Six months later, Build 2 is released. Instead of re-downloading the 20 GB image, you download an "UPD" file (usually delta.update).

Workflow for the update:

One of the greatest challenges of the exclusive Qcow2 ecosystem is software updates. Apple issues security and feature updates (e.g., macOS 13.5.1 to 13.6) as delta packages that expect a genuine Apple system volume. When you run a pre-built Qcow2 image with a modified bootloader and custom NVRAM, the native “Software Update” pane often fails—either because the update checks for genuine Apple T2 chip signatures or because the snapshot mechanism in Qcow2 conflicts with APFS sealed volumes.

Thus, exclusive download providers have invented their own update delivery models: Error: qemu-img: Could not open backing file: No

The exclusivity here is not technical but logistical. Maintaining a library of macOS Qcow2 images across versions (from High Sierra to Sequoia) for multiple architectures (x86_64 vs. experimental ARM via QEMU’s qemu-system-aarch64) is labor-intensive. Providers use “exclusive” as leverage for subscriptions or donations.

Before diving into the download, let’s address why QCOW2 is superior to traditional .vmdk (VMware) or .vdi (VirtualBox) files for macOS on non-Apple hardware (Hackintosh) or ARM-based Linux hosts. Search string for forums: "macOS Sonoma qcow2 exclusive"
