Can‘t be installed on Hynix PC601 SSD

[yantonglu]

It seems to be a common problem of PC601. Kernel panic with info "IONVMeFamily(2.1)" will be caused when installing. Just like this https://www.reddit.com/r/hackintosh/comments/fb3zah/kernel_panic_during_installation_with_dell_xps_15/?utm_source=amp&utm_medium=&utm_content=post_body which model is XPS 15

[tylernguyen]

@yantonglu

Could you try formatting the drive to 4K under Ubuntu and use the installation steps here: #43

[yantonglu]

Thank you. However, it seems that the unlucky XPS 15 user has tried 4k formatting under Ubuntu but still stuck before the installation launch...
I have checked more information and come to PC601 SSD is incompatible with highly probability...
Thank you for reply.

[tylernguyen]

Is it possible for you to try the installation steps in that issue? It's sort of a solution for the PM981 that I also thought to be incompatible. It would be great if you could confirm whether those steps work for the PC601 or not.

[yantonglu]

OK, I'll try it after I purchase another compatible SSD (SSD on my desktop is a pm981a, sigh....).
I question the solution, because I know the statement "pm981 is incompatible" is to say that something will go wrong at the GUI installation step, you at least launch the GUI installer (My bro has a 970 evo plus, and I tried to install and I success)... But the statement "PC601 is incompatible" means it will stuck before you see the GUI installer... I'm afraid that the same panic will happen after transfering installed macOS to PC601(before hacOS launch, it will run a piece of code if you add "-v")
Sorry for my messy wording... I need to improve my English...
Thank you

[zacharysalvatore]

@yantonglu you don’t need another compatible ssd to do it. You could install macOS on to an external USB stick under win10 using VMWare and mount it as a physical device.

[yantonglu]

OK, I'll try.

I do not see why launching the installer GUI has anything to do with the drive. Internal drives should be untouched until they are selected to be installed on. If the installer GUI fails to launch, I'm more inclined to believe that it's the USB's fault, most likely the EFI.

[tylernguyen]

@yantonglu
Additionally, a sanity check for this would be to create an ACPI patch to disable the drive. If the installer GUI launches with the ACPI patch but fails to load without it. Then we could confirm that it is indeed the drive's fault that the installer GUI is not launching.

The patch would look something similar to ones used to disable NVIDIA dGPU. Though it would be the ACPI path of your Hynix PC601. Though this method would require decent investigation since the GPU patches leverage the ON/OFF method built in. And I do not believe such methods exist for other devices.

@zacharysalvatore
Do you mean install hackintosh with VMware first, then mount a Windows partition and restore to it with Time Machine?
I haven't done this before, so I don't know details.

[yantonglu]

I made some progress.
I install macOS to a partition of my pc601（I made a 300M EFI partition in front of it）with Vmware，and it boot normally，so I put the EFI into the EFI partition and use Bootice add a boot entry.
Everything goes well until I reboot and try to boot the new boot entry. However，it displays “System has no boot entries...”
Help me，my friends，I think victory is in sight.

[tylernguyen]

@yantonglu
Please post your EFI.
Additionally, it looks like your EFI is not setup for OpenCanopy. Please change PickerMode to Builtin
Also, please adjust your ScanPolicy so boot entries show up.

[yantonglu]

@tylernguyen
Actually I use your latest EFI (EFI-OpenCore/EFI).
I can't understand what I need to do... I know little about PickerMode or ScanPolicy...

[yantonglu]

@tylernguyen
I will describe in more detail: I successfully added the boot entry with Bootice, and after reboot I choose it and presses Enter, but it reports the above error.

[tylernguyen]

The variables you need to configure are in config.plist

[yantonglu]

I change ScanPolicy to 0 then see the boot entry.
Apple logo displayed but when the progress bar reaches halfway it reboot, same for recovery mode.
I wonder why this time a bunch of code is not displayed... There must be a option in OpenCore, like "-v" in Clover.
Sorry to ask such a low question, but I am a rookie.

[yantonglu]

Unluckily，I boot with “-v” and see the same error.

Does this mean that everything I do is in vain？sigh...

[tylernguyen]

@yantonglu
Per the PM981 installation method, you are not supposed to install directly onto the disk. You are supposed to restore a the backup image of an already installed onto your Hynix drive. Also, do you have "ssdt-nvme.aml" and "HackrNVMeFamily-10_12_6_sec2018-001.kext" when trying to boot that drive? Please read the PM981 issue thoroughly.

