my m1 MacBook Air isn't charging after update. I've checked the cable, adapter and the ports on MacBook and they are all fine. I've tried charging it after restarting & shutting down several times. But it isn't working. please give me some advice.

Hi,

Your M1 MacBook Air likely has a temporary software/SMC freeze or a battery charging-hold setting triggered by the macOS update.

1. Check for "Optimized Battery Charging"

macOS sometimes pauses charging past 80% or puts charging on hold due to smart battery features.


  • Click the Battery icon in the top-right corner of your screen (or go to System Settings > Battery).
  • Look for a message like Charging on Hold. If it is active, click Resume Charging.

2. Disconnect External Accessories and Hubs

  • Unplug all external monitors, USB hubs, hard drives, or dongles.
  • Plug the Apple USB-C power adapter directly into the MacBook Air without any intermediate docks. Sometimes a connected device or hub draws or blocks proper power negotiation.

3. Reset the System Management Controller (SMC) / Power Management

Unlike older Intel Macs, M1 MacBooks manage power via a built-in self-test, but a deep power cycle can reset the charging controller:


  • Unplug the charging cable from your Mac.
  • Shut down your MacBook Air completely.
  • Close the lid and wait for 30 to 60 seconds.
  • Plug the charger back in, wait a few seconds, and open the lid.

4. Check for Wall Outlet "Line Noise"

  • Unplug the power brick from the wall socket, wait 30 seconds (this resets the adapter's internal overload protection), and plug it back into a different wall outlet or a separate electrical circuit.
  • Avoid using extension cords or surge protectors temporarily to see if the outlet is experiencing line noise.

5. Boot into Safe Mode or Run Apple Diagnostics

  • If the battery still has some charge left, you can run Apple Diagnostics to check if the system flags a hardware fault with the battery or logic board
