How to Download macOS High Sierra 10.13.6 DMG File (Official & Safe Methods)

macOS High Sierra (10.13.6) remains one of the most significant macOS releases, officially supporting the last generation of polycarbonate MacBooks and introducing the APFS file system to the masses. Whether you need to reinstall an older Mac, downgrade from a newer macOS version, or set up a virtual machine, obtaining the installation file can be tricky since Apple often hides older OS versions from the App Store.

Here is a guide on how to download the macOS High Sierra 10.13.6 DMG file safely.

Method 1: The Official Apple Route (App Store Link)

This is the safest method. It downloads the installer directly from Apple's servers.

  1. Check Compatibility: Ensure your Mac is compatible (MacBook Pro mid-2010 or newer, iMac late 2009 or newer, etc.).
  2. Use the "Hidden" Link: Apple often removes High Sierra from the main App Store search. You must use the direct support page link.
    • Search Google for "Apple kbase DL2089" or "Download macOS High Sierra 10.13.6 Update" to find the official Apple Support page.
    • Alternatively, search for "macOS High Sierra" in the App Store on an older Mac that cannot run Mojave or later; it will usually appear.
  3. Download: Click "Get" or "Download."
    • Note: This usually downloads an Installer Application (approx 5.2GB), not a DMG file directly. Once downloaded, the installer will launch automatically. Quit the installer if you only want the file.

🔧 Step 2: Extract the “InstallESD.dmg” from the installer (if you really need a DMG)

Once the installer downloads (it will appear in /Applications as Install macOS High Sierra.app):

  1. Right-click the .app → Show Package Contents.
  2. Go to Contents → SharedSupport.
  3. You’ll see a file named InstallESD.dmg – that’s the full system image.
  4. Copy it anywhere you like.

This DMG can be used to:

Use a trusted Mac admin tool

Some open-source tools like MIST (macOS Installer Super Tool) can download old installers directly from Apple’s servers – but they download the .app, not a raw DMG.

Legal & Ethical Considerations

It is legal to download macOS High Sierra 10.13.6 directly from Apple or to copy it from a Mac you own. However, distributing the DMG file on public websites violates Apple’s software license agreement.

If you run a repair shop or a school lab, do not host the DMG on your own server for public download. Instead, point users to Apple’s official App Store link or use Apple’s softwareupdate method.

Pro tip: If you need multiple installs, download once from Apple, then create a bootable USB or a NetInstall image for your organization. download macos high sierra 10.13 6 dmg file

When searching for a download, users often encounter two distinct file formats. It is vital to understand the difference:

If you have the .app file, you can easily convert it to a .dmg or create a bootable drive using Terminal commands.
