Reset SMC On A Mac With A T2 Security Chip There are a few ways to reset your SMC depending on your computer, so make sure you know the details of your Mac before we begin. This is our next recommendation for fixing a Mac that won’t charge. Resetting the System Management Controller, or SMC, will help with issues responsible for power, battery, and other components. If this number is at the maximum for your specific Mac, then this could be why your Mac won’t charge. Under the Battery Information section, you’ll see your Mac’s current cycle count under Health Information. From there, choose System Information and select Power under the Hardware tab. To see your current cycle count, hold down the Option Key and click the Apple Menu icon. Compare this number with the number in System Preferences to check if your computer’s battery is healthy. Your Mac’s cycle count limit will depend on what Mac you have, but you can reference Apple’s Cycle Count Limit Chart to see your laptop’s limit. We recommend looking at your Battery Health to see if you’ve hit your battery cycle limit. Then, grab an antistatic brush (an unused toothbrush works!) and lightly brush out the inside of the port. To safely clean your computer’s USB port, shine a flashlight into it. If your charger seems to be working normally, it’s possible that there’s dirt or other debris inside your port preventing your Mac from charging. If not, then this indicates that the issue is with your computer. If your Mac charges after any of these switches, then there’s a problem with the original charger. To test this, we recommend trying to charge your computer with a different charger, power outlet, or a different USB-C port in your Mac. It’s possible that your Mac’s charger is causing the problem.
