hdid(8)                   BSD System Manager's Manual                  hdid(8)

     hdid -- historical mechanism for attaching disk images

     hdid [options] image

     Historically, hdid was both the tool used to attach a disk image and the user process used to load and
     decompress disk image data for the hard disk image (HDI) driver in Mac OS X.  hdid exists only for
     backwards compatibility.

     As of Mac OS X 10.4, hdid invokes
           hdiutil attach -agent hdid
     which causes hdiutil(1) to behave like the historical hdid.  For example, some of hdiutil attach's more
     modern behaviors (such as verifying images which haven't been verified before) are disabled.
     hdiutil(1) should be used instead of hdid.
