[AMD] 10.7.3 Guide - Experimental Only

Guide Revision 003 - 20042012

Written by Devout

 

CHANGES are in Green.

 

Introduction

 

Welcome to the tutorial to get your 10.7.3 running. Before we start, I'd like to make it clear that this tutorial is based on a kernel that is still being developed, and future changes to the tutorial will occur. Additionally, not everything works right now so you'll just have to see if your machine is supported and that you want to see if it's capable of running Lion. Please do not install this if you're planning to use the machine a lot, as there are still problems with applications crashing, and I don't want you to be frustrated. Use my Snow Leopard Guide if you need a reliable machine (link in FAQ).

 

It's currently impossible to install Lion using your AMD machine, unless if it's a distribution. Please use Methods 1 to 3, depending on what access of hardware you have. Additionally, these range from being easy (1) to hard (3). The Retail Lion installation requires an Intel processor, and you won't be able to bypass this on an AMD machine, hence you might need to use Methods 2 or 3.

 

Installation - Setup

 

Method 1 - Easy

Required: 10.7.3 DMG from Mac App Store + Existing Intel Hackintosh or Mac Hardware

  • Using your exisiting Intel hackintosh machine running Snow Leopard 10.6.6 + or real Macintosh hardware, Install 10.7.3 Retail DMG to an external harddrive OR take your your exisiting hard drive and connect it to your machine using an external exclosure if needed.
  • Once it's installed successfully move on to STEP 1. (Follow directly, don't restart, reboot).

Method 2 - Moderate

Required: iATKOS L2, ShowAllFiles, Existing Snow Leopard

  • Using your existing AMD Machine running Snow Leopard. Mount iATKOS L2 DMG, and let it verify.
  • Once verified, you'll need to ShowAllFiles, before you can see the contents of the DMG.
  • Once ShowAllFiles has been enabled, open the DMG.
  • Locate: System/Installation/Packages/OSInstall.mkpg and open the file.
  • This is the Lion Installer, continue till you can customize the install. Make sure you select the correct Installation Harddrive, as you need to be careful you're not reinstalling over Snow Leopard or other important partitions.
  • Customize the installation, however you like. Not much of this will matter, leave the default selected items. Additionally you can untick Bootloader, if you want it to be a bootable USB (Scroll down for this). Install any network/sound drivers you need.
  • Let the installation continue and install, let it finish, and you'll have Lion installed.
  • Once it's successfully installed move on to STEP 1. (Follow directly, don't restart, reboot).

Method 3 - Hard

Required: iATKOS L2, iHazard 10.6.2, ShowAllFiles, Existing Snow Leopard

  • Download VirtualBox https://www.virtualbox.org/, and install.
  • Download iHazard 10.6.2 ISO.
  • Create a VirtualBox Profile and configure profile, making sure you untick Special EFI, and then load iHazard 10 6 2 ISO.
  • Run the Virtual Profile you created and install 10.6.2.
  • Once successfully Installed, restart.
  • Try and run Snow Leopard with the following Bootflags:
  • -v arch=i386


  • If it works, proceed. (If not, reply to topic).
  • Remove iHazard 10.6.2 ISO from the Virtual Profile.
  • Attach iATKOS L2 DMG to the Virtual Profile, and open it up from within Snow Leopard.
  • iATKOS should come up.
  • You'll need to ShowAllFiles, before you can see the contents of the iATKOS.
  • Once ShowAllFiles has been enabled, open iATKOS.
  • Locate: System/Installation/Packages/OSInstall.mkpg and open the file.
  • This is the Lion Installer, continue till you can customize the install. Make sure you select the correct Installation Harddrive, as you need to be careful you're not reinstalling over Snow Leopard or other important partitions.
  • Customize the installation, however you like. Not much of this will matter, leave the default selected items. Additionally you can untick Bootloader, if you want it to be a bootable USB (Click here for that). Install any network/sound drivers you need.
  • Let the installation continue and install, let it finish, and you'll have Lion installed.
  • Once it's successfully installed move on to STEP 1. (Follow directly, don't restart, reboot).

