MacBook USB port failures can be fixed at home!

Despite the quality standards of Apple devices, it is normal that from time to time a fault can affect their performance. Of course, not all errors deserve a visit to authorized centers, but we can do a diagnosis on our ownhow does it happen when the USB-C ports of the MacBook do not work.

What to do if a USB device doesn’t work with your Mac

Apple recommends several options when Mac USB ports don’t work

The first thing is opt for the classic restart of the computer, because this can help somewhat “shock” the Mac back into working order. If that doesn’t work, the second option is to try reset the System Management Controller (SMC)which controls the MacBook’s power, battery, fans, and other functions.

The steps below only work on MacBook with Apple T2 security chipswhich includes the following models:* MacBook Air introduced in 2018 or later.* MacBook Pro introduced in 2018 or later.

Try to do a reboot of the MacBook. This will not cause you to lose any data or files; it’s just a way to restart your Mac that’s a bit more useful than just restarting it.

  1. Click the Apple menu and then click Shut down
  2. Hold down the power button for 10 seconds.
  3. Release the power button.
  4. Wait a few seconds.
  5. Press the power button again to turn on your Mac. Once your Mac is charged, check to see if the USB-C ports are working. If not, it’s time to move on to the next step.

Reset System Management Controller on your MacBook

The SMC is responsible for a few different aspects of your MacBook o MacBook Pro, including how energy is distributed on your MacBook, including the USB-C ports. So if one or more of your ports are not working, resetting the SMC might fix the problem.

  1. Click on the Apple menu in the upper left corner of your screen.
  2. Click on Shut down…
  3. Hold down Control-Option-Shift for 7 seconds.
  4. Hold down the power button as well as the other keys. If your Mac is on, this will shut it down.
  5. Press all four keys for another 7 seconds.
  6. Press the power button to turn on your Mac.
  7. Now you can check all your USB-C ports to see if they are working.

This would be the second option with which everything is expected to work. If that’s not the case, and your USB-C ports still aren’t working, it’s probably the a more complex error that requires the attention of authorized repair centers.
