My laptop is Hp ab522tx(https://support.hp.com/in-en/document/c04863397)
HP Pavilion Notebook - 15-ab522tx
Intel® Core™ i5-6200U with Intel® HD Graphics 520 (2.3 GHz, 3 MB cache, 2 cores)
8 GB DDR3L-1600 SDRAM (1 x 8 GB)
NVIDIA GeForce 940M (4 GB DDR3L dedicated)
I made bootable USB of high sierra. While installing it in verbose mode, I get a blank black screen. Mostly its graphics problem with the kext.
please help guys.
Hello everyone, I have an Asus gl502vmk (i7 kabylake + GTX 1060 6 gb) laptop and I tried all the patches/kexts to get the brightness with fn keys/touchpad (I2C ELAN 1200 works with VooDoo I2C kext v1.0 but no gestures/preference pane)/Keyboard backlight to work but no success so far, any help would be appreciated, thanks in advance.
Battery status now works, thanks to @RehabMan turned out to be incorrect SMBIOS (used iMac instead of Mbp) lol, but it drains crazy fast (~1.5 - 2 hours while on standby (all apps quited!), on windows 10 it lasts 4 - 5 hours, and on linux it lasts 6 ~ 7 hours!)
And with VoodooI2C v2.0.1 + VoodooI2CHID kext and patched DSDT, the touchpad is now detected in the sys pref pane but still no input.
Sound works with VoodooHDA v2.9.1, but the only issue is that the jack sense isn't working (the output device doesn't auto switch to headphone when connected)
[EDIT 2] (11/04/2018)
The system brightness now works thanks to @onejay09 but I have no brightness slider, and there are 4 extra brightness levels (brightness stops increasing after 12 levels) and the brightness keys are not mapped correctly, plus the brightness decreases when I plug in the ac adapter, then increases if I unplug it???, the brightness level isn't also saved after reboot.
battery still drains crazy fast (~1.5 - 2 hours, even with brightness at 50%, so apparently it is a power management issue).
and I also have shutdowns while in sleep mode (I tried darkwake=10 and darkwake-0 and darkwake=no)

Please help me with this 10.9.5 system. Motherboard: Gigabyte 965p-s3 rev3.3, gpu: Ati Radeon HD6450 (dvi/hdmi/vga).
Using any of the 3 ports on the 6450 (dvi, hdmi, vga), I see all the white letters on black background during boot but when they complete and it's time for the graphics to start I get a black screen and sometimes a restart after that. Using Clover 4411. Is there any way to get past this?
