How to Download macOS ISO

Part 1: Why Do You Need to Download macOS ISO?

Apple doesn’t provide an official way to install macOS on virtual machines, VMware, or non-Mac hardware. However, having a macOS ISO file allows you to bypass these limitations and install it hassle-free. A macOS ISO file is an exact copy of the operating system package in a format compatible with various platforms.

You don’t need to download the macOS ISO file if you already have a Mac computer. You can easily create an ISO file of the macOS installed on Mac, and create a bootable image. However, if you don’t, you need to download it from a trustworthy source to install it on the desired non-mac or virtual machine.

An ISO File is similar to a DMG file and both are treated by your Mac as physical media. If you mount it on your Mac, it’ll just show it like you’ve plugged in a physical disk. ISO files are mostly used to replicate the CDs/DVDs to install OS. ISO files are compatible with Windows, and Mac. However, DMG is only readable on Mac, and that way if you’re planning to set up macOS on your PC, you would need a macOS ISO file to install it.

Note:

Make sure to download macOS ISO files from reliable, and trustworthy sources or it can lead to security risks and system instability issues, such as malware or corrupted files. In severe cases, it can also cause permanent data loss.
