What to Do If Your MacBook USB-C Port Not Working

USB-C ports are necessary for connecting peripherals and a power source to your MacBook. Sometimes they stop working, which significantly reduces the functionality of the laptop. Read on to know what to do if the USB-C Port on your MacBook is not working. You will learn about the possible causes of the problem and several ways to solve them.

3 Ways to fix USB-C port on MacBook

First of all, you need to make sure that the problem is not with a cable or charger. Try to use a different charger and connect different devices. If it does not solve the problem and MacBook USB-C ports are not working, follow the steps described in our instructions.

Act simple to complex – first, check if the ports are not contaminated. Make sure no debris is inside and they are not dirty. If the ports are clean, try simply rebooting your MacBook. Sometimes the operating system won't boot correctly, and this step can make the USB-C ports work again. In cases nothing helps, proceed to the next steps.

Step 1. Run Diagnostics

The MacBook has a functional Apple tool that finds various problems and reports them with an error code. Running the diagnostics differs depending on the laptop model.

If you have an Intel-based MacBook, start the MacBook by pressing the On/Off and D keys simultaneously. Release the keys when the progress bar is displayed on the screen.

For MacBooks with Apple Silicon Mac, you need to press the power button and hold it down until booting starts. When Startup Options are displayed on the screen, release the power button and press Command and D on the keyboard.

If Apple Diagnostics finds a problem and returns an error code, save it, write it down or take a screenshot. You will need this information in case you will have to contact Apple for repair.

Step 2. Reset NVRAM

To reset NVRAM (non-volatile memory):

1. Turn your MacBook off and on.
2. Press Option+Command+R+P at the same time.
3. Release them when you hear the loading sound.
4. Wait for non-volatile memory diagnostics and automatic error correction.

Step 3. Reset the SMC

The SMC is responsible for the correct operation of many physical elements of your MacBook. The SMC reset procedure varies depending on the device model.

For MacBook models starting from Y2018 that do not have an Apple microprocessor:

1. Click on the Apple symbol in the upper left corner to open the menu.
2. Press "Off."
3. Press Control+Option+Shift for seven seconds. If your MacBook turns on, continue to hold down the keys.
4. Press the power button additionally to turn off the device.
5. Continue to hold the combination for seven seconds.
6. Wait another 5–7 seconds and then turn on the laptop.

Once the device is powered on, check that the USB-C ports are functional.

On newer MacBook models, the algorithm is as follows:

1. Tap the Apple menu in the top left corner of the screen.
2. Select Restart.
3. Check the USB-C ports for proper operation.

This way is suitable for the below models:

• MacBook Air (2020, 2022);
• MacBook Pro 13" (2020, 2022);
• MacBook Pro 14" and 16" (2021).

If nothing described in the troubleshooting instructions worked, you need to contact Apple Support. It is good if you have the AppleCare+ program installed on your device, which allows you to count on a free repair.
