If you are looking for a direct download link (DMG) because you cannot use the Terminal method above, the "best" alternative is not a random Google Drive link, but a trusted tool that pulls files from Apple.

Tool Recommendation: MIST (macOS Installer Super Tool) MIST is an open-source app that lets you download any macOS version as a DMG or ISO directly from Apple's servers.

  • Click Download. The app will download the chunks from Apple, verify them, and build the DMG for you automatically.
  • If you already downloaded a DMG from Google Drive, delete it and run a full malware check; consider reinstalling macOS from an official installer and changing any passwords used on the machine.
  • Prefer official Apple distribution channels for OS installers to ensure integrity and support.

    • If Google Drive links keep failing, use the gibMacOS Python script (by CorpNewt). It downloads directly from Apple’s software catalog and then you can re-upload to your own Google Drive for future use. When you try to get Catalina from the

    git clone https://github.com/corpnewt/gibMacOS
cd gibMacOS
./gibMacOS.command
# Choose Catalina 10.15.7 (index number)

    This yields the same DMG content but without relying on Google Drive. Then upload it to your personal Google Drive for the “best” private download link.

    Fix: Disable Gatekeeper temporarily. In Terminal:
    sudo spctl --master-disable
    Then try opening the DMG. Re-enable with sudo spctl --master-enable.
