USB Devices Not Connecting on macOS Sonoma 14

Users say their USB devices are not connecting to their Macs after installing macOS Sonoma 14. It’s a surprisingly widespread issue for this software update. But before sending in your devices for hardware repairs, I suggest going through these troubleshooting steps—they fixed this glitch for many affected users.

How macOS Sonoma 14 Is Causing USB Hub Issues

The latest macOS update could cause USB ports to malfunction. Various USB devices, e.g., keyboards, hard drives, headphones, and wireless peripherals, are not connecting to macOS Sonoma 14. What’s worse is that the issue goes beyond Apple devices. Users report that their third-party monitors’ ports also stop working if connected to a macOS Sonoma 14 MacBook or iMac.

How To Connect USB Devices on macOS Sonoma 14

Try restarting your affected Mac and monitor a few times. But if your USB devices still don’t work, proceed with the below troubleshooting steps:

1. Allow Accessories To Connect in Settings

Time needed: 5 minutes

It seems these USB connectivity issues stem from a glitching security protocol. It supposedly prevents unauthorized USB hub access. Although this feature could potentially boost your overall security, consider turning it off until Apple presents a better solution. Here’s how to allow USB accessories to connect to your Mac:

  1. Click the Apple menu icon > System Settings.

2. Try Using Another Monitor or USB Hub

Connect your iMac or MacBook to another monitor or USB hub—see if the problem persists. You could even repeat the above troubleshooting step. Some users claim that the connectivity issues with their USB ports and hubs will just disappear on their own.

3. Factory Reset Your Mac

As a last-ditch resort, you can consider factory resetting your Mac. It should revert whatever hidden function is causing your USB ports to malfunction. Just note that you’ll have to log in to your Apple ID and iCloud accounts again afterward.

  1. Click the Apple menu icon > System Settings > General > Transfer or Reset.
