Hi, My Macbook Pro from 2009 is starting to have some performance problems so I've been looking for a substitute. I want to switch to an Imac but I can only afford the 1.4Ghz 21.5" one, which from what I have read its quite overpriced if one considers its low performance vis-a-vis other models. I've been searching for second hand options in my area and found one that is quite interesting. It's a 2.7Ghz 21.5" Imac (late-2013), 8 Go 1600 MHz DDR3, bought on February 2015. The price is 1200 CAD$ and includes apple care until February 2018. It's exactly what I was looking for so I'm quite excited, and the price seems to be Ok, considering that new it would be around 2000CAD$ (apple care and taxes included). I've never bought a second hand mac before, so would like to ask the community here for advice on what should I check or ask the current owner about before considering buying it? Thanks!
