This is a used laptop in moderate cosmetic condition with signs of normal use (scrapes, scratches, scuffs, etc). There is a crack on the left side that extends onto the keyboard surface.

Please examine photos carefully.

High Sierra has been freshly installed. This is the most recent version of OS X that is officially supported on this laptop.

All of the built-in Apple hardware diagnostics have passed. 

Everything has been thoroughly tested and guaranteed to be fully functional (unless otherwise specified in this listing).

The battery is in good condition. OS X System Profiler reports a maximum charge capacity of 4,208 mAh and 549 charge cycles. However, no testing has been performed to assess actual usable battery life or discharge rate.
