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

USB-C ports are indispensable for linking peripherals and power supplies to your MacBook. When these ports malfunction, it severely hampers the laptop’s operability. In the following discussion, we’ll delve into the probable reasons behind MacBook USB-C Port not working and offer multiple remedies to rectify the issue.

3 Methods to Restore USB-C Ports on MacBook

Before reviewing advanced troubleshooting steps, it’s crucial to rule out simple issues. Start by verifying whether the problem lies with the cable or charger. Test different chargers and devices to eliminate this possibility.

Ensure the power source functions correctly and check for any visible cable or charger damage. Additionally, consider trying alternative power outlets or USB ports to confirm if the issue persists across different sources. Taking these initial steps can help isolate the root cause of the problem and streamline the troubleshooting process, saving time and effort and resolving the issue effectively.

Gradual Troubleshooting Approach

Begin with basic checks to ensure sure port is clean and no debris hinders functionality. If the ports are clean, attempt a straightforward reboot of your MacBook. Sometimes, this simple action can rectify OS-related glitches causing USB-C port malfunctions.

Step 1: Conduct Diagnostics

Your MacBook has diagnostic tools to identify various issues and provide error codes. The process varies based on your laptop model:

  1. For Intel-based MacBooks, initiate diagnostics by pressing the On/Off and D keys until a progress bar appears.
  2. Apple Silicon MacBooks require you to hold down the power button until booting initiates, then release it and press Command and D when Startup Options display.

Save any error codes generated by Apple Diagnostics for future reference in case you need to contact Apple for repair. These codes can provide valuable insight into the underlying issues affecting your device’s performance and functionality, aiding in effective troubleshooting and resolution.

Step 2: Reset NVRAM

To reset non-volatile memory (NVRAM):

  1. Turn off and on your MacBook.
  2. Press Option+Command+R+P simultaneously.
  3. Release the keys upon hearing the loading sound.
  4. Allow the NVRAM diagnostics and automatic error correction process to complete.

Step 3: Reset the SMC

The System Management Controller (SMC) oversees various physical components of your MacBook. Resetting the SMC differs depending on the device model:

  1. For MacBook models from Y2018 onward without an Apple microprocessor, follow the detailed steps involving the Apple symbol, the “Off” button, and specific key combinations.
  2. Newer MacBook models necessitate tapping the Apple menu, selecting Restart, and checking USB-C ports for functionality.

This procedure applies to MacBook Air (2020, 2022), MacBook Pro 13″ (2020, 2022), and MacBook Pro 14″ and 16″ (2021).

Seeking Further Assistance

If none of the troubleshooting steps prove successful, consider reaching out to Apple Support, especially if covered under the AppleCare+ program, for potential free repairs. If all else fails, replacing the USB-C ports using original spare parts available on the Apple Parts website may be necessary.

Alternatively, you can opt for MacBook repair through Apple Parts’s mail service. Simply send your laptop for diagnostics and promptly receive repair cost estimates. Upon payment, your repaired MacBook will be returned within 1–2 days.
