USB-C ports are used to connect charging and peripheral devices. When the ports stop working, the overall functionality of your MacBook is impaired. In this article, we’ll tell you what to do if a USB-C port stops working. You will also learn the reasons for the failure of these ports and how to solve the problem when MacBook USB C ports not working based on detailed instructions provided.

3 Ways to Fix the USB-C Port on MacBook

First, make sure that the cable or charger is in working order. You can connect another charger to the notebook and test it to see if it works. If this is not the cause, proceed to the steps described in the step-by-step instructions.

Check whether the ports are free of debris and not dirty. If the ports are clean, restart the device. If restarting the operating system does not help, proceed to the other steps below.

Step 1: Run diagnostics on your MacBook

Use the Apple Diagnostics tool that searches for issues and provides an error code if there are any. If you have an Intel-based, start the device by pressing the power and D keys. Release the keys when the Diagnostics start indicator appears on the screen.

If your MacBook has an Apple Silicon Mac, you must press the Power button until booting begins. When the startup options appear, release the button and immediately press Command and D.

If the diagnostic program returns an error code, save it in case you need to contact Apple for repair. You can write it down or take a screenshot.

Step 2: Reset NVRAM

The process of resetting the non-volatile memory is as follows:

1. Turn off and immediately turn on the laptop.
2. Press Option+Command+R+P until the download sounds.
3. Wait for NVRAM diagnostics and error correction.

Step 3: Reset SMC

The System Management Controller (SMC) is responsible for ensuring that numerous parts of your MacBook function properly. SMC reset methods vary depending on your notebook model.

For MacBook models manufactured in 2018 or later:

1. Click on the Apple symbol and click on “Turn off” in the menu.
2. Press Control+Shift+Option for seven seconds.
3. Press the power button without releasing the combination to turn off your MacBook and hold it down for seven seconds.
4. Wait another 5-7 seconds and turn on the laptop.

When it comes to newer MacBook models, the algorithm is even simpler:

1. Open the menu by tapping the Apple icon.
2. Select “Restart”.

This method is applicable to the following MacBook models:

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

If you can’t fix the problem, contact Apple Support. Most likely you will need to replace the USB-C ports. You can find them on the Apple Parts website. The company offers only genuine Apple parts and accessories at affordable prices.
