There can be several different reasons why your USB ports are not working on your Mac. Most commonly, it could be related to a hardware issue, such as faulty ports or a problem with the computer’s logic board.
If you have tried plugging your USB device into multiple USB ports, it’s likely a hardware issue.
If the USB ports appear to be functioning properly, it could be a software-related issue. To determine if this is the case, you will want to start by checking the System Report under the Apple Menu and ensuring that the USB ports are being automatically detected by the system.
If the ports are not appearing in the System Report, your USB ports may be disabled in the System Preferences. To do this, open the System Preferences and select “USB”. Ensure that the “Enable USB Ports” option is selected.
If the USB port is still not working, you may need to reset the macOS NVRAM and SMC. To do this turn off your Mac and hold down the Option, Command, P and R keys while turning on the computer. This will reset a variety of components, and hopefully resolve the issue.
If the issue still persists, you will likely need to take your Mac in to receive repairs. In some cases, faulty USB ports can be replaced, but often times, replacing the computer’s entire logic board may be necessary.
