Before we get our hands dirty, here’s a word of warning. If you’re wondering how to reboot a MacBook Pro, bear in mind it’s the last resort when all other methods to unfreeze your Mac had failed. Don’t try it too often as it may harm your system. No question, your Mac can handle rapid power losses and your hardware most likely won’t be hurt. What’s at risk though, is your data because each time you force reboot a Mac it affects the consistency of the file system. Now that you’ve been warned, let’s go.

I'm running High Sierra 10.13.6 on a 12 core, 3.46gz Pro from 2009. Boot ROM Version: MP51.0089.B00 As I noted, it was working fine until I did an SMC reset and a Option-Command-PR pram/nvram reset and that seemed to kill it. It was still powered up and fans were running but zero image.

Symptoms your frozen Mac needs a force restart

• Applications are not responding
• Pointer is not responsive
• Loud fan noise
• The screen goes black
• Mac unable to restart

Can you move the cursor? If yes, try this

Before you force restart a Mac, it’s always recommended to first try a software solution.

• Go to the Apple menu
• Choose Restart
• Click Restart in the menu that appears

Two ways to force restart a Mac

The simplest method: hold down the Power button till your Mac shuts down. Press the button again to restart it.

If your Mac hangs for good and the pointer is inactive:
Hold down Control + Command while pressing the Power button.

This is an alternative key combination to force restart a Mac. By the way, if you are on an iMac, the Power button is found on the back of your Mac. Voila!

Is Shut Down any different from Restart?

The difference between Shut Down and Restart is quite self-explanatory. When you perform a restart, your Mac will turn on again loading its previously active apps. As for shut down, your Mac won’t start until you press the Power button again. Interestingly, all new Macs have an automatic reboot feature built-in. So even if you sit and do nothing, your frozen Mac would eventually reboot by itself, though it takes a bit of patience.

How to force shut down a frozen Mac

If you need to force shut down a MacBook Pro or MacBook Air, all you need is again to press a Power button on your Mac’s keyboard.

Press and hold Power button for 2 seconds
Choose Restart, Sleep or Shut Down in the menu that appears

If you don’t want to reload the baggage of your previously opened apps, tick off “Reopen windows when logging back in”. We do recommend you to deselect this option when your Mac is slow in order to lighten the weight on your RAM.

If your Mac won’t shut down:

Press and hold Power button for about 6 seconds
Hold the button until the Mac shuts down.

Needless to say that when you force restart a Mac all your unsaved projects may be lost. It’s unfair, we know.

Why does my Mac keep freezing?

The obvious explanation is your Mac lacks memory. Or to put another way, there are too many active processes running on your Mac. First off, go to Activity Monitor to check your memory usage.

Go to Applications > Utilities > Activity Monitor
Click the Memory tab

Now, look into how heavily your Memory is loaded. Quit apps that eat up too much memory for no reason. While this may work as a temporary solution, it doesn’t stop your Mac from freezing up again. You can either force reboot your Mac each time or opt for a radical solution. Below are a few more ideas you can try.
