Also for the brightness control of the screen? Is it possible to make it functional?

I see in clover configurator that setintelbacklight + setintelmaxbacklight both not selected. 

I tried to select them, however - it showed only black screen after reboot. so I recovered it and deselect it and not it boots normally again with apple logo etc.

I am still unable to change the brightness.

 

I replaced the files and copied to extensions. I also ran the permissions.sh

I see also many other kexts in the extensions folder that I copied there previously from the generic installation guide. could it be a problem?

 

When I run permissions.sh or sudo kextcache -i / I see the following errors:

I do - changing it manually in the settings works now.

However, the keyboard hotkey doesn't work (can it be mapped to fn?). Also, I am now suffering that the machine gets stuck sometimes (freeze for 5-7 seconds) since the changes in the EFI. Any idea why?

 

My display card is Intel HD 520 1536 MB graphics.

To make it clear. the audio hotkeys (fn) works (f2+f3), but not brightness (for some reason mapped to fn+f6, only decreasing brightness is mapped). Also the Trackstick Scrolling function doesn't work.

 

I tried to implement it via Karabiner:

No option for point devices / cursor move (seems like the trackpad is not detected although it works).

also it is unclear how to add the xml file.

 

UPDATE:

I just found out that the key maps are wrong. also, Karbiner was updated and the new version doesn't support xml anymore but only json. does anyone has this json file? or old version of karbiner? other solution to force the correct mapping for e7470?

 

I tried this converter but it doesn't work https://github.com/durka/karaconv/
