How to Reset USB Ports on Your Mac?

Share This:

If you own a Mac, you may have experienced an issue where your USB ports are not working. This can be very frustrating, as it can stop you from connecting to external devices or even charging your laptop. Fortunately, resetting the USB ports on your Mac is a fairly simple process that should resolve the issue in no time.

The first step is to make sure that your USB device is turned on and its cables are properly connected. If your computer has more than one USB port, try switching the device’s cable to another port. If that doesn’t work, you may have to reset the USB ports on your Mac.

To reset the USB ports, open up System Information and disconnect the USB device from your computer. Wait a few minutes, then refresh System Information by clicking File > Refresh Information. Reconnect the USB device and it should appear again in System Information when it’s been reconnected properly.

If this doesn’t fix the problem with your USB ports, try disabling and re-enabling the USB controller by going into Device Manager and right-clicking each of the controllers listed there. Then select Uninstall Device before restarting your computer so Windows can reinstall them automatically, which should effectively reset all of the USB ports on your system.

You can also try using Windows Troubleshooter to diagnose any issues with the USB controller or device driver that could be causing problems with your ports. If none of these steps solve the problem with your Mac’s USB ports, contact Apple Support for further assistance or contact the manufacturer of any external devices for additional guidance if necessary.

Resetting the USB ports on a Mac is usually a pretty straightforward process that should take care of most common issues related to faulty connections or driver errors. So if you’re having trouble connecting to any external devices via one of your Mac’s USB ports, give these steps a try and see if they help get everything up and running again in no time!

Troubleshooting USB Port Issues on Mac

It is possible that you are experiencing a software issue, or it could be a hardware issue. First, make sure that the USB port is not blocked by any debris or dust. Then, restart your Mac and check to see if the USB ports are now working. If they still don’t work, try resetting the System Management Controller (SMC) on your Mac by following these steps:

1) Shut down your Mac
2) Unplug the power cord from the Mac
3) Wait 15 seconds
4) Plug the power cord back in
5) Wait 5 seconds, then press the power button to turn on your Mac

If resetting the SMC doesn’t help, you may need to take your Mac to an Apple Store or an authorized repair center for further diagnosis and repair.

Forcing Mac to Recognize USB

To force your Mac to recognize a USB device, you can try the following steps:
1. Disconnect the USB device from your computer.
2. Open System Information (located in the Utilities folder).
3. Click File > Refresh Information.
4. Reconnect the USB device to your computer.
5. Wait a few minutes for System Information to recognize and list the device in its directory.
If this does not work, you may need to restart your computer or check your USB port for any obstructions that could be preventing it from properly connecting with the device.

Troubleshooting USB Port Issues

If your USB ports are not working, there are several steps you can take to troubleshoot the issue. First, check to make sure the device is properly connected. If it appears that the device is connected correctly, try using Device Manager to scan for hardware changes. To do this, click Start, type devmgmt in the Run box, and press Enter. In Device Manager, click on your computer so that it is highlighted. Then click Action and select Scan for hardware changes. If a USB device is still not working after scanning for hardware changes, you may need to update your USB drivers. To do this, open Device Manager again and right-click on the USB device with an exclamation mark next to it. Select Update Driver from the menu and let Windows search for an updated driver automatically. If no updated driver is found or if the problem persists after updating the driver, you may need to try uninstalling and reinstalling the USB controllers from Device Manager.

Fixing an Undetected USB on a Mac

If your USB device is not being detected on your Mac, there are a few steps you can take to try and resolve the issue. Firstly, inspect the device for any physical damage or wear. If there is any sign of damage, it may be preventing the Mac from detecting the USB device. Secondly, try reconnecting the USB device to a different port on your Mac. This can help bypass any conflicts with existing ports. Thirdly, if possible, plug the USB device into another Mac computer and see if it is detected. This will tell you whether there is an issue with the USB device itself or just your computer. Lastly, check that your USB drivers are up-to-date; if they’re not, update them and see if this solves the problem.

Enabling USB Ports on a Mac

To enable USB ports on a Mac, you will need to follow these steps:
1. Make sure that the USB port is enabled in the System Preferences of your Mac. To do this, open System Preferences and select “USB” from the Hardware section. Here you should be able to find a checkbox labeled “Enable USB” which should be checked if it isn’t already.
2. Determine what type of USB port your Mac has. Macs have both USB-A and USB-C ports, so make sure that you are using the right type of cable for your device.
3. Plug your device into the appropriate USB port on your Mac and check that it is receiving power by looking at the LED lights or other indicators on the device itself.
4. In some cases, you may need to install additional software or drivers for the device before it will work properly with your Mac. Check with the manufacturer of the device for any additional instructions or information about installing any necessary software or drivers for your particular model of the device.
5. Finally, restart your Mac if necessary to ensure that all changes take effect and that any newly installed software or drivers are properly loaded and ready to use with your device(s).

Troubleshooting USB Device Recognition Issues

It’s possible that your USB isn’t being recognized due to a few different reasons. First, it could be that the currently loaded USB driver has become unstable or corrupt. In this case, you may need to update or reinstall the driver. Second, your PC may require an update to address any conflicts between Windows and your USB external hard drive. Finally, there may be other missing updates or hardware/software issues that are causing the issue. To resolve this issue, you should try updating Windows and any drivers related to your USB device, as well as checking for other hardware or software issues.


In conclusion, Mac is a reliable and powerful platform that offers a wide range of features and tools to help you get the most out of your computing experience.
