Enable unsupported Thunderbolt 3 peripherals on macOS

⚠️ Thunderbolt 3 Unblocker does not yet work on Apple Silicon.

Thunderbolt 3 Unblocker

This project provides a kernel extension that unblocks unsupported Thunderbolt 3 peripherals (such as the Razer Core) on macOS.

This accomplishes the same goal as KhaosT's TB3 Enabler, which works by patching IOThunderboltFamily on disk. This kernel extension performs the patch in memory and on-the-fly.

Note there is likely a reason why IOThunderboltFamily considers a peripheral unsupported in the first place. Use at your own peril.

This kernel extension has been tested against macOS Monterey 12 and as far back as macOS Sierra 10.12.6. Please check for open issues before using on other versions, and review the troubleshooting guide.

Installation

Please head over to the Releases page for binaries and installation instructions.

Building

To prepare your development environment, please run

git submodule update --init --recursive
brew install cmake

Build the project with Xcode. Make sure to change code signing settings as appropriate.

Load the kernel extension with:

sudo chown -R root:wheel Thunderbolt3Unblocker.kext
sudo kextload Thunderbolt3Unblocker.kext

If loading the kext fails: Reboot into Recovery Mode and disable kext security restrictions using csrutil enable --without kext.

If you are developing the kext, you should know that the NVRAM variable t3u-incompatible is written whenever there is a panic while loading the kext. The presence of this variable prevents the kext from loading again on the same system version. You may want to disable the code that does this (in Thunderbolt3Unblocker.c), or delete it with nvram -d t3u-incompatible.

xnu_override

This project also implements a simple, reusable in-memory kernel patching library. The author has released it under a permissive license in the hopes that it will be useful.

thunderbolt3unblocker's Issues

Would like to know if it works on 10.13.5

Would like to know if this patch works on 10.13.5
Thanks!

It doesn't seem to work for me

Hi!

I followed all the instructions and my Dell dock still doesn't work.

Here is the output of sudo kextcache -i /:

I have installed this https://github.com/KhaosT/tb3-enabler before and it worked without any problems but it doesn't seem to be working for OSX 10.13.4 so I tried this one but it doesn't work either.

Can anyone help me?

Thanks!

Mouse become laggy every 5 seconds

I'm using a HP TB3 Dock, and I installed the amazing TB3Unblocker. But it seems that the mouse (the Trackpad, too) laggy for about 500ms every around 5 seconds. I don't know if this is a problem of the TB3Unblocker itself, but the system become fine after I uninstalled, of course, the dock become "unsupported" again.

reboot MacBook and TB3 dock not support until re-plugin cable

my environment:
MacBook Pro 15, 2018
macOS Mojave 10.14.1 (18B75)
dock: "HP Elite Zbook Thunderbolt 3 Dock"

it works well after your solution, thanks! only 1 issue, it will not work when restart MacBook, until I unplug and plug the thunderbolt3 cable again.
Is it a known issue? how to fix it ? thanks.

DisplayPort is not work！Is there any way to do it

universal audio Apollo 8chan

t3u-diagnose.txt

Hi There,
I am trying to use this kext to enable thunderbolt on my Mac Pro 5. 1 to use with a Universal Audio Apollo device, any ideas why we might be having trouble.

Any help greatly appreciated,

All the best,

Adam

enable SIP after running the script

After I ran the script listed in the repo, I restart to recovery OS to enable SIP again. Unfortunately, when I go back to macOS again, I can't load the Unblocker kext again. So does the kext need SIP disabled all the time when I want to use the unsupported Thunderbolt 3 peripherals?
My OS is macOS Catalina 10.15.1 and the script below is copied from the release page.
https://github.com/rgov/Thunderbolt3Unblocker/releases

sudo sh -c 'chown -R root:wheel /Library/Extensions/Thunderbolt3Unblocker.kext &&
chmod -R g-w,o-w /Library/Extensions/Thunderbolt3Unblocker.kext &&
kextcache -i / &&
nvram -d t3u-incompatible &&
kextload -b es.govost.ryan.Thunderbolt3Unblocker'

Restarted since the installation of Thunderbolt3Unblocker

My Mac has been restarted since the installation of Thunderbolt3Unblocker, which has happened 7-8 times.
I want to know if it is related to the installation of Thunderbolt3Unblocker.
thanks.

xnu_override: Disable interrupts when patching

There is a chance that an interrupt will happen after we've modified control registers and before we reset them. We should disable interrupts during the small window in which patches are being applied.

macOS Catalina

There has been one unconfirmed report that Thunderbolt 3 Unblocker does not install on macOS 10.15 "Catalina."

