YUP that EFI worked! What do you figure got it up this time? Got Sierra installed. Now for post-install questions... a little confused as to all my options here and how to go about doing them. Notes:
  • Your EFI-FINAL didn't boot my system. If I install your new EFI to my boot drive, it boots up fine.
  • How should I configure my final EFI?
  • Anything I need to do with SSDT?
  • Confused as to patching applegraphicsmanagement - what's the deal with that? I installed Nvidia drivers but I get a blank screen when booting; I assume this has to do with that issue.
  • do I just leave the kexts in CLOVER/kexts/10.12, or do I install to S/L/E?
Thanks again!!

The EFI worked for me as well however when I replace the EFI content with the EFI-Final it doesn't boot (stuck on PCI config or something else). It only boots with new EFI like yours r.schroeder but it doesn't recognise the CPU, is extremely slow and laggy and my R9 290 only shows 1280x720 :(

I wonder where do we go from there???


Maybe you should give us your specs and then we can help you :)

So, after a lotof reboots like schroeder got, I'm also further with the "alternate EFI", but I'm stuck at seemingly non-issue... it just stays here:

Hi Nmano, I have a 6800K X99 motherboard, i haven't seen many people getting our combination going (slightly different), but close enough.

In clover configurator is it as easy as erasing the entry for FAKECPUID box in the Kernel and Kext patches section?

I've added a screenshot for you reference if you could help that would be great

I've tried every (i think every i hsould have written it down) combo of OsxAptioFixDrv.efi and test 2.efi

I read on

so that's my board, not sure what's up with it, but doesn't sound good....

Hi, could you help in the installation phase where I remain locked to the black screen:
OsxAptioFixDrv: Starting overrides for System \ Library \ CoreServices- \ boot.efi
Using reloc block: no, hibernate wake: no
I see from your card that we have some similar components (i7 6800k, Radeon RX 480 8Gb) apart from the motherboard that mine is a Asrock X99 Taichi.
You managed to install the Sierra? I am desperate.
Thanks so much.

Here is a full install guide using Unibeast / Clover to install Mac OS Sierra 10.12 on your custom built Haswell E X99 Computer! I made this guide from using instructions gathered from the TonyMac forums. 10.12 appears to be the most solid version of MacOs for x99!

What's working:
Everything!!!! 100% on 10.12!!!!

* Update * 03/14/2017 USB 3.0 section added, there should be no more problems with USB 3.0 support. Also fixed audio I now have native audio working with HDMI audio support! It should all be 100% working properly, hopefully this will be final update for Sierra!

The build:
GIGABYTE GA-X99-UD4 (Motherboard)
Intel Core i7 5820k Haswell E Processor (Cpu)
16GB Corsair Vengence DDR4 2400 RAM (Memory)
EVGA GTX 970 SSC 4GB (Graphics Card)
Sandisk Extreme ii 120GB SSD (El Capitan drive)
Samsung 840 Evo 120GB SSD (Windows Drive for dual boot)
(4) Western Digital Caviar Black 1 TB (Hard Drives)
LG Blu-Ray / CD / DVD Writer (Optical drive)
Corsair Hydro H115i (Cpu Water Cooler)
EVGA SuperNOVA 750 B2 (Power Supply)
Corsair Obsidian Series 750D Airflow (Computer Case)

Seiki SM40UNP 40" (4k Monitor)
LG 24UD58-B 24" (4k Monitor)
Vizio 1080p HDTV 42" (Tv connected from the other room for streaming movies, and gaming)

Requirements for this install:
An empty flash drive for Unibeast + an already working copy of OS X to make the drive.

A usb audio device. I have a Sabrent USB sound adapter, it's plug and play! Link:

Pre installation requirements:
Update Bios to f22 from Gigabyte's Website (for x99 ud4 motherboard) @

Go into bios, use "load optimized defaults"


Thats it.

