How to Download macOS High Sierra 10.13.6 (Raw DMG/ISO) Safely

macOS High Sierra (10.13) is widely considered one of the last "golden" versions of macOS. It is the final version to support 32-bit applications natively without compromise, making it a vital holdout for users with older software or legacy Mac hardware.

If you are looking for a Raw download—meaning a DMG or ISO file rather than an App Store installer—you likely need it for a hackintosh build, a Virtual Machine (VM), or to create a bootable drive for a Mac that no longer has a working App Store connection.

Here is how to get it safely and convert it into the format you need.

How to obtain the installer (official & safe methods)

  • App Store / Software Update: Historically, the full macOS High Sierra installer could be downloaded from Apple via the App Store link or Apple support download pages. Apple provides official legacy macOS installers/updates on its support site.
  • Apple Support downloads: Apple’s support pages host Combo updates and stand-alone installers for older macOS versions; checking Apple’s official download catalog is safest.
  • Create bootable USB: Use the official full installer and run the createinstallmedia command in Terminal to make a bootable installer.

Alternatives

  • If security and modern app compatibility matter: upgrade to a newer macOS supported by your Mac.
  • Use virtualization (VMware, Parallels, VirtualBox) to run High Sierra in a sandbox rather than on primary hardware.

🛠 How to use it (raw installer)

  1. After running the .pkg, go to Applications.
  2. Right-click Install macOS High Sierra.app → Show Package Contents → Contents/SharedSupport – there you’ll find InstallESD.dmg (the raw disk image).
  3. Use that .dmg to:
    • Restore to a USB drive (dd or Disk Utility)
    • Deploy in virtualization (UTM, VirtualBox, VMware)
    • Archive offline installation media

Step 2: Mount the DMG and Extract the App

Double-click the .dmg file. Inside, you will typically find a file named Install macOS High Sierra.app. Drag this into your /Applications folder.

Do not run it from the mounted DMG.
