This article lists five ways to run Windows 10 on Mac and explains each option's pros and cons. Read more >>

The first two are major methods used by Mac users, and Boot Camp Assistant is the best go-to provided by Apple. Since Boot Camp Assistant is an original utility on your Mac, it's comparably safer to use.

Unlike third-party virtual machine applications, it allows you to install Windows on Mac completely so that you can run macOS or Windows on your Mac with utmost performance. Like running macOS, your Mac will allocate all of the resources to Windows applications. Thus, Boot Camp Assistant is the best idea for playing games and RAM-demanding software such as video editor and 3D graphics.

Virtual Machines mimics the Windows environment to install Windows OS on it and Windows-only apps on the OS. It allows you to run macOS and Windows at the same time, but doing so will influence the performance of your Windows apps.

The only drawback of Boot Camp Assistant is that you can't use macOS and Windows simultaneously like virtual machine software but require a restart to switch between.

Step 1: Preparation before Installing Windows 10 on Mac with Boot Camp Assistant

Before we get started, look through the following checklist to see whether your Mac is ready to install Windows 10 on it.

1. Ensure that your Mac is compatible with Windows 10.

Mac Models compatible with Windows 10:

MacBook (2015 and later)

MacBook Pro (2012 and later)

MacBook Air (2012 and later)

iMac Pro (All models)

iMac (2012 and later)

Mac mini (2012 and later)

Mac Pro (2013 and later)

2. You will need an extra USB flash drive with at least 16 GB of free storage to install Windows if your model falls into this list.

Mac Models requiring a USB flash drive: (earlier than OS X El Capitan)

MacBook (before 2015)

MacBook Pro (before 2015)

MacBook Air (before 2017)

iMac (before 2015)

Mac Pro (before 2013)

3. Update your Mac operating system to the latest available. You can check macOS updates from Apple Logo > System Preferences > Software Update > Check Updates.

4. Make sure your Mac is Intel-based. Boot Camp Assistant is canceled on Macs with M1 Max/Pro chips. If you don’t know which chip your Mac is running, click Apple log > About This Mac to view the information.

5. Prepare at least 64GB free space (Apple suggests 128GB for maximum performance) on your Mac hard drive for Windows installation. You can delete unnecessary files to free up space.

6. Installing Windows on Mac with Boot Camp Assistant won't cause data loss with the correct instruction. But you can back up the crucial files in case if anything goes wrong.

Step 2: Download the Windows ISO File

You need to download a Windows 10 ISO file from Microsoft's official website. Unless you want to customize the look, you don't need to activate Windows 10 with a product key to use it.

  • 2. Scroll down to the Select edition part, click the drop-down menu to select Windows 10, and click Confirm.

Step 6: Switch to macOS from Windows 10

Besides being safe, free, and great for demanding software, another benefit of using Boot Camp Assistant is how easy it is to switch between macOS and Windows.

To switch from Windows to macOS:

  • 1. Click the ^ symbol on the right side of the Windows taskbar, then tap on the Boot Camp icon.
  • 2. Click Restart in macOS in the pop-up. Your Mac will restart and boot into macOS right away.

If you want to go back to Windows, you can restart your Mac and hold down the Option key once the screen turns black. Release the Option key when a boot menu asks you to choose a startup partition. Choose Windows.
