Solutions
- Use your device as a self-powered device or connect it to a powered USB or Thunderbolt 3 (USB-C) hub if possible.
Self-powered devices get power from an electrical outlet or their own battery. Bus-powered devices get power from the device they're plugged into, such as your Mac. - Reduce the total amount of power needed from your Mac by reducing the number of bus-powered devices connected to your Mac, or using more of them as self-powered devices.
- If your device is plugged into another device (such as a display or multiport adapter) as part of a chain of devices, the other device might not be providing enough power or passing through enough power from your Mac. Plug your device directly into your Mac instead.
- Make sure the port on your Mac and the cable you're using to connect it to your device both support the same or later USB specification as your device. For example, a device designed to support the USB 3 specification might not get enough power when plugged into a USB 2 port or cable.
- Try a different cable, in case the cable you're using is damaged or defective. If you're using an adapter with your cable, the adapter could also be damaged or defective.
- If your Mac has multiple Thunderbolt 3 ports, connect your device to the Thunderbolt 3 port furthest away from the current port. For example, if your device is connected to the ports on the left-hand side of MacBook Pro, connect to the Thunderbolt 3 ports on the right-hand side.
- If your device has software (such as drivers or firmware) that can be updated, make sure it's using the latest software from the manufacturer. To get firmware updates for Apple accessories, update your Apple software.
- Make sure your Mac is awake and started up from the Mac operating system. Some Apple devices can only request extra power when your Mac is awake or started up from macOS.
