How Long Has My Mac Been On?

How Long Has My Mac Been On? Tutorial and Steps

So here we discuss the How Long Has My Mac Been On?, and after a lot of requests from our users here is a guide about How Long Has My Mac Been On?.

If you’ve ever wondered how long your Mac has been on and running, you can find out exactly how long the computer has been on since the last boot with two different methods available in OS X.

Let’s learn a little more about how long a Mac is on, and also, in theory, how long you could leave a Mac on.

Find out how long a Mac has been on with System Information in OS X

The easiest way to see how long it has been since your Mac was last shut down or started up is to use System Profiler.

  1. Press Command + Spacebar anywhere in OS X and type “System Information” followed by the Return key to launch that app (some earlier versions of OS X call this “System Profiler”)
  2. Select “Software” from the menu list on the side
  3. Look for “Time Since Startup” to see how much time has passed since the Mac was turned on

Time since boot into Mac system information

A command line approach is also possible. Just launch the Terminal and type the following command in the command line to find out exactly how long the computer has been on:

uptime

This command reports the uptime of your system, which tells you how long your Mac has been on, or how long it has been since it restarted. You will see something like the following reported back:

10:17 up 10 days, 11:02 am, 4 users, average load: 0.34 0.29 0.24

As you can see, this Mac has been on and running for 10 days and 11 hours and 2 minutes.

All Macs will of course report different data here, as some people turn off their Macs at night and some people don’t (I never do).

You can get uptime and boot history information here, focusing on the command line approach, it applies to all versions of OS X and all Mac hardware.

How long can a Mac stay on?

Theoretically, you could leave a Mac on all the time and leave it on forever. Yes, it uses electricity, and yes, you have to take that into account. I personally never turn off my Mac unless I travel and don’t use the Mac for many days or else I just leave it on and never turn it off. Sure, I reboot to install software and what not, but that’s about it. I put it to sleep if I take it somewhere, or if I want to turn it off without turning it off. I never actually turn off my Mac, and I’ve never had a problem with that.

So how long can you actually leave a Mac running? It’s hard to say, if you let a Mac sit for years and do nothing, some hardware components may eventually fail, but this can take a very long time. In fact, many Mac servers routinely achieve very high uptimes in excess of a year after being turned on without rebooting or crashing, here’s one that takes over 400 days, for example, and another over 160 days – pretty impressive, right? That’s what you get with stable software on good hardware, it’s another beauty of the Mac.
