After Sonoma 14.4 update USB hub not working on MacBook

I was able to fix this! My usb hub stopped working after Sonoma upgrade so based on other comments, I unplugged my hub, restarted the Mac, then plugged the hub back in. Like a miracle, my usb hub and all items were now recognized. Please give that a try. Good luck.

Not only will my Mac no longer recognise peripherals, it also won't accept power via any of the adapters I have tried. I now have to choose between getting charge and, just for examples, backing up, having a monitor, or connecting to ethernet. This simply has to be the worst update to any system that I have ever experienced!

Good grief ! I didn't have a problem before with 14.1 but now after installing 14.4.1, my M2 MacBook Air no longer recognises my keyboard attached to the hub on a Dell U3219Q display connected by USB-C, even after multiple reboots. I didn't have a problem with 14.4 so instead of fixing the problem, 14.4.1 seems to have created the problem for me !

[Update - so looks like the problem has to do with the "allow accessories to connect" setting. I had to change the setting to "Ask Every time" so that the next time I connected the monitor, I had to give it permission for it to connect. After that I changed the setting back to "Ask for new accessories" and it continues to work even after unplugging the monitor and plugging it back.

I have one bluetooth and one USB keyboard so it's possible that immediately after upgrading to 14.4.1 I had answered "no" to allowing the USB keyboard to connect. Alternatively, Sonoma 14.4/14.4.1 has trouble keeping track of devices that have been connected through a hub and forgot that I had already approved the keyboard before the upgrade. ]

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.

I was having the same issue after upgrading to 14.5. No usb-c hub device was even recognized. I also did not see "Allow accessories to connect" option. What I discovered was when I opened parallels Desktop and had a windows VM running and I plugged the USB-C Hub in. I would then get the option to use the hub on my mac or windows. I choose mac and it works fine. Hoping they will fix this in 15 but for now I have a work around. Hope this helps.

That's M CPU chips only.

Allow accessories to connect to Mac - Apple Support

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 problem on my brand new iMac with M3 chip and the Allow Access... option is present ONLY on laptop Macs 😡

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.
