A "Rare" kernel panic?

[few]

My Computer supports only USB 1.1 EHCI and I'm trying to install macOS from a single 7GB USB stick. I also had more kernel panics but they were kernel extensions based. Now after fixing those kernel panics, I get kinda "Rare" error:

Maybe USB based Kernel Panic?

Hardware:

Intel Core 2 Duo E6850 (Conroe)

NVIDIA GeForce 9600 GT

7GB DDR2

ASUS P5KC GREEN Motherboard

Gigabyte Chassis Poseidon Silver case

 

Additional Information:

I'm trying to install El Capitan on a Legacy Machine.

I have tried USB mapping and it didn't help.

My BIOS doesn't support Intel VT.

 

How can I fix that?

Yes, ElCapitan is possible here. 

May be you forgot to use FixUSBOwnership in clover config.plist?

I'm using OpenCore and the closest match to the FixUSBOwnership is ReleaseUSBOwnership, would that be ok too?

Intel E6850 being Conroe, it lacks the SSE4.1 instructions set required for macOS (Sierra 10.12 and later). As such OS X El Capitan 10.11.6 (kernel 15.6.0) is indeed the last possible version you can install and run on this old system of yours.

nVidia GeForce 9600GT is Tesla and should be expected to work OOB; no need for the nVidia Web Driver therefore no need for boot arg nvda_drv=1.

Please note that EHCI is USB2.0 whilst USB 1.1 is UHCI: https://en.wikipedia.org/wiki/Host_controller_interface_(USB,_Firewire)

But it's surprising that a Conroe platform would not provide support for USB2.0 port. Did you check your USB settings in BIOS setup? Should be set to enhanced/fast, not compatible/legacy.

 

Don't hesitate to post a zipped copy of your OC EFI folder.

Sorry for late reply, here you go.

So you obviously have USB2.0 controller/ports. What options does your BIOS offer for USB2.0 Controller Mode: FullSpeed and ???

HiSpeed

Go for HiSpeed, that's for USB2.0 speed when FullSpeed is for USB1.1 speed.

As always, remember the golden rule: RTFM...

Do I need to set these configurations in my BIOS? As you linked it.

When I turn on HiSpeed in BIOS, I get this kernel panic:

If you want UB2.0 speed, you must set USB2.0 controller mode to HiSpeed. Goes without saying and this affects all OS you'd install on that old computer.

You're experiencing a KP because your setup is incorrect.

 

OpenCore is not suited to old Core2Duo platforms given that it does not support generating C states & P States like Clover and earlier bootloaders such as Chameleon/Enoch do. Generating C States and P States is necessary to provide proper CPU Power Management. You should switch to Clover for your old system, Opencore is not really suitable here.

 

I've noticed that you inject XHCI-unsupported kext but that's for USB3.0 which your system does not have; as such, get rid of that kext.

You also inject a SSDT-EC-Desktop patched table but that's not required for El Capitan. I'd get rid of it too.

nVidia GeForce 9600 GT is Tesla and should therefore be natively supported; as such no need for the nVidia WebDrivers nor your boot arg nvda_drv=1. In fact, did you actually install the Web Driver? You may just need to inject a few nVidia properties through DSDT patching or, ideally, dedicated patched SSDT should the card not be supported OOB.

Can you link me a tutorial how to make Clover hackintosh?

I'm afraid that, back in the days of El Capitan 10.11, I was still primarily using Enoch... But you may seek inspiration from my Dell Vostro 200 guide; it's an old Wolfdale Core2Duo but the process is good and there's a good chance most of the Clover setup provided in my High Sierra guide will work. Don't re-use the patched DSDT of course, it's not suitable for your Asus computer. Some of the kexts won't be applicable either (Intel82566MM LAN kext for instance).

 

Note that you may consider replacing that old Conroe CPU of yours by a younger FSB1333 Wolfdale C2D or C2Q CPU with SSE4.1 instructions set and that would allow you to get you up to macOS Monterey. Your nVidia GeForce 9600 GT will be natively supported up to High Sierra 10.13; beyond that, it requires special patching to run it in OpenGL-mode only since it has no support for Metal.

I tried looking in this guide and I didn't understand. Can you make a guide how to make Clover Hackintosh on Intel Core 2 Duo E6850? That would be really helpful! Unfortunately, I don't have money to afford new CPU.

The guide I referred you to is a step-by-step guide. If you didn't understand it, I'm afraid I wouldn't be able to help you further.

 

Please note that the CPU model is of no influence to the installation process, it's only a limiting factor with regards to the version of OS X/macOS you're able to install and run.

Alright, thanks.