If you are having difficulty installing and using Thunderbolt 3 Unblocker on Catalina, please follow the troubleshooting guide and report here whether you are able to get it to work or not.

Update: Users have reported success using Thunderbolt 3 Unblocker on macOS 10.15 beta 8.

Does not survive a reboot

Applied file and commands, unplugged and plugged Akitio Thunder3 Quad enclosure, worked great. Rebooted, back to square one. Applied commands, unplugged and plugged, worked great.

Is this expected behavior?

Dell TB16 dock features do not work on MacBook Pro 13" 2018 (July release) + High Sierra 10.13.6

Hi,

Trying to get a one-dock-to-rule-them-all solution for my Dell laptop and new MacBook Pro. Followed your installation instructions but I'm getting the following output, and no device is recognized in the system information

Kext with invalid signatured (-67050) allowed: <OSKext 0x7fec5b88dec0 [0x7fff8ec98af0]> { URL = "Thunderbolt3Unblocker.kext/ -- file:///Library/Extensions/", ID = "es.govost.ryan.Thunderbolt3Unblocker" }

I ran crutils enable --without kext. When I do crutils disable, the dock is recognized but still no video output.

Let me know if I can generate more data to chase this issue

Best,

10.13.5 does not appear to work

Tried to use with 10.13.5 which was released recently and it does not appear to work on it. Might need an update for compatibility.

Revisit automatic testing on Travis CI

Currently, Travis CI only tests that the project builds. However, we cannot load the kernel extension due to System Integrity Protection and kext user consent.

• travis-ci/travis-ci#5819
• travis-ci/travis-ci#9377

Kernel extension fails to load, missing vm_protect and get_task_map

With macOS 10.13.4 and latest commits on this project I get:

	<key>OSBundleLibraries</key>
	<dict>
		<key>com.apple.iokit.IOThunderboltFamily</key>

	</dict>

For x86_64:
    2 symbols not found in any library kext:
	_get_task_map

Automatically protect an incompatible system

When the kernel extension loads, it performs a self-test to make sure that it can patch, execute, and unpatch a target function before it attempts to modify IOThunderboltFamily. However, if this self-test fails, it still panics the system. This causes problems when you upgrade from a working system to an incompatible one (#23).

What it could do use some kind of persistent storage to record the system version before we start patching, and clear it when patching succeeds. If we see this record on the next boot, we know that we panicked, and can skip patching.

I attempted to implement this using NVRAM for the persistent storage, but it turns out that this is not so straightforward. We need to block loading until IODTNVRAM is available; here's a thread on the topic but it's not clear what I need to change.

🗒 A note on the Dell TB16

Many people file bugs here about their Dell TB16 dock.

The USB, Thunderbolt 3, and audio out ports should regain functionality after installing Thunderbolt 3 Unblocker.

However, video output does not work. Unfortunately, this is out of scope for this project.

Thunderbolt 3 Unblocker allows the Thunderbolt 3 driver to recognize the TB16, but other drivers in the system are responsible for activating the downstream peripherals, including the display. For whatever reason, an update to macOS High Sierra broke support for the displays attached to the TB16.

Update

You could try performing a firmware upgrade on the TB16, which has been reported to restore video (HDMI output). However, the firmware upgrade must be performed from Windows. It is unlikely that this will work from WINE or a virtual machine.

Thank you so much

Doesn't seem to work on 10.13.4 (High Sierra)

Same as previous project: this doesn't seem to work under 10.13.4

Mojave users can try tb3-enabler

see: https://github.com/KhaosT/tb3-enabler
should be working.

DELL TB16 is not detected. Two monitors work as mirrored.

I've tried to upgrade TB16 from dell Latitude 7300 with thunderbolt but got an error "reading asmedia usb 3.0 host controller firmware failed".
After that I've upgraded it from Ubuntu using FWUPD to firmware version 3.12.002.
Now I got two monitors worked as mirrors and plus my laptop monitor on MacOS Mojave 10.14.6 . But on Ubuntu or Windows they extend my desktop correctly and I got three separated monitors.

---

Unlocker is loaded

But there are no devices connected.

I attached t3u-diagnose.txt

t3u-diagnose.txt

Built successful but I can not find the created kext...

Latest version doesn't work for keyboard and display

I uninstalled the kext before updating to Mojave. After the update, I downloaded the new version and installed it. The device is recognized and appears as active in the system report, my mouse and iPhone work over USB, but my keyboard and display port display don't.

