[SUCCESS] Latitude 3470: El Capitan 10.11 / High Sierra 10.13

Recommended Posts

I've been hackintoshing for 10 years on a dozen pc's. But need help on this one.

 

I have installed to and am booting from the internal sata drive and able to get into El Capitan.

 

I'm am booting from the internal sata drive. There are issues with LPC and graphics framebuffer that seem to be dsdt/ssdt or config.plist issues.

 

I'll be glad to post a install method if I can get a little help! Thanks!

 

The specs are:

CPU: i5 6200u

HDD: SATA 256

Graphics: Intel HD 520

Audio: ALC 3246

NIC: RTL 8111Family

 

 

** New Bootpack for 10.13.3**

NOTE: Set DVMT to:   Setup_var 0x434 0x03.   &.   Setup_var 0x435 0x03

ACPI is for BIOS 1.6.2

See my guide here with Skylake HD 520, specifically the Prerequisite section to change your DVMT. Are you sure about the audio being ALC3246 and not ALC3236?

ALC3246 indeed according to Dell's 3470 specs. Should be ven/dev ids 10ec:0256, i.e. ALC256 codec.
 
For El Capitan, try the following Clover on-the-fly AppleHDA patches + attached kexts:

Find: 6102EC10
Replace by: 00000000

Find: 6202EC10
Replace by: 00000000

Find: 8508EC10
Replace by: 00000000

Find: 8319D411
Replace by: 00000000

Find: 8419D411
Replace by: 5602EC10

Patch your DSDT HDEF device to inject audio layout 3.

Yes, I have fixed DVMT to 96MB. I have used your (& others) install guide to get to where I am now. I am booting into El Capitan desktop. Frame buffer and LPC errors during boot. I'm assuming it's dsdt and ssdt related. I have tried rehab man's dsdt/ssdt fix method with limited success.

Thanks Hervé for the ALC256 patches and kexts. I'm including it into the bootpack. See if this works.

Kexts in Other/LE are to be place in /Library/Extensions and then run the permission fix and rebuild cache.

      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 /

Thank you!! Seems to be working a lot better. Had to do a complete reinstall though, the efi partition had some sort of issue (??) I'll report back with more info after more testing. Thanks again!!
