A shell script (mkmaciso) plus GitHub Actions workflows that download macOS installers directly from Apple's servers and build bootable ISO or DMG images without needing a Mac. It supports macOS versions from OS X Lion (10.7) through macOS Tahoe (26).

Use cases

  • create a bootable macOS installer ISO for Proxmox or QEMU without owning a Mac
  • build a macOS DMG to flash to USB with Rufus for installing macOS
  • generate macOS installer images via GitHub Actions on hosted Mac runners
  • make a recovery ISO for a macOS virtual machine in VMware or Hyper-V
  • download the full macOS offline installer from Apple's servers on Linux or Windows
  • convert a macOS DMG to VHD or VMDK for virtual machine use

When to choose

  • you need macOS installation media but don't have access to a Mac
  • you want to set up a macOS VM in Proxmox, QEMU, VMware, or Hyper-V
  • you need offline installers or recovery images for a wide range of macOS versions
  • you want to create bootable USB media for installing macOS on real hardware

When to avoid

  • you need to build Hackintosh systems rather than just installer images
  • you want a fully offline tool that doesn't rely on Apple's servers or GitHub Actions
  • you need to modify or customize the macOS installer contents beyond standard images
