2.2 GHz Quad-Core Intel Core i7, 16 GB of RAM, 256 GB flash storage, integrated GPU, $1999.It shipped in two configurations, both with 16 GB of RAM, of which the high-end model shipped with a discrete GPU: The only changes were a faster discrete graphics chipset in the high-end model, and the inclusion of a 'Force Touch' trackpad, which used haptic feedback to simulate clicks rather than a using physical button and could measure and respond to click strength. Introduced in May 2015, the MacBook Pro (Retina, 15-inch, Mid 2015) replaced the MacBook Pro (Retina, 15-inch, Mid 2014). A single 3.5mm jack could be used for analog or optical audio out, or analog audio in. A 128 MB of 'Crystalwell' embedded DRAM served as both a Level 4 cache for the CPU and a cache for the integrated graphics chipset.

Actual usage varied with graphics load, resulting in slightly less RAM available for system use. Though reported as 1 GB, this was actually a minimum. The MacBook Pro's integrated graphics chipset used a portion of main memory as VRAM.
