Usb C hub not working on MacOS Ventura

This fixed it for me.

Ventura defaults to 'ask for new accessories', but for some reason, it wasn't asking for my hub to connect. Also tried to connect my Apple keyboard directly to my laptop (with a USB to USB C dongle), but still didn't ask to connect. Maybe this was because the Macbook was closed.

Hi,

I'm not sure if that's relevant, but I have the same issue with a keyboard that disconnects over night. It's connected to thunderbolt/usb-c port.

I've found that the name of my keyboard was reported in /private/var/log/wifi.log log as a kind of wifi device. The log shows exact time when the device is being turned off, but does not say what is the reason. So I thought that maybe it has something to do with the thunderbolt network settings? Right now I've deactivated thunderbolt bridge from network settings and I'm going to check if that helps.

What's funny, the "other services" list in the network settings, where thunderbolt bridge was listed, was full of rp2040 entries. That's the chip name my keyboard is based on, but here they are listed as modems.

Maybe your USB hub is also somehow detected as a network modem or such?

I am having the same issue ever since I updated Ventura. My solution every morning is to try to unplug and replug all of the TS4, some times it is not working, and the best solution is to restart my MBP 16 M1.

I believe if you download the Monterey from Apple's website and create the installer on a USB you can downgrade to that.

For the questions, I am using a CalDigit TS4 docking station with its own power. It is not the dock since I get the same problem with the Anker and an off-brand as well.

Update Fixed mine: I removed power (PD passthrough) from the Anker Hub, then disconnected from the Mac, then reconnected the Hub to the Mac, with no Power (PD passthrough) the Mac recognised it, and then reconnected the Apple USB-C Power Adapter to the Anker Hub. All is working again. Tested plugging in and out all good.

I have a non M chip MBP. My problem is that I can see the option of allowing the USB accessoires in the search results in settings, but it is nog present in the settings itself. That is frustrating. Anyone knows a terminal command to change this setting to always?

Hi Jazzy, Thank you for your reply. But with a Non M-chip Mac there is an issue:

I just fixed this issue for my 2021 M1 16" MacBook Pro.

Mac OS Ventura requires you grant access to USB C accessories. I didn't receive a popup prompting me to grant access to my dock, so it didn't work. My steps to fix:

System Settings > Privacy & Security > Allow accessories to connect > Change to "Always"

Choose the security setting you're comfortable with, of course. As soon as I changed this setting, my dock, monitors, external camera, etc came to life.

I don't understand why @apple doesn't fix that with a small update. They released another update for different other things but this was not included. I have tried all of the combinations and nothing worked, I keep restarting my MBP and disconnecting everything with a sequence in order to make it work. Also, Caldigit they suggesting a safe mode to start it but nothing is working. Unbelievable what we are going through.

Yeah I see that now, I hope this fix it for you in future update. But this option seems to have broken a lot of things, for me on M1 even with the setting changed sometimes my external disk is still not showing sometimes it is.

My USB-C hub is connected to my Mac via a USB-C male-to-female extension cord. The problem for me was that my hub was plugged into my extension cord in the "wrong" orientation. I thought USB-C orientation didn't matter, but apparently, it can. Where the hub connects to the extension cord I flipped the orientation and it magically started working. Orientation only seems to matter at the point my hub connects to my extension cord - it doesn't seem to matter at the Mac/Extension Cord connection. It also doesn't seem to matter when connecting my Mac directly to the hub.

I'm not sure if this is related to Ventura or not, but worth a try if you use an extension cord.

Oh my god. I Just installed MacOS Ventura (Macbook Pro 2021 16 MAX) and I have the same issue. My external Display stopped working using USB-C.

USB-C to USB classic works

USB-C to Display doesn't work

That is so disappointing. Can you pleas provide an update on that?!!!

I just updated to Ventura and now my dock isn't being detected. I have a Razer Thunderbolt 4 dock. All of my peripherals work great when plugged directly into my laptop, but don't work via the dock. The cable from the dock still charges though even though my monitors/webcams don't connect through it. Any updates on this?

It worked for me after changing a new configuration in Privacy and Security "Allow accessories to connect". I changed it to "Automatically When Unlocked" and couple of restarts. Hope it helps.

Greeting Dennis

I wish I had not updated to Ventura - on my laptop for work I did not and my Dell WD19S USB-C docking station still works for charging and keyboard / mouse. On my home MacBook Pro it does not anymore and I am really angry about that, because the laptop just came in yesterday and I paid about 3000€ for this thing.

Sure, I could go through the hassle to create a USB stick and possibly downgrade it again, but I am wondering what I paid that insane amount of money for? Apple, fix this! I know it's not easy, but you should be able to afford proper QA and testing phases for your OS. And here I thought Windows was terrible :/...

Just for the record and in the hope of someone from Apple actually reading this: I have 2 M1 laptops (M1 Max and M1 Pro) standing with one still on Monteray and the other now sadly on Ventura.

The WD19S (Dell Docking Station) works fine for mouse, keyboard and LAN on my M1 Max with Monteray. It also worked with the M1 Pro before I updated to Ventura. Now it does not and tbh I am pretty upset :(, because nothing I found online works, safe mode does not change anything either.

Unplugging and re-plugging the WD19S power cord into the docking station makes it appear alive again, but sadly only for about 5-10 seconds. Then it simply appears as if it wasn't attached at all. As mentioned previously, it all works on 12.x.
