How does one create a DMG of the smallest size for the given folder? I'm referring both to the size of the.dmg file, and to the size of the filesystem when it's later mounted. If I'm compressing a 73MB folder, I'd like both of these to be 73MB + the minimal filesystem overhead. I'd also like the.dmg to be compressed, so that it takes up less. Hdiutil internet-enable -yes 'MyDiskImage.dmg' This should work on any DMG file. If you want users to see your pretty background, you might not want to do this. However, for simple payloads it's a nice way to go. (Of course, some people would prefer to create a ZIP file for this sort of deployment, anyway.). Open up Disk Utility and choose File New Image Image from Folder (or blank image if you want to make an empty DMG file you can add stuff to later). In the window that pops up, select the folder you want to encrypt and click the “Choose” button.
