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, main memory consumption, storage space, disk activity, communication on network interfaces, etc. By positioning the app in the menu bar, minimum screen real estate is wasted. The program monitors your system continuously and is readily available when you need it.
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 Mac computers can easily retrofit this function with System Monitor.
- This version adds full support for macOS 10.15 Catalina.
- Legacy technology has been removed from the App. The minimum required OS version is now 10.11.
- As side effect of adding support for Catalina, System Monitor now strictly follows the guideline not to monitor hidden storage volumes. This avoids confusion with the swap space volume, local Time Machine snapshots, App Translocation volumes, or the data part of the Catalina system volume. When choosing volumes for monitoring free storage space, the App uses enhanced user guidance to present the relationship between physical disks, APFS containers, APFS volume groups, and APFS volumes.
- Intel, 64-bit processor
- OS X 10.11 or later
