The MacBook 2015 Repairability Score: 1 out of 10 (10 is easiest to repair)

Proprietary pentalobe screws continue to make opening the device unnecessarily difficult, and new cable routing makes the procedure even trickier.

The USB-C port is secured by tri-wing screws, and buried under the display brackets, complicating replacement. Also, being the only port, it will experience more use and wear than a typical single-purpose port.

The battery assembly is entirely, and very solidly, glued into the lower case.

The Retina display is still a fused unit with no separate, protective glass. If the display needs replacing, it'll cost a pretty penny.

The processor, RAM, and flash memory are soldered to the logic board.
