DiskImageMounter is the utility that handles mounting disk images in Mac OS X, starting with version 10.3. Like BOMArchiveHelper it has no GUI when double-clicked; in fact, doing so does nothing. It is found in /System/Library/CoreServices/DiskImageMounter.app. DiskImageMounter works by either launching a daemon to handle the disk image or by contacting a running dæmon and have it mount the disk. The only GUI the program ever displays is a window with a progress bar and mount options (cancel or skip verification) or an error report on why it could not mount the image.
