System Toolkit

The System Toolkit is an all-in-one information and maintenance app designed for macOS. Keep track of all the important system information and quickly remove all temporary files on your Mac to free up disk space.

The System Toolkit shows the information in the Menu Bar of macOS, in the porgram itself but also shows the information on a configurable Overlay Window or on the predefined Info Panel!

Overlay Window

Just like the menu bar, information can be shown in an overlay window that always stays on top of other windows. You can configure which information is shown.

Info Panel

The Info Panel displays system information conveniently in a predefined panel that always stays on top.

System Toolkit Server

Because apps published in the Mac App Store are not allowed to access the hardware sensors directly, a small helper utility is necessary.

Once the utility is installed, the "Sensors" page is available. On this page you can see the values of all internal hardware sensors:

  • Temperatures
  • Powers
  • Voltages
  • Currents
  • Fan Speeds

The sensor data can also be shown in the menu bar widgets and the overlay window.


If you want to delete the System Toolkit Server, please follow these instructions:

  • Open the Finder and navigate to the folder /Library/LaunchAgents
  • Delete the file com.sascha-simon.toolkitserver.plist
  • Restart your system.
  • Navigate to the folder /Library/PrivilegedHelperTools/
  • Delete the file System Toolkit

The helper application can be downloaded directly from within the app. Go to the Settings page and select "Toolkit Server".

Disk Cleaner

Remove all cached files and free up disk space. System Toolkit removes application and user cache, browser cache and various other unwanted files.

Big File Finder

System Toolkit lets you find big files on your hard disk. You can remove the files diretcly from within the app.

Duplicate Finder

Sometimes copied files are not deleted at the old location and useful disk space is wasted. Reclaim this disk space by finding file duplicates. Different file names do not matter, it is all about the file content.

Privacy Protector

Delete the cookies, download histories, recently visited links, thumbnails and all other private data you may not want your better half to find out about!
