How to Download a Verified macOS High Sierra 10.13.6 DMG Getting a verified copy of macOS High Sierra 10.13.6 is essential for ensuring your Mac's security and stability. While many third-party sites offer DMG files, the safest and most reliable way to obtain a genuine installer is directly from Apple. 1. Download via the Mac App Store (Official Method)

This is the only method officially verified by Apple to give you a complete, safe installer. Requirements: A compatible Mac running Safari.

Step 1: Open Safari and go to the official macOS High Sierra App Store link.

Step 2: Click "Get" or "Download." This will open the Software Update settings or the App Store.

Step 3: The installer will download to your /Applications folder as "Install macOS High Sierra.app". 2. Download via Terminal (For Advanced Users)

If you are running macOS Catalina 10.15 or later, you can use a Terminal command to fetch the full installer directly from Apple's servers.

Command: Open Terminal and type:softwareupdate --fetch-full-installer --full-installer-version 10.13.6

Result: The full 4.8GB-5.2GB installer will be placed in your Applications folder. 3. Creating the DMG from the .app File

Apple provides the installer as a .app file, not a .dmg. If you specifically need a DMG (e.g., for virtual machines or bootable media), you can create one yourself:

Manual Extraction: Right-click "Install macOS High Sierra.app" and select Show Package Contents. Navigate to Contents/SharedSupport/ to find the InstallESD.dmg.

Using Mist: Use a third-party tool like Mist to automate the download and DMG creation directly from Apple's servers, which is a community-recommended safe alternative to manual Terminal work. 4. Direct Update Downloads (Delta & Combo) download mac os high sierra 10136 dmg verified

Important Note: There is a typo in your request (10136). The correct version number is 10.13.6 (which is the final, most stable version of High Sierra). The content below reflects the correct, searchable version.

Method 2: Creating a DMG File for Virtual Machines

Users often search for a .dmg file specifically to run macOS in VMware or VirtualBox on Windows or Linux. Apple does not provide a direct .dmg download for the full OS; instead, they provide an .app installer.

To get a verified DMG, you must create it from the official installer. Do not download pre-made DMG files from file-sharing websites (like Mediafire or Mega), as these often contain malware.

How to create your own verified DMG:

  1. Download the official installer using Method 1.
  2. Open Disk Utility.
  3. Go to File > New Image > Blank Image.
  4. Name it "HighSierra" and set the size to at least 8 GB.
  5. Mount the new DMG.
  6. Use the terminal command to create a bootable drive onto this DMG: 
    sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/HighSierra
  7. You now have a verified, bootable DMG file safe for virtualization.

Step 1: Install macadmin-scripts

Open Terminal and run:

git clone https://github.com/munki/macadmin-scripts.git
cd macadmin-scripts
./installinstallmacos.py

Error: “This copy of the Install macOS High Sierra application is damaged”

Cause: The date on your Mac is wrong. Apple’s certificate expired on October 24, 2019. Fix: Disconnect from the internet, set the date back via Terminal:

date 1010101018

(That sets date to Oct 10 2018, 10:10am)

Method 2: Download via Terminal (For IT Pros & Advanced Users)

If you need the specific .dmg or .zip raw file from Apple's CDN (Content Delivery Network), you can sometimes access it via Terminal using the softwareupdate tool. This bypasses the App Store interface entirely. How to Download a Verified macOS High Sierra 10

  1. Open Terminal (found in Applications > Utilities).
  2. Type the following command and press Enter: 
    softwareupdate --fetch-full-installer --full-installer-version 10.13.6
  3. Terminal will contact Apple's servers and download the installer. Note that this usually downloads the .app installer, not a standalone DMG, but it is the most reliable way to get the raw files if the App Store fails.

Step 3: Extract the DMG

Navigate to the folder where the script saved the installer (/Applications or ~/Downloads). Then use the same InstallESD.dmg extraction method described in Method 1.

8. Should You Still Use High Sierra in 2025?

Yes, for specific use cases:

  • You need 32-bit app support (dropped after Mojave).
  • Running legacy hardware (e.g., 2010 Mac Pro).
  • Audio production with old FireWire interfaces.

No, if you care about security. High Sierra hasn’t received security patches since late 2020. Never use it as a daily driver connected to the internet without a firewall and updated browsers (Firefox ESR still supports 10.13).

Final Recommendation

Do not download a raw "DMG" from third-party sites. Instead, use Apple’s official installer package via the App Store link or the softwareupdate terminal command. This guarantees the software is verified, unmodified, and safe to run on your older Mac hardware.

For a secure and verified download of macOS High Sierra 10.13.6, it is highly recommended to use official Apple channels to ensure the installer's integrity. Manual downloads from third-party sites can pose significant security risks. 1. Official Download Methods
