                  • Inexpensive
                  • Mac Compatable
                  • Simple to install


                    Best Uses

                      I installed this in my 13" Late 2011 MacBook Pro. The installation was increadibly simple and the added capability it facilitates is certainly worth the money. Not only did the boost in RAM help the computer cope with audio production, but I was very pleased that the computer, recognising the extra RAM automatically designated more virtual memory for the integrated graphics. I'm not much of a gamer but it has meant that I can increase the graphics settings on StarCraft 2.
