  • Compress the installation file using the following command
    "tar -zcvf 602100-installCatalina.tar.gz Install\ macOS\ Catalina.app/"
  •     Note: To compress the installation file, go to the Applications folder (as mentioned in the file path) and execute the above command. Do not execute the command in a different folder.
