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.

  1. When asked if to confirm that you want to restart your Mac, click Restart to continue. Your Mac desktop or MacBook will restart immediately.
    • If you don't want the windows that are open now to reopen upon startup, deselect the "reopen windows when logging back in" option. [1]
    • According to Martinez, restarting your Mac clears out the cache in your RAM. If your Mac is slow, you can restart it to make sure applications you're no longer using aren't still taking up some of your RAM. Martinez also suggests using Activity Monitor to find out how much memory is being used by applications on your Mac, and giving it a quick restart if too much RAM is in use.

  1. 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]
  2. 2
    Restart 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.

      Warnings

      • Do not hard reboot your Mac unless it's absolutely necessary to do so. Always try to shut your Mac down normally first.
      • Do not use the Terminal method to restart your computer on a regular basis. This method does not give any running processes the time they need to quit normally and save settings, which could result in eventual degradation of the operating system.
