If you’ve used Windows you know that Ctrl + Alt + Delete—now “Ctrl + Shift + Delete“—is what you do when things aren’t going as expected. Like when you go to launch a program and you get a never-ending loading bar. Or when you’re browsing a webpage and the entire browser locks up. Or when nothing works right because you’re using a Windows PC and not a Mac.
- You should only do this if your Mac can’t shut down normally. (Fun fact: Command+Option+Esc is different from the well-known Ctrl+Alt+Delete shortcut on Windows, but it’s actually similar to Windows’ Ctrl+Shift+Escape shortcut, which opens the Task Manager directly without the extra click it takes from Windows’ Ctrl+Alt+Delete screen.).
- Command + Option + Shift + Escape is another great equivalent of Control + Alt + Delete on Mac. It’s a great combination of keys to directly kill the frozen app without taking you to.
But truth be told, even our shiny iMacs and our unibody MacBooks experience some not-so-smooth sailing. On a Windows PC you press three magic buttons to access the Task Manager. Here you can view running applications and processes and end them. But where are the three magic buttons on a Mac?
How to Ctrl Alt Delete on Mac
On a Mac you use the Command key where on a PC you would use Control (or Ctrl). If you were wondering why Ctrl-B didn't make your text bold, chances are you were previously a PC user and didn't.
Turns out they are there—three magic buttons just like Windows. Command + Option (Alt) + Esc.
Pressing these three buttons simultaneously opens the “Force Quit Applications” window. Here you’ll see all your running applications and a button that says “Force Quit.”
Simply select the application(s) you want to go nuclear on and click “Force Quit.” Your Mac will take care of the rest.
Pro Tip: You can close multiple apps at once. To select a range of apps hold shift and click the starting and ending apps in the list. To select individual apps, hold command and select the apps you want to close. Then just click “Force Quit.”
Task Manager for Mac
Of course Windows also lets you view running processes in the Task Manager. What about Mac? Because Mac is Unix-based you could fire up the Terminal app. Or you could save yourself some work and open the Activity Monitor app.
Activity Monitor is a fantastic tool. You can view which processes are taking up the most memory, the most processing power, and even the most energy. You can also view disk and network statistics. The bottom of the window even provides a visual representation of the numbers.
If you ever hear your fan running faster than normal—or notice lag within your apps—Activity Monitor can help you identify which apps are hogging resources; and, even shut them down as needed. Just remember to be careful when closing processes and applications. Especially if you’re not sure what they do.
Ctrl Alt Shift
Click the headings to sort processes. When you want to end a process, you can use the force quit icon in the top-left of the window (it looks like a stop sign with an “x” in it). Just select the process you want to end and click that force quit icon.
Of course there’s always more than one way to bake a cake. In addition to Activity Monitor and the Force Quit Applications menu, you can also click and hold a non-responsive app in the dock and choose “Force Quit” from the contextual menu.
Ctrl-Alt Delete: An Origin Story
Many people think Ctrl-Alt-Delete started with Windows. Truth is it didn’t. Bill Gates adopted the shortcut from IBM. Early IBM computers utilized the keyboard shortcut to soft reboot devices. That being said, Gates has said it was a mistake and that he would’ve preferred a single button. Of course the rest of us probably just dream of a day where we don’t have to use it all.
While pressing Ctrl + Alt (Option) + Delete on a Mac doesn’t do anything, you can use it in the macOS server login screen. Performing the command will present you with an Easter egg which reads “This is not DOS” before restarting the computer.
Other “Windows Shortcuts” on Mac
Here are a few other commands you might want to use that translate a little differently on macOS.
Formatting: Bold, Italic, Underline (Ctrl + B, I, or U)
Make a statement. Whether you’re using Pages or writing a quick email. Generally copying and pasting is pretty straight forward.
Ctrl Alt Shift On Mac
Command + B for bold, Command + I for italic, or Command + U for underline.
Ctrl Alt Shift For Mac
In-Browser Zoom (Ctrl + “-“ or “+”)
In Web browsers and some other applications you can zoom by holding Command and pressing either the plus (+) key to zoom in or the minus (-) key to zoom out.
In many apps—if you have a trackpad or Magic Mouse—you can use pinch-to-zoom to adjust the zoom. Usually Command + 0 will reset the zoom level.
Undo (Ctrl + Z)
Sometimes you just need to take back your last move. Many applications on Mac allow you to undo a command by pressing Command + Z.
You may even be able to “redo” your last move by pressing Command + Shift + Z.
Copy, Cut, and Paste (Ctrl + C, X, or V)
Copying and pasting is a way of life for most people. It’s not so different on Mac. Just substitute the Command key where you see Ctrl.
Find (Ctrl + F) and Print (Ctrl + P)
Pretty much substituting any Ctrl with Command will work for most shortcuts. Command + F will let you search for words in many apps and browsers. And Command + P lets you print the current page if applicable.
Control Alt Delete Mac
You’re sure to be more efficient if you can keep your Mac running smoothly and if you use shortcuts to improve your productivity.
Keep in mind, Command + Alt + Esc shouldn’t be used as a magic fix for all of your macOS problems. If you’re constantly having issues with your Mac, you may want to take a deeper look under the hood or speak with an Apple Certified Technician.
Left Alt Shift
You can use Activity Monitor to help you see which apps are hogging resources and shut them down; and, if they’re apps that shouldn’t be there you may want to try removing them from your device.
As always, be careful you don’t remove system apps or other integral programs. Another way to avoid performance issues is to steer clear of malicious apps that disguise themselves as antivirus software.
