I assumed that by purchasing refurbished I would receive a computer that had already been used but good to go. Definitely not the case. This computer is filled with hardware bugs. Keyboard doesn't work correctly, I am constantly getting double spaced even after adjusting settings.  It's SLOWER than my 2011 Macbook Pro- how is this possible?? I use this for photoshop and lightroom and batch editing 15 photos takes over 3 minutes. This should  be an  instantaneous thing.  The touch button on the top right  only works 50% of the time. I contacted the seller but they do not take any responsibility. They tell you to deal with Apple instead.
