Good afternoon, as you will see I am new in this forum, this is my second macbook is 1 year and a half, the previous one was stolen in a robbery but good since I updated MacOs Sierra after some time began to have graphic problems, which I do not tell Os, I tried to install the captain and I followed the problem. We started with a black screen that was solved closing the lid, waiting for the light to turn off of the apple like a freeze We continue with a shower of colors without being able to see anything of pink and violet colors that range, which from where the mouse is to his right and downwards was clouded with this rain. If the mouse was far below the screen you could see the rest but if it went to the upper left the screen with the rain. To all this, I found that if I demand graphic level it is solved .. WHAT? If, for example at this moment I have to have a video of youtube running in the background in the browser to be able to use it, the same thing happened to me if I play Legue of legends I can play quiet but when I leave PUM the problem. I uploaded this video but it just did not work when I closed the lid An other video And sorry for my English is that I am Argentine and I had to use the translator Thanks you! Gracias!
