I have only 2 parameters in xml file: 

post-722933-0-71483500-1447540661_thumb.png

 

Is this normal?

 

I try to add only this string: 

<key>@3,AAPL,boot-display</key>
<string>0x00000001</string>

but this doesn't help.

Video card?

XML?

IOreg?

 

You need to ADD all the highlighted part in the initial post to the vanilla/stock/untouched xml.

Here is untouched xml and copy of Ioreg

attachicon.gifioreg&xml.zip

Hi Petr.

 

Unfortunately the IOreg file appears to be corrupted. Could you please, open up your IOreg locally, search for "display" and post the screenshot of the result here?

 

Also, please, specify your video card manufacturer and amount of RAM.

Here it is! And xml after adding all properties from 1st post.

attachicon.gifdevice-properties.xml

 

Hi Petr.

 

You made a few mistakes but I corrected them.

 

You are not supposed to replace

<key>PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)</key>

with 

<key>PciRoot(0x0)/Pci(0x1c,0x4)/Pci(0x0,0x0)</key>

They are separate and should remain separate. As as said initially, you just need to add what you need. Leave the rest alone.

 

The rest of your editing was not bad. :)

 

Anyway, you can see both xmls in the attachment. You can compare them for yourself.

 

You can use the content of hex_txt (also in the attachment) to add to your Clover config. It's already generated using the correct xml file.

 

Hope it works.

Thanks a lot! It works! But between 1st and 2nd stage screen goes black for 4-5 seconds and i can see only "final stage" of 2nd stage :) It takes 1-2 seconds before desktop loads.

So i see this second stage already on deskop)

macbook pro has no delay before stages. whatever thank you again!

If you would read a few posts above, you will see this exact issue being discussed. :) It's more or less "intended". Meaning a lot of PC users have it, it happens with some iMacs as well, and so far, now one knows how to fix it. And yes, more often than not, this won't happen with a laptop hack or a Macbook.

 

Anyway, glad it worked.

 

If you don't mind, I'll add your GTX 780 to the list of confirmed cards.

Of course!

 

Could you please, check the amount of VRAM in About this Mac? I think it might show 0MB right now.

 

If so, please, use the hex_txt in the attachment to fix that.

 

That was a mistake on my side. :D

I'm pretty sure hda-gfx is not in the initial tutorial. I'm not sure it's the cause of the issue. Probably not. But let's just do it exactly like it is on the first page for once.

 

So, could you please, try the hex txt in the attachment? Please, make a copy of your current one, just to be safe. And let's see if that makes any difference. Also please, try with and without PatchVbios.

 

 

@arsradu I tried the the hex.txt you sent. It went smooth on the first stage but went black for a while then suddenly reboots. I've tried with and without PatchVbios and I get the same blank screen and reboots. Well, maybe I'll have to stick with the loading bar at the center for a while until I figure out how. Thanks for your time. Still looking forward to follow you though.

Could you please upload your Clover config.plist? You can remove the serials in SMBIOS since I'm not interested in that.

Center loading bar is still a step forward. Let's see if we can get the logo as well.

Hi there

 

A few things I don't think you need. And a few things that might fix the issue... So let's see. We can only try.

 

1. Boot - dart=0. Do you really need this? Probably harmless. But just asking.

2. Boot - rootless=1. Since you set values in Rt Variables, you don't need this. It's also obsolete.

3. GUI - screen resolution is empty. Please, try to set your resolution. And try to do the same for the OS X (in System Preferences)

4. Graphics - I'm not sure it's a good idea to inject Intel & nVidia, both at the same time. Do you even need to inject anything for your card? Just asking...

 

Also, as an advice: you might want to remove some info in Rt Variables. :) I'm not interested in that. But I'm pretty sure there are other people who are. So...it might be a good idea to either remove that or use fake info.

Hey guys. I've got an issue that may or not be related to this one, but I do know for sure that I don't have a second stage boot logo or loading bar, so hopefully fixing that will help fix my issue.

 

After booting through the first stage (takes a matter of seconds off my SSD in UEFI boot mode), I'm greeted with black screens on all four of my monitors (GTX660 driving three, GT430 driving the other one) and it just hangs there for a good couple of minutes. Once that passes and my screens come back, I'm at the desktop and everything is business as usual.

