Why Apple Silicon Users Still Need Windows
Apple Silicon Macs have become remarkably capable, and everyday tasks like tax filing, banking certificates, and document signing now work natively on macOS. Yet a number of legacy public services and enterprise tools still demand a Windows environment. Rather than buying a second computer, Apple Silicon users can run Windows 11 side-by-side with macOS using UTM, a free and open-source virtualization tool. This guide walks through the full installation process β from downloading the ISO to configuring shared folders β with zero paid software required. π₯οΈ
Preparing the Windows 11 ISO and UTM
Downloading UTM for Free
UTM is available as a free DMG download from its official site, and an identical paid version exists on the Mac App Store (approximately $12.99) that only adds auto-updates and developer support β no features are removed in the free build. After downloading, open the DMG and drag the app into Applications.
Getting a Legal Windows 11 ARM ISO
Because Apple Silicon uses the ARM architecture, the standard x86/x64 Windows ISO will not boot. Microsoft's official Windows 11 ARM build includes the Prism emulator, which allows x86/x64 applications to run through emulation. A convenient tool called CrystalFetch (available on the Mac App Store) generates a legal ISO: select Windows 11, choose the latest build, pick the Apple Silicon architecture, set language to your region, and download. The ISO is saved to your chosen location in minutes.

Creating the Virtual Machine and Installing Windows
Configuring Memory, CPU, and Storage
Back in UTM, choose Create a New Virtual Machine β Virtualize (native architecture) and select the preconfigured Windows template. Windows 11 officially requires a minimum of 4GB RAM; users on 8GB Macs should test with the 4GB default first, while 16GB+ machines can comfortably allocate 8GB. CPU cores can remain at default. Under Boot ISO Image, browse to the CrystalFetch-generated ISO. Next, assign disk size based on free space on your Mac, and optionally create a shared directory β for example, a folder on the Desktop β to exchange files between macOS and Windows.
Installation and Guest Tools
Press play, hit Enter at the boot prompt, and the Windows installer launches. Select I don't have a product key to install without activation (a valid license is required for long-term use), choose the 64GB virtual disk, and let the automated installation complete. After setup, open File Explorer β This PC β the virtual HD β run the UTM Guest Tools installer to load the correct drivers; the display sharpens immediately. A comparison of virtualization approaches is summarized below.
| Solution | Cost | DirectX Support | Best For |
|---|---|---|---|
| UTM (free) | $0 | Beta (5.05+) | General apps, office, banking |
| UTM (App Store) | ~$12.99 | Beta (5.05+) | Auto-updates, dev support |
| Parallels Desktop | Subscription | Full | Gaming, heavy GPU workloads |
| VMware Fusion | Free tier | Limited | Enterprise environments |

Final Notes and Practical Tips
Once installed, the Windows 11 ARM virtual machine handles everyday tasks β banking plugins, HTS trading software, document viewers, and security certificates β without major issues, though native 120Hz ProMotion is not supported inside the VM, so scrolling may feel less fluid than macOS. Use Capture Input Device (Ctrl+Option) to lock input to Windows when the macOS interface interferes, and use suspend or shutdown from the VM's power menu for convenience. Note that DirectX acceleration is only available from UTM 5.05 beta onward, with driver issues still being resolved. Always activate Windows with a legitimate license for full personalization features.
