Moderators Jake Lo Posted February 12, 2021 Moderators Share Posted February 12, 2021 Replace with this Config. Added proper patches to your config to add the brightness Fn keys config.plist.zip Link to comment Share on other sites More sharing options...
Mihari Oyama Posted February 12, 2021 Author Share Posted February 12, 2021 i have replaced the config, but seem not work... but i think remap the brightness key needs to use plist in voodoops2keyboard, not use the BRT6 Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted February 12, 2021 Moderators Share Posted February 12, 2021 What's in DSDT? What patches does it have? Can it be removed? Try this SSDT-XOSI SSDT-XOSI.aml.zip Link to comment Share on other sites More sharing options...

Administrators Hervé Posted February 12, 2021 Administrators Share Posted February 12, 2021 The BRT6 ACPI patch, whether implemented as a DSDT patch or a dedicated patched SSDT, has worked on all my recent Dell Hackintosh laptops: E6230, E6440, E7250 and 7490. I would therefore expect it to be applicable to your Haswell E5540 too. It's totally unrelated to USB ports (you posts were moderated to that effect in order to avoid all possible confusion) and it's not related to the PS2 kext used either; why? Because, if I use/used DrHurt's R6 kext on my E6230/E6440/E7250, I had to use a different kext on the I2C-based Latitude 7490 and the BRT6 patch was still effective.

Mihari Oyama Posted February 12, 2021 Author Share Posted February 12, 2021 so i need that kexts? - voodooi2c? - voodoops2r6? and i apply the BRT6 patch into efi? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted February 12, 2021 Administrators Share Posted February 12, 2021 According to Dell's own documentation, Haswell E5540 is fitted with regular (not I2C) Alps Touchpad; as such: try Dr Hurt's VoodooPS2Controller R6 to begin with add the SSDT-BRT6 to your config in parallel Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted February 12, 2021 Moderators Share Posted February 12, 2021 No voodooi2c is for I2C trackpad only. Try this one VoodooPS2Controller-Alps.kext.zip Link to comment Share on other sites More sharing options...
