Start your Mac normally – Mac should use only Integrated Graphics Card now and it should boot always using integrated gpu. This will rebuild kexts cache which won’t contain AMD or ATI drivers kextsħ. Sudo kextcache -v 1 -m /System/Library/Caches//Startup/Extensions.mkext /System/Library/Extensions/

Sudo mv /System/Library/Extensions/AMD*.* /_temp move all AMD or ATI folders (files) to folder you created Reboot Mac and enter to the Console mode (Command + S before gray screen appear)Ĥ. Now you can follow the instruction from prevoius post.ġ. When it will do this QUICKLY use gfxCardStatus from pendrive you prepared to switch to Integrated GPU. Is highly possible your mac will bot using integrated GPU. It MUST bu turned on when its still hot.Ħ. After its turned off, QUICKLY remove your mac from bag/case and turn it on. Do something that will not allow fresh air to cool your mac – you will hear in few minutes that fans starting to spin crazy but still leave it in this state – to the moment when it will turn off automatically.ĥ. Let it in this state – close lid, and put your mac to your case, and even more put it to some bag. Turn on mac, leave it run to the moment when it will freeze on blue/gray/other screen.Ĥ. Your system files/drivers should be on right place.ģ. Make everything same with drivers like it was before your mac was broken. Download gfxCardStatus but max version 2.2.1. It means you CAN BOOT your broken mac and do some action to prevent using AMD or ATI gpu again.ġ. After reading hundreds of hundreds articles, blogs, forums looking for some more suitable solution i found one really interesting.īecause Macbook has built in option to automatically turn off the computer when its over heated and has (or looks it has) the mechanism to prevent to over heat again setting all or most of all option to minimum when user will turn it on again after it was automatically shut down, the macbook is ABLE TO BOOT using INTEGRATED GPU!!!