 

Think this might be fixable by correcting boot logo? I'm not all that interested in the boot logo, really, I'm just tired of twiddling my thumbs while I wait for my more-than-capable machine to reach the desktop

Well, you've got 4 monitors to drive out of 2 graphic cards, which are not from the same generation and not really similar in performance. :) Which is not easy. For the boot logo, if the monitors are different resolutions, that might also be why you don't get any logo whatsoever.

 

Also, as an advice, you might be better off removing one of the graphic cards (I guess the GT 430 would be the less powerful one of the two) and getting some sort of adapter or something to power the 4th monitor, if you really need that many monitors. :) The difference in clock speed and performance might be one of the causes, if not THE cause of you waiting so long. Basically they're out of sync. And I might be very much wrong, but instead of pushing your system up and helping it perform better, you're actually dragging it down, by adding that extra card.

 

Anyway, to answer your question, no, I don't think this will fix anything for your setup. BUT there is only one way to find out. Take all the necessary precautions and give it a try.

 

Also, if you want to fix your second stage boot logo (issue described on the first page), what I would do is this:

1. remove one of the cards and choose the more powerful one (would be the logical approach) :D. You can always chose the less powerful one, but I don't really think that's gonna help much, if at all. :))

2. unplug all the monitors but one (you can pick which one you want).

3. give it a try as it is, to see if you have this exact issue or you have another one.

4. if you do, try the steps in the tutorial and see if that makes a difference.

5. if it does (hopefully) you can try adding up monitors (you might need to set multiple monitors as default, which I never tried, since I only have one, so I don't know if it would work, but it might) and see what happens.

 

Bottom line: start small. Start with the minimum points of failure. And add up elements to the equation. See how that affects the overall performance.

 

For this thread, a multi-monitor, not to mention multi-graphics setup is a a bit off-topic. :)) Since the tutorial is neither meant for, nor tested, under either one of those conditions.

Hey, thanks for the info either way. I'm gonna give it a shot. I know it sounds nuts but I really need my screens… but I might be able to get away with three if I set them up differently. How you like this for a setup

Hooooooolyyyyy {censored}, man!! Why the hell didn't you say it like this from the beginning?

 

So...for this setup, you need:

1. 5 pairs of eyes

2. roughly 5 pairs of hands. but 6 might come in...handy. :)

3. a ginormous brain...or two...

4. a lot of weeeeeed. :))

 

And "nuts" is not that nuts anymore, when you put it like this. :))

 

Anyway, back to the topic, man, I'm sorry, but I really don't know what else I could suggest you to try, aside from the things I mentioned in my previous post. Kinda hard to debug such an issue when you have sooo many options for failure. :))

 

Still, I think the basic rule remains the same: start small. Cause damn you have a lot to add up afterwards!

The song's not bad. :) I can PM you a few thoughts on it, if you want. My music expertise, though I am still very much a geek, is not as limited as you might think. :) Still, for this thread, it's not really the place to do that.

Edited. You will need to add the exact maker for your graphics card and the ROM version (you can use GPU-Z on Windows for that, for example).

 

Also, you will need to use this xml to update your hex file and get the hex code to insert into Clover, as described on the first post.

 

Don't forget to make a backup of your current config.plist on a memory stick to be able to boot in case something goes wrong.

      I have an old Hackintosh that I have brought back to life. An ASUS P5KPLAM-SE mobo, Intel Core 2 Quad, with a Sapphire HD 5670 1GB graphics card. It used to work just fine on High Sierra 10.13.3 (I think it was .3) However I only used the DVI port. Updated to 10.13.6 and with AMD kexts rollback to the previous versions I got everything o wrk just fine: boot, HDMI video, HDMI audio etc etc. The only problem I face is that my USB keyboard and mouse freeze/hang seemingly very random... I can not seem to get it right. Unplugging and replugging the USB device makes it work again, sometimes for a few seconds sometimes for an hour ... No idea what's wrong... Have tried tons of options in clover, USBInjectall.kext with port limit patch, whatever I could find... Would there be anyone out there who would have an idea of what could be the problem?

