Forcing a MacBook Pro to shut down may be necessary when it’s unresponsive or frozen. There are a few different ways to force a shutdown, depending on the model of MacBook Pro you have. For all models with an Apple T2 Security Chip, press and hold the Control+Option+Power button until the screen goes black. For models without a T2 Chip, press and hold the Power button for 10 seconds. If neither of those methods works, you can try resetting the SMC (System Management Controller). To do this, shut down your MacBook Pro, then press and hold the Shift+Control+Option keys while pressing the Power button. Release all the keys at the same time, then press the Power button again to turn on your MacBook Pro.
Knowing how to force a shutdown can be important in certain situations, such as when your MacBook Pro is frozen and unresponsive. It can also be helpful if you need to restart your MacBook Pro in Safe Mode or reset the SMC.
