    Amazing tut, thank for all.

    My computer:

    MB: GA-X79-UP4
    Graphic card: EVGA 780 Ti
    i7-4930K

    I have one problem, when i try bot with this flags:

    -v cpus=1 npci=0x2000

    Try multiple different flags with the same result

    Can’t initiate, system send me this error:

    **** [IOBluetoothHCIController][SearchForTransportEventTimeOutHandler] — Missing Bluetooth Controller Transport!

    Bios good configure. Make that progress with clover:

    Navigate to /EFI/CLOVER/ and replace default config.plist with attached config.plist*
    Navigate to /EFI/CLOVER/kexts/10.9/ and add FakeSMC.kext
    Navigate to /EFI/CLOVER/kexts/10.9/ and add NullCPUPowerManagement.kext
    Navigate to /EFI/CLOVER/drivers64UEFI/ remove VBoxHfs-64.efi and add HFSPlus.efi

    A greetings!.

      Hung on the GPU. Native drivers do not support the TI only the retail so use clover to block the Nvidia drivers.

      • CheChu10G says:

        How can block nvidia drivers? In options of bootlader?

        A greetings, and thank you very much for your reply

      • CheChu10G says:

        I test with flag: nv_disabled=1
        With the GraphicsInjector=YES.

        But i cant start. the same problem.

        Ah, I forgot to mention:
        When i try with that flags and start in safe mode, i see “Uptime” bla bla bla, and one second later, restart my computer.

        And with Chimera, i could see the installation with my same hardware, How is that possible?

        Thank you for all 😉

      • rampagedev says:

        Because they tell the system to look for another CPU that does not exist this breaking the system into working. It is a horrid thing to do…

      • CheChu10G says:

        I cant make nothign, then?
        When i start in safe mode i see that screen one second, and later restart my computer:

      • rampagedev says:

        This is not a pick and choose when using boot flags. Stop using Boot flags you do not understand!

      • CheChu10G says:

        Yep, that screen was realize when i test multiple flags in the same time, but with “-x -v npci=0x2000 cpus=1” was the same…

        I create again my USB with your tutorial and make really good.

        Thank you very much for all 🙂

    • Hi Rampage,

      First of all thank you for the excellent guide. I followed it step by step but when I get to the point where I start the installer, it starts to run and then hangs with this screen:

      I have tried just about every combination I can think of. NVidia injection is off by default so I tried checking the box and the same result. I’ve tried GraphicsEnabler=No and nv_disable=1, but I figured that, that wouldn’t matter since it isn’t in your Clover guide and is used only for MyHack.

      If it helps, I have an ASUS GA-Z77X-UD5H and a GTX670 with an i7-3770k.

      Any ideas? I’m completely lost at this point.

    • Ok, so I have Yosemite installed as per step 9 of Part 7. Step 10 says to move on to Part 4. Am I correct to assume you mean Part 8?

      At this point, I am able to boot into Yosemite but only if I boot from the USB drive I made using your instructions. I will admit I’m completely new to Clover. I had been using Chameleon up until now.

      I did try running the Clover installer on my system drive using the settings you provide for the USB drive, but it doesn’t work. I have a second drive that runs Windows 7, and without the booting from USB, it just boots Windows 7.

      Thanks for all your help!

  2. Extingquish says:

    Hello, First of all, I’m a complete noob to hackintoshing, and I have a couple of questions, hopefully not to dumb :S
    Do you have any plans to post the AMD guide any time soon? I’ve tried googleing around for other guides, but with no success.

    Also, I know it’ll be more involved, but is the process for AMD CPUs similar to the Intel one?
    If it helps at all with the guide, here are my specs:
    Mobo: Gigabyte 970A-DS3P
    CPU: AMD FX6300
    GPU: AMD R9 270

  3. Hi,

    My system is:
    ASROCK X79 EXTREME9
    Corsair 32GB DDR3 1600Mhz Dominator
    EVGA GeForce GTX 560 Ti FPB
    Intel® Core™ i7-3930K Processor

    I am trying to install mavericks 10.9.4 with clover but I am stuck on Missing Bluetooth Controller Transport. I read in a earlier answer from you it is the GPU can this be the case? I have a ASUS 650 TI 2 GB also should I try this instead?

    Thanks

    • rampagedev says:

      Enable Nvidia injection in the Clover menu.

