My MacBook Pro Mid 2012 screen is black and then just vertical stripes (like a glitch). Why and how do I solve this?
This is a common problem with 2012-2013 Macbook pro's, and is caused by the connection to the GPU card cracking. Apple is offering a repair program where they will fix this for free. If you have an Apple Store near you, I would suggest taking it in and having them fix it.
