Retina display coating
I'm experiencing issues with my retina display coating wearing off on my macbook pro. It first started a year after I purchased it but I thought my screen was just dirty. A friend has recently brought to my attention that it's actually a fault with the retina display. My laptop works completely fine, it's just the screen coating is eating away. My warranty has expired. What should I do?
MacBook Pro with Retina display, macOS Sierra (10.12.6)
