OS X 10.11.4 Update

Not open for further replies.
I'm very new to being a member of this site, got into a bad auto accident and my build is 10.7.5 Lion, is it safe to update to El Capitan with a build of Gigabyte z68xp-d4 3.59 Intel Core I7 Ati Radeon HD 6800 Series 2048 MB? I ran into a slew of issues after updating to 10.7.5 Kernel re kext issues with my graphics card.
Today Apple released 10.11.4, the fourth major update to OS X El Capitan. Update any supported system using the built-in Software Update functionality through the Mac App Store, or by using the standalone installer available from

Be sure to back up any important data, and if possible clone your hard drive before applying the update. If you have any issues post-update, boot using UniBeast created USB, press spacebar, and boot using Safe Mode.

What we know about 10.11.4 so far...
  • OS X Build 15E65
  • Kernel updated to Darwin 15.4.0
  • Kernel support for Skylake Systems without 'APIC Fix'
  • Updated Intel, NVIDIA, and AMD graphics drivers
  • This update will replace your audio drivers. If you enabled Realtek onboard audio using MultiBeast or the CloverALC110 script, no changes will be necessary.
  • Install OS X El Capitan App Updated - If you downloaded El Capitan from the App Store prior to today, and you want to have the latest version on your backup installer USB, simply log into the Mac App Store and click Download. The updated 10.11.4 Install OS X El Capitan App can be found in the Applications folder. You may then re-create your UniBeast installation USB.

Testing is now underway- this post will be updated. Good luck, and let us know how it goes! Report your results here.

I'm currently on a Skylake i7-6700k system with a GTX 650 that had graphic acceleration working by default in 10.11.3. Since updating to .4, I can now only boot with nv_disable=1 which in turn gives me horrible resolution and graphics performance. Any thoughts on how to get full acceleration back?

Hi guys,
I am currently finishing my update from a rock-solid stable Mountain Lion hackintosh to a new Windows 10 / El Capitan dual boot.
I am writing my little guide as a contribution when I am done.
This is my problem: when I first install El Capitan from the USB EVERYTHING is perfectly recognized. Ethernet and USB3. Nothing needed from Multibeast. I can install FakeSMC and no problem. But the moment I update to 10.11.4, USB3 stops working and Ethernet card gets unrecognized.
I'm so sorry, my mistake. My problem has nothing to do with OS X Update but with FakeSMC. The moment I install it, goodbye.

If I install 7/8/9 USB drivers from Multibeast I am able to use all my ports (both USB3 and USB2) as USB2.
Is there an easy way of using first installation's kexts in 10.11.4?
What else can I do?

Thank you so much in advance,

Upon updating to 10.11.4, my audio stopped working. I downloaded the MultiBeast package for Yosemite and ran the following file, which immediately resolved my broken audio after rebooting. Hope this helps someone else.

Same deal with 10.11.5 - just reapplied the attached file.
I have updated my hac to 10.11.4 last night via AppStore. When I booted it for the first time everything seems to be broken. My hac does neither boot in normal mode, save mode, with nv driver disabled nor from recovery disk or the installation USB.

Verbose mode gave me the error in the attachement.

Does someone know how to fix this? Restoring from TimeMachine Backup would help as well.

Thanks to everyone who can help me!

Nice and easy. I'm running Clover and updated via the App Store.

I made backups of my boot drive and EFI drive, then clicked updated in the App Store. When it rebooted, I checked to make sure TRIM and audio were working, then rebooted again for good measure. So far so good. :)

Clover, Yosemite
Realtek ALC898 with High Quality 110dB SNR HD audio
after further investigation it appears my /var/log/system.log is littered with:

Mar 23 12:38:58 nineofnine kernel[0]: MT=>Free:bEndMLMEEvent = 0, bEndControlEvent = 0, bEndBulkOutDataEvent = 0, bEndDequeuePacketEvent = 0, bEndLoadFWEvent = 1, bOnAsicSwitchChannel = 0, bOnMlmeHandler = 0
Mar 23 12:39:28 --- last message repeated 5198 times ---

does anyone know how to fix this? I have no idea where it comes from (well i guess the kernel)

EDIT: Figured it out, its my wifi dongle driver: RT2870USBWirelessDriver.kext that is responsible. Guess its time I get a proper wifi card..

Did you solve this issue with this USB WiFI or did you buy a different one?

This issue also happened to me (also a lot of those lines during boot) when I got a new update for Mojave OS
