Indeed a low price. For such a procedure: Watch entirely and listen to his comments on the built quality Apple sold us. But reballing the old chip is not the same as swapping the old chip out for a new one. Might effect the price. Concerning the chip in question: http://www.mactrast.com/2013/10/owners-early-2011-macbook-pro/ http://www.computerworlduk.com/it-v...-apple-fix-macbook-pro-graphics-woes-3537296/ Its pins might fit, but the chip model itself is no guarantee for success. You have to ask yourself: Where have you sourced the chip, is it "new" or salvaged? Tested to work? If the hack methods from here are not sufficient and there are no other problems apparent in your machine it might still be worth a shot. --- Post Merged, Jul 28, 2017 --- Way slow. I might try first to pacifist an installation. Or doing the install on an unaffected machine. But it's about a beta. Unless someone already confirms that there are notable improvements for the issues of this thread it' very low priority for me.
