Apple Quietly Deprecates hdiutil in Upcoming macOS 27
Apple's next major macOS release, reportedly codenamed Golden Gate, marks hdiutil as deprecated, according to a developer who spotted the change in pre-release documentation. hdiutil has been a core part of macOS for decades, used to create, mount, verify, and convert disk image files (.dmg) both interactively and in automated scripts.
The tool is widely relied upon by developers, IT admins, and software distributors who package Mac apps as disk images or build automated deployment pipelines. Apple hasn't yet detailed what will replace it, leaving open questions about backward compatibility for existing scripts and installers.
Deprecation doesn't mean immediate removal, but it signals that Apple wants developers to start migrating away from hdiutil-based workflows sooner rather than later.
