How do I fix the ‘USB Accessories Disabled’ message on my Mac?

When you see an alert that says “USB Accessories Disabled. Unplug the accessory using too much power to re-enable USB devices,” what’s happened is your Mac has temporarily shut down that port. It feels the connected device or cable is drawing more power than the port can safely provide.

Your iPhone may still be charging if it’s connected, but the Mac won’t properly “see” it. And Finder won’t recognise the iPhone, so Dispute Buddy can’t run.

How to fix it

1. Disconnect your iPhone cable from both the Mac and the iPhone. Wait 10 seconds, then re-connect it firmly

2. Connect your Mac to power

3. Use an Apple cable, not a cheap one

4. Try a different port

5. Remove any USB hubs, docks, adapters, or extensions. Plug the iPhone directly into a port on the Mac.

6. Disconnect other USB devices, external drives, webcams, any other phones

7. Restart your Mac, then restart your iPhone. Temporary power glitches often clear after a reboot.

8. Inspect and clean the ports. Check the cable ends and the iPhone/Mac ports for dust, debris, or bent pins. Gently remove lint with a soft, dry brush.

9. Check your Mac and iPhone for software updates.
