If a friend has the original InstallESD.dmg from their Apple ID, they can copy it to you (but this technically breaks the license unless it’s a family/shared Apple ID purchase).

If you cannot find a clean InstallESD.dmg, there is one last resort.

Option 1: Apple’s hidden Recovery Server Turn off your Mac. Hold Command + Option + R (Internet Recovery for the OS the Mac shipped with). If the Mac was built in late 2011 or later, it might pull Lion directly from Apple’s servers. This requires high-speed ethernet (WiFi passwords often fail in legacy recovery).

Option 2: DiskMaker X for Lion Developer Julien Lavergne created "DiskMaker X" (formerly Lion DiskMaker). This free utility automates the process of turning a downloaded InstallESD.dmg into a bootable USB. It is much safer than Terminal for novices. Version 3.0.1 specifically handles the DMG structure.

You cannot just copy the DMG to a USB stick. You must restore it to a hidden partition. Here is the professional method.

You will need:

Method A: The "Restore" Method (Simplest)

Method B: The Terminal createinstallmedia (Only for 10.7.4+) Note: Apple only introduced the official createinstallmedia command in Mountain Lion. For Lion, you actually use a hidden command:

sudo /Applications/Install\ Mac\ OS\ X\ Lion.app/Contents/Resources/createinstallmedia --volume /Volumes/LIONUSB --applicationpath /Applications/Install\ Mac\ OS\ X\ Lion.app --nointeraction

But again, this requires the .app file, not just the raw InstallESD.dmg.

While Apple has moved on to APFS file systems and Apple Silicon chips, the InstallESD.dmg remains the key to unlocking the Lion era. Whether you retrieve it officially through the App Store or via an archived backup, understanding how to manipulate this DMG file allows you to preserve the history of Mac computing.
