    Hi all

    I have a Mac Retina 5K, 27-inch, Late 2015 model running OS 10.12.3 (16D32)

    Every time I wake it up from sleep not only does it take quite a long time but the black screen shows a narrow pixilated colored band across the top of the screen. Has this come up with anyone before and if so whats the fix?

    Thanks