      • Hi,

        That didn’t work still the same issue:
        **** [IOBluetoothHCIController][SearchForTransportEventTimeOutHandler] — Missing Bluetooth Controller Transport
        But I also noticed that I have this:
        BootCacheControl: Unable to open /var/db/BootCache.playlist: 2 No such file or directory…!

        I have done the Installer USB followed your guide and Kexts etc. accordantly:

        Navigate to /EFI/CLOVER/ and replace default config.plist with attached config.plist found in “X79 DSDT” FOLDER
        Navigate to /EFI/CLOVER/kexts/10.9/ and add FakeSMC.kext
        Navigate to /EFI/CLOVER/kexts/10.9/ and add NullCPUPowerManagement.kext
        Navigate to /EFI/CLOVER/drivers64UEFI/ remove VBoxHfs-64.efi and add HFSPlus.efi

        A other issue I have is when I Remove Clover installer USB from my PC and put the Clover installer USB in my Mac I can’t see the EFI folder anymore. How come?!

        Thanks

      • Hi,

        I have installed the ASUS GTX650 card and I have the same issue:
        **** [IOBluetoothHCIController][SearchForTransportEventTimeOutHandler] — Missing Bluetooth Controller Transport
        And
        BootCacheControl: Unable to open /var/db/BootCache.playlist: 2 No such file or directory…!

        The good thing due is that the BOIS don’t reset my CSM to enabled.

        Do you have any other suggestions?

        Thanks

      • rampagedev says:

        Hung on the GPU. Disable injection for this model.

    • CheChu10G says:

      U try with “-v -x” ?

  4. Marco says:

    Hi Rampagedev,

    these are my specs:
    – AsRock Z77 Extreme4 (Patched BIOS 2.70)
    – i5 3570k
    – AMD HD 7950
    – SSD 840 Pro 256 Gb
    – 8 Gb RAM Corsair Vengeance

    i have a problem: since i need to run also win7 on my machine, i need to keep CMS enabled.
    Iv’e managed to install 10.9.3 with clover disabling CMS, and the only “problem” was that i had 2 monitor showed by system info (1 HD4000 and 1 AMD HD 7950) even if i have both cable connected to a single one.
    Enabling CSM causes me to only been able to reach the desktop screen with -x argument. Without -x i’m getting stuck at verbose screen with bluetooth error. Even when i can reach the screen with -x argument i see like 3 desktop overlapped on the sides, showed up on the upper part of my monitor.

    I think this is related to Graphic kext, what do you suggest me to do?
    Shall i edit the Framebuffer personality (Even if you wrote that is not needed anymore with newer OS)?

    Thanks in advance

    • rampagedev says:

      Sounds like a dual link issue with your onboard graphics.

      • Marco says:

        Ok, i’ve managed to solve dual link, and also i can boot with CSM enabled. I’ve injected ATI and FB (Hamachi) in clover boot option, and in safe mode boots fine and shows the right video card, but i have some graphic glitches when i move windows, open menu, seems that it’s not working as it should. If i try to booot in verbose only, i’m getting stuck on [IOBluetoothHCIController][SearchForTransportEventTimeOutHandler] — Missing Bluetooth Controller Transport!

        Do you suggest to edit personalities or it isn’t needed anymore? What do you suggest?

        Thanks in advance.

    i try the fresh install 10.9.5 (vanilla install)

    create USB bootable flash drive with myhack copy this kernel and replace the system.kexts to the usb bootable flash drive

  6. Andrei says:

    Hi Rampagedev, thanks for all the useful info. I’m building my new hackintosh (made sure everything is compatible), just waiting on a few parts left.

    Here’s my situation tho:
    I own a macbook pro and I wanted to use its SSD (backing it up first) (OSX 10.8.5) for the new build, would I have to wipe it out and follow all the steps or is this an advantage and it would save me some?

    This is my main doubt before I start working on it

    Thank you

  7. Dan says:

    Hello,
    Does Clover not support PS2 Keyboard? Everything works great except that.
    Thanks for all the great work and support….!

  8. Thomas says:

    when i install kexts and repair permissions the kexts will not load. -s and kextcache -prelinked-kernel will not work…?

    • rampagedev says:

      What method are you using?

      • Thomas says:

        what do you mean exactly? i use clover bootloader without kext-dev-mode=1…kext install and repair permissions with kext wizard. then i boot the machine incl. -s in boot args and /sbin/fsck -fy
        /sbin/mount -uw /
        kextcache -prelinked-kernel
        exit
        will not load the kexts! after that i boot with -f, same issue. the kexts will not load.

