Background and Identification
The MacBook Pro 13" Mid 2012 Unibody was released in June of 2012.
The Mid 2012 model, as with the models from 2011, has a case that is composed of a single block of aluminum, following the same process of the MacBook Unibody and the MacBook Pro 17" Unibody.
Over the years, it has been disputed as to how much RAM this particular laptop could support. Some third parties have determined that this MacBook can support up to 16GB of RAM but others have claimed that this laptop can only support up to 8GB. However, despite what many people thought about this laptop only being able to support 8GB of RAM, it is proven that this MacBook can, and is perfectly capable of, supporting up to a maximum of 16GB of SODIMM DDR3 RAM at 1600MHz.
