iStatistica system monitor for mac

Unlike many other system monitoring apps for Mac, both status bar menu and Notification Widget include the same functionality.

Mac system monitor provides an easy way to eject external drives, overview your battery statistics, realtime informations about CPU, RAM usage and much more. Network statistics includes external, gateway and local IPs, speed and data rates chart. Just click on the ip address to open it in the default web browser.

You can easily configure iStatistica to automatically stay in the menu bar. Just click settings and enable "Open iStatistica at Login" option. If you prefer using Notification Center widget only, you can safely disable autorun feature. iStatistica in Menu Bar and Notification Center widget can work independently.

Temperature and fan speed monitoring requires installing a free plugin. AppStore apps are very limited in getting cpu, memory, disks temperatures and fan speeds, also disk read/write statistics can be done only in separate app. Thats why plugin is required.

iStatistica speaks most common languages. If you would like to assist us translating mac system monitor, your help is greatly appreciated. Just reach us on Twitter or drop a line at