Bios settings not required, but recommended for this install:
go into bios under frequency settings set "cpu boost 5820k to 4.3 ghz"
set memory settings xmp memory profile to "profile 1" or "profile 2" (depending on your memory speed)

this will overclock your cpu and memory, you may or may not want to do that. i reccommend it. computer definetly runs better with overclocking. It's automatic and the motherboard takes care of all the voltage settings. Use 4.3ghz for your cpu and profile 1 or profile 2 depending on the speed of your memory. I use profile 1 because I am using 2400mhz memory.

Pre Install - Step 1
Use the tonymacx86 method to install "Sierra" to a USB Flash Drive using Unibeast. You will need to make an account on tonymacx86 to be able to download Unibeast.

Here is the link to the guide to make the unibeast flash drive:

Install Unibeast / Sierra To flash Drive using the guide from the link I posted.

Pre Install - Step 2
After installing Unibeast / Sierra flash drive you will need to get "EFI Mount 3 and Clover Configurator".

Get Clover Configurator from

Get EFI Mount 3 from the Downloads section > Community Software @ Link: (must be logged in to view this page)

Pre Install - Step 3
Copy EFI Mounter 3 / Clover Configurator to Your Applications. Then open the EFI partition from the unibeast drive (it should already be mounted).

(If it is not mounted open EFI Mounter 3 and mount the first selection in the menu. Then open the EFI partition from the unibeast drive)

Pre Install - Step 4
Download OsxAptioFix2Drv-free2000.efi from this link: (Source: )

Copy OsxAptioFix2Drv-free2000.efi to your /EFI/ClOVER/drivers64UEFI folder and remove OsXAptioFix2Drv.efi (This is the key to getting the unibeast drive to boot!)

- Thanks to Sunman for the info! <---- reference link

Pre Install - Step 5
Open config.plist from the EFI > Clover folder on your Unibeast drive with Clover Configurator.

In the "Boot" Section of Clover Configurator Tick:


in the custom flags box type
-v -f

Now your ready to install MacOS Sierra!

Install - Step 6
Reboot your computer and choose to boot from usb drive. It should boot into the MacOs installer screen!

Follow the guide from Tonymacx86 to complete the installation:

After 10.12 is installed continue to follow this guide.

Install - Step 7
Now that it's installed, boot once again from your Unibeast drive, but this time select your new MacOs Installation from the clover screen. You should not need any extra boot flags. If it does not boot try adding -f (if you have not added it before). Continue to set up the computer and finish the boot until you see the desktop. Remove your Unibeast drive.

Post Install - Step 8
Download & run Multibeast - Sierra from here:

Select These Options:
Quick Start > UEFI Boot Mode
Drivers > Disk > Intel Generic AHCI Sata
Misc > NullCPUPowerManagement
Misc > VoodooTSCSync > VooDooTSCSync 6 Core
USB > Increase Max Port Limit
Network > Intel > AppleIntelE1000e

Install Multibeast.

Post Install - Step 9
After installing Multibeast the EFI Partition for your MacOs install should automatically mount.

Copy OsxAptioFix2Drv-free2000.efi to your /EFI/ClOVER/drivers64UEFI folder and remove OsXAptioFix2Drv.efi. Also remove VBoxHfs-64.efi (we will be replacing this driver)

Remove VBoxHfs-32.efi from the /EFI/ClOVER/drivers32UEFI folder. This file might also be in /EFI/ClOVER/drivers32 folder (if there is one)

Open config.plist from the EFI > Clover folder on your system drive with Clover Configurator

Post Install - Step 10
In the "Boot" Section of Clover Configurator Tick:


Then go down to "System Parameters" Section of Clover Configurator

In the drop down menu above "Inject Kexts" Select Yes (will be used to enable onboard sound via VoodooHDA.Kext)
Put a check mark in the box next to "NvidiaWeb" (will be used to enable Nvidia graphics card via web drivers)

Then go down to "Install Drivers" under the "Tools" Section of Clover Configurator (Bottom Left).

Make sure these drivers are installed (grey means installed):

Drivers UEFI 64 Bit (Bottom Left Menu): EmuVariableUefi
Extra Drivers (Bottom Right Menu): HFSPlus, HFSPlus UEFI, OsxFatBinaryDrv UEFI

Go to File > Save and save your config.plist. Close Clover Configurator.

