macOS High Sierra 10.13.6 DMG — What it is, why it matters, and how to use it
You might ask: Is a DMG from 2018 still considered "new"?
In the context of macOS, "new" means unmodified and digitally signed by Apple. Over the years, many third-party websites have injected malware, adware, or modified installers into old DMG files. A "new" DMG refers to one that matches the original SHA-1 checksum provided by Apple’s servers. It is a pristine, untouched copy of the installer.
If you are trying to revive a Mac from the Unibody era (2008-2012) or the Trash Can Mac Pro (2013), yes. High Sierra 10.13.6 is the final resting place for that hardware.
Finding a "new" DMG ensures you have the combo update pre-included. It saves you from downloading 5 security updates and 2 Safari updates immediately after a fresh install.
