There are multiple ways to obtain the installer .app file for Mac OSX that we’ll detail for you below:

  1. If you have a pending upgrade to the next minor or patch version of Mac OS:
    • Within Preferences -> Software Update -> Advanced, make sure Download new updates when available is checked but Install macOS updates is not. While you’re still within Software Update, click Update Now but do not install the next version (Restart) until after you’ve created the Anka VM or the Install .app under /Applications will be deleted.
    • You can also use the App Store to download the installer.
  2. On Catalina, you can use softwareupdate: sudo softwareupdate --fetch-full-installer --full-installer-version 10.15.6
  3. Have your local IT department provide a network volume or download links.
  4. Use our Getting Started script, but run it with ./create-vm-template.bash --no-anka-create
