black bar at the bottom screen
So I got this weird black bar that appears on the bottom of the bar only after using the laptop for a period of time, and it just getting higher since the first time it appeared!
A1706/EMC 3071—于2017年6月上市，这台13''MacBook Pro以可升级至3.5Ghz酷睿i7动态超频至4.0GHz的Kaby Lake处理器为特征。
The backlight diffuser sheets are coming loose from the back side of the panel at the bottom so the backlight is not illuminating that section. You’ll need a new display assembly. There is nothing repairable here as the display is sealed tightly.
You’ll need to bring it into an Apple Store or authorized service center as this should be covered under a warranty exception! If you have AppleCare+ you’re golden!
Please explain more fully about the "warranty exception" This "bug" sounds like it is totally of Apple's making. I have this problem also and was told by tech support I would need to send it to an Apple service center, (as I am too remote on the island of Molokai, Hawaii to take it too an Apple store), with $500(!!) up-front, none of which would probably get credited back to me. My MacBook Air isn't even 4 years old, and I very painfully paid a bundle for it. I had my previous Dell desktop for nearly 10(!!) years. It had its problems here and there, but especially by allowing me to extend my service contract 3 times over, I was able to keep it going for that long of a time. This is my first Apple product---and it could very well be my last☹️.
I had a similar problem however the lines were appearing at the top. However I noticed a few things it started happening on my MacBook Pro 2017 13” model after the Mojave update also it only happens when I have a black color themed application or a movie with black bars at the top and bottom is played for existing amount of time.
The solution I found was shut down the Mac for about an hour or switch to an application which has a complete white or any other color Interface for about an hour then it slowly goes away. Further, I took a screenshot shot on that the normal color apprears. It's an interesting issue.
I am not sure what the underlying cause is I have a feeling it could be something to do with both hardware and software.
