Hi everyone! I have a problem and I am not sure whats my problem.. So I could use my hackintosh for months without any problem but now, at booting up the system my brightnes display goes under zero and of course I cant see nothing on my screen. It is fully booting up, because sometimes the screen flashing up for a second.. And at the booting up Apple logo can see how my display turns the brighntess under zero.. I am using right know, 10.12.5 ( but maybe in the night just updated my system to 10.12.6.., I am not sure:/ ) I have HP 2570p, with Intel HD 4000, before it i used intelbacklight.kext to get the full brightness level and before it, at the booting logo the display goes to the maximum level of the brightness, but now It is goes under zero.. Maybe do you know any method to get back the maximum britghness level at booting up? Or I have to rebuild my whole system? Pleease help me, I should work but I am on Holiday and I have not here the bootable Usb installer.:/
