Hello everyone,

I have a problem in the control of brightness, it is present in the parameters, but it has no effect.

I put the file "SSDT-PNLFCFL.aml" in / Acpi / patched, as well as the parameter "enable-cfl-backlight-fix" in the file config.plist

Thank you very much if someone can solve the problem, because the brightness is fixed at 100% and the battery discharges very quickly.

Hi
I am planning to buy the same laptop (XPS 7590, i7, 512GB, 16GB RAM). Have you successfully installed Hackintosh on the laptop? What all is working fine and what issues are you facing?

Thank you,

I try with the link you give me, now the CPU goes down to 0.80Ghz (the battery is longer and the fans are always off), but still the problem with the brightness control.

The trapckap works very well too.

If anyone can identify the problem please.
