Downloading and Using Windows 10 ISO on a Mac
Are you a Mac user looking to install or dual-boot Windows 10 on your system? While macOS is powerful and intuitive, sometimes you might need to use Windows-specific software or games. This guide will walk you through the process of downloading a Windows 10 ISO file and using it on your Mac.
Why Use Windows 10 on a Mac?
There are several reasons why you might want to use Windows 10 on your Mac:
- Access to Windows-only software or games.
- Parallels Desktop or Boot Camp Assistant for better performance with Windows applications.
- Testing Windows applications or websites in a macOS environment.
Downloading the Windows 10 ISO File
Before you begin, you'll need to download the Windows 10 ISO file from the official Microsoft website. Here's how:

- Visit the Microsoft Windows 10 download page.
- Click on the 'Download tool now' button and run the downloaded file.
- Accept the license terms and select 'Create installation media (USB flash drive, DVD, or ISO file) for another PC'.
- Choose 'ISO file' and select the language, edition, and architecture (64-bit or 32-bit) for your Windows 10 installation.
- Click 'Save' to download the Windows 10 ISO file to your Mac.
Creating a Windows 10 Bootable USB Drive on a Mac
Once you've downloaded the ISO file, you can create a bootable USB drive using a third-party application like Balena Etcher or TransMac. Here's how to do it using Balena Etcher:
- Download and install Balena Etcher on your Mac.
- Launch Etcher and click on 'Flash from file'.
- Select the downloaded Windows 10 ISO file.
- Insert a USB drive with at least 8GB of storage into your Mac.
- Click on 'Select target' and choose your USB drive. Be careful, as selecting the wrong drive will erase its contents.
- Click 'Flash!' to start creating the bootable USB drive. This process may take a few minutes.
Installing Windows 10 on a Mac using Boot Camp Assistant
Now that you have a bootable Windows 10 USB drive, you can install Windows 10 on your Mac using Boot Camp Assistant. Here's how:
- Restart your Mac and hold down the Option (Alt) key immediately after pressing the power button until you see a Startup Manager window.
- Select the Windows 10 USB drive and press Enter to boot from it.
- Follow the on-screen instructions to install Windows 10 on your Mac. Make sure to select 'Custom: Install Windows only (advanced)' when asked how you want to install Windows.
- Create and format a partition for Windows, then click 'Next' to begin the installation.
- Follow the prompts to complete the Windows 10 installation. Once done, your Mac will reboot, and you can choose to boot into macOS or Windows using the Startup Disk preference pane in System Preferences.
Using Windows 10 with Parallels Desktop
If you prefer to run Windows 10 within macOS without dual-booting, you can use Parallels Desktop. Here's how to install Windows 10 using Parallels Desktop:

- Download and install Parallels Desktop on your Mac.
- Launch Parallels Desktop and click on 'Install Windows' in the welcome screen.
- Select the Windows 10 ISO file you downloaded earlier and follow the on-screen instructions to install Windows 10 as a virtual machine.
That's it! You now know how to download, create a bootable USB drive, and install Windows 10 on your Mac. Whether you choose to dual-boot using Boot Camp Assistant or run Windows 10 as a virtual machine using Parallels Desktop, you can now enjoy the best of both worlds on your Mac.
