Find Out More About Your Mac With iStat Menus

This article is more than 10 years old.

Want to know what's going on under the hood of your Mac? Want to know how fast your cooling fans are running, or how much free RAM you have, or even what phase the phase of the moon is? Yes? Well, do I have a tool for you!

The tool is called iStat Menus 4, and it offers a wide array of deep and detailed stats about your hardware and configuration.

See real-time CPU, RAM, and storage settings, along with network information, in-depth battery information, and a mind-boggling array of sensor information, including fan speeds and temperatures.

So as to save you screen space -- important even on that awesome new retina-display hardware -- iStat Menus lives in your menu bar as opposed to cluttering up your screen.

There's a 14-day free trial of iStat Menus 4 available for you to try, after which a full license costs a reasonable $16.

If you're a stats junkie, you'll love this!
