Sometimes, you wish you could automatically set your Mac to shut down, sleep or restart. A time-consuming process like installing updates will require you to wake up at dead of night and log off your device. Like always, Apple offers a Mac shutdown timer to automate the process.

Mac Shutdown Timer

The Mac App Store has a number of options, including Timer Boom and Shutdown Timer. In addition, you can shut down via the Terminal. Apple boasts features that allow you to predetermine shutdown at a specific time or within intervals or hours elapsed.

Part 1: Making Your Makeshift Mac Shutdown Timer with Terminal

Method 1: Use Terminal Command

Invoke Terminal to throw together a more adaptable shutdown timer. The shutdown command allows you to screech your Mac into a halt in Terminal. You can tweak this shutdown timer to make the best out of the feature.

  • -h will terminate the machine at a specified time.
  • -r reboots the system
  • -s will automatically make your Mac sleep rather than shutdown

You may want to broaden your shutdown timer possibilities but the above options give you everything you need. If you recall this shutdown path, you can just launch Terminal and type the command to craft a shutdown timer. If you wish to bring your Mac to a standstill in 10 minutes-then enter the following command:

  • sudo shutdown –h +15

This command will launch the shutdown process after fifteen minutes; simply substitute the “10” in the foregoing command with any number of minutes. This command may prompt you to enter the administrator password before executing the instructions. For a restart or sleep timer, the commands look like this:

  • sudo shutdown –r +15
  • sudo shutdown –s+15

Once the command starts running, the Terminal will portray the time of the next shutdown. Closing the window or pressing Control + C in the page revokes the shutdown command.

The shutdown timer created gives you the specific time and date when the shutdown/restart/sleep process will apply. It will give you a process ID called pid in the form of three to four digit number. You can also cancel a preset timer, jot down its pid and type the following command in the terminal, viz. sudo kill (pid number).

Part 2: Generate A Shutdown Timer Desktop Shortcut

If you have a frequent shutdown timer, having a desktop shortcut for it makes life easier.

  1. Launch TextEdit and click on New Document. This thrusts a blank text document into view. If the document is larded with coding jargon, press command + shift + T to access plaintext.
  2. On the top of the text window, enter the following: #!/bin/bash. This signals the operating system to execute the command with Bash.
  3. Hold down return twice, and type the shutdown timer command in the third line like sudo shutdown –h + 10.
  4. Save the file with a simple name. Before hitting Save, ensure you uncheck the box near If no extension is provided, use .”txt. Hit Save.

Making the File Executable

  1. Launch Terminal and alter directory to Desktop by entering cd /Users/ [username]/Desktop and hit enter. Next, punch out chmod 774 shutdowns and hit enter.
  2. Double-click the shutdown desktop shortcut to open Terminal, prompting you to type your user password. After that, the timer will start.
  3. You may want to substitute the default icon of the executable file, click to identify it and hold down command + l. This launches the shortcut’s info page. Open the file you wish to apply in Preview and hold down command + A to highlight all and command + C, which copies it. Go to the info window of the shutdown timer, click on the logo in the upper left corner to select it, and then latch on command + V to paste the file.

Part 3: Other Alternatives to Adjust Time for Your Mac

Option #1 Using Schedule Feature

Use the Schedule option of Energy Saver preferences to adjust the time for your Mac to automatically start up, restart, sleep, shut down, and wake. Go to the Apple menu, select System Preferences, and then hit Energy Saver. Click on the Schedule button, and then use the checkboxes or pop-up menus to predetermine when to startup, restart, shutdown or wake.

Option #2 Using Third-Party Tool

Get dedicated Mac shutdown software to do the job when unattended under for long. Designated software support Soft Shutdown and Hard Shutdown if you've got a stubborn app that you cannot quit. A powerful tool should shutdown securely. You also get all bells and whistles such as termination after a long download or update. Look for customizable features, reliability, and speed.

Option #3 Using Timer

Another option is to use a Timer with a stopwatch, clock utility, and alarm clock. Programmable actions include sleep, restart, shutdown, or wake this computer. Top-flight software includes an easy-to-use and ultra-intuitive interface. Using a professional app gives more possibilities than a shutdown timer.

Part 4: In Conclusion

When you shut down your Mac automatically, it must be awake at the specified time that it’s set to terminate and stay awake for up to 10 minutes beyond that time. If it’s asleep at the scheduled shutdown time, it continues to snooze rather than screech to a halt. If you set it to sleep later than 15 minutes of dormancy, it may continue sleeping before it halts. To steer clear of surprises, tweak it to start up or wake 5 minutes earlier than the scheduled shutdown time. You don’t have to install third-party software unless you thirst for convenient and useful features. You too can share your thoughts on how you implement your scheduled shutdown plan below.
