Problems launching the App?

Some versions of OS X have technical flaws which can cause App Store licenses you have bought from Apple to become temporarily invalid. This happened on November 11, 2015 and February 14, 2016. See our help page to learn how you can repair your system to let it launch Apps again.

System MonitorSystem Monitor

System Monitor is an application for the menu bar of OS X, designed to inform you unobtrusively about the activity of your computer. You can retrieve up-to-date technical data any time, like process load, CPU temperature, main memory consumption, storage space, disk activity, communication on network interfaces, etc. By positioning the app in the menu bar, as least screen real estate as possible will be wasted. The program monitors your system continuously and is readily available when you need it.

You can easily configure the App to automatically stay in the menu bar of your user account. No “login item” is required, so there are no annoying windows or Dock icons when you log in.

If desired, System Monitor can also simulate the flickering activity lights of hard drives or network sockets in the menu bar. This is possible either in color or —perfectly integrated into the design of OS X— in inconspicuous black-and-white. PC switchers who miss this feature on Macintosh computers can easily retrofit this function with System Monitor.