Post Install - Step 11
1. Copy My attatched AppleHDA.Kext (in zip file) to /system/library/extensions/ (This is the kext from the original mavericks 10.9.5 installer)
2. Download Multibeast for Mavericks (not Sierra) Here:
3. Install Realtek ALC 1150 audio from that version of multibeast and check "optional EFI installed bootloader support" (so it doesn't install Chimera)
4. Copy both SSDT files from the attached zip file it to /Clover/ACPI/Patched in your efi partition. (SSDT's courtesy of Toleda:
5. Restart
6. Mount EFI Partition using EFI Mounter 3, then use audio_alc_x99-hda-100_patch.command from the attached zip file
7. Restart
8. Audio works now (Really works!)

Now you will have enabled onboard sound with support for HDMI audio as well! (second SSDT adds that, thanks to member
ranadve in this post)

Working audio guide thanks to Toleda!

Post Install - Step 12
Download USBInjectAll.Kext (get the newest one)

Download FakePCIID_XHCIMux.Kext and FakePCIID.kext (get the newest one)

Download X99_Injector USB 3.kext (attached at bottom of this post)

Copy USBInjectAll.Kext, FakePCIID_XHCIMux.Kext, FakePCIID.kext & X99_Injector USB 3.kext to EFI > Clover > Kexts > Other

Delete all other folders inside "Kexts" folder, except the "Other" folder

Now you will have enabled USB with full support for 3.0! (Credit goes to crismac2013 via his post on Page 10, his post described how to properly enable USB 3.0.)

Note: From my understanding USBInjectAll.Kext works with X99_Injector USB 3.kext to enable usb 3.0 support on x99 motherboards. This works in conjunction with the Multibeast "Increase Max Port Limit" patch for full support. FakePCIID_XHCIMux.Kext and FakePCIID.kext are used to determine which devices are USB 3.0 and which are 2.0. If you do not use FakePCIID_XHCIMux.Kext and FakePCIID.kext everything will look like it is a USB 3.0 device under System Report even if it isn't. With these kexts installed only true USB 3.0 devices will be detected as so when plugged into a 3.0 port. The rest will fall under USB 2.0.

Post Install - Step 13
Download and install NVidia Web Drivers from:


Post Install - Step 14
Go to Applications > Utilities > Terminal enter 'sudo trimforce enable' (without the ''s) this will enable Trim if using an SSD Drive (Highly recommended, SSD only)

System will reboot automatically.

Congratulations you now have a fully working x99 Hackintosh running 10.12.x!

Optional Install - Dual Boot with Windows
In order to dual boot with windows 10 you will need to open up your config.plist file again.

Open EFI Mounter 3 and mount the first selection in the menu. Then open the EFI partition and open config.plist from the Clover folder with Clover Configurator.

  • If windows was installed using UEFI Mode:

In the "Boot" Section of Clover Configurator the menu on the top right should say "PBR"

Go down to "Install Drivers" under the "Tools" Section of Clover Configurator (Bottom Left).

Make sure these drivers are installed (grey means installed):

Extra Drivers (Bottom Right Menu): NTFS UEFI

Go to File > Save and save your config.plist. Close Clover Configurator.

  • If it doesn't boot from clover, you have installed windows without UEFI:

In the "Boot" Section of Clover Configurator change the "Legacy" menu on the top right to "LegacyBiosDefault" (it should say PBR by default)

Then go down to "Install Drivers" under the "Tools" Section of Clover Configurator (Bottom Left).

Make sure these drivers are installed (grey means installed):

Extra Drivers (Bottom Right Menu): NTFS

Go to File > Save and save your config.plist. Close Clover Configurator.

You should now be able to dual boot with Windows from the Clover Menu!

Disable Gatekeeper In MacOs Sierra

The Gatekeeper settings can be found in System Preferences > Security & Privacy > General. The Gatekeeper options are located beneath “All apps downloaded from:” with the choice of “Anywhere” missing.

