Dell XPS L321X - El Capitan / Sierra Install

[thesuffering]

 

1. Uninstalled VoodooHDA
2. Replace my DSDT with Jake's DSDT
3. Copied AppleHDA_ALC275.kext to S/L/E
4. Fixed perms and rebuilt cache with the following results

Obvious question, you did restart, right?

[thesuffering]

I also keep getting this alert

Updating perms & cache doesn't seem to make it go away.

I installed mine with kext wizard, also repaired, rebuilt with kext wizard too 

[GatorGeek]

Yes...I restarted

Also tried using Kext Wizard

Same results

1st Click Ok on the error.

then Rerun this again until exited with status 77 is gone. Look for the ALC275 in the output

 

sudo touch -f /L*/E*

sudo touch -f /S*/L*/E*

sudo kextcache -Boot -U /

Followed your directions again tonight Jake but had no luck...just kept getting same results I've been getting.

Decided to Google around to see if I could find a fresh copy of the ALC275 kext to download...thinking maybe the copy I have is corrupted.  In my searches, I came across https://github.com/insanelydeepak/Patched-AppleHDA-for-Mac-OS-Sierra-10.12 which led me to download the kext for Audio ID 28 from here https://bitbucket.org/insanelydeepak/hdaenablers-applehda-for-hackintosh/downloads/

 

Upon installing the kext, look what happened

[thesuffering]

Its always such a relief after you spend forever on it and then the damn thing finally works.  Good job!

[Jake Lo]

Looks like you're using an HDAEnabler for layout-id 28 which is the same kext with same layout-id from my files. 

As long as you got it going, great. Now you have audio and HDMI Audio.

[GatorGeek]

You've all been very helpful, patient and kind. Please accept my sincere thanks for your assistance.

Any of you using a BCM94352HMB for wifi?  Ive noticed after sleep it still shows connected but it wont work.  A restart gets it going again.

 

Actually, I think I just solved my own issue.  I forgot to disable "Wake for Wifi Access" in Energy Saver.  I think I had this problem before.

I'm using DW1510 Broadcom BCM94322HM8L in mine.  Have to confess I've not even tested Sleep yet. Perhaps I should do that soon