      Update: Now running Mojave! Thanks to mojave2core! Yeah   Still using C2D in 2019!
      Inserted a nice and cheap GT710 that is not relying on nVidias Webdrivers and runs OOB under Mojave.
       
      Nice, seeing High Sierra running on this old but capable system! It rocks with a new ASUS GT1030
       
      Config:
      Gigabyte EP43-DS3L
      Core2Quad Q9300
      6 GB DDR2 RAM
      Asus GT1030 2GB
      Sandisk SSD 128GB
      TP-Link AC1200 Wifi USB
      Inateck KT4006 USB 3.0 PCIe (No boot)
       
      SMBIOS: iMac14,1
      Clover: 4297  4360
       
      A good deal of DSDT editing was necessary to get this machine to boot High Sierra but finally it works flawlessly, even sleep and wake!
      You NEED to have the DSDT put in place for installation because otherwise macOS doesn't recognize the SATA ports.
      There are a few important BIOS settings: SATA hast to be set to AHCI and "native" and HPET has to be run "64-bit", I'd recommend to disable IDE and the serial and parallel port.
      For the GT1030 nVidia Webdrivers are needed, have to boot with nv_disable=1 until you have them installed.
      You have to install Clover in legacy mode because this old fella does not support UEFI.
       
      Only downside: The so often recommended Inateck USB-card isn't recognized by BIOS, so you cannot boot from it. It works perfectly within macOS though, have the ac-Wifi connected to it.

      Making a High Sierra USB Installer Entirely From Scratch in Windows
      This is a proof of concept tutorial, to show it's possible to create a vanilla High Sierra installer, entirely from scratch, in Windows (even without App Store downloaded "Install macOS High Sierra.app" from a real Mac ).  @PikeRAlpha's link to Apple's Software Catalog provides us with all the URLs necessary to download the needed files directly from Apple instead of some dubious source from the internet...
       

      Pre-Requisites
      8GB or larger USB drive.  Edit: Recommend 16GB or larger for macOS Catalina 10.16 Boot Disk Utility v2.1.2017rev021b from @CVAD TransMac (free 15 day trial) Paragon Hard Disk Manager Free Download Installer Files Directly from Apple
      1)  Browse Apple's Regular Software Catalog and find the URLs to download the following 6 installer files...
      BaseSystem.dmg BaseSystem.chunklist InstallInfo.plist InstallESDDmg.pkg AppleDiagnostics.dmg AppleDiagnostics.chunklist (Hint - search page for "InstallESD" to find its URL and others nearby)

      to a folder named "SharedSupport" on your Windows NTFS drive.  A browser download manager (eg Chrono for Chrome, dTA for FireFox) is handy since InstallESD is >4GB ---> allows you to pause/resume interrupted download...

      2)  Rename InstallESDDmg.pkg to InstallESD.dmg
      3)  Edit InstallInfo.plist with WordPad/text editor to remove the chunklistURL and chunklistid keys for InstallESD, and renaming it from InstallESDDmg.pkg to InstallESD.dmg (example of edited file attached to this post)...
      Note:  You can verify the SHA1 checksum of your InstallESD.dmg and BaseSystem.dmg with the correct ones at this website.
      Boot Disk Utility to format the Installer USB and Restore OS X Base System HFS partition
      1.  Format USB with BDU & latest Clover ---> creates boot files in CLOVER partition + second FAT partition
      2.  Extract 4.hfs from \SharedSupport\BaseSystem.dmg with BDU --> save to it's local folder
      3.  Restore 4.hfs to USB second partition with BDU --->  2nd partition becomes bootable "OS X Base System"
      Paragon Hard Disk Manager to extend HFS Partition to its Full Extent
      Open Paragon Partition Manager Free and resize the second partition of the USB drive to the full size allowed.  Don't forget to apply the changes at the end...
      Transmac to Copy "SharedSupport" folder to OS X Base System
      1.  Open the TransMac program and navigate to the HFS+ Volume/Install macOS High Sierra.app/Contents folder.  Right click anywhere in the empty space on the RHS pane and select "Copy Here"...
      2.  In the next stage, select the "SharedSupport" folder we created above as the "Files and Folders to be copied to the Mac Volume"...
       