Thankfully, the “Anywhere” setting can be restored to Gatekeeper in Sierra with a Terminal command. First, quit System Preferences if it’s open and then open a new Terminal window. Enter the following command, followed by your admin password when prompted:

sudo spctl --master-disable

Now, relaunch System Preferences and head back to the Gatekeeper settings. You’ll now see that “Anywhere” has been restored. Click the padlock in the lower-left corner to enter your password and make changes, then select “Anywhere” from the list of Gatekeeper options. The security feature will no longer bug you about apps from unidentified developers.

How To Optimize OS X!
Go to system Preferences > Mission Control, untick all check boxes. turn dashboard off (may require log out / log back in)

Go to system preferences > Security & Privacy, Under General > untick all check boxes (may require clicking lock at bottom left of box), fill in bubble on allow apps downloaded from anywhere (now system boots to desktop and auto logs in without needing password) Under Privacy tab > Untick enable location services

Go To system preferences > spotlight, untick all check boxes in search results tab, then go to privacy tab, drag all drives into that tab. This will turn spotlight off, so you can't search, but will make computer faster. If you want to keep search function, don't do this, but if you want faster computer. Turn it all off!

Go to system preferences > notifications, untick everything, then go to notification panel on the top right of screen, and click the grey box at the bottom. Drag any apps with the red coicon next to them to the green icon section. That will turn off all notifications for apps (speeds up computer a bit)

Go To System Preferences > Energy Saver, turn display off after: Never (drag bar all the way to right) untick all check boxes, especially untick put hard drives to sleep

Go to System Preferences > Bluetooth, turn bluetooth off (unless you need it then turn bluetooth on)

Go to System Preferences > App Store, untick automatically check for updates

Go to System Preferences > Siri, untick Enable Siri

Thats about the extent of it,
Good luck!!!!

Corsair 780T
Corsair H115i

I install Mac OSX 10.12 (16A239j) with X99 LGA2011-V3 platform. It’s fully supported now we don’t need add FakeCPUID anymore. 5960X needs only CloverPatch.
I update bios F22J Support Intel Xeon E5-2600 v4, E5-1600 v4 series, Core i7 6000 series CPU
The Samsung SM951 AHCI model is fully supported by Mac OSX Pro.

OSX 10.12 Installation Notes:

Set Mac osx Installer (I updated files)
Remove DSDT and SSDT
Update Clover to latest (_v2.3k_r3652_Special Edition).
Update nvidia latest web drivers.
Set patch 1 Change 15 Port Limit To 30 in XHCI Kext 10.12(99-series)
Set patch 2 5960XPatch 10.12 by Brumbaer
Creative Sound worked with AppleALC.kext
Install X99_Injector USB 3.kext and set your DSDT XHC to XHCI
You have to set IOCPUNumber to VoodooTSCSync.kext.

BIOS Configuration for USB 3 Flash drive with clover

  1. Intel USB 3.0 XHCI Mode Enabled
  2. CSM Disable
  3. XHCI-Hand-off-Enabled
  4. EHCI-Hand-off-Enabled
BIOS Configuration for USB 2 Flash drive with clover

  1. Intel USB 3.0 XHCI Mode Smart Auto
  2. CSM Disable
  3. XHCI-Hand-off-Enabled
  4. EHCI-Hand-off-Enabled
After installation you have to set DSDT and SSDT.

I get Script to generate a SSDT for Power Management


AppleALC Boot Arguments 10.12 you have to add -alcbeta
-v darkwake=0 npci=0x3000 nvda_drv=1 -alcbeta

Enable HiDPI Mode
sudo defaults write /Library/Preferences/ DisplayResolutionEnabled -bool true
Set your DisplayProductName
Set your DisplayProductID
Set your DisplayVendorID
Set Scale Resolutions
Download your file then overrides your display vendorId like this.

Example for my Monitor:
sudo cp ~/Downloads/DisplayProductID-79f.plist /System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-4c2d/DisplayProductID-79f

Now graphics work very well after clover update.We have to set nvda_drv=1 and patched AppleGraphicsControl.kext
