UTM vs Parallels Desktop: Windows 11 on an Apple silicon Mac
UTM gives Apple silicon Mac users a free way to run Windows 11 on Arm. It is a good fit for testing an operating system, keeping a separate development environment, or opening Windows when you only need it occasionally.
Daily Windows use asks more from a virtual machine.
UTM still makes for more setup and VM management in your hands. Its Mac integration is useful but limited compared with Parallels Desktop, and its new DirectX 12 acceleration for Windows is still experimental in the UTM 5 beta at the time of writing. That may be a perfectly acceptable trade-off for a free tool. Once you rely on Windows applications for work, engineering software, or gaming, the difference starts to matter.
This guide looks at what UTM does well, which settings are worth tuning, where its current limits are, and what you gain by moving to Parallels Desktop. It also covers VMware Fusion, VirtualBox, and Whisky so you can see where each option fits.

What UTM does well
UTM has earned its place on Apple silicon Macs because it covers a lot of ground without charging for the software.
On an M-series Mac, UTM can virtualize Arm64 operating systems such as Windows 11 on Arm using Apple's hardware virtualization capabilities. That avoids the much larger performance penalty involved in emulating an operating system built for a different processor architecture.
It can also emulate x86 and x64 systems through QEMU. That makes UTM useful when the goal is not maximum Windows performance but access to an older operating system or another architecture.
Developers can keep disposable Windows or Linux environments away from their main Mac installation. Students can learn how virtual machines work without buying a commercial product. Someone who needs one Windows-only utility a few times a month may decide that a little extra setup is a fair price for free software. UTM also supports useful host-to-guest features through its guest tools, including clipboard sharing, shared directories, dynamic resolution, and Retina display handling.
Where UTM hits its limits
Some UTM problems can be improved with a better VM configuration. Others depend on features of the virtualization platform itself. Knowing which is which can save a lot of troubleshooting.
Windows graphics support is still developing.
Graphics used to be one of the clearest differences between UTM and commercial virtualization software.
That picture changed in 2026. UTM 5 beta introduced experimental DirectX 12 graphics acceleration for Windows 11 on macOS. It is a meaningful step forward, but UTM describes the driver as experimental and notes that game compatibility remains limited. A fresh Windows installation is also recommended when using the new graphics driver.
If your Windows workload depends on stable 3D acceleration, that distinction matters. Parallels Desktop 27 supports DirectX graphics up to 11.1 and OpenGL up to 4.3 in supported Windows 11 virtual machines on Apple silicon. Its graphics stack is intended for production use rather than beta testing. That does not mean every Windows game, CAD package, or GPU-heavy application will run. Windows 11 on Arm still has compatibility limits, and applications that require DirectX 12, unsupported drivers, anti-cheat software, or nested virtualization may not work.
The difference is maturity. UTM now has an experimental route into accelerated Windows graphics. Parallels Desktop has a more established graphics implementation and broader support for applications that depend on it.
Windows installation takes more work in UTM
UTM has a Windows VM wizard, and recent versions can download guest tools automatically. You still need to obtain the appropriate Windows 11 Arm installer, choose the VM resources, set storage, and work through the Windows installation. There is value in that control. If you are learning virtualization or building a VM for a specific test, you may want it.
It is less appealing when your goal is simply to open a Windows application. Parallels Desktop can download Windows 11 on Arm from Microsoft through its installation assistant and configure the VM for your Mac and selected use case. With fewer setup decisions and more of the installation handled automatically, our testing found that users could get to a working Windows desktop up to twice as fast with Parallels Desktop than with UTM.
The exact setup time depends on the Mac, network connection, and Windows configuration, but the practical difference is straightforward: Parallels handles more of the setup for you.
UTM has Mac integration, but not at the same level
UTM can share clipboard content and folders between macOS and a supported Windows guest when the appropriate SPICE guest tools are installed. It also supports dynamic resolution and Retina-aware display settings.
So, the issue is not that UTM has no integration with macOS. The difference is how far the integration goes. Parallels Desktop can place Windows applications alongside Mac applications through Coherence mode, integrate supported Windows apps into the Dock, handle shared files and clipboard content, and provide a more unified Mac and Windows desktop experience. For someone who spends most of the day inside a Windows VM, these are practical differences rather than cosmetic ones.
Snapshot management is another gap
Snapshots are useful before a risky software installation, a Windows update, a registry change, or a development test. QEMU, which sits underneath UTM, has snapshot capabilities.
