Have any of you had any breakthroughs with getting audio to work again with either your E7440 or E5530 Dell Latitude hackintoshes following the 10.11.4 update? I found the thread below, but frankly I haven't been able to piece together specific steps that resulted in improvement: Link: https://osxlatitude.com/index.php?/topic/8491-dell-latitude-e5530-installation-working-approach/ I installed El Capitan via the following threads, with a LOT of help from the kind people who participate in this forum: E7440: https://osxlatitude.com/index.php?/topic/6461-guide-e7440-with-clover/ E5530: https://osxlatitude.com/index.php?/topic/8491-dell-latitude-e5530-installation-working-approach/ From what I've seen in other places, there are mentions of other HDA files to use, but my installation approaches didn't seem to involve that from what I recall. Any tips for measures I should take a run at? Thinking forward, if I can get something to work successfully, I can post a guide for others to follow that one day find themselves in the same spot I am in at present. Interestingly enough, I noticed that some people on Apple's own support forums mentioned issues with actual Apple-made computers following the 10.11.4 update, where they had been using USB audio devices which now are failing them.

I followed the Dell Latitude El Capitan Clover Guide (fresh install of 10.11.4 with E7440 spec) - right after step 13 of Install OS X El Capitan, I got kernel panic and the syetem reboots. Screen shot attached. I have tried reinstalling three times just in case I missed some important step (and subsequently update my BIOS from A12 to A17). But I got the same kernel panic every time. My system spec: Latitude E7240, BIOS A17 i7-4600u 2.1GHz 8GB DDR3L Intel HD 4400, 1366x768 (non-touch) Intel AC7260+BT I tried using cpus=1 at the first installation, and it went on to complete the installation. But I had no sound (no output device), and the mouse pointer stopped responding to the touchpad, And I got a virtual drive mounted (seemed to be the mirror image) instead of the physical internal SSD. It feels like I am opening up another can of worms. So I abandoned that route. How can I fix this??? Update: Incorporating the fixes in 1 & 2 into bootpak solved the kp issue. Fresh installation was a straight through. Now running 10.11.4 on E7240. Some tweaks: powerd failure https://osxlatitude.com/index.php?/topic/8922-solved-e7240-10114-fresh-install-boot-problem-kernel-panic/?p=59260 Cheers
