Hi guys I saw a nice offer for a macbook pro 15 inch ! http://www.everymac.com/systems/app...-15-early-2011-unibody-thunderbolt-specs.html I have got some questions for you guys : - Is this a reliable model ? What should i look for in terms of problem for this specific model ? - How would you proceed when going to see the buyer in a coffee shop ? Should i perform a Apple hardware test ? If so how ? Thanks guys !