UTM does not currently expose full snapshot management through its normal graphical interface. That makes rollback less convenient than it is in Parallels Desktop or VMware Fusion, where snapshots are built into the VM workflow. For a disposable testing VM, you may not care. If you regularly experiment with a Windows environment you need to restore, it becomes more important.

UTM settings worth checking before you switch
A slow UTM VM does not automatically mean you need another virtualization product. Configuration matters, particularly when too many resources have been assigned to Windows or when an Apple silicon Mac is running an x86 version of Windows through emulation.
If Windows feels sluggish in UTM, start here:
| Setting | Good starting point | Why it matters |
|---|---|---|
| Windows architecture | Windows 11 Arm64 on Apple silicon | Arm64 can be virtualized directly. Running x86/x64 Windows on Apple silicon requires emulation and carries a much larger performance cost. |
| vCPU | Start around 4 cores for general Windows use, then adjust for the workload | Giving the VM more CPU is not always faster. macOS still needs processor capacity, so assigning every available core can hurt overall responsiveness. |
| RAM | 6-8 GB on a 16 GB Mac for general use | Windows needs enough memory to avoid paging, but taking too much RAM away from macOS creates a different bottleneck. Heavier applications may require more. |
| Windows power mode | Use Best performance when the VM is plugged in and CPU performance matters | Windows power management can reduce performance to save energy. Higher-performance modes also increase power use and heat. |
| Storage | Internal SSD or a fast external SSD | Slow storage can make Windows startup, updates, paging, and application launches feel like CPU problems. |
| Display | Start with UTM's normal scaling; enable Retina Mode only when you need the extra sharpness | UTM notes that Retina Mode increases memory and processing requirements because the guest renders at a higher effective resolution. |
Treat these as starting points rather than fixed rules. A browser-and-Office VM has different resource needs from a compiler, database, or engineering application. The Mac matters too. A 16 GB system has much less room for an aggressively configured Windows VM than a Mac with 32 GB or more.
How Parallels Desktop compares
Parallels Desktop takes a different approach to the same problem. Instead of expecting the user to spend much time building and tuning the VM, it handles much of the Windows setup itself. Windows 11 can be downloaded through the installation assistant, and the VM is configured for the Mac rather than starting as a mostly manual project.
Graphics are another clear distinction. Parallels Desktop 27 supports DirectX 11.1 and OpenGL 4.3 for supported Windows 11 virtual machines. UTM 5 has introduced experimental DirectX 12 support, but it is still beta technology with limited game compatibility.
Parallels also goes further with day-to-day Mac integration. Windows applications can sit alongside Mac applications, files can move between the two environments, and the VM behaves less like a separate computer you happen to be viewing from macOS.
There is one qualification worth making: Parallels does not remove the underlying limitations of Windows 11 on Arm. Some x86 and x64 applications still have compatibility problems. Nested virtualization is not available on Apple silicon, and some newer games will not run because of graphics requirements, architecture differences, or anti-cheat systems. Parallels is therefore not a guarantee that every Windows program will work on a Mac. It removes a lot of the VM friction around the applications that do.

UTM vs. Parallels Desktop vs. VMware Fusion vs. VirtualBox
There are now several credible ways to run Windows 11 on an Apple silicon Mac. Their differences are more nuanced than they were a few years ago. VirtualBox, for example, now supports Windows 11 Arm guests on Arm hosts. UTM has experimental DirectX acceleration. VMware Fusion is free for personal, educational, and commercial use.
The table below reflects the current state of these products rather than older Intel-era comparisons.
| Feature | Parallels Desktop | UTM | VMware Fusion | VirtualBox |
|---|---|---|---|---|
| Windows 11 Arm on Apple silicon | Yes | Yes | Yes | Yes |
| Apple silicon virtualization | Native Arm virtualization | Native Arm virtualization | Native Arm virtualization | Arm virtualization supported |
| Windows 3D graphics | DirectX up to 11.1; OpenGL up to 4.3 | Experimental DirectX 12 in UTM 5 beta; compatibility still limited | DirectX 11 supported in current Apple silicon releases | Experimental 3D acceleration on macOS Arm |
| Windows setup | Windows download and guided automatic installation | Manual installer selection and VM setup | Can obtain Windows; installation remains more hands-on | Manual VM and Windows setup |
| Clipboard sharing with Windows | Yes | Yes with guest tools | Yes in current Apple silicon versions | Guest Additions-dependent |
| Shared folders with Windows | Yes | Yes through SPICE WebDAV | Not currently supported for Windows Arm guests | Guest Additions-dependent |
| Drag-and-drop with Windows | Yes | No comparable integrated workflow | Yes in current Apple silicon versions | Support varies by guest/platform |
| Retina / automatic display handling | Yes | Yes, with configurable Retina Mode and dynamic resolution | Auto-fit resolution supported | More limited on Arm than Parallels |
| VM snapshots | Yes | QEMU supports snapshots, but UTM lacks a full snapshot-management GUI | Yes | Yes |
| Integrated Windows app mode | Coherence mode | No | Unity mode is not available for Windows Arm | No |
| Microsoft-authorized solution for Windows 11 on Apple silicon | Yes | No | No | No |

Other Mac VM options
UTM and Parallels Desktop are not the only choices. VMware Fusion and VirtualBox can both run Windows 11 Arm on Apple silicon today, while Whisky solves a different kind of Windows-compatibility problem without running Windows itself.
