If your Mac computer suddenly becomes frozen or begins to act slow and sluggish, restarting your Mac can help clear its memory and process items at a normal speed upon bootup. There are several ways to restart your Mac, which can be useful in the event you are unable to access certain commands or programs as a result of computer issues. Read on to learn how to restart your Mac, with expert tips from computer and phone repair specialist Gonzalo Martinez.
Ways to Restart a Mac
The easiest way to restart a Mac is by clicking the Apple menu button in the upper-left corner and choosing Restart . You can also use a keyboard shortcut ( Ctrl+Eject or Cmd+Ctrl+Eject ), Terminal, or the power button on your computer. You can also use remote access to remotely restart your Mac.
Steps
-
Press the Ctrl + ⏏ Eject keys on your keyboard at the same time. Depending on your Mac, you might need to hold the power button instead of the eject button. After a few seconds, you will be prompted to restart your Mac. [2] X Research source
-
Select Restart when asked to make a selection. Your computer will immediately restart itself.
-
Restart your Mac with a keyboard shortcut. If your Mac is unresponsive, try pressing Ctrl + ⌘ Cmd + ⏏ Eject to restart it. This command will prompt you to save any open documents to prevent data loss. You can opt to save them or just allow your Mac to close the associated apps automatically. [3] X Research source
-
2Restart your Mac without prompting. If your Mac is unresponsive and you weren't able to reboot it with the previous keyboard shortcut, press the Ctrl + ⌘ Cmd + Power keys all at the same time to restart it instantly without it asking you to verify your command. Your Mac will not prompt you to save any work or close open apps, so you should only use this option if your Mac is unresponsive and the previous shortcut didn't work.
-
1Open Spotlight. You can also use a Linux command in your Mac's Terminal to restart it. Click the Spotlight icon, which resembles a magnifying glass, in your menu bar. This opens the Spotlight search feature.
- Alternatively, you can press ⌘ Cmd + Space to open Spotlight.
- If there is a magnifying glass icon on one of your function keys on your keyboard, pressing that key will open Spotlight as well.
-
2Type terminal and double-click it to open it. When you type "terminal" into Spotlight, it will pull up the Terminal app.
- Be sure to save any open documents before you continue, as you will not be prompted to save your work before your Mac shuts down.
-
Type shutdown -r now and press ⏎ Return . Your computer will restart immediately.
- Alternatively, you can type reboot or reboot -q . Adding the "-q" will forcefully shut down your computer and restart it.
-
Quit any processes that require the use of the hard drive. If your Mac will not restart or shut down any other way, you can perform a hard restart. It's best to do this when there aren't any applications running or files open. You should also avoid hard restarting your Mac if you're actively transferring or downloading files.
-
Press and hold down the power button on your Mac until the computer turns off. Don't lift your finger from the Power button until your Mac is totally off. [4] X Research source This process should take between two and three seconds.
-
Press the power button again to restart your Mac. If your Mac doesn't doesn't restart, wait a few seconds before pressing the power button again.
-
1Click the Apple icon in your toolbar and choose System Settings . Use this method to make it possible for other people to shut down your Mac remotely.
- On older versions of macOS, this will say System Preferences .
-
Click on Sharing . The Sharing option has an icon of a folder with a yellow diamond on it.
-
Place a checkmark next to "Remote Login." It's in the left-hand menu in the Sharing window.
- You can now close the System Settings window.
-
Open a web browser and go to Google. You can also use any search engine that you prefer if you don't like Google.
-
Type "what is my ip" into the search bar and press ⏎ Return . Google will display your IP address at the top of search results.
- Copy your IP address or write it down.
-
Go to another computer that is connected to the same network. This can be a Mac, Linux, or Windows computer.
-
Open the Terminal application. If you're on Windows, you can use Terminal, PowerShell, or the Command Prompt. On Linux or another Mac, just open a Terminal window.
-
Type ssh username@ip_address into Terminal and press ⏎ Return . Replace username with the admin username on your Mac, and replace ip_address with the IP address you copied from Google.
- You will be prompted to enter your password to continue. Once your password is accepted, you'll see a prompt.
-
Type reboot into Terminal and press ⏎ Return . Your Mac will now restart.