STEP 1:

  • If you've enabled ShowAllFiles yet, do so now.
  • Open the root of the freshly Installed Lion.
  • Replace the hidden (but shown up) mach_kernel with the one from here. (http://www.osx86.net...md!!!!!!!!.html) (Use V4).

STEP 2:

  • Install Chameleon using Chameleon Wizard on the harddrive. Additionally, you can choose to install this on a USB stick so you have a bootable USB.

STEP 3:

  • Reboot and configure your BIOS and make sure the drive that the partition is on is set as AHCI.
  • Reboot to save your BIOS settings and you should be in Chameleon. (If you created a bootable USB with Chameleon, make sure you use Boot Priorty for your USB to load before Hard drive or press F8 (button varies), to boot the USB directly first).
  • Type in the bootflags

-legacy -v arch=i386 npci=0x3000

 

Step 4:

  • It should load, and you'll be greeted with the Welcome Screen. You've now got a running machine of Lion!
  • Proceed to install graphical, wireless and sound drivers if they're not already working. (If you used iATKOS L2, upgrade to 10.7.3 through combo updater and then replace mach_kernel and finder again, or you'll need to use another Mac or MacDrive to replace these files).
  • Confirm your motherboard processor! BY REPLYING!

FAQ.

 

Q. Do I need to replace mach_kernel if I update Lion?

Yes, you'll need to do this if you're coming from iATKOS 10.7.2 to 10.7.3. You'll need to do it for future updates as well as 10.7.3.

 

Q. Is it possible to replace mach_kernel and finder in Windows?

Yes, with MacDrive.

 

Q. I get stuck at "AppleUSBOHCI::CheckSleepCapability - OHCI Controller will be unloaded across sleep" in verbose mode.

Make sure your hard drive is set to AHCI mode in BIOS.

 

Q. I get stuck on [PCI Configuration Begin]?

Make sure your use either npci=0x2000 or npci=0x3000.

 

Q. I get stuck after [PCI Configuration Begin] or RTC: Only Single Ram Bank (128 bytes) or FakeSMC?

Your motherboard has problems with USB Legacy so unplug the keyboard and mouse and see if you can boot, unplug them after you press enter after inserting your boot flags in Chameleon, you can also try by adding the bootflag: USBLegacyOff=Yes

 

Q. Finder doesn't work?

The kernel is only capable of 32 bit mode, meaning you'll need to use the Lion DP2 Finder which can be downloaded here. Replace System/Core Services/Finder.app. You'll need to replace this everytime you update Lion to a newer version.

 

Q. -v Sometimes it doesn't load? Stuck after DMOS has arrived.

It freezes sometimes, you'll need to use -x bootflag to run safe mode.

 

Q. Does iCloud work? My Ethernet is en0, deleted Network Interfaces.plist, but still doesn't work?

iCloud/Facetime doesn't work with self-compiled kernels. Appstore will work with EthernetBuiltIn=Yes bootflag.

 

Q. Why do applications stop opening after X minutes? (Typically 10).

Kernel bug, should be fixed in the future. READ BELOW FOR TIPS!

 

The reason why applications are not functioning after 10 minutes is because Xpchelper has a bug and it's sending a lot of information to ReportCrash and it's basically nuking the system, hence system core services applications don't work after a while.

  • You can remove ReportCrash in (sys/lib/coreserv/reportcrash)
  • Force Quit XPCHELPER everytime you launch a system core service application like Safari, App Store, Calender, FaceTime etc.

It won't fix it, and it will still stop working, but this prolongs the availability of opening applications and using your system for more varied tasks.

 

Q. Do you have a Snow Leopard Guide?

Yes!, you can find it here (AMD): http://www.insanelym...howtopic=253767

 

Bootable USB

  • Open Charmeleon Wizard
  • Install Charmeleon latest build to your USB stick
  • Once completed it's ready to be used. IMPORTANT!=(When using this to boot you will need to press enter so it loads mach_kernel into the userframe before it can load futher, it'll tell you to press any key to continue because mach_kernel is not found, but once you type bootflags and try to load again, it'll work.)

Nice guide mate!

After the install and everything, boot hangs on "AppleUSBOHCI::CheckSleepCapability - OHCI Controller will be unloaded across sleep".

Any idea?

