Hi guys, The macbook pro has been my dream PC for so many years... This month is the month, where I'm gonna purchase one. Currently looking into craiglists, and one cost 1650$ CAD, early 2013 (the GEFORCE 650M one) has 260 charging cycle & warranty until october 2015. Another one is 1275$ , middle 2012 model and has the same specs, the guy claims the retina was changed in June 2015& battery is original and has 60 battery cycle. Would like to know which to choose and how to make sure there is no icloud lock... Thanks guys !
