My Mac Book Pro is now stuck after Apple logo screen on a grey screen and after hours of search I found the problem is in my graphic card (this issue happen after updating to High Sierra).
So I need to disable the second VGA
I tried with
/sbin/fsck -fy / /sbin/mount -uw / mkdir /Disabled_System_Library_Extensions cd /Disabled_System_Library_Extensions mv /System/Library/Extensions/ATI* . mv /System/Library/Extensions/AMD* . touch /System/Library/Extensions exit
but I got an error :
operation not permitted
any idea to fix this or at least disable SIP ?
I am not able to boot to any GUI neither by safe mode boot nor verbose mode or even recovery mode, so I need to do it via terminal
I am only able to boot via single user mode
