I am trying to make my own archive of macOS installers. As you know, Apple has done a terrible job of making these available (you download a .dmg which contains a .pkg which installs the .app but the .app gets assembled by some script in the .pkg so you can’t just extract the .app…YUCK).
Once I have these installer apps, I want to create a way that I can store them securely. I have been using
.tar archives (I haven’t bothered compressing them because I figure the space savings would be minor).
I could use
.zip of course, but it occurred to me that maybe
.dmg is the way to go. I could make them read-only so there’s no worries about something changing on them once I know that they are working, and DMGs sync fine via Dropbox, etc. so it seems like a good option.
Am I missing anything? Any reason to use DMG or not use DMG for this? (These would obviously just be for me, and don’t need to be fancy, just reliable so I know that I can use them later)