      • rampagedev says:

        Your on your own since you failed to follow the guide provided and mixed other methods. If you follow the the guide you can avoid the issues you have created.

  9. Mathew says:

    Worked for me after some trial and error. Thank you so much for your work. I am currently running 10.9.5 without error and it is brilliant. Will be updating to 10.10 in the near future.

  10. Andy says:

    Hi. I made the Clover boot stick but the install button does nothing. How do I replace the EFI? you’ll have to excuse me for being a noob thickie.

  11. CuJu says:

    Thanks for your work Andrew!

    Installed 10.10 with Chameleon on Asus X79 Sabertooth, i7 3930k CPU, Nvidia (EVGA) 680 GTX, 32GB DDR3 1600MHz RAM, all used to work well with your Mavericks DSDT. Now with Yosemite and Chameleon 2.2svn r2399, Chameleon fails to boot and reports, “Memory allocation error! Addr: 0x85cd128, Size: 0xa931, File: free, Line: 0. This is a non recoverable error! System HALTED!!!” Followed the install guide above. Any obvious oversights I may have made?

  12. Do you know that with myHack method when you’re about to “Choose your install type…” All they have for OS selection is 10.9, 10.8, 10.7, 10.6. There is no 10.10 in there just a heads up.

  13. Vinicius says:

    I am not able to do the work USB3.0. None of the front or rear USB3.0 are working. Only USB2.0. The audio, video, etc are working. You know how I do to work all USB3.0 ??
    Rampage IV Extreme – i7 3930k – Radeon 7970.

  14. Seven0S says:

    Sabertooth x79 – i7_3930k – GTX 780
    Audio do not work. USB 3.0 do not work even with the driver on x79 DMG. Where do you set the SMbios? To recognise that is Mac Pro 6,1.

    • rampagedev says:

      There are issues with that SMBIOS since 10.9.5 as I stated here on this site.

      Use the audio patch provided on the DMG for 10.10 as it does work.

      USB 3.0 kext works on all systems tested during testing with the DP and GM with your board and many other. Post a IOreg if you want more in-depth answers about your issue.

  15. Dan says:

    Question?
    When using NVIDIA Driver manager I am not able to switch from OS X Graphics Driver to NVIDIA Web driver. I am able to switch it in the pane and it says to reboot but when i do it reverts back to OS X Default.
    Any ideas?

  16. Generic Extensions To Boot? or my Mobo Kext + 10.10 driver?

    What about ssdt and ssdt-1, work in 10.10?

  17. Dan says:

    Is there a way to edit the config.plist from outside the os using clover? Like using terminal from install usb.

  18. There must be another way to do this. Is it really a must to disable CSM? I have tried Clover, Chameleon USB Installer and I cannot get audio/cpu management to work correctly. My sounds pops at first play of anything then it does not do it again. My benchmark(geekbench) are no where close to 10.9.5 levels. I even tried tony’s install crap since I’m so desperate and I still get no joy. i7-4930k, gtx 780. I also must continue to use npci=0x2000 because my screen goes to black every single frelling time and I can see activity on my HDD lights… so the machine must continue to load to the login screen. I almost think 10.10 is no where ready for hackintosh purposes. I may fall back to 10.9.5 after tonight since its 2days since I tried 10.10 install.

    Thanks for your guide though. :/

  19. muzzman1 says:

    So I did a fresh install of 10.10 using a real mac. Then ran clover on the new ssd.Moved SSD to Gigiabyte GA-X79-UD3, 4930k, Nvidia 520. Was fine on 10.9. Put Kexts and ssdt in appropriate folders as per the guide. Booted with :
    -v cpus=1 npci=0x2000
    kext-dev-mode=1
    Hangs on GeForceSensors (pci2) started.

    Any advice would be greatly appreciated.

  20. Muzzman says:

    What is the syntax for that flag? (Sorry I’m a rookie!)

  21. Artwo says:

    Hi rampagedev !

    Thanks for this tuto 🙂
    I’m trying to install Yosemite with your Clover method for many hours now… 😥

    When I try to boot with the commons boot flags, my install stop at “DSMOS has arrived”
    Picture : http://bit.ly/ZDAggl

    I’ve to enter this : ” -v cpus=1 npci=0x2000 kext-dev-mode=1 ” in Options > Boot Args ; right ?

