Whether the encryption is a layer outside of or inside of the blkx metadata (UDIF) is unclear from reverse engineered documentation, but judging from the vfcrack demonstration it's probably outside. Version 1 has a trailer at the end of the file, while version 2 (default since OS X 10.5) puts it at the beginning. The encryption layer comes in two versions. The data and resource fork information is probably inherited from NDIF. This 'mish' structure contains a table about blocks of data and the position and lengths of each 'chunk' (usually only one chunk, but compression will create more). The main data is stored in a base64 block, using tables identified by the magic 'mish'. The XML plist contains a blkx (blocks) key, with information about how the preceding data fork is allocated. All values are big-endian ( PowerPC byte ordering) This trailer can be described using the following C structure. The UDIF metadata is found at the end of the disk image following the data.

UDIF supports ADC (an old proprietary compression format by Apple), zlib, bzip2 (as of Mac OS X v10.4), and LZFSE (as of Mac OS X v10.11) compression internally. In hdiutil, these layers are called CUDIFEncoding and CEncryptedEncoding. contain block data) with some added metadata, optionally with one or two layers applied that provide compression and encryption. Īpple disk image files are essentially raw disk images (i.e. The encrypted layer was reverse engineered in an implementation called VileFault (a spoonerism of FileVault). File format Īpple has not released any documentation on the format, but attempts to reverse engineer parts of the format have been successful. Disk images in this format typically have a.

Universal Disk Image Format (UDIF) is the native disk image format for Mac OS X. smi extension are actually applications that mount an embedded disk image, thus a 'Self Mounting Image', intended only for Mac OS 9 and earlier. New Disk Image Format (NDIF) was the previous default disk image format in Mac OS 9, and disk images with this format generally have a. A similar format that supported compression of floppy disk images is called DART. Disk images allow the distributor to control the Finder's presentation of the window, which is commonly used to instruct the user to copy the application to the correct folder.Ī previous version of the format, intended only for floppy disk images, is usually referred to as 'Disk Copy 4.2' format, after the version of the Disk Copy utility that was used to handle these images.

Even as the use of resource forks declined with Mac OS X, disk images remained the standard software distribution format. History Īpple originally created its disk image formats because the resource fork used by Mac applications could not easily be transferred over mixed networks such as those that make up the Internet.

Īn Apple Disk Image allows secure password protection as well as file compression, and hence serves both security and file distribution functions such a disk image is most commonly used to distribute software over the Internet.

The image will not be mounted unless the user indicates agreement with the license.

The Disk Copy application had the ability to display a multilingual software license agreement before mounting a disk image. In Mac OS X v10.2.3, Apple introduced Compressed Disk Images and Internet-Enabled Disk Images for use with the Apple utility Disk Copy, which was later integrated into Disk Utility in 10.3. Disk image files may also be managed via the command line interface using the hdiutil utility. These utilities can also use Apple disk image files as images for burning CDs and DVDs. Īpple Disk Images can be created using utilities bundled with Mac OS X, specifically Disk Copy in Mac OS X v10.2 and earlier and Disk Utility in Mac OS X v10.3 and later. Some of the file systems supported include Hierarchical File System (HFS), HFS Plus, File Allocation Table (FAT), ISO9660 and Universal Disk Format (UDF). Features Īpple Disk Image files are published with a MIME type of application/x-apple-diskimage.ĭifferent file systems can be contained inside these disk images, and there is also support for creating hybrid optical media images that contain multiple file systems. An Apple disk image file's name usually has '.dmg' as its extension. When opened, an Apple Disk Image is mounted as a volume within the Macintosh Finder.Īn Apple Disk Image can be structured according to one of several proprietary disk image formats, including the Universal Disk Image Format (UDIF) from Mac OS X and the New Disk Image Format (NDIF) from Mac OS 9. Apple Disk Image is a disk image format commonly used by the macOS operating system.
