This Mac still features all of the ports. Many criticized the 2016 Macbook Pro models due to only having USB type C ports.

In addition, this Macbook Pro Mid 2015 model has a backlit keyboard, a “no button” glass “inertial” multi-touch / force-touch trackpad, a “MagSafe 2” power adapter, and an internal, sealed battery that provides an Apple estimated 8 hours of battery life.

Storage

Apple Macbook Pro MJLT2LL/A comes equipped stock with a 512GB PCIe SSD. This Mac can be upgraded all the way to 1TB SSDs. The new SSUBX SSD doubles the speeds of previous generation SSDs.

 

 

Screen Size and Resolution

The display is the same 15.4-inch 2880×1800 display Apple has used in all the Retina MacBook Pros, and it still looks great. It’s nice and sharp and has good-looking colors and great viewing angles. The best part is when you are just using the internal display, the OS X UI and all its animations and transitions run fairly smoothly on the GPU resulting in spectacular graphics display.
