E7470: some issues with Sierra

[Jake Lo]

You need to restore a vanilla version of that file, it's needed for this wireless device to work. The hot patches are done with the Config.plist file.

After replacing the kext and fix permission/rebuild cache, then reboot. 

See if it shows in System information.

I  restored a vanilla version, rebuild cache, it not show in System information.

 

I check IORegistryExplorer, is this device?

Looks right.

Hi there. I have a Latitude E7470 and I am having a lot of trouble installing OS X. I don't quite understand how to set the DVMT to 96MB. Mine is at 128 MB if I check my display adapter properties. 

I don't understand how to do these steps in Firewolf's guide: 
Step 2.1: Apply the patch to pass the Stolen Memory assertion.
 
 
STEP 3: Injecting AAPL, ig-platform-id
https://www.firewolf.science/2015/04/guide-intel-hd-graphics-5500-on-os-x-yosemite-10-10-3/
 
I can do the middle step:
STEP 2.2: Using EFI Shell to change DVMT settings in BIOS.
 
I can create the bootable USB with no problems, but when I go to install it using clover I end up with a 'panic' as soon as I click 'install' from clover. 
Do you know of any videos that goes step by step? I'm not very good with software

You could skip all the steps you mentioned above, I already have all that documented in the E7x70 guide which is in the bootpack for El Capitan and this for Sierra

You just need to set the DVMT 

STEP 2.2: Using EFI Shell to change DVMT settings in BIOS.

with this command after booting with the EFI Shell

setup_var 0x432 0x3

 

If you still encounter reboot after setting the DVMT, then boot to Clover, hit spacebar and select "Verbose (-v)" and "Don't reboot on panic (debug=0x100)"

Then Boot macOS with selected options.

Post KP here

I did everything you mentioned. 

One problem I am having is after I update my DVMT using the EFI shell (from 0x432 to 0x3), it is not updating when I check the dedicated video memory in my display adapter properties in Windows. It still displays 128 MB. 
Here's the screenshot of the panic when I go to install Sierra using my bootable USB.
 
Second panic is from:
 "Verbose (-v)" and "Don't reboot on panic (debug=0x100)"

What version of BIOS is your system?

 

Try going into Options when you see the Clover loader, use the right arrow to navigate

Select ACPI patching-> Tables Dropping->

Go all the way down and deselect Drop all OEM SSDT

Check all the Drop "SSDT-xx" below that

Select Return

Change DSDT name: BIOS.aml

Select Return, Return

Hit spacebar to select Verbose mode

 

What the above does is to not use the patched DSDT/SSDT if it's a BIOS dependent issue.

If it boots with that setting, then we could try exporting new raw file and I'll repatch them for you.

I replaced another DW1560 from seller, it show this error. Can we solve it?

 

And Bluetooth doesn't work.

you also have to patch for FVCO with clover even with rehabmans kexts.
