The System Toolkit is an all-in-one information and maintenance app designed for macOS.


• System Information
Keep track of all your system loads. This includes CPU load, memory usage, network speeds and -traffic and the open network connections. All information can be shown in both the menu bar extra and the overlay window. Use the Dashboard to take a look at the most important parameters.

• Menu Bar Extra
You can add as many menu bar widgets as you like. Every menu bar widget can be configured to show information.

• Info Panel
The info panel shows the most important information in a separate window.

• Bluetooth Device Battery Levels
The System Toolkit shows the battery levels of Bluetooth devices.
System Toolkit supports Apple peripherals, Apple Audio devices like AirPods and all Beats Earphones.

• Battery Information
You can check the battery parameters on the battery page. This page shows detailed information about the internal battery. If you are using a Mac without battery, this page is hidden.

Besides the information pages, the System Toolkit also offers the following maintenance features:

• Fast Maintenance: Clean your Mac System with a single click!

• Disk Cleaner
The disk cleaner searches your entire hard disk for temporary or cached files that can be deleted to free up some disk space. The categories include application- and user cache, developer cache, browser cache and many more caches.

• Duplicate Finder
Find duplicate files on your system. Use the smart selection to quickly select and delete your duplicate files and free up disk space.

• Big Files Finder
This feature allows you to find big files on your hard disk. Quickly see which files take the most space. The files can be deleted from within the app.

• Privacy Protector
Erase all your private data on your system. Did you visit some website that you do not want your other system users to find out about? Just start the Privacy Protector and erase your footsteps - it cleans the data of all major Web Browsers.

• App Cleaner
Use the App Cleaner to find and remove files that were created and are being used by an app.

App UI Not User Friendly

First of all app launches as a widget in the menu bar so don’t look for it in the dock. Next, for some scans there is nothing to indicate anything is happening you only find out after the scan is complete and the results display.

Developer Response ,


the app launches as a widget in the menu bar, so please check your menu bar. Click the menu bar item to open the main window.
