MacBook Pro 15" Unibody Mid 2012 Repairability Score: 7 out of 10 (10 is easiest to repair).

Easily removable bottom panel and readily accessible battery, optical drive, hard drive, fans, and RAM.

Standard screws were used for all components, save for the battery.

Significant amounts of thermal paste may be a pain in later repairs.

Tri-wing screws on the battery require a specialty driver that an average user may not have.

LCD replacement is still the most difficult repair. Inexperienced (and even experienced) technicians may shatter the glass during repair.
