Bios Settings

Disable Secure Boot

Fingerprint reader

Disable CFG Lock (via modGRUBShell)

How to disable CFG Lock

This is specific to XPS 15 9500 only (along with its sibling models and previous gen).

Select the modGRUBShell option at startup (OpenCore boot selection page). At the grub prompt, enter the following commands (the first line unlocks CFG, the second line unlocks overclocking).

setup_var CpuSetup 0x3e 0x0
setup_var CpuSetup 0xda 0x0
exit

Restart your laptop and boot into the BIOS. Do a factory reset. Now your CFG lock will be disabled. You can confirm that by running the VerifyMSR2 option.

If you update your BIOS, you may need to do this again but so far Dell has been kind to us.

Brightness hotkeys

The BRT6 patch used by previous Dell XPS models isn't working on the XPS 9500. However, fn+S and fn+B hotkeys are functioning in place of the original fn+F6 and fn+F7.

Undervolting

This EFI comes preinstalled with VoltageShift kext. To undervolt, visit https://github.com/sicreative/VoltageShift (skip the kext loading part).

Notes

Touchscreen and Touchpad currently only working with Voodooi2c version 2.4.4, newer version will break the Touchpad. Touchscreen SSDT-Patch to force interrupt mode included.

For Monterey support I had removed USB-Map.kext, this need to be added in future. Also fakepciid is not working anymore and runned into kernel panics.
