After Sonoma 14.4 update USB hub not working on MacBook

Macbook Pro M2, monitor Dell ultrasharp 34. I tried everything, from factory resetting the monitor to reinstalling OS. Nothing worked UNTIL I unplugged the monitor, not just shutting it down, and then plugged it in again. Voila, USB-hub in the monitor up and running again.

That's M CPU chips only.

Allow accessories to connect to Mac - Apple Support

I retested my issues after updating to 14.4.1. Unfortunately, this update did nothing to resolve them.

I experienced the same issue on my 2019 Intel MacBook Pro. After updating to Sonoma 14.4.1, my monitors stopped working, the charger wasn't recognized, and the battery was draining rapidly. I solved the problem by resetting the SMC: link to Apple Support.

I'm encountering a similar issue and have tried troubleshooting it with two Mac models:

• MacBook Pro 14-inch, 2023, Apple M2 Pro and 32 GB RAM, running Sonoma 14.4.
• MacBook Pro 16-inch, 2023, Apple M2 Pro and 32 GB RAM, running Sonoma 14.4.

I'm utilizing a Dell P2720DC monitor, which typically functions flawlessly when connected to the Mac via USB-C Thunderbolt. However, ever since updating to Sonoma 14.4, the USB-HUB on the monitor appears to have ceased functioning properly, that is, no USB device connected works anymore.l

I tried the best answers from the community but nothing works for me.

Thank you!!! The answer from FloridaUser2024 helped me. 14.4.1 on Macbook Pro 13".

FIX:

----

1. Unplugged power going into my hub.
2. Unplugged hub from Macbook USB-C port.
3. Restart Macbook. It suggested I'd restarted to fix a problem and offered to re-open applications. I declined.
4. Plugged hub into USB-C port.
5. Connected devices now recognized.
6. Plugged power back into hub, Macbook charging, devices remain connected.

Hope this helps others.

I have the same issue with the new Macbook Air 2024 M3 model. With my old MB Air with an older MacOS everything works perfect. Please fix ASAP Apple

I have a Mac Studio M2 Max. After the update my Huion Display tablet is no longer recognized. We spent a few hours with Huion customer service and could not find solution.

Same issue. That's so frustrating and bring me some productions problems.

After the 14.4.1 update my iMac works as expected!

My Mac mini M1 running Sonoma updated to 14.4.1 did not fix the USB problem. All the fixes that I see talk about settings that are not in my Mini. I have rebooted, power cycled the dock with the USB hub and used every expletive I know and the only way the UB speakers will work is plugged directly into one of the two USB ports on the Mini.

This procedure worked for my Dell U2719D monitor after a Sonoma 14.4.1 update. Thanks for sharing!

I have the same problem. My macbook pro (m2) does not recognize my keyboard connected to the usb hub on my monitor after upgrading to 14.4. I'm pretty sure that nothing is wrong with the keyboard, the monitor or the usb cable because everything is fine with another windows laptop. So please fix this!!!

I have a similar problem. I have MacStudio and after updating to Sonoma 14.4, the hub in Dell u4919dw to which I connected the keyboard, mouse and sound card does not work. Interestingly, when I connect a mouse and keyboard to the rear USB-A ports, it doesn't work either. The sound card connected to the rear USB-A port works properly. If I want to connect a keyboard and mouse, I have to use an external hub connected to the USB-C port. Does anyone have an idea to solve this problem?

Having the same issue, but with the 2020 11” iPad Pro with the USB-C port. After the 17.3 iPadOS update, the iPad will no longer charge. I went as far as buying a genuine Apple charger and cable from the Apple store - no change.

I can connect the iPad Pro to my MacBook Pro M1, which I HAVE NOT updated, and the iPad will charge plugged into the MacBook Pro.

Thanks for the heads up! I will not update to Sonoma 14.4. They definitely broke something!