 

Sounds really strange but unplug mouse and keyboard and booting and are you sure your drive is set to AHCI also in BIOS?

 

update: going to see where I get stuck when my drive is not set to AHCI. BRB :)

update 2: Yepp it gets stuck there when my drive is set to IDE, instead of AHCI.

update 3: Added some more FAQs.

I replaced the original kernel of the dmg AppleStore for this supposed legacy.

 

Using rboot retail dmg + "modified" and the system was for the installation and completed successfully!

 

however now the machine does not start the installation ..

I tried many flags but nothing seems to work ..

 

ps cpu: fx-8120

 

if the boot to the installation worked perfectly because it should not be starting now that is already installed?

Thanks for your kind reply! : )

 

Now the situation is kinda hairy, let me explain;

 

I've used your Method 2 to install Lion. I had snow leopard installed on a 2.5" HDD which connected to my computer via conventer "SATA/ATA/IDE TO USB" kind of one. So snow is running on a 2.5" IDE external USB device.(40GB :P)

 

Because I'm out of hardware, I installed Lion on a IDE driver which connects to the computer in the same way, with a conventer. So I'm trying to run Lion from a USB connected 3.5" IDE (30GB :P) device. When I plug it to my motherboard via IDE, It hangs the same line and waiting for the root device. (appleusbohci) I checked for my bios and I guess I can't have my IDE drives as AHCI. (My chipset is AMD 740G and SB700)

 

But I still have a Snow Leo up and running. Isn't there some kext I can add to the Lion drive? I did some tweaking for installing Snow Leopard but they are not working on Lion.

 

 

 

Edit: I've removed IOUSBFamily.kext and IOUSBMassStorageClass.kext and now this happens. (Uploaded an image)

Hmm, I would try to replace the mach_kernel with v5 again, just incase. I haven't heard anyone successfully installing Lion using rboot. I would suggest you get the kexts for IOPCIFamily, RTC, FakeSMC, Evoreboot, Disabler and see if it helps.

 

This method of installation isn't quite clear to me, so I'm not sure if I can help you any forward, other then recommending this. Sorry.

 

Works with AMD Athlon X2 5400+ BE on Asus M2N32-Sli (Nforce 590) with v4 kernel, Sapphire Radeon 4870 512mb.

 

Thank you :-) Added to confirmed motherboards + processor.

That would where "AppleUSBOHCI::CheckSleepCapability - OHCI Controller will be unloaded across sleep" would pop up, if it wasn't for waiting for root device. I've not found a way to run it in IDE configuration, I've only found that switching it to AHCI worked. Sorry.

Hey don't be sorry! :) I just wanted to ask: I'm booting an IDE device on USB. Does it really matter wheter it's IDE or SATA? Shouldn't it recognized as usb drive? Maybe i should find the right USB kexts or modify one? What do you think?

 

Thanks!

I'm not sure, I haven't tried. I know that if it was a USB hard drive it should be recognized as a USB device, as I've done this with a memory stick (for testing), and it did load! took x 3 times longer to install and boot but it did work. I think the IDE drive is a problem as it's been configured internally as IDE hence it just won't be able to boot Lion, however I don't have evidence to back this up but I think it won't work boot. I'm not sure there are any kexts that patch this, but I'm not aware of any from my experience. I originally had my Sata drives configured as IDE and it didn't work, stopped at same point but as soon as I switched to AHCI, it worked.

Good! I'm trying to make it more stable atm, by tweaking some system files. Moving reportcrash has increased the duration before apps crash by another 10 minutes, until it refuses to load anymore applications or move files. I'm going to do some more research and see what I can find out.

Hello, and thank you very much for this guide.

 

Do i have to Install some extra kexts like FakeSMC, NullCPUPowerManagement for AMD or iAtkos does it automatically? :)

I'll try to install it on my MBR HDD.

Hey i Installed it, and installed all of my kexts.

The result was stuck on this error.

Then i removed my audio and evoreboot kext, and it still stuck on this error?

Can someone help me? Thanks.

My SATA is AHCI.

