Dell TB16 dock features do not work on MacBook Pro 13" 2018 (July release) + High Sierra 10.13.6 #21

cmericli · 2018-07-25T18:33:54Z

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" }
KernelCache ID: F9BC99216674C6596DDC59DC7943CB58
Kext with invalid signatured (-67050) allowed: <OSKext 0x7fd9a71768a0 [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,
Cetin

Same problem here; 2017 15" MBP, Dell TB16.

rgov · 2018-07-25T23:41:00Z

The log you posted does not show an error, it looks like it loads successfully.

There are a few other reports of video not working with the Dell TB16. However, this is not something that Thunderbolt 3 Unblocker addresses; as far as this project is concerned, it is activating the dock, but other parts of macOS are responsible for the video output.

If you find a solution please feel free to share the knowledge here, but I’m afraid that it is outside the scope of this project, and as I don’t have access to one of these docks, I cannot investigate what Apple changed to break the video out.

cmericli · 2018-07-26T00:59:02Z

Ok understood. So is it normal for it to not detect the dock when I use "crutils enable --without kext" but recognize when I use "crutils disable"? That was one difference between installation instructions here and KhaosT's.

I will definitely post here if I can find any solutions.

Many thanks for putting this together!

rgov · 2018-07-26T03:40:41Z

The csrutil issue isn’t quite normal but I don’t have enough information. The kext seemed to load. Did you remember to plug the TB16 in after you loaded the kext?

cmericli · 2018-07-26T03:45:51Z

I sure did. In fact, multiple times.

rgov · 2018-07-27T00:02:38Z

@cmericli Can you turn SIP all the way on (csrutil enable) and then run nvram csr-active-config and tell me what the output is? I guess it's possible that the T2 machines have an extra SIP bit, but I'm not aware of it.

Edit: Someone told me that csr-active-config does not exist if SIP is enabled, so this isn't needed anymore.

rgov · 2018-07-27T04:24:36Z

Ok how's this. Please do csrutil enable --kext. Immediately after loading the kext, please run sudo dmesg and attach the output.

cmericli · 2018-07-28T17:04:48Z

when is "immediately after loading the kext"? right after I run csrutil or after I reboot and login?

rgov · 2018-07-29T01:40:30Z

If you've installed the kext into /Library/Extensions or wherever, move it out (like to your Desktop).

Reboot into the recovery partition and run csrutil enable --without kext then reboot back into regular macOS.

In the Terminal, run sudo chown -R root ~/Desktop/Thunderbolt3Unblocker.kext && sudo kextload ~/Desktop/Thunderbolt3Unblocker.kext && sudo dmesg and put the output here.

rgov · 2018-07-31T04:22:59Z

So it looks like it is succeeding with SIP disabled with csrutil enable --without kext. And in your system profile (About This Mac → System Report... → Hardware → Thunderbolt) the TB16 shows up with "(Unsupported)" still, after unplugging and plugging it back in?

cmericli · 2018-07-31T04:23:51Z

TB16 is in the office. Will check first thing the morning and report back.

cmericli · 2018-07-31T20:17:43Z

It now does detect the Dell dock but nothing on the dock works.

rgov · 2018-08-01T01:53:37Z

Ok thanks! It looks like Thunderbolt3Unblocker is working then; after it "unblocks" the dock, it's up to macOS and other drivers to support its features.

When you say "nothing on the dock works," you are talking about USB ports, etc.? Note that an OS release a few months ago stopped the video output from working, but other features are expected to work.

cmericli · 2018-08-01T01:59:43Z

Yes, the Thunderbolt3Unblocker is doing its part like a champ :)

You are right. I did not check anything other than the video output previously but now I did and USB etc. features do work. The problem is video and it seems like an OS X issue as you said.

Many many thanks!! :)

rgov · 2018-10-01T15:48:42Z

Hey @cmericli, check out a new driver for the TB16 that may re-enable video output. https://support.displaylink.com/forums/287786-displaylink-feature-suggestions/suggestions/33252664-macos-high-sierra-10-13-4 Let me know if it fixes the issue for you.

yajin · 2018-10-04T06:35:18Z

same error here. The dock is recognized by the system, but the video output does not work.

