After updating to Tahoe, USB devices connected via USB hub are no longer recognized

After the 26.0.1 update the audio through my Thunderbolt dock because unusable... full of pops and drop-outs.

At that point I shut the computer down and unplugged the dock from power, then plugged it back in and restarted the Mac.

This seems to have resolved everything; audio is OK now, and my iPhone mounts (which would not before).

As the title says, after updating my Macbook Pro to Tahoe neither my external mouse or keyboard are being recognized. They are both connected via a port hub that is also used to connect the external monitors, which work fine.

You do not say what specific " port hub" this is ...(?)

Did you search the developers website or contact their: Support/Help/FAQ/Known issues/compatibility/updates…

a possible firmware update may be available for comparability..?

Otherwise shutting down and restarting with your device plugged in and compare your results.

>Shut Down...

if no resolve—

To be proactive you can file a bug report / submit your Apple Feedback here: Product Feedback - Apple

Sorry, it's an MCY Docking Station that I bought from Amazon back in 2021. There's not much in the way of a product support page for it or anything in the line of firmware updates. However, it's worked fine without any specific tweaking up to this point. I've also restarted it with the hub plugin and my USB devices still were not working.

see if this is it...

I think I’m running into the same problem. I have an anker thunderbolt 3 dock that connects 2 monitors and all my usb peripherals.

Since upgrading to Tahoe, my MacBook will sometimes just not connect to any of the peripherals. The laptop will chime and I can see that it’s charging, but monitors don’t connect and I’m unable to use my keyboard.

I’ve noticed this on 2 MacBook Pros (an M1 Max and an M2 Max). Neither had this particular problem before upgrading to Tahoe.

I’ve found rebooting the laptop can get things working again, but interestingly if I switch to a different thunderbolt port, everything will connect without issue. (Unplugging/plugging into the original “problem” port does not resolve the issue)

Hoping this gets resolved in an update. Needing to move ports around every time I start my day is going to become annoying.

I hope everybody is reporting this: Feedback - macOS - Apple

I'm having a similar problem with an OWC Thunderbolt dock, although it only afflicts my iPhone. Since the Tahoe update, my phone is not mounted by Finder (although it does charge) and is not accessible by Image Capture or Xcode. Yet a thumbdrive plugged into the dock mounts just fine.

Plugging the phone into the computer with the same cable causes it to mount, so it's not the cable.

I do experience the same issue. I have a MacBook Pro M4 and after I updated to MacOS 26 my monitor and webcam which are connect via Satechi Thunderbolt 4 Dock Slim Hub Pro are not being recognized anymore.

When I plug the monitor into my MacBook directly it works however I use my Mac in clamshell mode so my whole setup is messed up now.

I just updated to MacOS 26.0.1 but the problem still persists.

Having a very similar issue right now. Just updated to Tahoe 26, and my Baseus multi-port usb-c dock which was working absolutely fine just stopped being detected post update, immediately. Non-existent in the system report.

Every single peripheral is connected to that dock, now im currently on hdmi to a monitor and connecting my keyboard directly to my Mac mini to type this.

Mac mini 2024 , M4 Pro.

Any fixes yet?

Same here with Nedis USB-C 7 port hub, working fine on Sonoma, but after update to Tahoe no longer working. Tried every obvious solution (reboot- disconnect hub - reconnect etc). Usb-C hub is visible in system properties and also usb-drives connected to hub are visible there. However in finder they are not showing as external drive (the setting to show external drives in finder is ticked). apple device is iMac M1. update to MacOS 26.0.1 did not solve the issue.

Have a CalDigit Thunderbolt 4 Element with ext. Drives for back up connected to a MacMiniM1. Since Tahoe after automatic backup + unmount + PowerOff the drives AND then PowerOn the next day the drives are not recognized. Not in Diskmananager etc.

After restarting the Mac the drives appear. Backups etc. run fine.

back-up ends+unmount+poweroff I cannot get access back until restart…

sounds like the same sort of issue mentioned here

br -T.

had the same with M4 pro after upgrade to 26.0.1. After trying every combination of reboots, power and connection went to 40cm cable solution. worked! Very annoying.

Same issue for me after updating to Tahoe. Using Amazon Basics Thunderbolt 4 dock.
