Dell Latitude 7480 - High Sierra: Any how-to?

Recommended Posts

Hi there.

 

Now that I was able to install High Sierra on my old E5430 I would like to do the same with a 7480. Running Windows 10 on this machine makes feel sad.

 

Have you guys seen any procedure to install High Sierra on 7480?

 

Thank you.

 

Mario.

I will try to help you. 

 

Thanks to @Jake Lo I have almost fully working Dell Latitude 7480 with latest High Sierra installed. 

 

If you still need help, let me know I will try help you with the installation and basic configuration. 

I cannot help you with ACPI tables you will need to ask someone else from the forum for help.

Helo, Jake Lo! 

Fanx for you help,  but steel no luck.

with patched DSDT - touch not work, and internal keyboard are switched off. 

With patched DSDT and PS2 kext (btw, why PS2? TP in i2C bus - DLL07A0  , TPD1) keyboard worked, but TP is not. 

P.S.

TP work fine under Win10, Debian, Ubuntu... 

P.P.S.

DSDT in my config already patched for i2c TP, may be in this trouble. 

Here is clear orign actual files.

 

P.P.P.S. 

Then i press to TP - keyboard are illuminate, but mousepointer do not move, key not work, and e.t.c.

HD520 or HD620?

PS2 is for the keyboard. I2C is for the touchpad

Your DSDT was missing the GPIO Controller patch

Why did you remove the VoodooI2C kexts?

Try this, replace Config & DSDT/SSDT

Add all kexts to /EFi/Clover/kexts/Other but AppleBacklightInjector.kext goes into /L/E

Repair permission and rebuild cache

fanx for try to help me! (i2c remove temporality, foк testing).

Try to use you config, but no luck.

Do it : conf and kexts into EFI, (AppleBacklightInjector.kext put into /L/E ), rebuild cache, reboot and got KP.

with you files and conf - got CPU KP.

with you files my conf - got ACPI KP
