You must create it yourself from an official macOS installer (legally obtained).
Example steps (on a Mac):

An ISO file is essentially a digital copy of a physical disc. In the context of macOS, it contains the operating system installation files compressed into a single archive. This format is standard for installing operating systems on virtual machines.
Note: Modern macOS versions (Catalina, Big Sur, Monterey, Ventura, Sonoma, and Sequoia) are all 64-bit. Apple dropped 32-bit support starting with macOS Catalina (10.15). Mac Os Download Iso 64 Bit
Apple provides older macOS versions as .app installers. Here is how to get them legally:
Use the createinstallmedia command inside the .app bundle. Replace MyVolumeName with the actual volume name:
sudo /Applications/Install\ macOS\ Sonoma.app/Contents/Resources/createinstallmedia --volume /Volumes/Install\ macOS --nointeraction
(Adjust the path for your macOS version.)
This process takes 10–20 minutes. It copies all bootable system files into the disk image. You must create it yourself from an official
Downloading a pre-made ISO from third-party websites is risky (malware, modified kernels, lack of updates). If you still want to proceed for VM testing on non-Apple hardware (unofficial/unlicensed):
Example using gibMacOS on Windows:
git clone https://github.com/corpnewt/gibMacOS
cd gibMacOS
python gibMacOS.py
Select a version → downloads .pkg or .dmg → then convert using dmg2img tool to ISO.
Many websites offer "macOS ISO 64-bit ready to download." Proceed with extreme caution: You can find detailed tutorials for each macOS
If you choose this path, verify the SHA-256 hash against known-good values from community forums (e.g., InsanelyMac or MacRumors).
This report reviews the availability, legality, methods, and recommendations related to obtaining a Mac OS (macOS) 64‑bit ISO image. It summarizes official Apple distribution channels, common unofficial approaches, risks, and recommended best practices for individuals and organizations.
If you are looking to install macOS on a virtual machine (like VMware Workstation or VirtualBox) or create a bootable USB drive for a Hackintosh, you’ve probably realized that Apple doesn’t exactly hand out ISO files. Instead, they provide an application installer via the App Store.
For virtualization, you need a specific file format: the ISO. In this guide, we will cover how to obtain the macOS ISO file for 64-bit systems safely and legally.
