marliwahoo Posted September 3, 2016 Share Posted September 3, 2016 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 3470 10.13.3.zip 1 Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted September 3, 2016 Moderators Share Posted September 3, 2016 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? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted September 3, 2016 Administrators Share Posted September 3, 2016 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 AppleHDA_ALC256.kext.zip CodecCommander.kext.zip Patch your DSDT HDEF device to inject audio layout 3. 1 Link to comment Share on other sites More sharing options...
marliwahoo Posted September 3, 2016 Author Share Posted September 3, 2016 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.

Moderators Jake Lo Posted September 3, 2016 Moderators Share Posted September 3, 2016 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 / Latitude_3470.zip Link to comment Share on other sites More sharing options...
marliwahoo Posted September 4, 2016 Author Share Posted September 4, 2016 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!!

marliwahoo Posted September 4, 2016 Author Share Posted September 4, 2016 You want the L/E kexts in Library/Extensions - not System/Library/Extensions? Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted September 5, 2016 Administrators Share Posted September 5, 2016 yes L/E goes in /Library/Extensions not the one in system folder. Link to comment Share on other sites More sharing options...
