If your USB-C Slim Dock for 24” iMac won’t power on or your devices aren’t recognized, try these steps:

• If it has a power adapter, make sure it’s connected.
• Make sure the host cable is firmly connected to your computer’s USB-C/Thunderbolt port.
• Try a different port on your computer.
• Try a different USB-C/Thunderbolt cable.
• On Mac, check System Information to see whether it appears.

If the problem continues after these steps, submit a support request.