    My PC :
    _ Intel Core i7 4930K
    _ Zotac GeForce GTX 780 Ti AMP Edition – 3 Go
    _ Asus P9X79
    _ Corsair Hydro Series – H100i
    _ G.Skill Kit Extreme3 4 x 4 Go PC12800 ARES CAS9
    _ Corsair AX860i Modulaire – 860W
    _ Crucial M550 – 512 Go
    _ TP-Link Carte Wifi PCI-E TL-WDN4800
    _ Western Digital WD Red 2,5″ – S-ATA III – 1 To

  22. So I’m using the latest X79 DMG. Sound is offline still after running “audio_realtekALC-100.command”. I rebooted right after running the command on terminal because it looks like it installs it but since nothing happened, the command also leaves a folder on the desktop so I installed the appleHDA kext using KextHelper but still no sound in Output section in System Preferences after reboot. Geek bench values are still lower by 5k points than 10.9.5.

    This are the kexts I installed from tonight’s x79 DMG:
    FakeSMC.kext
    GenericUSBXHCI Beta
    AppleIntelCPUPowerManagement
    Chameleon — Extra folder copy to Macintosh HD
    Move the necessary Nvidia SSDT.aml, SSDT-1 and SSDT-2
    Rebooted
    Ran audio_ALC892-10.10 command to generate the AppleHDA kext
    Rebooted. No sound still and processor is not scaling properly based on intel power gadget.
    I will continue on and try other full install ideas and even fix/repair permissions and will report back.

    thanks.

    Hi rampagedev, thanks fot great work, I have some troubles with your guide.

    1. I created USB installation drive successfully with your clover script, it boots up, but when I mounted the EFI of USB in Mavericks it was completely blank. No folders, nothing. I copied the folders structure from my Mavericks EFI (on my Mavericks drive Installation Clover works without any problems). Is it a problem of mine or did you miss something in your guide?

    2. I can’t install Yosemite, after 5-10 Minutes of loading my Monitor turns off and nothing more happens. I have a native EVGA GeForce GTX 770 and I am wondering what must I do now? Do I need GraphicsEnabler=No or something else? Can you please add a part in your guide which graphic cards needs some more flags and which not? And what must I do now?

    3. I used config.plist for clover from my motherboard dmg from your site (x79-up4), but I have added some more SMBIOS strings for MacPro6,1 identification there. Can it affect my Graphic Problem?

    Thank you for your word and your answers!

    • rampagedev says:

      You failed to follow my install guide and edited my files creating your own issue. Do not modify my files as you will create issues such as this one. If tou had not edited the files you would have been able yo boot. Start over and this time only use the files provided and nothing more. Ok.

  24. VLD says:

    Hi Rampagedev !

    Thank you for awesome tutorial – did clean install of 10.10, everything works as it should work ! But then i ran in to trouble. Before installing, not to mess things up, i disconnected all other hdd and ssd drives. Config before installation of 10.10 :

    10.9 chameleon
    GA-X79-UD5
    I7-4930 OC 4.25
    32 GB Kingstone ram
    ATI HD5770

    1×120 GB Kingstone SSD ( 10.9 and apps )
    1x1GB WD Caviar ( data, user profiles for 10.9 )
    4×1 GB WD Caviar drives as apple raid ( video disk )
    1×120 GB Kingstone SSD ( windose 7 )
    1×1 GB WD Caviar ( windose user files and projects )

    Config after installing 10.10 :

    hardware the same
    1×120 GB Kingstone SSD – installed 10.10 and clover on EFI partition

    And here is the problem – after i connect all hard disk drives of apple raid volume clover, doe ‘s not boot, shoves blank, black screen with no menus e.t.c. If i disconnect one drive – everything is ok, boots like a charm. Any ideas, suggestions ?

    Thank you in advance !

