Me too!
This has happened to me twice. I sent TWO back...for the backlighting issue (plus the first one that was DENTED in shipping). I have had it for a bit. The customer service was great. But for TWO having the same issue... for 3 grand, this is unacceptable! It was over the last three weeks. So, maybe there IS a crappy batch? Mine was CTO from china. 17", anti-glare screen. I wonder if that is the issue, the antiglare screen, less solid/strong?!?!? What do you all think? So frustrating for a life long APPLE supporter/user. 😡
