I want to know How to remap my keyboard to brightness control keys. I have a Lenovo Z70-80 laptop with Core i7-5500 and my graphics card is Intel HD Graphics 5500 running macOS HS 10.13.6 I followed the RebahMan Guide Patching DSDT/SSDT for LAPTOP backlight control and in a special part it says that if the VoodooPS2Controller.kext doesn't works correctly with your own keyboard We can custom it. Then, I follow the next steps: Determining EC query methods: - install ACPIDebug.kext: https://github.com/RehabMan/OS-X-ACPI-Debug - I installed on S/L/E - add the ACPIDebug repo to MaciASL "Sources" per README - It is on sources by default - apply ""Add DSDT Debug Methods" - I added this to my DSDT - apply "Instrument EC Queries" - I added this to my DSDT - I added debug.txt too - In Readme debug says 3 steps, but this final step: Third, add code to your DSDT to where you wish to cause trace messages to system.log (call \RMDT.PUSH). - I don't understand this part or what code I should add. Please I need support with this special part. - I added additionally ioio binary file to /usr/bin/ , like it says in the guide - reboot - monitor system.log as you press your brightness keys After I reboot I pressed all FN keys, one by one and with combinations with Fn+ key but nothing. My DSDT. aml patched file is in /Clover/ACPI/patched and like it says in guide the system.log is created in root, I can understand is the same folder where is my DSDT, after pressed the keys. It doesn't appear anything file. I don't know maybe I made a mistake in the process. PD. 01- I attached my DSDT patched. 02. I get some keys code with the app KeyCodes running over macOS and I tried the same with my microsoft keyboard in my hackintosh Pc and codes are the same. I attached all pictures about it. Please help me with the solution. Thanks in advance Finally I solved my issue here
