Since our app is so new, both macOS and Windows erroneously flag Task Manager as malware. So long as you download an official release, either from here or our GitHub repository, the installer is malware-free. However, you may have to take the measures outlined in the instructions below to assuage your computer's fears.
Windows
Click the "Windows x64" button above to download (your browser may make it difficult)
SmartScreen may prevent the installer from running. If it does, just click "More Info" and then select "Run Anyway"
Proceed through the installation process
macOS
Click to "macOS Universal" button above to download the app
Open it once downloaded and drag and drop Task Manager onto the Applications folder. Do not close the window yet!
Double click Applications
Right click on Task Manager and select "Open"
Select "Open" again
Once the application has been downloaded to your device, it will let you know when a new update is available and will offer to update itself. You will not need to reinstall in order to update the app.
