Mac OS X has a command, called “uptime,” which shows how long your computer has been running since it was last rebooted. To see this command in action, go to the Applications folder, open the Utilities folder, and launch Terminal. Once in Terminal, type the word uptime — nothing else is required — and your Mac should tell you how many days, hours and minutes it has been running, how many users are logged in, as well as some obscure information on how hard it is working at that particular moment. Many people still believe that Macs crash dozens of times per day, but this particular Mac has been running for four months.