VirtualBox: Oracle VirtualBox is free and open source. Older comparisons often describe VirtualBox on Apple silicon as emulation-only. That is no longer accurate. VirtualBox 7.2 added support for virtualizing Windows 11 Arm guests on Arm hosts, including macOS on Apple silicon. Its Apple silicon implementation is still less mature than VirtualBox on x86 systems. Oracle also describes 3D acceleration on macOS Arm as experimental. Best for: people who already know VirtualBox, need a free VM platform, and are comfortable working around newer Arm-platform limitations. It remains particularly useful in environments where VirtualBox is already part of an existing test or development workflow.
VMware Fusion: VMware Fusion has a long history on the Mac and now supports Windows 11 Arm on Apple silicon. Current Apple silicon releases include DirectX 11 support, copy and paste, drag-and-drop, snapshots, and automatic resolution handling. Some features available in the older Intel version do not carry over. Shared folders for Windows Arm guests and Unity mode, for example, are not currently supported. Fusion Pro has been free for personal, educational, and commercial users since late 2024. Best for: developers, technical users, and organizations that already work with VMware tools or infrastructure and want a no-cost desktop hypervisor.
Whisky: Whisky is different from the other products on this page because it is not a virtual machine. It provides a Mac interface for running compatible Windows software through Wine and Apple's Game Porting Toolkit technologies. A full Windows installation is not running in the background. That can make Whisky an attractive option when one specific application or game works well through Wine. Compatibility is application-dependent, though. Software that expects particular Windows drivers, services, APIs, or anti-cheat components may not work. Best for: someone trying to run a known Wine-compatible Windows application without maintaining a complete Windows VM. If you need Windows itself rather than one compatible application, use a virtualization product instead.
Which option should you choose?
Choose UTM when cost and control matter most
UTM makes sense when you want a free Windows or Linux VM and do not mind configuring it. It is particularly useful for operating-system testing, isolated development work, security labs, and occasional Windows access. The arrival of experimental DirectX 12 support in UTM 5 also makes the project more interesting for graphics workloads than older comparisons suggest. For now, people who depend on predictable 3D compatibility should remember that the feature is still experimental.
Choose VMware Fusion when VMware already fits your work
Fusion is a strong free alternative for technical users. DirectX 11 support, snapshots, and VMware's broader virtualization tooling give it advantages over UTM for some workloads. Windows integration on Apple silicon is not as complete as the old Intel version of Fusion, so check the specific feature you need rather than assuming every familiar Fusion capability is available.
Choose VirtualBox when you need a free general-purpose VM
VirtualBox's Apple silicon support has improved considerably. It can now virtualize Windows 11 Arm, making it a legitimate option rather than an Intel-only fallback. Several Arm features are newer or experimental, especially graphics, so it is better suited to users who are comfortable with a more technical setup.
Choose Whisky when you do not actually need Windows
If one Windows application is the whole reason you are considering a VM, check whether it works through Whisky first. Skipping the operating system altogether can be lighter than running a Windows VM. The trade-off is compatibility: Wine-based solutions depend heavily on the individual application.
Choose Parallels Desktop when Windows is part of your regular Mac workflow
Parallels Desktop is aimed at a different point on the spectrum. Someone who opens a Windows VM every few weeks may have little reason to pay for it. Someone who moves between macOS and Windows throughout the day feels the integration differences much more often. The case becomes stronger for graphics-dependent software, Windows business applications, engineering tools such as SOLIDWORKS on Mac, and some Windows games. There is also a support distinction. Parallels Desktop is a Microsoft-authorized solution for supported Windows 11 on Arm configurations on Apple silicon Macs.
Moving from UTM to Parallels Desktop
You do not need to uninstall UTM to see whether Parallels Desktop works better for your applications. Both products can remain on the same Mac. That makes it possible to keep an existing UTM VM while setting up a separate Windows installation in Parallels Desktop.
