The macbook pro works very well. In very good condition. Have OSX Yosemite installed. Upgraded the memory to 8Gb. It has dual graphics processor in it, a intel HD graphics for low performance and a AMD Radeon HD 6490M Graphics for higher performance. I have also installed office 2011 and a program for you to switch manually to either of the graphics. Any other questions feel free to ask. NO LOW BALLERS NO SHIPPING NO PAYPAL.
