Dell 5590 (RWFK9) High Sierra


Recommended Posts

Hello. I need your help for my new laptop.

The CPU is intel i5-7300U and Video is intel HD 620

Actually I have installed Sierra 10.13.6


Audio (except headphone connector)




Not working:
Touchpad (I can only move the mouse, use some gestures, but no way to click with left or right button)

Card Reader

Wi-FI (intel chipset, but I'll change a.s.a.p.)


Here is my EFI Folder and ioreg. Thanks in advance.

According to your IOREG, your I2C touchpad should be on TPD1, not TPD0. You'll need to rename it in SSDT-I2C.aml and in the Config file

For headphone, your ALC256 requires codecCommander in /L/E and SSDT-ALC256.aml.

Card Reader has little to no support. See this thread

Usually touchpad preference won't load if your Battery Status is not working, please confirm.

For now try this. Add the *.aml files to Patched folder and replace the Config file, I made a little modification.

If audio still not work, you might want to try moving CodecCommander to /L/E

Repair permissions and rebuild cache