[yantonglu]

You mean there is deference between a backup fully installed macOS and my “a installed macOS + a EFI partition in front of it”？You should know I have successfully installed the macOS onto the partition by VMware，it has been installed fully and can be launched normally in VMware...
So I must use paragon to backup a fully installed macOS？I don’t know how to make it without a compatible ssd...
Thank you very much.

[yantonglu]

I added "ssdt-nvme.aml" and "HackrNVMeFamily-10_12_6_sec2018-001.kext", but it still reports the same error...

Thank you very much.

I'm not sure what you mean. Per issue #43 @zacharysalvatore used Paragon to backup and then restore that image onto the drive. What steps did you do differently?

[yantonglu]

@tylernguyen
Can I make it without a external ssd? (only with Vmware)

[tylernguyen]

@tylernguyen
Can I make it without a external ssd? (only with Vmware)

It seems that one person got it working via the VMware method. See #43 (comment)

However, using VMware seems like it would just add more layers to the problem, and we want to isolate problems to just the drive in question. So I think it's better for you to use @zacharysalvatore orignial method.

[yantonglu]

I made some progress.
Now the panic turns to "AppleIntelKBLGraphicFrameBuffer", sounds related to gpu.

[tylernguyen]

Now the panic turns to "AppleIntelKBLGraphicFrameBuffer", sounds related to gpu.

Which EFI are you using? Install or Main?

[yantonglu]

Main, but for a new installation, because if I use main to launch the macOS backup from paragon, its progress bar reach half then display a prohibition flag.
Should I change to Install EFI?

[yantonglu]

At last，I use install efi and entry the GUI installer...
But there is no my ssd in the disk utility...
I think I will use this EFI to try backup method.
Thank you for help.

[yantonglu]

Now：
Install EFI or Main EFI + backup macOS = prohibition flag.
Install EFI + installation image = GUI installer but can’t detect ssd.
If I add nvmegeneric.kext，GUI installer cannot be launched.

[tylernguyen]

@yantonglu

Sorry. I'm quite confused. Why do you need to launch the installer? macOS should already be installed. You just need to restore it onto the PC601. Again, please read issue #43 carefully.

[yantonglu]

When I try to launch the restored macOS，it display a prohibition flag.

[tylernguyen]

When I try to launch the restored macOS，it display a prohibition flag.

Ok, if it's the install EFI, it should be in verbose mode. Can you show the logs?

[tylernguyen]

Also, with the EFI:
Install OpenCore debug: https://github.com/acidanthera/OpenCorePkg/releases
Change debug target the 67
After each boot, an OC log should appear in the EFI parition now. Please also upload that.

You're booting the installer?

[yantonglu]

Ah，I think it is a installed macOS！I download it from a tutorial，so you mean actually it is a installer？
So I should change to a origin installed macOS？If so，can you provide me one？I have no Mac. Thank you.

[tylernguyen]

@yantonglu
I do not have one. You need to create one yourself, per @zacharysalvatore 's post. Here are the steps again to be clear:

1. Install and setup macOS on another drive. Per the PM981 post, you can do this via VMware, please refer to that issue.
2. Backup and restore that drive onto your PC601
3. Add ssdt-nvme.aml and HackrNVMeFamily-10_12_6_sec2018-001.kext to your EFI (make sure to edit the aml with your proper nvme controller's ID) and boot the PC601 (which at this point, should already be restored to the installed macOS).

[yantonglu]

I know the steps.I have found some source.
Thank you very much.

[yantonglu]

I restored a true backup macOS and switched to hard disk boot.
Prohibition flag still.
And report dumped turns strange.

@yantonglu This is with the nvme kext and aml patch added? Also, remember that the aml needs to be modified to your nvme path.

[yantonglu]

Yes，I have finished everything.

[tylernguyen]

Those look like OpenCore logs. Could you show the verbose logs also?

[yantonglu]

I can't dump the report so I shot the panic:

[tylernguyen]

@yantonglu
Could you share a zip of the EFI you used to get that error?

[yantonglu]

I have changed my ssd to 970 eve plus and successfully install...
Thank you for your great help!

[yantonglu]

There is a small question: is it normal that the graphic memory is only 1536M?

[tylernguyen]

There is a small question: is it normal that the graphic memory is only 1536M?

Yeah, it’s completely normal. You can patch to 2048MB using unifiedmem but it's not recommended by WEG.

Hey @yantonglu, will you please help me if you have got this working? I have same SSD and completely lost in between of this long thread. Can you please sum up things for me, it will be a great help?

[yantonglu]

@way2ezee Actually I never solve the problem, and now I switched to a true MacBook Pro, so I lost not only the hackintosh device but also the skill, haha. Sorry for I can not help you.