Setting up a new Parallels VM takes fewer steps:
- Install Parallels Desktop.
- Choose the option to install Windows 11.
- Let the installation assistant download and configure Windows 11 on Arm.
- Activate Windows with an eligible Windows license.
- Install the Windows applications you actually use and test them before changing your existing UTM setup.
Windows licensing is separate from the Parallels Desktop license.
If this is your first Windows VM, the guide to running Windows on a Mac covers the broader setup process.
FAQ
Can UTM run Windows 11 on an Apple silicon Mac?
Yes. UTM can virtualize Windows 11 on Arm on Apple silicon Macs. Use an Arm64 Windows installer rather than an x86/x64 Windows image when performance matters. UTM can emulate x86 systems, but cross-architecture emulation carries much more overhead than running an Arm64 guest on an Arm64 Mac.
Does UTM support DirectX on Mac?
Yes, but only experimentally in UTM5 beta. This is a recent change. Earlier stable UTM releases did not provide accelerated DirectX graphics for Windows guests. UTM currently describes the new Windows graphics driver as experimental and notes that game compatibility is limited. If DirectX support is central to your workload, check the current UTM release status and test the application you need.
Does Parallels Desktop support DirectX?
Yes. Current Parallels Desktop 27 releases support DirectX graphics up to version 11.1 and OpenGL up to version 4.3 in supported Windows 11 virtual machines on Apple silicon. Some Windows applications and games still will not run. DirectX 12 requirements, anti-cheat software, incompatible Windows drivers, and Windows on Arm compatibility can all affect an application independently of Parallels Desktop.
Is Parallels Desktop authorized by Microsoft for Windows 11 on Apple silicon?
Yes. Parallels Desktop is a Microsoft-authorized solution for running Windows 11 on Apple silicon Macs.
Can I keep UTM installed while I try Parallels Desktop?
Yes. UTM and Parallels Desktop are separate applications. You can leave an existing UTM VM in place while creating a new Windows 11 VM in Parallels Desktop. Testing both with your actual Windows applications is often more useful than comparing specifications alone.
How much does Parallels Desktop cost?
Parallels Desktop is paid software with different editions for home users, developers, and organizations. Licensing and edition options can change, so check the current purchase page for pricing. A fully functional 14-day trial is available if you want to test your Windows applications first.
What is the difference between UTM and Parallels Desktop for developers?
Both can run isolated Windows and Linux environments on an Apple silicon Mac. UTM gives developers a free, configurable front end to QEMU and works well when low cost, emulation options, or manual control are more important than desktop integration. Parallels Desktop Pro adds higher VM resource limits, command-line and automation features, networking controls, snapshots, and integrations intended for development workflows. See developer environments on Mac for the current Pro feature set. The right choice depends on the environment you need to reproduce. A developer testing several processor architectures may prefer UTM. Someone who spends every workday inside Windows development tools may value Parallels' integration and management features more.
Does UTM support Windows 11 gaming on Mac?
Yes, but support is limited and experimental. UTM 5 beta now includes experimental DirectX 12 acceleration for Windows, so the answer is no longer a blanket “no.” Game compatibility is still limited, and UTM describes the graphics driver as experimental. Games can also fail for reasons unrelated to the VM's DirectX support, including anti-cheat systems and Windows-on-Arm compatibility. Parallels Desktop supports DirectX up to 11.1, but it has limitations too. Some newer games, DirectX 12-dependent titles, and games with anti-cheat software may not run. Check the specific title before choosing a virtualization platform. The Windows gaming on Mac page covers current Parallels gaming support.
How does VirtualBox compare with Parallels Desktop on Apple silicon?
VirtualBox now supports virtualizing Windows 11 Arm on Apple silicon, so descriptions of it as emulation-only on M-series Macs are outdated. The main difference is maturity and integration. VirtualBox's Arm support is newer, and Oracle describes 3D acceleration on macOS Arm as experimental. Parallels Desktop has a longer-established Apple silicon Windows workflow, more Mac integration, and production graphics support up to DirectX 11.1 and OpenGL 4.3. VirtualBox remains attractive when a free, general-purpose hypervisor meets the requirement.
Is VMware Fusion free?
Yes. VMware Fusion Pro is available free for personal, educational, and commercial use. Current Apple silicon versions can run Windows 11 Arm and support DirectX 11, snapshots, copy and paste, and drag-and-drop. Some older Fusion features do not work with Windows Arm guests, including Unity mode and Windows shared folders.
