How to check your Mac’s uptime

An interesting thing of MacOS is that you can leave your MacBook in sleep or turn on for couples of days, or even months without the need for a restart. Many MacOS users only restart their Mac when they are forced to do so, like when installing a system update. In this post today, we will show you how you could check your Mac’s uptime since the last restart or bootup, as well as view the reboot and shutdown histories.

When checking your Mac’s uptime, you will know how much time has elapsed since you last rebooted your computer, which would be very helpful in troubleshooting several issues.

Check your Mac’s uptime

You can view this info with the help of a Terminal command or by digging into the System Information app on your Mac, with the latter showing additional information like the load averages.

Method 1: Use Terminal to check uptime

First, you need to open Terminal from /Applications/Utilities folder or quickly launch Terminal through the spotlight. To get your Mac’s current uptime, enter the following in Terminal:

uptime

The next thing you see will be a bunch of entries, promoting you how long it has been since your Mac last reboot or startup. You see the screenshot below.

If you are wondering about “2 users,” that is apart from your own Mac user account, your Mac requires the “root” macOS account to function as well.

Method 2: System Information

Those who don’t know much about Terminal, you should not worry about since there is still another way to figure out your Mac’s uptime. To do so:

  • Click on Apple menu and select About This Mac.
  • Under Overview tab in About This Mac window, click the System Information
  • Click on Software in the left-hand column.
  • You will see the time from last reboot next to “Time since boot” in the right-hand section.

Check the reboot and shutdown histories

MacOS comes with dedicated Terminal commands to check out Mac’s reboot and shutdown histories, and these commands are extremely easy to memorize.
