Why does your mac book shut down every time you unplug the charger?

If your MacBook shuts down every time you unplug the charger, it might indicate a failing battery or an issue with the battery connection. The battery may not be holding a charge, or there could be a problem with the power management system. Additionally, outdated software or hardware issues could contribute to this behavior. It's advisable to check the battery's health in the System Information or run a diagnostic test to identify the problem.