Remove all the custom kexts you have installed and then try booting with these boot flags : -legacy -f -v npci=0x3000 arch=i386 . It should boot up, boots up for me at least when I remove all the custom kexts that I've added :)

Also there is a rare error, which my motherboard has where my keyboard just can't be plugged in unless I use bootflag USBLegacyOff=Yes. Try unplugging your keyboard after entering bootflags and pressing enter and then unplug. Strange, but I've stalled there numerous times. Also custom kexts shouldn't be used but Evoreboot didn't effect my installation, but you could have some that may be causing a problem. Also your motherboard might has different setting slots for Drives 1 - 4, Drives 5 - 7. Maybe you set AHCI to 1 - 4 but your drive is connected to the 5 - 7 slots, so in theory it's not actually AHCI?

 

Here's some of the custom kexts I've installed:

  1. FakeSMC.
  2. EvoreBoot.
  3. Disabler.
  4. IOPCIFamily.
  5. RTC.
  6. Realtek RTL.

  • ATI5000.kext configured - For my 5770
  • Atheros Fix - for wireless card (D-LINK G520 REV. B4)
  • VoodooHDA - but keyboard has a built-in sound card too (native) so I don't use motherboard sound card.

Also guide updated, my system seems more stable. See FAQ.

"Using your existing AMD Machine running Snow Leopard"

 

Right now I'm on Leopard, do you think I can start the installation or I need to install Snow first?

 

 

 

Sorry if this is a stupid question

 

Thanks:)

Think you're fine just make sure iATKOS L2 is used, if you can open the OSInstall.mpkg file, then I'm sure you'll have no problems :D

Ok I fixed that custom kext error by just repairing permissions using Disk Utility and then ran System Utilities in ########. That seems to solve the whole custom kext for me :D .

 

Deleted the report crash from core services hopefully I'll be able to open apps after 10 min :)

my grafic card is ATI RADEON HD 5770 1GB

what would b my

ncpi=0x????

and also the Kernel Flags

"-legacy -v ncpi=0x????" can b edited in any .plist file and keep it permanent? insted of typing it every time while booting?

Method 2 install worked on ASUS M4A88T-V EVO/USB3 motherboard and AMD Phenom II X4 955 Black Edition processor.

Here's some troubleshooting information you can add to your guide if you'd like.

 

Enabling hardware sensors in the iAtkos L2 install can cause FakeSMC to kernel panic. To fix this, simply remove FakeSMC.kext from S/L/E (note that this of course disables hardware sensoring capabilities).

 

Instead of typing npci=0x2000/0x3000 as a boot flag, simply install the IOPCIFamily patch in the iAtkos L2 install.

 

If your system hangs at "DSMOS has arrived", add -legacy to your bootflags.

 

I had some issues with installing Chameleon, which was odd since I've never had trouble with it, but I figure it's due to my EFI partition, so I'll have to format that if I install Lion again.

 

However, I'm going to continue to wait for a more stable kernel. Thank you for this guide, it was a tremendous help.

      Hello Everyone,

      Trying to get Hardware Acceleration working on my Hackintosh (HEVC Support) however I am such a noob, OpenCore is very new to me and would love some support.
      I have included screenshots and the EFI that is currently working on my System, I have USB 2 & 3.0 all working, however, the only thing I can fault is my GPU not being hardware acceleration enabled.

      Final Cut Pro X - Recognises GPU
      VideoProc - Doesn't recognise anything.
       
      (I am running the latest version of OpenCore 0.5.9)

      Things I've tried: I tried following the post https://www.tonymacx86.com/threads/catalina-10-15-2-update-lost-hevc-h265-acceleration.288563/ - No Luck
      I have also tried: https://forums.macrumors.com/threads/activate-amd-hardware-acceleration.2180095/page-53?post=28255048#post-28255048 - No luck either!

      My friend online tells me I shouldn't need such Kext as he has the same build as me but when I load his EFI on my system it boots with no USB 2 or 3.0 (I'm keeping his EFI off here as I've uploaded mine.)

      Please note: I appreciate all (any) pieces of advice and please do bear in mind that I am a noob and may need whatever you say simplifying as I can get easily confused.

