The recent macOS Sonoma 14.4 update, eagerly awaited by many due to its new features and numerous security updates, seems to have a side effect: a malfunction in the functionality of USB hubs and displays with integrated USB hubs, as well as other peripherals such as mice and keyboards. But there is a solution.
macOS 14.4: a temporary solution to USB errors
Some users report that, after updating to macOS Sonoma 14.4, their connected USB devices don't work exactly as they should. This includes USB hubs, like the highly recommended UGREEN Revodok Pro 210, the smaller Revodok USB C Hub, or the Belkin USB-C Hub, as well as simpler devices like keyboards and mice.
Fortunately, while Apple works on an official fix, there's a temporary adjustment that has proven effective for many. The steps to follow are:
- Disconnect all USB devices from the Mac.
- Go to System Settings > Privacy & Security > Allow accessories to connect. Here, select the "Always" option.
- After changing this setting, restart the Mac for the changes to take effect.
- Once the Mac has restarted, reconnect the USB devices. A confirmation notice should appear, after which the devices should begin to work again.
In other cases, some users recommend toggling between "Always" and "Ask every time" in step 2, especially after disconnecting and reconnecting USB devices.
Remember, this is a temporary solution that, although successful for several users, may not work for everyone. In any case, while we wait for Apple to release a definitive update, we can continue to enjoy the rest of the macOS Sonoma 14.4 updates.
