I'd recommend you asking à tech friend to help you out. The basic concept is to switch from your MBP's graphics chipset to the integrate chipset. I am a tech guy and it took me a bit of digging to get it working. Now any time you have any problem with booting up simply reboot into single user mode type mount -uw / or /sbin/mount -uw /įor the command to move the kext file, you are moving the that file to the folder you previously created, aren't you? (The name is blacked out for privacy reasons) In your terminal you want to type #/bin/sh sudo nvram boot-args="-v" sudo nvram fa4ce28d-b62f-4c99-9cc3-6815686e30f9:gpu-power-prefs=%01%00%00%00 exit 0 sudo chmod a+x /iGPU-boot.sh Brightness keys should be working! HOW TO PREVENT FOR THE FUTUREĭONT FREAK OUT if you see a black box around it ITS TOTALLY NORMAL it should look like the picture attatched below mv /System/Library/Extensions/AMDRadeonX3000.kext /System/Library/Extensions/įorce the system to update its kextcache Touch /System/Library/Extensions/įor the final time type nvram fa4ce28d-b62f-4c99-9cc3-6815686e30f9:gpu-power-prefs=%01%00%00%00Įnable verbose boot mode nvram boot-args="-v"Īnd wait for it to start up. Next we are going to move only One offending kext out of the way. Mount -uw / or (/sbin/mount -uw /)Īnd make a kext-backup directory. You should see white text on black screen. On startup as soon as you see a white screen hold (Command+S) Into terminal type the following csrutil disable At the top you will see a tab called _Utilities._from that click terminal So after you get into recover mode your going to have to select language and than procede. You might have to hold it for 5+ minutes it depends how badly your GPU is damaged. Now type reboot and when you see the white screen hold command+r Now force shutdown by holding power and restart into single user mode (Cmd+s)* Now everything is reset (Dont worry you wont lose any files) than press Cmd+Option+p+r wait for two chimes. press leftshift+control_(NOT COMMAND)_option+power Start by resetting all hardware settings i.e your speakers, brightness, audio, everything. Hello there! I had the exact same problem and my solution would be to restart the whole procedure here's what i do. I'm going to attempt to reverse this process because my screen was dimmed to ~50% before I started. If you do this you'll lose the ability to adjust your display's brightness. So far so good, nothing has crashed yet.īUT! A warning to everyone.
Did everything with no errors but envidia Graphics card still enable and crashing my computer, any thoughts?
