Jan 30, 2012 Beyond package (.pkg) files, Pacifist will also read and extract from.dmg.pkg.zip.tar.tar.gz.tar.bz2.xar, and even Mac OS X Installer apps. There are plenty of troubleshooting and trick situations where this would be valuable. For example, if you have a installer file of OS X or a dmg you want to explore and extract files.

Composer allows you to rebuild an existing package (PKG, DMG, or MPKG) by converting it to a package source. After converting it to a package source, you can make changes to its contents and save a new copy of the package. Open Composer and authenticate locally. Drag the package you want to convert from the Finder to the sidebar in Composer. I plan to mass deploy a piece of software, (Mathematica), but the.dmg includes a.app file instead of a.pkg file which is what I need. The guide below shows how to do it with Google Chrome, but.

From Wikipedia: A file with the extension .dmg (an abbreviation for disk image) uses a disk image format commonly found on Mac OS X. The format allows secure password protection as well as file compression and hence serves both security and file distribution functions. Its most common function is the distribution of software over the Internet. When opened, DMG files are 'mounted' as a drive within the Finder.
From: Wikipedia .cdr and ISO
ISO image
Filename extension .iso
Uniform Type Identifier public.iso-image
Type of format Disk image
Standard(s) ISO 9660
An ISO image is an archive file (a.k.a. disk image) of an optical disc using a conventional ISO (International Organization for Standardization) format that is supported by many software vendors. ISO image files typically have a file extension of .ISO but Mac OS X ISO images often have the extension .CDR. The name 'ISO' is taken from the ISO 9660 file system used with CD-ROM media, but an ISO image can also contain UDF file system because UDF is backward-compatible to ISO 9660.

Jamf Composer has always had two formats to build installers. The standard pkg and the seemlingly standard (but not) dmg. The pkg option will build a standard pkg installer file, which will install with any system that can install pkg files.
The dmg option will build a standard dmg disk image file, with the payload of the installer as contents. On its own, however, this dmg cannot do anything. The Jamf Pro management system how ever will understand what to do and how to install the files from the dmg to a system. There are certain features in Jamf Pro which can install and distribute files to user directories and templates (called ‘Fill User Templates’ FUT and ‘Fill Every User’ FEU) which only work with dmg installers in Jamf Pro.
However, Jamf themselves have been recommending to use the standard pkg format in favor of their proprietary use of dmg. Also the Composer application is 32-bit and its future is uncertain.
Luckily there are plenty of great other third-party tools to build installer packages. I cover many of them in my book: Packaging for Apple Administrators
In general, it is probably preferable to re-visit your imaging process and rebuild any installer you still may have in dmg format from scratch. However, in some cases that might not be possible or necessary.
Since the Composer generated dmgs contain all the files for the payload in the proper folder structure you can just use the entire mounted volume as your payload root for pkgbuild. You can easily convert a Composer generated installer dmg to a standard pkg with these commands:
1) mount the dmg:
Dmg Vs Pkg Vs App
Dmg Vs Pkg Jamf
this will output a bunch of info, the very last bit is the mount point of the dmg /Volumes/Sample (the name will depend on the dmg)
2) build a pkg with the contents of the mounted dmg as a payload:
Apple Dmg Vs Pkg
This will create Sample-1.0.pkg in your current working directory. (I like to include the version in the pkg file name, but that is entirely optional.)
3) cleanup: unmount the dmg
Obviously this will not work well with other dmgs, such as Full System dmgs, or dmgs downloaded from the web, which contain an app that should be dragged to /Applications to install (use quickpkg for those dmgs).
