its release date, is a very long time.
