Metal compatible?

After millions of searching videos and everything, i decided to just ask a question instead and give my overview of my macbook to find out if it is mac compatible or not?

OS X El Capitan Version 10.11.1

MacBook Pro (13-inch, Mid 2012)

Processor: 2.5 GHz Intel Core i5

Memory: 4 GB 1600 MHz DDR3

Graphics: Intel HD Graphics 4000 1536 MB

Please tell me if my mac is metal compatible and if it doesn't, why?
