X99 and El Capitan Install and Misc

[Sunman]

@Sunman: The easy solution is VoodooHDA ...

VoodooHDA does not helped even the device does not appear...

There are plenty of threads related to El Capitan, yet most of them are irrelevant to the X99 unsupported chipset. Let's attempt here to gather the info we need for all X99 boards...

Installer: We'll create a USB El Cap installer using Apples "createinstallmedia".
1. Verify you have downloaded and have "Install OX X El Capitan GM Candidate.app" in your Application folder. (Of course this will change as updates continue)

Format a 16GB+ USB with GUID partition mapping and name it Install. (8GB drives may work for you but I've had a problem with them)

In terminal run the following script.

sudo /Applications/Install\ OS\ X\ El\ Capitan\ GM\ Candidate.app/Contents/Resources/createinstallmedia --volume /Volumes/Install --applicationpath /Applications/Install\ OS\ X\ El\ Capitan\ GM\ Candidate.app --nointeraction

Be patient, this will take some time...

I'm assuming your motherboard supports UEFI therefore we're installing CloverUEFI (most info here is likely to work with Clover legacy but I have no ability to test it).

Now we need to install Clover r3270 or later to (Get it HERE) to the "Install OS X El Capitan GM Candidate" USB.
Run the Clover installer with these settings.

When the installer completes the EFI partition will be mounted, don't close it.

Now we need a few more files... You can get them here:
https://www.dropbox.com/s/5ze6a53p2uu91ud/HFSPlus.efi?dl=0
https://www.dropbox.com/s/jl2rqup7xvag95b/VoodooTSCSync?dl=0
https://www.dropbox.com/s/mv424vade0ltom9/FakeSMC?dl=0

Copy FakeSMC and VoodooTSCSynce to EFI/EFI/Clover/Kexts/10.11
Copy HFSPlus to EFI/EFI/Clover/drivers64UEFI
Copy the attached config.plist to EFI/EFI/Clover/
Delete EFI/EFI/Clover/drivers64UEFI/VBoxHfs-64.efi

Reboot to your installer, select Install OX X El Capitan GM Candidate and follow the prompts. Again, Reboot to your installer, select Install OX X El Capitan GM Candidate to complete the installation. Install Clover to your HD following the same instructions as installing to your USB, your HD should now be El Capitan bootable.

There are so many variables right now it's impossible to cover them all, that's what this thread is about!
This process should work for most X99 gigabyte boards and hopefully with some input we can address all X99 issues...

Note: nv_disable=1 is only needed with unsupported nVidia GPU.

This one worked for me with these boot flags : -v npci=0x2000 nvda_drv=1 + inject Nvidia in clover. Audio is working out of the box.

My rig is Gigabyte x99 UD4 6 cores i7 and Geforce GTX 580.

Thanx !

can anyone help me? I am stuck in this screen after I press enter in clover. I have tried npci=0x2000, nv_disable=1, kext-dev-mode=1, cpus=1 and also the two different osxaptiofixdrv files from clover.

My system is:
i7 5960x
Asus Rampage v
64gb ram
2x Nvidia 980 GTX

The same usb stick reach the installation on my other computers, so maybe something has to do with the 8 core cpu or the motherboard.

What Clover version, try 3270 or later.

I am using 3270 clover. I also tried chameleon but after I hit enter it loads a few lines and then I get a black screen. Tried also to disable nvidia with the appropriate kernel flag but still the same. any ideas?

Had some time Sunday afternoon to try with the Asrock X99M Killer.
Clover boots great - UniBeast UEFI installer, which worked fine on a Z77 and a Z87 build gives me a runtime error, same as I used to get from the Clover boot. Will try using a drive with Clover booting from HDD out of one of the other builds and see what happens.

Guys, no solutions actually with 10.11 on 5960x.

Soon hope..

Hi what you mean audio worked out of the box? The 1150 on board audio? Can you share your EFI config?

That will be an interesting test. There just has be something flaky in that ASRock bios... I'm hoping you get it running, there's some weird stuff going on with X99 and ElCap and I'm hoping you can test, lol...

There is. It can be corrected using a linux boot disk and poking the correct entries into the UEFI using efibootmgr.