    VLD

  25. VLD says:

    Finally got everything running ! Step by step :

    connected all HDD drives and SSD drive where 10.10 is installed
    plugged in USB install flash with Clover installed on EFI partition
    power on … F12 … boot from flash
    then from Clover boot menu chose to boot 10.10 from SSD where it’s installed
    system booted without any problems

    mounted EFI, checked that all files are in their place. then i removed flash and rebooted system. guess what – everything is fine now ! system powered on booted directly to Clover menu and then to 10.10. I really don’t know what was wrong before, no idea …

  26. Comrad8g6 says:

    Hey rampage I’m having problem booting into installer using clover, created the usb changed the csm use the boot flags u said but in verbose good it does not hang at anything it runs through and in the end the screen goes black as if the welcome screen is about to come up but then signal is lost nothing comes up.

    asus rampage iv
    3930k
    nvidia gtx 780

    • rampagedev says:

      Make sure you are using the correct flags with Clover…

      • Comrad8g6 says:

        well I used your config file the npci=0x2000, the kext dev flag, v and cpus=1
        by the way is and R9 290x supported under 10.10 I’m thinking of changing the GPU because i think it will be better for Final Cut Pro X

  27. Pandorra says:

    I have Radeon HD 5850 on R4E
    1. Is this Card is ok for UEFI boot?
    2. Can I make the clover usb installer on a 10.9 installation on my PC? it uses chameleon bootloader

  28. osxfr33k says:

    Hello rampagedev, I am looking to upgrade soon. I will be installing Yosemite with Clover bootloader. I am debating which MB to get, Asus ASUS RAMPAGE IV GENE X79 or ASUS SABERTOOTH X79 unless there is one even more compatible? I am also looking at the Xeon E5 2680 v2. Are all 10 cores working? Power Management for CPU? Any of the MB components work out of the box like USB 3? Do you have a specific guide for this motherboard and CPU combination?

    Thanks

  29. cberthe says:

    I have a Rampage IV Formula with a i7-3930k, i followed the tutorial and had no problem to create de key, the problem is i can see the key in boot menu, select it but clover doesn’t start, it’s start my default Windows 8 installation ! Do not understand why i cannot boot the key … I have an old BIOS version 1305 … something goes wrong but i do not what because i had no error at all during all the steps of the tutorial …

  30. enesemini says:

    Hello Andrew,

    As I’ve never done an update to my hackintosh I don’t know what to do right now. Your 10.10 Install Guide seems to be an Install guide from scratch and it doesn’t say what to do if you want to update. There is an update guide over at tonymacx86, but I did my hackintosh with myhack and chameleon.

    Is there a guide for upgrading or did I miss something?

  31. osxfr33k says:

    @rampagedev,
    Thanks for sharing all this wonderful work of yours. In the clover config I see the tables you drop ssdt dmar, however I don’t see drop OEM ssdt. When you open clover configurator that option is not ticked. Since you have which tables to drop is that option ignored? On one of my haswell devices I drop the tables as you do but also enable drop OEM ssdt. Thanks

  32. mikko says:

    I found your site today. I was previously eyeing on another hackintosh forum, which starts with a “t”-but although it’s informative and active and all that . . there’s something vague about it. I can’t put my finger on it, but I like this one better 😀 Seems more open and intuitive! ((I will donate as my build is up and running :DD))

    Here’s my thing: Due to certain softwares I use, and which are compatible only through to 10.8. I will need to stick with 10.8. The install guide on this page says “10.6 to 10.9 using myHack”, so am I ok if I use myHack to install 10.8 on my system: Asus Z97 Deluxe / Intel 4790k with Intel 4600 graphics? I’m new to building PC’s so I have to make sure everything.

    And a second question: Is it possible to make the system dual booting? I’d use win8 on another ssd.

    Thanks so much, you’re doing AMAZING work!!!!!

    • rampagedev says:

      You have to use 10.8.5 and use clover. You would have to make the installer usb like you would on a real mac. My z97 msi build runs on 10..8.5 and everything works with a bit of effort…

      • mikko says:

        Very cool! Is it possible to extract the needed installer from DVD?

      • rampagedev says:

        There have never been a DVD of 10.8.5. Get the App from the App Store.

      • mikko says:

        Good evening. The Clover guide says: “14. Clover Bootloader is now Installed 26: Download the following command file for 10.9 here and for 10.10 here”. Where are steps 15-25? And where can I locate the command file for 10.8?

  33. mikko says:

    Ok, will do! TY!

