As macOS continues to evolve, legacy versions such as High Sierra (10.13.6) remain relevant for maintaining compatibility with older hardware or specialized software. This paper examines the procedural, security, and practical considerations of installing macOS High Sierra 10.13.6 using a Disk Image (DMG) file rather than the standard macOS Installer application from the App Store. Key steps include obtaining a verified DMG, creating a bootable USB installer, and addressing filesystem compatibility issues (HFS+ vs. APFS). The paper concludes that while a DMG-based installation offers flexibility for offline or legacy system recovery, it requires rigorous verification of cryptographic hashes to prevent tampering and ensure system integrity.
To install using a DMG file, you typically need to download the installer, create a bootable USB drive, and then perform the installation. 1. Download the Installer macos high sierra 10136 dmg install
