Latitude 5480: High Sierra

Recommended Posts

So, I'm trying to install High Sierra on Latitude 5480 (-9187) with:
Intel HD 630 + nVidia GeForce 930MX
2X8GB SK Hynix 2400Mhz
Stock sata SSD

BIOS 1.9.3, reset to defaults.

I did everything step-by-step by this guide. Literally.
Used 5480_HD620_v1.6.4_HS.zip and  EFI_4458.zip. Also updated ethernet kext and fakePCIID kexts that already existed in kexts/other. Also, booting with nv-disabled doesn't influence at all.
Clover ver is 4522.

I get an "boot-uuid-media" issue, but I recreated installation media several times.



I also got ACPI tables saved via RWEverything.

Go ahead and copy VoodooPS2Controller.kext to /L/E as well

Looks like AppleIntelLpssI2C & AppleIntelLpssI2CController are still loading

which means AppleIntelLpssI2CDisabler.kext is not working.

Manually remove these from /S/L/E

  • AppleHPM
  • AppleIntelLpssI2C
  • AppleIntelLpssI2CController

Repair permission and rebuild cache


Really hard to read a reg text file.

Download this, launch IORegistryExplorer. Save and attach file

OK, I swapped back the files from bootpack and it worked again.
Brightness control works from settings panel.

I updated all the kexts I could find from E/C/K/O, added VoodooPS2Controller (also, installed its daemon), AppleALC, removed ApplePS2Controller, installed latest VoodooI2C & VoodooI2CHID (I have Alps), but nothing changed - audio, keyboard and touchpad not working. Also, I can't get how to fix HDMI (at least without audio).



I mentioned AppleIntelLpssI2CDisabler.kext in S\L\E, and I deleted AppleHPM, AppleIntelLpssI2C, AppleIntelLpssI2CController.
