I'm using MAC much years, and never needed to use the launchctl command. If mean never, mean in normal usage, of course sometimes needed use it when installing somethings from the macports - for onetime load of startup files or so. I'm wondering, why you need start/stop/restart services. However, you only really need to restart the WindowServer, which handles the graphical part of the system. I just do that in Terminal, with this command: sudo killall -HUP WindowServer Warning: All your opened programs will quit immediately! This is like a restart, but of only the graphical part of the system. Quit your open programs first!

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.