      Radeon RX 580 8 GB graphics card on macOS High Sierra (as of 10.13.6), Mojave and Catalina on the P55-USB3 board: excellent performance with acceleration (Metal) OOB, no need for drivers (kexts), with 3 drawbacks, one has to do with the boot of the operating system (a solution is proposed), another with the number of rear connectors enabled (a solution is proposed) and another that only affects to one phase of the Mojave or Catalina installation (without clear solution for now).

      I have placed the XFX AMD Radeon RX-580 P8DFD6 8GB Triple X Edition GDDR5, 256BIT, DVI + HDMI + 3DP graphics card on a 10 year old motherboard (Gigabyte P55-USB3) in order to update the hackintosh to 10.14 Mojave and 10.15 Catalina because the card that I have used in past years, Nvidia Geforce GTX 750 1GB, has stopped working after 10.13.6 High Sierra since this was the last version for which Nvidia published the alternate web drivers that were necessary for the card to work well with graphic acceleration.

      The new RX 580 card needs considerably more space than the old one although it fits perfectly in an ATX case, and requires an additional power connector. It has 2 big fans that most of the time are stopped, at least in my case. In macOS it works perfectly, even with Metal acceleration, without additional drivers and without extra settings in Clover. But it has drawbacks that I comment below.

      Alterations during startup

      During the boot of the operating system, when the screen goes from the basic driver to the AMD driver, 2 artifacts appear randomly, they are very short in duration (from one to a few seconds):
      Very short flashing white screen that may or may not be accompanied by purple lines The fans runs for a few seconds (the noise is clearly audible). This behavior is solved with the installation of 2 kexts, Lilu and WhateverGreen. Lilu is an extension created by acidantheraand vit9696 among others whose function is to help to patch kexts, processes and libraries during macOS boot. It is accompanied by specific plugins for the task required, for example WhateverGreen that injects necessary patches for certain AMD, Intel and Nvidia graphics cards. It is mandatory to have both extensions together, one of them separately does not correct the problem.
      I have installed Lilu 1.4.4 and WhateverGreen 1.3.9 in the EFI/CLOVER/kexts/Other folder of the EFI partition and artifacts have disappeared. Remember that these 2 extensions are not necessary for the card to work properly, if you tolerate those very brief distortions of the screen or the noise of the fans running for a few seconds, you can live without Lilu and WhateverGreen.

      Note: authors recommend that when using Lilu and WhateverGreen with Radeon cards, NO graphic settings have to be added to Clover (Inject ATI, etc.).

      Note: these alterations, especially the brief white screen and less frequently purple lines and fan noise, are also seen in Windows and some real Macs with the same card.

      Alteration during macOS installation

      Boot from USB > Clover menu > Install macOS from Install macOS Catalina > screen works fine
      Boot from USB > Clover menu > Install macOS from MacintoshHD > black screen
      Booting from USB > Clover menu > Boot macOS from MacintoshHD > screen works fine.

      In the first and third stages, screen works fine. In the second stage the screen goes black although the installation continues. The user has nothing to do at this moment so you can leave the PC working until the Clover menu is shown again, the screen is recovered, the initial account options can be configured and you can enter into the newly installed system with correct resolution and acceleration.
      This behavior is not corrected even by placing Lilu and WhateverGreen into the USB device. At least in my case I have not found a solution for it. Yo can install macOS perfectly with that drawback of not seeing how it progresses during the second phase of the installation.

      Only 2 connectors of the 5 available work

      This card has 3 Display Port (DP) ports, 1 HDMI port and 1 DVI port. In my case, only 2 DP work, those that are further from the HDMI connector. It is enough if you use a single monitor or 2 monitors that can be connected by DP. But if you want to have 3 or more connected devices or some of them only have HDMI, it is necessary to enable the 5 connectors or at least 4 of them since the DVI is obsolete and does not allow resolutions as high as DP and HDMI.
      User foxbox has proposed a solution in a thread titled [Solved] Sapphire RX 580 Nitro + SE | black screen on HDMI and DVI. Must inject from Clover a modification to the Orinoco framebuffer (which is used in the RX 580 card) so that the 5 connectors lack a fixedly assigned address and, instead, receive it dynamically. This change is made from the KextsToPatch section of Clover. Read the post from foxbox.
      This has to be accompanied by 3 changes in the Graphics section of Clover: Orinoco in FB Name / Inject ATI / 5 in Video Ports. I have tested this solution in macOS Catalina and it effectively enables the 5 ports of the card but, since I only use 1 monitor, I have removed it and I am with Lilu and WhateverGreen.