      Clover Settings
      Clover configuration is required now.  The default config.plist (in the Clover FAT32 partition of the USB) maybe sufficient to boot your machine if you’re lucky.  If not, the hackintosh-vanilla-desktop-guide has some good explanations on the various settings available and also offers sample configuration files based on CPU type.  Also, look at the Clover Wiki, Clover Instructions and Clover Configuration Thread for pointers and edit /EFI/Clover/config.plist accordingly with Wordpad or Notepad.
      The location of the important configuration files for Clover are summarized below
      config.plist--->EFI/CLOVER folder DSDT.aml with or without SSDT.aml--->EFI/CLOVER/ACPI/patched (don't need one if your DSDT is auto patched by Clover in config.plist) Kexts eg FakeSMC, NullCPUPowerManagement --->EFI/CLOVER/kexts/<osx version> or /Other. NB BootDiskUtility by default already has FakeSMC.kext installed here.  You may need to add VoodooPS2Controller for your laptop keyboard/trackpad to work. If UEFI booting, you will most likely need one of the OsxAptioFixDrv-64 drivers copied from /EFI/CLOVER/drivers-off/drivers64UEFI to /EFI/CLOVER/drivers64UEFI. If you want to use the installer to run High Sierra in Windows on VMware, you can follow my guide to set up the Virtual Machine and replace Clover's default config with EFI_Clover for VMware (which is compatible to run in VMware).  In the screenshots below, I have attached the USB Installer (in this case PhysicalDrive7) to my macOS Virtual Machine.  Reboot the system to the USB installer to install High Sierra ...
      What happens if we don't have access to TransMac or Paragon Hard Disk Manager?
      Not a problem, as long as we get "OS X Base System" bootable, we can launch terminal from the Utilities Menu to copy the SharedSupport folder over to the Installer app.  In essence, we will build the full installer app = 5GB+ on the target HD eg "Macintosh HD", by copying both the "small" installer app = 15MB (on "OS X Base System") and the SharedSupport folder from the NTFS volume (mounted in this example on /Volumes/DATA)...
      -bash-3.2# cd / -bash-3.2# cp -R Install\ macOS\ High\ Sierra.app /Volumes/Macintosh\ HD/ -bash-3.2# cp -R /Volumes/DATA/SharedSupport /Volumes/Macintosh\ HD/Install\ macOS\ High\ Sierra.app/Contents/  
      ...then start installation with the startosinstall utility...
      -bash-3.2# /Volumes/Macintosh\ HD/Install\ macOS\ High\ Sierra.app/Contents/Resources/startosinstall --volume /Volumes/Macintosh\ HD --converttoapfs NO --applicationpath /Volumes/Macintosh\ HD/Install\ macOS\ High\ Sierra.app  
      The above steps can be automated with the attached "startosinstall.command" script, which will assemble "Install macOS High Sierra.app" on "Macintosh HD" and launch the startosinstall utility targeting the "Macintosh HD" volume.  Copy/download to "Macintosh HD", then run in terminal (after attaching DATA USB with /Shared Support folder)...
      cd "/Volumes/Macintosh HD" chmod +x startosinstall.command ./startosinstall.command Updated Download Links for macOS Mojave 10.14.6_18G103
      Browse Apple's Regular Software Catalog and find the URLs to download the following 6 installer files...
      BaseSystem.dmg BaseSystem.chunklist InstallInfo.plist InstallESDDmg.pkg AppleDiagnostics.dmg AppleDiagnostics.chunklist  
      Note: In Mojave, Apple has removed the --converttoapfs NO and --applicationpath arguments from the startosinstall utility....
       
      eg to use startosinstall for the above section "What happens if we don't have access to TransMac or Paragon Hard Disk Manager?", the syntax is now
      -bash-3.2# /Volumes/Macintosh\ HD/Install\ macOS\ Mojave.app/Contents/Resources/startosinstall --volume /Volumes/Macintosh\ HD  
      This basically means that for Mojave, the default installation will always convert the target volume to the apfs file system.
