If you have a working Brightness Slider and you might be using Brightness slider or manual hotkeys to control brightness then this guide may help you to use your Native hotkeys of laptop.
(All the Credits goes to @RehabMan For OS-X-ACPI-Debug Kext and DSDT Patches.)
This step assumes that you are using RehabMan's VoodooPS2Controller or Acidanthera's PS2Controller
Install the kext: https://github.com/RehabMan/OS-X-ACPI-Debug
Open MaciASL and click on patch.(Add rehab man repo)
Apply "Add DSDT Debug Methods" and "Instrument EC Queries" that are under Brightness Fix.
Save the DSDT and restart
Look in Syslog as you press the key corresponding to brightness to determine which _QXX methods handle the keys
(UPDATE: From Sierra Apple changed logging process. So you won't find ACPIdebug result using syslog command. Instead use following command )
log show --last 5 | grep ACPIDebug
6. Then patch DSDT:
into method label _Q1D replace_content
// Brightness Down\n
into method label _Q1C replace_content
// Brightness Up\n
Change the variable _Q1D/_Q1C as per the log.
7. Try compiling and check if it generates errors 8. If it does, then change the PS2M to PS2X according to the one found in your DSDT 9. Save and place the compiled DSDT. 10. Now you should see that you have your corresponding keys to change your brightness

Greetings from Brazil! I'm running macOS Catalina 10.15.2 on my Lenovo Ideapad 300-15ISK laptop. Everything works smoothly, except decent battery management, so I decided to rebuild my DSDT from scratch, so I can patch it properly. It was a bit messy to start with.
I followed Rehabman's guide (to the letter) posted on tonymacx86. However, I keep getting a compile error, no warnings at all, just 'syntax error, unexpected PARSEOP_ARG1'. Please refer to attached PNG image and .dsl file.
I've searched endlessly for a solution, but can't fix it no matter what I try. Any ideas on how to fix this issue? I really appreciate your time and help.
Recently switched to OC from Clover where I had a Mald0n created DSDT in my patched folder
Bringing Device Objects across via SSDT and after much trial and error had some success with SBUS children by editing this SSDT https://raw.githubusercontent.com/acidanthera/OpenCorePkg/master/Docs/AcpiSamples/SSDT-SBUS-MCHC.dsl
Can anyone let me know what this (MKY0) actually does?
Hi Guys I have been trying to get my hackintosh to work using High Sierra... My Build is:--
Asus Z87-K Mother board
Intel i5 processor
8 gig of Memory
Nvidia Geforce GT 730 4gb DDR3
500gb SSD hard drive
I can get it up and running if I take Graphics card out and use Internal graphics, but when I have my graphics card in the only way I can get it to work is to use boot flag nv_disabe=1 .... and the graphics are rubbish..... I am trying to get it working by creating my own DSDT file..
what I have tried is to download and used RwPortableX64V1.7 to extract 4 SSDT.aml files and one DSDT.aml ... I was looking on this forum for any clues what to do next
but I a am afraid I am stuck... I have uploaded the files I extracted from RwPortableX64V1.7
