From the application, you’ll be able to enable and disable Menu Bar information cells via an On/Off switch system that looks similarly to the switches in iOS. The application also comes with themes for coloring the application and the ability to change how often the application updates the information about your hardware.
Below are some examples of the Menu Bar cells that expand when you click on the Menu Bar icons. They show very detailed information about your hardware and you can hover your mouse pointer over some of the more visual information to expand it into yet more information.
iStat Menus 4.0 is a must-have for all Mac users interested in making sure their hardware is working how it should be. The developer offers a free 14-day trial from the iStat Menus Web site, however the paid version will only set you back $16.