  34. mohamed salem says:

    Was loaded Hakntosh Mafrcks 10.9 device dell t 5400 and has already worked without problems, but i updated and that time did not I log back on Almfrcks how I can I remove this update in order to re-machine as it was informed that what I’m seeing is but the screen keeps freezing with the gray apple on it

  35. eyevuemedia says:

    I have successfully installed Mountain Lion with your MyHack install guide over a year ago. I am looking to create a new install with Yosemite on a separate hard drive to test it out. I am using your Clover guide to create an install USB stick. For some reason nothing happens when I use the 10.10 command line script. I enter a password on the terminal screen and it just disappears. The Clover drive is formatted properly and the EFI drive is mounted on the desktop. I am using a real Mac Pro at work to create the USB installer.

  37. Can you recommend a decent USB 3.0 Pci Express adapter? Thank you.

  38. Lysander Lenihan says:

    Heya, Tried updating my 5 series to yosemite running a gtx 650 from 10.9.5, but at desktop screen goes dead. Don’t know if its something to do with the pcie other cards in there, a wifi and sata3. Did the same method, updating 10.9 w/app on my r9 290 system and it worked fine. Don’t know if its because of the uefi bios. Also the real mac pro with a 660 ti. Was thinking about trying on the gtx 275 system uefi but not sure if it will be a success. Run clover on all.

  39. thejay69 says:

    Hi Rampage, thanks for your web and job.

    So, in this guide I don´t understand step Part 6. What is its utility?
    If no part in the realization of USB installation

    PD: sorry for my english

    Hi,

    installed Yosemite with unibeast usb stick to a x99 MB. It boots fine from the usb stick into the installed OS X, than i installed clover to the HD (drivers etc). After reboot clover boot loader only finds the recovery partition as the only bootable drive. What am I missing?

    thanks for your help

    HI,
    I used myHack to install 10.9, worked great – Thanks! I then used UniBeast MultiBeast to upgrade to 10.10, It’s fine, except audio fails after returning from sleep. ( and iMessage broke as expected )
    No other issues on GA Z77 DS3H board.
    Query – Is the myHack.kext file still needed, should I remove it or ignore it? myHack.kext is in /S/L/Ext/

  42. I have a question. So on part 5, where am I installing the boot loader to. You have it selected to “Macintosh HD”, but obviously I don’t have any operating system on the computer I’m looking to install on. So where am I installing clover? on the flash drive?

    I followed the Clover instructions for 10.10 but my USB stick wouldn’t boot (gave a gpt error; yes it was tested on multiple USB2 ports) so i used a real mac to install 10.10 onto a SSD and copied the kexts per muzzman1’s experience. Also copied the revised config.plist too but the SSD would not boot (tho it was the sole drive). So i connected my old working SSD with 10.8.5 on a
    GA-X79-UP4 and booted the 10.10 SSD with cpus=1 npci=0x2000 kext-dev-mode=1 nv_disable=1. The boot hangs at “New Power Throttle state:1 Old state:0”. Any suggestion on what to do?

      Hung on the GPU. Use the disabler Nvidia Flag. Then install the Retail Drivers.

        Thanks for the suggestion, but as you can see from the post above, i tried nv_disable=1 to no avail. Eventually, if i waited about 5 min, i would get ‘Resetting IOCatalog’. Since then, i removed the new Broadcom card (which draws power from a USB header too) and went back to the old 802.11n card and now don’t get the New Power Throttle error. Here is a link to the most recent screen http://www.biodan.org/misc/hex/yosemiteBoot3.jpg with -v -x cpus=1 npci=0x2000 kext-dev-mode=1 nv_disable=1 (with or without PCIRootUID=1 or 0). FYI, there is a single low-end Asus EN210 video card, i7-3930k and 2 SSD’s (10.8.5 and the 10.10– even tho i used Clover 3021, the 10.10 SSD wont boot on its own, previously i added the boot from the i386 (chameleon) to the 10.10 USB stick & it would boot but would allow me to install- thats when i went to putting 10.10 onto the SSD from a real mac). I appreciate your time, will donate, but likely will stick with 10.8.5 and wait a few months before trying again.

      • gax79up4 says:

        FYI, just put back the combo 802.11ac/BT card (from Amazon: ‘Broadcom BCM94360CD BCM4360CD 802.11ac mini PCI-E WiFi WLAN Bluetooth 4.0 Card for Apple’) but also added your beta USB kexts and the VoodooTSCSync.kext found in the DMG (aren’t these meant for post-installation? … if i could only get there 🙂 without having to ‘bootstrap’ with my 10.8.5 SSD). Here is the screen shot http://www.biodan.org/misc/hex/yosemiteBoot4.jpg with -v -x cpus=1 npci=0×2000 kext-dev-mode=1 nv_disable=1. Interestingly, it is now resuming/suspending the IOBlueToothUSBTransport before bailing out with a ‘Resetting IOCatalogue’. At least it got past the power throttle point. BTW, a correction on my earlier post- the bootable 10.10 Clover 3021 USB stick would *not* allow me to install, it would instantly return to the prompt.

