Hi, a friend of mine has a 2010 MBP and since he bought it, has problems with the GPU, gfx seems to not work at all, ignoring his inputs when he selects just the iGPU. Has Apple something for this? There is any thing to do with it? This happens suddenly, just browsing the web. Another thing that usually happens is getting kernel panics when he opens apps like Premiere. There is a way to "disable"-"disconnect" the dGPU?
