How to Get macOS High Sierra 10.13 (ISO & DMG) for Legacy Hardware or Virtual Machines

Body:

Need to run macOS High Sierra 10.13 on older hardware or inside a virtual machine (VMware/VirtualBox)? Apple has removed this version from the main App Store “Purchased” tab for many accounts, but you can still obtain the official installer files directly from Apple using the command line.

Here are the two safest ways to get the OS.

Option 1: Official DMG/App (Best for Real Macs) You can download the original Install macOS High Sierra.app directly from Apple using a terminal command (if you have a valid URL from Apple’s catalog). Once downloaded, you can create a bootable USB or convert it to an ISO yourself using Disk Utility.

Option 2: Creating an ISO from the Installer (Best for VMs) If you have the official .app file (or a trusted DMG), you can convert it to a bootable ISO using Terminal:

  1. Right-click Install macOS High Sierra.app > Show Package Contents.
  2. Navigate to Contents/SharedSupport.
  3. Find the InstallESD.dmg file.
  4. Use the hdiutil command in Terminal to convert that DMG into a standard ISO.

Where NOT to download from: Avoid generic “MacOS High Sierra ISO Download” sites from 2019. They often add spyware, outdated Clover bootloaders, or corrupted partitions. Stick to Apple’s servers or known-good MD5 checksums from community forums.

Final Note: High Sierra (10.13) reached End of Life in 2020. It receives no security updates. Only install this on an offline machine or for specific legacy software testing.

Do you need a ready-to-use ISO for VMware, or just the official Apple installer? Let me know below.

Warning: Downloading OS images from third-party sources (like Archive.org or software repositories) carries risks. Always verify the checksum if possible and scan the files for malware.
