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.  

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: 6102

I'm SO happy. I finally solved my video problems. iTunes trailers and some video in safari were not working. I tried IntelgraphicsFixup.kext by Ivs1974 and it's now fixed!! YES!   New 10.13.3 bootpa

As always a BIG thank you for your help!


It's BIOS 1.5.2. I tried several methods of bios downgrade (including bios recovery mode) it would not accept any bios later than 1.5.2. Searching the web for answers I found:

1. enable Bios downgrade (I did that)

2. Turn off TPM (done)

3. BIOS recovery (won't accept any .RCV file with bios earlier than 1.5.2)

Yes! All fixed. Thank you!!


No other changes needed to be made. All networking is working.


One note: I used hdaenabler.kext because I couldn't compile your last dsdt after I tried to change layout id. Otherwise ...... Perfect!


Here are the notes from the 1.5.2 BIOS update:

After the fixes from the last bios update , I was still having problems with playing video - both from the internet and from my HD after sleep. I noticed there was a newer bios (1.6.2) and tried it. But now networking is broken again. Is there a simple guide specifically for patching dsdt/ssdt on latitudes? I find most of the guides complicated. I hate to ask, but could you patch these?
