Apple, however, does not natively distribute macOS as an ISO file. When you download macOS from the App Store, it arrives as a .app installer (e.g., "Install macOS Monterey.app"). Sometimes, Apple distributes software as .dmg (Disk Image) files, which are similar to ISOs but proprietary to the Apple ecosystem.
The Disconnect: Virtualization software like VMware Workstation and VirtualBox relies heavily on the ISO format to boot operating systems. Because Apple does not provide a "macOS.iso," users looking to run macOS in a virtual machine must create one themselves or download a pre-converted one from a third-party site.
This is where isoRiver enters the equation. It fills the demand for a file format that Apple refuses to provide directly.
Also by Rogue Amoeba, Loopback is the more technical sibling of Audio Hijack. It allows you to create "virtual audio cables" that combine audio from multiple apps and hardware inputs into a single virtual source. isoriver mac os
Use case: You want to record system audio and your microphone simultaneously as separate tracks for a podcast or gameplay commentary. Loopback makes this trivial, whereas Isoriver cannot do this at all.
Unlike traditional linear or clip-based DAWs, Isoriver introduces a node-based, modular environment. Think of it as a hybrid between a classic mixing console, a modular synthesizer (like VCV Rack), and a non-destructive audio editor.

If you are a developer or power user needing a macOS ISO for virtualization, the safest and most reliable method is to create it yourself using the official installer from the Mac App Store.
Here is the industry-standard process to convert a macOS .app installer into an .iso file using the Terminal. Apple, however, does not natively distribute macOS as
Prerequisites:
The Steps:
You now have a clean, safe, and official Monterey.iso file on your desktop, ready for use in VMware or VirtualBox, without the risks associated with "isoRiver" downloads. The Steps:
