Parallels vs UTM on Mac: When Free Is Good Enough and When It Isn’t
UTM is a free, open-source virtualization app for Mac. It’s based on QEMU, works on both Intel and Apple silicon, and runs Windows, Linux, and other operating systems. It doesn’t cost anything. It’s been getting better with every release.
Parallels Desktop costs $99 per year. It’s the market-leading Mac virtualization app with 20 years of development behind it.
The question is: what does $99/year actually buy you?
What UTM Is
UTM (https://mac.getutm.app/) is built on QEMU, one of the most widely used open-source emulators and virtualizers in computing. On Apple silicon, UTM uses Apple’s Hypervisor framework for native ARM virtualization (same as Parallels), which means it can run Windows 11 ARM with reasonable performance.
On Intel Macs, UTM uses QEMU’s full-system emulation, which is slower than native.
UTM is available free from the UTM website, or for $9.99 on the Mac App Store (same functionality, the price supports development).
Performance Comparison
On an M4 MacBook Pro, running Windows 11 ARM:
Windows boot time (cold):
- Parallels: ~11 seconds
- UTM: ~38 seconds
Windows 11 overall feel:
- Parallels: Smooth, near-native
- UTM: Functional, some lag - noticeable especially in animations and app switching
Microsoft Office (Word launch):
- Parallels: ~2 seconds
- UTM: ~6 seconds
3D application (basic DirectX):
- Parallels: DirectX 11 supported, smooth
- UTM: Limited DirectX support, 3D apps often fall back to software rendering
The performance gap is real. UTM on Apple silicon has improved substantially, but Parallels is meaningfully faster in everyday use.
Features UTM Doesn’t Have
- Coherence Mode: UTM has no equivalent. Windows always appears in its own window.
- Shared Clipboard: UTM has clipboard sharing, but it’s less reliable than Parallels’ implementation.
- Drag-and-Drop: File drag-and-drop between Mac and Windows is limited in UTM.
- Parallels Toolbox: Not included.
- DirectX 11: UTM has experimental DirectX support, but it’s significantly behind Parallels.
- Deep macOS integration: Spotlight, Notifications, Siri integration don’t exist in UTM.
What UTM Does Well
Price: Free. For users who need Windows occasionally and don’t run demanding apps, this is compelling.
Linux support: UTM is excellent for running Linux VMs on Mac - arguably as good as Parallels for this use case.
Architecture flexibility: UTM can run x86 Windows on an Apple silicon Mac (via emulation, not virtualization) and can emulate many different processor architectures. Parallels is ARM-only on Apple silicon.
Privacy: UTM is open source. For users who want to inspect what the software is doing, UTM’s code is public.
Who Should Use UTM
- Users who only occasionally need Windows and don’t need speed or seamless integration
- Developers who need to run Linux or other OS environments
- Users who need to emulate x86 on Apple silicon (e.g., to run 32-bit Windows apps)
- Anyone whose use case doesn’t justify $99/year
Who Should Use Parallels
- Anyone using Windows daily or near-daily for professional work
- Users who need Coherence Mode (Windows apps on Mac desktop)
- Users running 3D or performance-demanding Windows apps
- Professionals where the time savings from Parallels’ polish justify the cost
Frequently Asked Questions
Is UTM safe to use? Yes. UTM is open source and widely used. It doesn’t contain malware. It’s developed by a small team and available on GitHub.
Can UTM run Windows 11 on Apple silicon? Yes. UTM runs Windows 11 ARM on M-chip Macs using Apple’s Hypervisor framework. Performance is lower than Parallels but it works.
Does UTM support DirectX? Limited DirectX support exists in UTM. Many DirectX-dependent Windows apps (especially 3D ones like Revit or SolidWorks) don’t run correctly in UTM. Parallels has much better DirectX support.
Is UTM better than VirtualBox? On Apple silicon, yes - UTM uses native virtualization while VirtualBox’s Apple silicon support is limited. On Intel Macs, VirtualBox and UTM are more comparable.
Can I run Revit or AutoCAD in UTM? Not reliably. These applications require DirectX support that UTM doesn’t handle well. Parallels is the appropriate tool for demanding 3D professional software.
What’s the Mac App Store version of UTM vs the free website version? Identical software. The $9.99 App Store version is a way to support UTM’s development. The free version from the UTM website is the same application.
