A short shell script to automate the process of creating an ISO file of any previous macOS for use with virutalization.
This script will create an iso file from most previous macOS installer files. Those ISOs can then be used to install macOS into most common VM apps like Virtualbox, VMware, or Parallels which struggle with DMG files.
THE SCRIPT HAS TWO REQUIREMENTS: that you've already downloaded a valid macOS installer file and have at least 30GB of free space on your internal HD. Use the following links to grab your installers:
- macOS 14.7 Sonoma
- macOS 13.7 Ventura
- macOS 12.7.6 Monterey
- macOS 11.7.10 BigSur
- macOS 10.15 Catalina
- macOS 10.14 Mojave
- macOS 10.13 HighSierra
- macOS 10.12 Sierra
The download should place the new macOS installer into your /Applications folder. When the download is complete, it will auto-launch. When this happens, just QUIT the installer and then run this script with admin/sudo rights. It will automate making an iso file from any of the macOS installers listed above.
I'll update over time.