Device: Dell TB16 thunderbolt dock.
Computer: Macbook pro 15 inch with touch bar 2016

Not enabling device

I have a Dell TB16 dock that was previously working using the TB3-Enabler patch, I updated to 10.13.4 this morning and was unable to get it to work using that patch so I tried this one, I have the kext loaded but the dock still isn't working for me. What is a good first troubleshooting step?

Doesn't seem to work on 10.14.3

I follow the installation on https://github.com/rgov/Thunderbolt3Unblocker/releases but it still does not work and still says unsupported

this is the output i got in terminal:

Crashes on macOS Mojave beta

Hey, It seems to crash on Mojave every time it is installed.

Kext fails to load, missing _memcpy_chk in kernel

Thank you for the project.
I have some difficulties in building the project,

i have done (csrutil enable --without kext.), and when i run the project, fail comes up.

and try to put this in, but i dunno am i doing wrong,
git submodule update --init --recursive
brew install cmake

i am very new to xcode and programming, so if i haven't done sth very minor, please tell me step by step, thank you very much.

Hope to increase support for 10.14.1

Hope to increase support for 10.14.1
thanks!

Can Support Mojave 10.4.5?

Today Apple Release the Mojave 10.4.5
Had anyone tries to update 10.4.5 and the Thunderbolt3Unblocker still working?

Doesn't work for 10.14.4

No video from Dell TB16 dock

Thank you for your efforts! I have built and loaded the kext. It now sees my Dell TB16 dock. Ethernet, audio and all USB ports are working fine. However, no video at all from the dock, from any of the ports. (HDMI, Displayport, and MiniDisplayport). Please advise?

Mojave 10.14.6 Beta (18G29g)

my system updated to 10.14.6 Beta (18G29g) and the TB16 Dell dock does not work any more.
I have disabled the kext security restrictions and reloaded the kernel patch there was no error on the terminal. but only the dell cable is recognised.

Can you please tell me how to collect more log form kernel loading to give more debug.

Thunderbolt3 Suddenly disconnected

Can't build xcode project

Hi, i don't know what I'm doing wrong, but I can't build with xcode.
I got this error:

Extension is not automatically loaded after reboot

Kernel extension have to be reloaded every time after reboot, have tried move it into systems/library/extensions, doesn't work.
I am not very familiar with this technique, any chance to make this kernel extension load automatically after reboot?
Many thanks!

Could work on MacOS Catalina(10.15 Beta 19A471t) But Installaion need to be done under mojave.

Just a report. I have clean installed Beta Catalina, and after that, the installation guide works fine(kext allowed) but tb3 not detected. Works fine but freshly installing not

Dell TB15 partially working

Thanks @rgov for sharing this project.

I am the unfortunate owner of the TB15 dock. Works well on a Dell laptop after some updates to both Windows and the TB15 firmware.
However it wouldn't work initially on a MacBook Pro with OSX 10.14. It would charge, but no devices worked.

After using Thunderbolt3Unblocker, the Power Delivery, USB and Ethernet ports work, but DisplayPort/HDMI outputs do not.

Here's the spew from System Report. The indentations didn't carry over, but it looks to be nested from Bus -> Cable -> Dock.

run `csrutil enable --without kext`

When executing csrutil enable --without kext I get

$ csrutil enable --without kext
csrutil: requesting an unsupported configuration. This is likely to break in the future and leave your machine in an unknown state.
csrutil: failed to modify system integrity configuration. This tool needs to be executed from the Recovery OS.

So shall I need to boot from a Recovery OS? If so, is it ok to do like

https://support.apple.com/en-us/HT204904 covers normal recovery
hold Command+r+s to boot into Single User Recovery Mode.

Thank you!

when building in xcode i got error

does anyone know how to fix it ?
im using 10.14.6
xcode 10.3

thanks

WD15

Guys, sorry it's not a bug or issue. O maybe is. I haven't installed this packaged and I'm asking if should I do it. I kinda need some information first.

I have a WD15 attached to my MB2018 on Mojave. It works perfectly most of the time. mDP works fine, Ethernet works fine, even the battery charge works fine.

However, after some time, it starts throwing SSL erros on the ethernet port. I gotta to reboot it to make it work again. Also, sometimes it drains my battery life so fast (or stops providing power), resulting in a 4%~ battery percentage quickly.

I have to reboot it several times to get it working.

Would this package solve this issues or should I perform a firmware update?

Thanks!