      Hello there!
       
      TL:DR; I built a Hackintosh system using the OpenCore Vanilla Desktop Guide (running Catalina 10.15.4) and I use an AMD Ryzen 1600 CPU and Radeon RX 5700 XT GPU. All works well except my displays are very blurry and it feels like I’ll get a headache if I try to look at the screen for very long. The picture quality is noticeably worse than Windows or Linux. What can I do to fix it?
       
      --
       
      Let me start off by saying that this is my first hackintosh build. I based my build on the Opencore Vanilla Desktop Guide at https://khronokernel-2.gitbook.io/opencore-vanilla-desktop-guide/. I’m running macOS Catalina 10.15.4.
       
      So I finished installing macOS after slowly and carefully taking about 8-10 hours to go through the guide yesterday and make sure I did everything properly. It paid off - it has been solid as a rock. However, there is one problem that is currently bugging me to no end - my displays are very blurry. This seems to be independent of any application or display resolution. My dock icons are blurry, the system text is blurry, app text is blurry (like in Slack, Safari, Notes, etc). This does not occur in Linux or Windows when using the same screens. 
       
      Also, as a test, I hooked up my girlfriend’s MacBook Pro to the same two screens, and the monitors are crystal clear again, just like they usually are in Windows. This leads me to think that my EFI may be configured improperly or my system may be missing some software or a kext that enables the displays to show a sharp image. I attached my EFI folder and my config.plist file for reference. 
       
      EFI setup:
      ACPI: SSDT-EC-USBX-AMD.aml Drivers: ApfsDriverLoader.efi OpenRuntime.efi VBoxHfs.efi Kexts: AppleALC.kext AppleMCEReporterDisabler.kext Lilu.kext RealtekRTL8111.kext VirtualSMC.kext WhateverGreen.kext (version 1.3.8) My boot args are: "npci=0x2000 agdpmod=pikera keepsyms=1 debug=0x100 alcid=1"  
      System specs:
      Ryzen 5 1600, no overclock or anything special Corsair Vengeance Pro RGB RAM, 32GB total (2x16GB DDR4 dimms running at 2400MHz) XFX Radeon RX 5700 XT RAW II 8GB GPU (this is listed as a PCIe 4.0 GPU, could that cause issues since my motherboard is PCIe 3.0 only? Works great in Windows/Linux) ASUS Prime B350M-A motherboard Samsung PM961 256GB NVMe SSD  
      My monitors:
      Samsung U32J59x (32” @ 3840x2160) ASUS MX279 (27” @ 1920x1080) The blurry issue also occurs when I plug directly into my 58" Samsung 4K TV.  
      I’ve already tried these steps:
      Adjusting monitor “sharpness” settings, totally unbearable at “0” but still looks pretty bad even at “100” Trying a bunch of different resolutions in the “Display” preferences. On the 4k monitor, the only one that looks any better is the 1920x1080p option, but then I have far too little screen space left. Using SwitchResX, no different than using different resolutions in the regular Display preferences Using subpixel antialiasing in the terminal with no noticeable difference, even through reboots Turning on/off AMD FreeSync on my 4K monitor — if I turn on FreeSync, the display lags and stutters, and quality is not any better. Also tried turning on/off “game mode” but that had no difference. Tried switching DisplayPort version between 1.1 and 1.2 in monitor settings (on 4K monitor) Checking my BIOS settings, such as making sure CSM is off, against the OpenCore guide that I used to make sure everything was correct  
      Does anyone else have some other ideas that could help to correct this issue? Any ideas would be greatly appreciated. Thanks in advance!!

      A few days ago I faced a problem - installed ocquirks and it somehow broke my prelinked kernel. System won't boot then, and I spent more than a day restoring from the netatalk  backup to copy working prelinked kernel directory from the backup to the s/l
      So, my question is - how to relink prelinked kernel without that? I found boot args -f UseKernelCache=No but it didn't work. I was able to boot to the recovery, if that can help.