Tried the displaylink driver v4.3.x, it does not work either.

ps: my system is 10.13.6.

Anyone success with the tb16, please share your experience.

cmericli · 2018-10-05T00:33:33Z

Hi Ryan,

Thanks for the heads up. I don't have the TB16 with me at the moment but will try as soon as possible and report back.

Best,
Cetin

forroden23 · 2018-10-18T18:59:16Z

hi I have the problem when the dock is not even recognize, tried this sudo chown -R root ~/Desktop/Thunderbolt3Unblocker.kext && sudo kextload ~/Desktop/Thunderbolt3Unblocker.kext && sudo dmesg and put the output here.
but getting /Thunderbolt3Unblocker.kext failed to load - (libkern/kext) authentication failure (file ownership/permissions); check the system/kernel logs for errors or try kextutil(8).
I checked the sudo pwd and is correct.

rgov · 2018-10-18T19:34:20Z

Try root:wheel instead of just root.

forroden23 · 2018-10-19T14:54:20Z

ok I got it to show, but it says unsuported, but need to plug it disconnected from power source and then connect the power source, If I connect it with power sources is not been detected, weird, is someone else having the same scenario?

orappold · 2018-11-28T12:20:15Z

Guys, do I understand correctly that the TB16 dock does not provide video passthrough for MBP's? That is the use case for having a dock to enable multiple displays?

Does this affect other TB docks as well? It hard for me to understand the reasons behind...

t3b4n · 2018-11-28T12:45:36Z

The reason is the TB controller on TB16 isn’t certified by Apple, that’s why the tb3unblocker is needed, but as a third party solution, you can’t have the guarantee that it’ll work in all the devices available. I surrendered on the TB16 because of all of its problems and went to the Dell WD15. It’s not thunderbolt, it’s usb, but at least it works and as of now I have zero complains on the dock.

Gosh, this is lame. I have Dell for work with the TB16 and I was hoping to have an easy way to just dock my new MBA 2018. The unblocker works so far - everything except Video works.

I was hoping that the displaylink driver above will solve it but it didn't for me...

I also have a D3100 at home which is UBS3.0. Unfortunately I need to use a bridged usb-c hub to connect to that. Weird stuff is that it recognizes both displays with a black screen and nothing more. I can mouse the move within the screens but nothing more...

If you see black screens with the mouse cursor you need to upgrade to latest Mojave version, it looks like 10.14.0 version does not work but current 10.14.3 works for me.

Hi feneclabs, what MacBook do you have ? How is the doc working so far with the latest Mojave version ? Everything port working ? Any issues?
thanks

I have a MB Pro 15" 2018 with touch bar.
TB16 is still not working, but I have a D6000 that works "ok", I managed to get 3 screens but one day one went black. I used a VGA adapter to get my 3rd screen working again.

Overall I'd say that mutli-screen on MB is a total failure riddled with workarounds, random support and expensive adapters compared to Windows/Linux where everything just works.

nietsze · 2019-06-27T09:05:26Z

MacBook Pro running Mojave 10.14.5 (18F203) doesn't work with TB16. It's supported out of the box (without TB3 enabler hack), however apart from power feed, nothing seems to work. Install of https://www.displaylink.com/downloads/file?id=1257 didn't help neither.

Pyroseza · 2020-08-28T20:00:16Z

What's the latest on this, I just got a refurbished TB16 dock today and I have a MBP 18 15" currently running Catalina. I tried the unblocker but no luck with video output either. Has anyone figured this out?

micahqcade · 2020-08-28T21:27:10Z

The dock has to be updated to 1.02, you need DELL to do this. I have a '19 MBP15 and it works.

Pyroseza · 2020-08-28T23:01:18Z

@micahqcade thanks for the reply, so essentially a firmware upgrade?

How can I achieve this from the mac?
