If you’re wondering how long your Mac has been turned on and running for, simply launch the Terminal and type the following command into the command line:
uptime
This command will report back your system uptime, telling you how long your Mac has been turned on. You will see something like the following:
10:17 up 10 days, 11:02, 4 users, load averages: 0.34 0.29 0.24
As you can see, this Mac has been running for 10 days and 11 hours and 2 minutes.
16:04 up 37 days, 4:59, 23 users, load averages: 0.38 0.33 0.31
37 days???? what?? i have 4 days and i think thats good
There is a way to find out when it was shut down and turned on. It comes up with a list of a bunch of times, not just one.
You can find out the uptime thru System Profiler -> Software -> Time since boot.
Use istat pro widget. It tells gives you uptime and much more.
This is a regular Unix command works in Mac and in any other Unix/Linux outthere.
