If your Mac desktop or Mac laptop is acting sluggish or programs are failing to run, you need to know how to restart your Mac computer. Restarting or rebooting your Mac essentially clears your computer’s memory and starts it up fresh. When you restart your computer, your Mac closes all running programs and offers to save any files you’re working on. After you choose to save any files, your Mac will finally boot up again.

To restart a Mac computer, you have three choices:

• Press the power button (or press Control+Eject) and, when a dialog box appears, click the Restart button.
• Choose the Apple key and then click Restart.
• Press Control+Command+Eject (or Control+Command+Power button).

Pressing the Control+Command+Eject/Power button is the most reliable way to restart a Mac because it doesn’t rely on the Mac OS X operating system.

Restarting a Mac computer isn’t the same as turning the computer on and off, which completely resets it. If you really want to make sure that your computer starts up correctly, turn it off, wait a few seconds, and then turn it on again. If you’re in a hurry, try restarting your Mac, and if that doesn’t fix the problem, you’ll have to turn it off and on again.

If your Mac freezes, restarting might not work. If your Mac is generally acting weird, restarting isn’t your only option. Macs are known not to need a lot of maintenance or troubleshooting, but if restarting (or rebooting) doesn’t work, consider some other basic troubleshooting options for your Mac.

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.

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.
