Instruction manual update

My third assignment for this semester is an instructional manual. So basically we have to write about a topic that we are familiar with and write it in a way so another can learn how to do it in a step by step way. The topic I chose was how to upgrade the hard drive on a MacBook Pro Late 2011 laptop. It is a topic that I am very familiar with because I’ve done that so many time to my computer and others computers too.
Therefore it was a straight up process for me.
