So I bought a Refurbished 2011 MBP from Apple in 2012 and should have done my homework as mine died to Radeongate. apple replaced it... after the threat of lawsuits hovered over them. I need a second machine now. Wont need to do the same intense graphics use on the machine I'm looking to buy now. considering either a refurb or going with a Windows 10 laptop via Costco. Wondering if there's been any large scale problems with the late 2013 models. Looking at a dual core 2.4GHz, 13.3" rMBP. Thanks.
