How To Enable Disabled Usb Port On Mac

Share This:

Are you having trouble getting your USB port to work on your Mac? If so, you’re not alone. Many users have experienced this issue and it can be frustrating when you’re trying to transfer data or use a USB device. Fortunately, there are some easy fixes that can help you get your USB port working again and enable the disabled USB port on Mac.

First, it’s important to make sure that the device you’re using is compatible with your Mac. Some USB devices require more power than others, so if your device requires more power than what your Mac can provide, then you might need an external power source or a powered USB or Thunderbolt 3 (USB-C) hub.

Another possible solution is to unplug any unnecessary USB devices that may be connected to the computer. This could free up enough power for the device you are trying to use. You should also make sure that the device is plugged into the correct USB port and that you are using an appropriate cable for the device.

If these solutions don’t work, then try enabling the USB ports via Device Manager. To do this, open up Device Manager by typing “device manager” or “devmgmt” into the Start menu search box and then click on “Universal Serial Bus controllers” to see a list of all the available ports on your computer. Right-click each port and select “Enable” to re-enable them; if this doesn’t work, right-click each again and select “Uninstall” instead. Once all of these steps have been completed, try plugging in your device again to see if it works now.

Finally, if none of these solutions work for you, then it might be time to consider replacing either your Mac or the external device itself as they could be damaged or faulty in some way.

We hope these tips have helped you enable the disabled USB ports on your Mac and get your devices working properly again!

How To Enable Disabled Usb Port On Mac 1

Enabling USB Ports on a Mac

To enable USB ports on your Mac, there are several steps that you’ll need to take. First, make sure all of your USB devices are self-powered rather than using the power from the port. If you’re using multiple devices, try using a powered USB or Thunderbolt 3 (USB-C) hub to give them all enough power. You should also unplug any unnecessary USB devices to ensure that the ports are not overloaded.

Once you’ve done this, plug your USB device directly into your Mac and make sure that you have chosen the right port and cable for it. If your device still isn’t being recognized, restart your Mac as this will usually fix the issue. Finally, if all else fails, check to see if any updates are available for your Mac and install them as they may contain fixes for any issues related to USB ports.

Enabling a Disabled USB Port

Enabling a disabled USB port is a simple process that can be done in a few steps. First, open the Device Manager by clicking the Start button, typing “device manager” or “devmgmt. msc” into the search box, and pressing Enter. Once the Device Manager window has opened, click on “Universal Serial Bus controllers” to view a list of all USB ports on your computer. Right-click each port to enable it and this should re-enable the USB port. If this doesn’t work, then you can try right-clicking each port and selecting “Uninstall” instead. After uninstalling all of the ports, restart your computer to reinstall them automatically and enable them again.

Troubleshooting USB Device Disabling on Macs

USB devices disabled means that your Mac has detected an issue with the connected USB device and is not allowing it to be used. This can occur if the device is drawing too much power, isn’t compatible with your Mac, or is experiencing a hardware issue. To fix this issue, try disconnecting and reconnecting the external device to your Mac, or connecting it to a different port on your Mac.

Troubleshooting USB Recognition on a Mac

To get your Mac to recognize your USB device, you should first make sure the USB device is properly connected to the computer and that all cables are secure. You can then check System Information to see if the device is listed under USB. If not, you can try connecting the device to a different USB port, or even a different computer. You may also need to update any drivers associated with the USB device.

Unblocking Ports on a Mac

Unblocking a port on your Mac is a relatively simple process. First, open System Preferences and select the Security & Privacy option. Select the Firewall tab, then click the Firewall Options button. You’ll see a list of applications that have requested access to your network. To unblock a port, find the application in the list, then click the checkbox next to it so that it reads “Allow incoming connections”. Once you’ve done this, click OK and you’re all set!

Identifying a Disabled USB Port

To know if your USB port is disabled, you can use Device Manager to scan for hardware changes. First, open the Run command by pressing the Windows key + R. Then type ‘devmgmt’ and press Enter. This will open the Device Manager. Next, click on the computer icon and select Action > Scan for hardware changes. This will scan your computer for any changes in hardware including USB ports. If your USB port is disabled, it won’t show up in the list of devices after the scan is complete. If it does show up, then it’s enabled and working properly.

Troubleshooting USB Port Issues

It’s possible that your USB port is not working due to an internal error or issue. Restarting your computer can often help fix this issue, as it gives the computer a chance to reset itself and fix any underlying problems. To restart your computer, in Windows click the Start menu > Power button > Restart, and on a Mac click Apple > Restart. If restarting does not help, then you may need to check for any damaged or loose connections in the USB port itself. You can also try connecting the device to another USB port or another computer to see if the same issue occurs.


In conclusion, USB ports are an essential part of a computer’s setup, allowing for the connection of various external devices. It’s important to ensure that USB ports are enabled and properly functioning so that you can use them without any issues. If you encounter any problems with your USB port, thre are several fixes that you can try to resolve the issue, such as using self-powered gadgets, using a powered USB hub or unplugging unnecessary USB devices. Additionally, it’s important to make sure you are using the right USB port and cable. If these steps don’t help, then you may need to check your device manager or consult with a technician for assistance in getting your USB ports up and running again.
