It seems does't support arm Mac

I try it on MacBook Air m1, but it looks that the code does't support arm deviceExecuting: /usr/bin/kmutil install --volume-root / --check-rebuild
Not rebuilding KC for arch: 'arm64e'
kmutil done
Executing: /usr/bin/kmutil load -b es.govost.ryan.Thunderbolt3Unblocker
Incompatible architecture: Binary is for x86_64, but needed arch arm64e

I don't know if it is possible to support the M1 Macs. Do they support third-party kernel extensions? Apple has been moving to eliminate them for several releases now.

[251305060]

If third party extensions is blocked, is it have other possibility to unblock tb3. such as add md5 string of 11.0.1 to TB3 enabler

Other methods of unblocking involve patching the kernel extensions on disk. I don't know if those methods still work. They might, but Apple is continuously adding more protections to the system. You should probably look into getting a supported dock.

I cloned the project and try to compile it in universal mode (support both arm and intel) and it seems that some asm instructions not working, see attached screenshot.

Ah yeah. It does need to be updated for ARM. I do not have an M1 Mac so I am unsure what changes need to be made.

Mine is on the way...It seems that the asm mov cr0 or cr3 is only available in Intel. I'm not sure if this instruction could be translated by Rosetta

[rgov]

Kernel extensions would not be able to run under Rosetta. (I am still not sure this can be loaded at all.)

Basically the whole xnu_override.c would need to be re-implemented for ARM.

It seems that would be quite a lot of working... How can I test if the kext can be loaded in M1?

HP ZBook ThunderBolt Dock can directily use under M1 MacBook Air without applying this kernel patch, So if you have a M1 chip Mac, you can try plug the dock without patching this driver.

Really? It's a good news. I just got my M1 Air but haven't got a chance to test. I'll have a test and then post updates here.

I‘ve just tested when I got my M1 Air, and I asked a seller who have this dock on sell. He confirmed that the dock is perfectly supported. All interfaces are perfectly worked. And displayPort can output 4k@60Hz after the dock updated the latest firmware.

Hi, I'm also in this situation. I have MacBook Pro M1, and if you doesn't mind, I would like to test. Could someone share me the fixed code or binary?

Macs with M1 chip support HP ZBook ThunderBolt Dock natively, and no need for any kernel patch.

Ok, but I already have Dell TB16 dock using with my Dell laptop. It would be fine if I can us the same dock for both.

TB16 Dock has problems in PD charging. So the problem may not related to the driver or that saying "apple's blocking".

Do you mean this dock? https://support.hp.com/gb-en/document/c04959218
Interesting...Intel Macs doesn't support this dock yet and patching is must.

Yes, surely this one. Intel Macs can't support this but M1 Macs can use this without any patching.

[baronmax]

Yes I tried the HP ZBook / Elitebook TB3 dock with Macbook M1 and it seemed to work without any patch despite showing as 'unsupported'. I tested the USB connection only as I only have one TB3 cable at present.

HP ZBook 150W Thunderbolt 3 Dock this dock is no longer for sale.
So no testing with thunderbolt unlock?

I think that I found out what we need to do to get this running on ARM Macs. According to the Apple Support doc it is possible to run kernel extensions, but not recommended for security purposes.

Once you lower your firmware security level in RecoveryOS, compile the project with Xcode. I haven't taken a look at the xcode project yet, as I have just discovered this awesome repo and wanted to look into the possibility first.

[rgov]

There is a source file that is highly specific to Intel processors that has no hope of working on ARM without a developer porting it. Simply using Xcode is not sufficient.

YES ,It work on M1 MBP macOS 11.2.3,but when I unplug my External hard disk from this HP TB3 dock , my MBP Crash and reboot. Are you having this problem?
