Disk Image Options
Among the options for the disk image’s volume inclue:
- The volume’s name
- The volume’s icon
- The file system format
- The capacity of the volume.
- Encryption (None, AES 128, or AES 256)
- Compression
Making a disk image “Internet Enabled” tells web browsers like Safari that the dmg can be treated just like a .zip file would be when downloaded. When Safari has the “Open ‘safe’ files after downloading” option turned on, the contents of zip files and internet-enabled disk images are automatically extracted and put into the user’s Downloads folder, and the zip/dmg file is deleted. Normally a dmg would mount a volume onto the desktop and the user would have to manually copy the files from the mounted volume to their hard drive.
