Frequently asked questions

How do I install the app?

Mount the image, drag the app into the "Applications" folder and launch it. If the system blocks the launch, allow it in "System Settings → Privacy & Security".

The app is damaged or won't launch

Reinstalling from a fresh image usually helps. Make sure your macOS version matches the one listed in the compatibility specs.

How do I update?

Download the new version from the site and install it over the current one — your settings will be preserved.

The download link doesn't work

Try a mirror or a download manager. For large files the browser often drops the connection.

How do I completely remove the app?

Use an uninstaller utility — it cleans up the service files that remain after moving the app to the trash.
