While the search implies a need for a specific file format, the safest and only recommended route is to download the official installer via the App Store and convert it. Downloading a pre-packaged DMG from a third-party site poses significant security risks that outweigh the convenience, potentially turning a "free" download into a costly security breach. Do not download a raw DMG from a third-party file hosting site. Use the Apple Support website to find the direct App Store link for Catalina. Download the official installer, and if a DMG or bootable drive is required, use the createinstallmedia terminal command to build it safely. Kaon Cg3000 Firmware Update - 3.79.94.248
