Ok, that's a bit unusual, but there are a few reasons this might be happening — and while macOS doesn't let you directly disable that notification, we can try to address the root cause so it stops showing up.
- Make sure you're using an Apple-certified charger and USB-C cable. Sometimes third-party or lower-wattage adapters can cause the system to detect inconsistent power, even if it's technically charging.
- Debris or corrosion in the USB-C port on your Mac or frayed cable ends can result in intermittent connections.
- If your laptop is using an Intel CPU, try resetting the SMC.
- Check System Settings > Battery, then click Options under Battery Health. Disable *Optimized Battery Charging* temporarily to see if the behavior changes.
- Finally, use System Information to confirm power status:
- Open System Information (from Spotlight or Utilities folder)
- Go to Power and look at what the system reports under “AC Charger Information” and “Charging”.
If your Mac is bouncing between detecting and not detecting the charger, it's possible the power source or charger just isn't reliable enough for macOS to stay quiet about it.