        Based on what you just told me you skiped over something in the guide… Look for hfs….

    gax79up4,
    Update your bios to F7. I have the same motherboard and have sucessfully installed Yosemite using Rampagedev’s method. I just can’t get it to wake after sleep…

    I will post all my settings later tonight.
    Motherboard: GA-X79-UP4
    CPU: i7 4930K
    GPU:GV-R7970C-3GD (HD 7970)

    The clover command is asking for a Password? click enter still nothing.???
    I am lost
    .

  46. Efe says:

    Do I have to install Clover again (or some parts of it) after updating to 10.10.1?

  47. pete says:

    Again, followed this one to a T

    When it boots to clover, get options.
    I choose install from external – OS X Yosemite install

    Nothing but blank screen. Let it sit for 20 min thinking maybe i was rebooting too soon…nothing.

    Asrock x79 Extreme6 board
    2011 I7 Cpu
    16gb ram
    R9-270 Gpu

    I have never been able to get os x to boot to the install screen….from any install that I have tried – 9 different ones to date.

    I have tried several….more than 10 in virtualbox….never gotten to the install screen. Always a blank screen or the apple screen.

    Is my mobo just broke?

    Hi Rampage,

    I’m having issue installing Yosemite in my system. I was able to make the bootable USB using clover EFI v2k r3033 . I used the boot argument -v npci=0x2000 nv_disable=1 and I didn’t have any success booting. Thank’s in advance for the help!

    System specs:
    Mobo: Gigabyte Z97X-UD5H
    CPI: Intel 4790K
    GPU: EVGA GTX 760
    RAM: Corsair Vengeance 16GB 1600mhz

    I followed your guide exactly. When I boot, I get this on the screen, nothing else:

    What on earth is that all about? No options to enter boot flags or anything. Just straight into that.

    • rampagedev says:

      Need a lot more info then this. Specs OS version and more…

      • benjackson says:

        Sorry. It’s on a Gigabyte X79-UD5. OS 10.10 already running under chameleon. I’m really just trying to do the iMessage hack (booting via the USB bootloader then booting from my working install). So all I’m trying to do is get the Clover bootloader screen to show but instead it shows this.

        Not sure what else to tell you. I just re-made the USB again, I did EVERY step without fail.

        I have 2 video cards GT-640 and GTX-680. Plugged into the GT-640, which shows the UD5’s BIOS screen at startup. I then hit F12 to go to the drive selector, select the USB and then straight into this goobledegook screen. I’ve never seen anything like this. Chameleon just worked, other than fiddling with boot flags (no big deal).

        I thought it might be the video cards, tried plugging into other one, nothing showed. I also unplugged the HDMI monitor from GTX-680. Nothing I do changes anything. For instance, no different settings in the clover install – I’ve used the EFI partition and the non-EFI way. the last way I tried is following your guide exactly.

        Very frustrating that I can’t get it to do anything different no matter what I try. So that’s why I posted this screenshot.

        Thank you. Please let me know what else I can tell you, I can’t think of anything else specs-wise or anything else that’s relevant. I built this machine in 2012 and it runs perfectly, except with 10.10 I can’t get iMessage to work which is super inconvenient. Hence this attempt.

        Thanks

      • rampagedev says:

        Make sure you are using the latest bios version. Also use the gtx 680 for boot. Also make the proper bios changes but you will need csm left enabled due to your gpu.

      • rampagedev says:

        If you have not seen I launched a new website so things have been very busy for everyone here.

      • benjackson says:

        Thanks for the reply. I will try those things and report back. Note: I could not find anything in the bios regarding CSM or secure boot, but I will look again.

      • rampagedev says:

        It is in the BIOS.

      • benjackson says:

        Yes I’m aware it’s supposed to be in the BIOS. I can’t find any settings for those things.

      • rampagedev says:

        Make sure you are on the latest BIOS.

      • benjackson says:

        Got it – will do. Thanks.

        When these boards were released the next gen UEFI standard was not released.
