Does the MacBook need to be shut down?

As you continue to use your Mac over time, you may notice a decline in performance due to the build-up of processes and apps that consume your RAM, especially if you have an older Mac. If it has been a few days since your last shutdown, you may notice that your Mac isn’t working optimally or is slowing down.


To address this, you can try closing and reopening apps, shutting down unused browser tabs, or restarting your Mac. While macOS is good at managing memory use, sometimes the best way to give your Mac a fresh start is to shut it down and then power it back on. This will clear out the RAM and allow any stuck processes to restart.


Moreover, some updates require a reboot to be applied correctly. By restarting your Mac periodically, you can ensure it stays up-to-date and works smoothly.


Now that we've established whether your Mac needs to be turned off, we’ll take a look at how often you should switch off your MacBook.

How often should you shut down your Mac?

Although it's not mandatory to shut down your Mac every night, it's advisable to restart it once in a while to ensure that it's running smoothly and remains in top condition. So, how often should you shut down your Mac or put it into sleep mode? One way to determine whether to put your computer in sleep mode or shut it down is to consider the duration you'll be away. If you'll be gone for a few hours, it's safe to leave your Mac in sleep mode. But if you plan to be away for several days, you should shut down your MacBook.

Should you turn off your Mac at night?

It’s worth noting that it’s bad to shut down your Mac every day. Contrary to popular belief, there’s no need to shut down your MacBook each night. Some users believe turning off their Mac helps conserve the battery, optimize the device's performance, or prevent component failure. However, none of these claims are entirely true.


It isn’t good to shut down your MacBook every day, as it won’t help save significant amounts of electricity or extend its battery life. Instead, we advise you to put your Mac in sleep mode or enable hibernation mode if you plan to use your MacBook within two to three days.


Frequent shutting down of your MacBook can have negative impacts on your Mac. Usually, when you put your MacBook to sleep, it carries out maintenance and upgrade operations. However, shutting down your device every night prevents these operations from happening.


Furthermore, each time you shut down your MacBook, you’ll have to wait for your computer to boot up and initiate various programs and applications, which can be time-consuming. Plus, frequent turn-offs can affect your Mac's overall performance and cause disruptions to essential processes.

How long should you leave your Mac turned off?

If you're storing a MacBook for an extended period, it's crucial not to leave it fully charged or depleted. Storing a fully charged battery can cause it to lose capacity and decay over time while leaving it drained can result in a deep discharge state where the battery becomes incapable of holding a charge. Thus, it's wise to store the battery with a charge level between 40% and 80% to ensure its longevity.


In addition to battery preservation, there are other best practices to follow when storing your Mac for an extended period. It's crucial to keep it in a dry and cool place, away from direct sunlight and any potential hazards. You should also unplug any peripherals, such as printers or external hard drives, to prevent damage to your Mac's ports.


Before storing it, make sure to update your operating system and backup your data to an external drive or cloud service. By following these steps, you can ensure that your Mac’s in good condition and ready for use when you need it.

Is it better to shut down or sleep for Mac?

When it comes down to the power state of your Mac, you have two main options: sleep mode and shut down mode. Each option has its pros and cons, depending on your needs and preferences. In this section, we’ll explore the features of each mode and provide step-by-step instructions on how to turn them on.

Sleep mode

Sleep mode is a low-power state that allows your Mac to quickly resume from where you left off.


Some features of sleep mode include:

  • Your screen and hard disk turn off to save power
  • Your Mac continues to use a small amount of power to maintain the state of the system
  • You can quickly wake your Mac by pressing a key or clicking the mouse.

Sleep mode is a great option if you need to take a short break from your computer and plan to return soon.


To turn on sleep mode on your Mac, follow these steps:

  1. Click on the Apple menu in the top left corner of the screen
  2. Select Sleep from the drop-down menu or press the Option + Command + Power keys simultaneously
  3. Wait a few seconds for your Mac to enter sleep mode.

Shut down mode

Shut down mode completely turns off your Mac, which can be useful if you plan to be away from your computer for an extended period or if you want to perform maintenance or upgrades.


Some features of shut down mode include:

  • All processes and apps are closed, freeing up system resources
  • Your Mac consumes no power while turned off
  • You need to turn on your Mac manually to use it again.

To turn on shut down mode on your Mac, follow these steps:

  1. Click on the Apple menu in the top left corner of the screen
  2. Select Shut Down from the drop-down menu
  3. Wait for your Mac to shut down completely before turning it off or unplugging it.

A factor to consider when deciding whether to shut down your Mac or put it in sleep mode is the level of security you require. If you're in an environment where there's a high risk of someone gaining unauthorized access to your device, it's best to shut it down when you're not using it.


Also, if you notice that your Mac is running slow or experiencing performance issues, restarting it can help to clear out any background processes and free up memory.


By understanding the features of sleep and shut down modes and knowing how to turn them on, you can better manage the power state of your Mac and ensure it operates optimally.

Favor sleep mode over shutting down your Mac–if you can

So, should you turn off your Mac every night? As we discussed, it's not advised to shut down your Mac each night, but it’s very important to take care of it properly to ensure it runs smoothly. Sleep mode should be your prime option if you plan to use your MacBook again within a day or two, while shutdown mode is ideal if you're planning to be away from your computer for an extended period. Remember to restart your Mac occasionally and clear out the RAM by closing apps or rebooting it.


Whether you should shut down your Mac every night or leave it on depends on your usage and personal preferences. However, consider the potential negative effects of having your Mac on for an extended period, such as overheating, data loss, and security risks. It's always best to create a balance between system health and usage to keep your Mac in top condition.


To further optimize your Mac's performance, you can use tools like MacKeeper's Login Items to manage the apps that launch when you start up your MacBook. This tool can help you identify and remove apps that may be slowing your Mac down or affecting its performance.
