You're looking for a detailed guide on how to download and repackage macOS Sierra 10.12.6 (or 10.12.5, as the process might be similar) DMG file. Before we dive into the process, I have to clarify a few things:

Legality and Ethics: Ensure you're downloading and using macOS Sierra for legitimate purposes, such as installing it on a compatible Mac you own or for virtualization on a machine you have permission to use. Unauthorized distribution or use of macOS is against Apple's terms and conditions.
Direct Download: Directly downloading macOS Sierra from Apple's official website or through the Mac App Store is recommended for most users. However, if you're looking to repack a DMG for specific reasons (like creating a bootable USB on multiple platforms or similar), proceed with caution and ensure compliance with legal requirements.

System Requirements (Before You Begin)

2GB RAM (4GB recommended)
14.3GB free storage
macOS 10.12 supports only 64-bit Intel CPUs

Step 3: Verify File Integrity

Before mounting, check the hash. If the site provides SHA256:

shasum -a 256 /path/to/your/downloaded.dmg

Compare the output. If no hash is provided, be extremely cautious.

The Problem: Why Apple Makes It Difficult to Get Sierra Today

Apple’s official distribution for old macOS versions is fragmented:

Mac App Store – If you never "purchased" (downloaded) Sierra before, it may not appear in your purchased history.
Apple Support Downloads – Only available as a small "InstallAssistant.pkg" that requires a specific, modern macOS to unpack. Direct DMG files are not provided.
Certificate Expiry – Even legitimate older installers fail with "This copy of the Install macOS Sierra application is damaged" due to expired security certificates.

Thus, a repack circumvents these modern roadblocks by re-encapsulating the installer with updated metadata or a script that disables date checks.

Step 4: Mount and Extract

Double-click the DMG to mount it. Inside, you should see either:

Install macOS Sierra.app (the main installer)
A folder with Payload and Packages (repacked structure)

A clean repack will contain an unaltered .app file. Drag it to your Applications folder.

Why Users Look for macOS Sierra

macOS 10.12 Sierra represents a critical threshold in Apple's ecosystem. It was the last version of macOS to support certain hardware, such as the 2009 and 2010 MacBook Pro and iMac models. Consequently, users often seek out the Sierra DMG for two primary reasons:

Hardware Restoration: To breathe new life into a vintage Mac that cannot run Catalina, Mojave, or High Sierra.
Retro Computing & VMs: Developers and enthusiasts often need Sierra to test older 32-bit applications, as later versions of macOS dropped 32-bit support entirely (starting with Catalina).

Method 2: DosDude1’s Patcher (Not a Repack, but Safe)

The developer DosDude1 provides a patcher tool for unsupported Macs. He does not distribute repacks; he provides a script that downloads the official installer from Apple (if available) and patches it locally. Siri Integration : macOS Sierra 10
