Checking the Uptime of your OS X Machine

Uptime, uptime, uptime.  Everyone loves massive uptime, right?

The “Who’s PC has been on the longest without a reboot?” sort of challenges.

Well, finding out the uptime on an OS X machine is quite easy!

If you open a Terminal (by using Spotlight, then searching for Terminal or open Applications/Utilities and double click Terminal) and then type:


… so it looks something like this:

user@mac:~$ uptime
23:46  up 11:55, 3 users, load averages: 0.17 0.21 0.23

There is multiple parts of information from this command.  The part we’re focusing on is the second part:  “up  11:55”.  This means that the machine I’m currently on has been booted up for 11 hours and 55 minutes.

So, what’s your uptime?  How often do you manually restart your computer?  Let me know via comments below!
