Apple Quietly Deprecates hdiutil in Upcoming macOS 27

The long-standing command-line utility for mounting and creating disk images is being phased out, according to early documentation for macOS 27 'Golden Gate.'

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.

Why it matters: Countless build scripts, CI pipelines, and software installers depend on hdiutil under the hood, so any replacement will force real migration work across the Mac developer ecosystem. Apple has a history of giving short runways between deprecation and removal, so teams that rely on .dmg packaging should start auditing their tooling now.
