After Sonoma 14.4 update USB hub not working on MacBook

Phew!! Upgraded to 14.4 after reading all this. I suspect that because both my docks are Thunderbolt, I made out okay. I'm using a U3224KB Dell Monitor with a built in Thunderbolt dock and I have a OWC 96W Thunderbolt Dock going to the Thunderbolt through port and it is working as is my iLok dongle with Pace copy protection that is also reported to be an issue. Hope this helps.

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.

I tried one of the hard drives on my 2023 MacBook Air 14.2.1 and plugged directly into the computer it did not show up. Plugged it into a USB Hub and it did show up. So too k the usb hub and hooked that up to the MacBook Pro and the hub showed up. I have the settings set to ask to add any external device right now. But plugging the same hard drive into the usb hub and nothing. Reboot and nothing. This is insane. I need the hard drives to be connected to my MacBook Pro some how. So I took the only Apple thunderbolt cable I have and plugged the hard drive into that and it showed up right away. Are USB-C cables no longer compatible? Really?

It absolutely did not. I have a MacBook Air M2 with the Apple USB-C AV Hub (USB-A, HDMI, USB-C) and my monitor randomly is not recognized and cuts out. It fixes itself in a matter of about 5 seconds. But super annoying regardless.

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!

It is the worst update ever. It destroyed my entire flow.

I must undock my Macbook and ping-pong between stopping the monitor, connecting, and reconnecting the cables.

It is a nightmare. Before the update, I had to plug my setup into a Macbook using one cable, and that's it.

Please fix this!

Same issue here - running two Dell monitors and also have a KVM...

The Mac won't recognize the external monitors through the KVM now....

Love my MAC but this has to be fixed - 3 windows comps hooked up and they are working fine. Even after the USB hub update the monitors still can't be seen. Using an Iogear 1944 KVM connected to pluggable usb hub to turn the thunderbolt connect to 2xdisplay port outputs....worked fine for years until the last update that broke everything

This is a f**ing nightmare.

Since the upgrade, my usb-c hub still works when connected to the M2 macbook Air.

The power goes in, the additional screen works fine via HDMI.

BUT... the Apple USB2 keyboard is not recognized anymore. So I've tried connecting it via an Apple USB-C <=> USB2 adapter and even there it doesn't work!!

I've tried all the suggestions and... it worked, twice! For example yesterday, miracle, things worked. And this morning, not anymore. I don't manage to find out what changed, but today I tried many different procedures again and it won't recognize the keyboard anymore.

This is so annoying that an upgrade creates such issues.

Apple, post a fix NOW!!!

I have a similar problem with USB audio interfaces. Regardless of the hub, regardless of the interface, all drivers up to date. Random and unexplained drop out, interface needs replugging / restarting. Critical issue in the middle of a live concert! 14.4.1 did not correct problem. (M2 Max, 32GB, 14.4.1).

My MacBook Air M2 is also not able to provide two extra monitors. I now have them both working again, but only in mirror mode. So the screen isn't split. Is the only solution getting an expensive docking station or are there any other options?

Tim,

Thank you for the information and actually talking the "hit" on this problem. I had issues with 4.4 & 14.4.1 with two hums on a MacBook Pro M1 and have been holding off on the latest update. If Apple would incorporate a roll-back solution I'd go to 14.5 today and hope I don't have any issues. Now 15.0 is looking like the next upgrade here. I'm not about to fix something that's not broken. :-(

I have the same issue with two dell monitors, on reddit there's also people complaining of the same with samsung monitors. I also have an M2 Max.
