I've never, in 10+ years of MacBooks, had to replace an adapter due to fraying. I suspect it's because I don't yank the cable out (instead grabbing the plug), but more importantly, because I don't use the cable wraps included. Just a quick over-under coil, tossed in the bag, and I'm good to go. I still use the adapter that came with my 2006 MacBook, having added one of the plug converters for the Retina laptops.
