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?
