I have a Macbook Pro Retina (had it for about 2 years). The charger has been playing up for a while and now it's not charging at all. I have tried EVERY 'fix' mentioned in Google so I started to resign myself to getting a new, extortionately priced charger. But then I saw all the 1 star reviews for these chargers and started to wonder if it was time for a return to W****ws. Any thoughts, anyone?
