Apple Retires an Old Disk Tool in macOS 27, but the Replacement Lacks Key Features

macOS 27 Golden Gate retires hdiutil, a tool for managing disk image files, directing users to diskutil instead. But several hdiutil features have no diskutil equivalent — including options for scrubbing, cross-device copying, and preserving file ownership. Scripts built on these features will need rewriting before Apple removes the old tool entirely.
