Question, I'm thinking of buying a cheap used macbook pro. What would you suggest I buy for less than $400. I think a 15" would be ideal but not sure what model possibly something in the 2010+ year range. This would just be mostly for surfing the internet no major projects on it. I do like the older 17" models too for the large screen but I'm worried about upgrading to El Capitan because of the graphics card. I'm seeing the 17" laptops for $200. A 13" is def too small for my taste, but all in all I'm looking for something in the 15" screen range that can update to El Capitan without all of the boot.efi headaches. Thanks for looking.
