Hello guys,

I've recently installed OS X Sierra 10.12.4 on my laptop Dell Inspiron 15 7000 Series, 7548.
 

It comes with
CPU: i7-5500u
Screen Resolution: 3840x2160 4K -- TouchScreen
iGPU: Intel HD 5500
GPU: R7 m270
Clover: v4049

 

what's working:

-no glitch

-hd 5500 is working

-Sound is working with VooDooHda V.2.8.9

-Bluetooth

-Touchscreen

 

​But I can't patch dsdt for Hdmi -Battery status -Brightness with success, so I need help!

 

Thanks

Compress and attach the origin folder here if you want help with patching.

What version of BIOS?

HDMI video or audio?

HDMI video will need FB patching.

HDMI Audio, you might need to have a patch AppleHDA.

What audio codec does it have?

Launch DPCIManager and post a screenshot here of the status

Let's try this

Remove VoodooHDA.kext and AppleHDADisabler.kext

Remove IntelBacklight.kext and/or ACPIBacklight.kext

 

Replace ACPI folder to /EFI/Clover

Replace Config to /EFI/Clover

Copy all kexts in 'copy to LE' /Library/Extensions

 

Repair permissions and rebuild cache

      sudo chmod -Rf 755 /L*/E*

      sudo chown -Rf 0:0 /L*/E*
      sudo touch -f /L*/E*
      sudo kextcache -Boot -U /
 
 
Files should enable audio, HDMI video and audio, brightness control, battery status

That is the conflict I got when running: sudo kextcache -Boot -U /

 

And when I restarted the laptop I got kernel panic...

here is what I did :

- In the new config.plist you gave, I reactivated the mistolen size 10.12.x for broadwell --may be I shouldn't have to do it-- and I boot normally

- brightness doesn't work , sound too -- I think, I did something wrong!

Attach your Clover folder before the change.

Enable minStolenSize patch if you didn't set the DMVT with EFI Shell.

When your run the commands, make sure there's no error. Re-run until it's good.

If you have mod/custom kext(s) in /S/L/E too, then run these commands

      sudo chmod -Rf 755 /L*/E*

      sudo chown -Rf 0:0 /L*/E*
      sudo touch -f /L*/E*
      sudo chmod -Rf 755 /S*/L*/E*
      sudo chown -Rf 0:0 /S*/L*/E*
      sudo touch -f /S*/L*/E*
      sudo kextcache -Boot -U /
