For over a decade, macOS distributions were primarily handled through the App Store as simple applications (.app). Users could easily convert these applications into DMG files for deployment. However, macOS Big Sur represented a paradigm shift in operating system architecture.
Big Sur introduced the Signed System Volume (SSV), a cryptographic sealing method for the system disk. To support this, Apple moved away from standard application wrappers to a new container format. This technical shift created the misconception that the Big Sur installer is "exclusive" or difficult to obtain in DMG format. In reality, the difficulty lies in the extraction process, which requires elevated privileges and specific tools not available to the average user.
The search for "exclusive" DMG links leads many users to unauthorized software repositories (e.g., software archives, torrent sites). This poses significant security risks. Let’s break down the keyword:

Apple distributes Big Sur via the App Store as a "stub" installer or a full installer depending on the requesting hardware. The full installer is a directory structure containing a "chunk list" (integrity verification) and an InstallESD.dmg or SharedSupport.dmg inside the package contents.
Unlike older macOS versions, these internal DMGs are not standalone installers. They are encrypted and segmented, requiring the InstallAssistant framework to reassemble them.
