For years, many businesses faced a practical barrier when considering Macs: One critical Windows application could derail the entire plan.
A client might prefer Macs for executives, developers or creative teams, but still depend on Windows-only engineering, financial or line-of-business software. Supporting two separate device fleets added cost and complexity, while replacing a specialized application was often impractical.
That “app gap” hasn’t disappeared, but it’s getting smaller. Improvements in virtualization, Windows on Arm and centralized device management are making it possible to run more professional Windows applications on Apple silicon. For MSPs, the shift creates an opportunity to offer more than basic Mac support. They can design and manage secure environments that give users access to both platforms without maintaining two physical computers.
That demand shows up in independent survey data, too. In a MacStadium survey of 300 U.S. CIOs at Apple-deploying organizations, roughly 7 in 10 said an enterprise-ready way to manage Macs as infrastructure would influence how quickly they expand Apple adoption – the exact gap a structured virtualization and management service can close.
A timely sign of progress
Parallels provided a recent example with the Aug. 21 announcement of Parallels Desktop 27. The release adds a Metal-based graphics driver with OpenGL 4.3 support, expanding the professional Windows applications that can run in virtual machines on Apple silicon Macs.
According to the company, the release supports applications such as ArcGIS Pro, ZWCAD and Blender 4.3. Parallels claims up to 160% (2.6 times) faster OpenGL graphics performance on Macs with M3 chips or newer, and up to 35% faster performance in selected ArcGIS Pro tasks – with overall workflow time falling by as much as 24%.
The release also introduces support for Apple’s Scalable Matrix Extension (SME2) instructions in Linux virtual machines running on M4 and newer Macs – this release doesn’t extend SME2 support to Windows VMs. In tests on an M4 Pro Mac running Ubuntu, Parallels reported AI and machine-learning matrix operations up to 7 times faster and neural-network inference up to 1.75 times faster.
Those figures come from vendor-controlled testing, and results will vary by hardware, workload and configuration. However, the broader trend matters: Workloads that once required separate Windows hardware are becoming more practical in a virtual environment on a Mac.
Microsoft officially recognizes Parallels Desktop as an authorized way to run Arm versions of Windows 11 Pro and Enterprise on supported Apple Silicon Macs, though its guidance cautions that Windows on Arm has limitations, including compatibility restrictions involving certain hardware, applications, DirectX 12, and nested virtualization.
That means virtualization isn’t a universal answer. It does, however, give MSPs another viable architecture to evaluate.
Start with application discovery
The service opportunity begins with an application and workflow assessment, not a product recommendation.
An MSP should inventory the Windows applications a client needs, who uses them and what each workload requires. The assessment should document processor architecture, graphics dependencies, peripherals, drivers, authentication methods, data locations and performance expectations.
Applications can then be divided into four groups:
- Applications that run natively on macOS
- Windows applications that work reliably on Windows on Arm
- Applications that require testing or configuration changes
- Applications that should remain on physical Windows PCs or move to a cloud desktop
This process protects the client from an overly broad migration and gives the MSP a defensible roadmap. A pilot group can validate performance and compatibility before the business commits to a larger rollout.
The assessment should also compare local virtualization with Windows 365 or another cloud-hosted desktop. Microsoft describes Windows 365 Cloud PCs as an alternative for delivering a Windows 11 environment to Macs. Local virtual machines may offer better offline access and responsiveness, while cloud desktops can simplify centralized control and accommodate workloads that aren’t suitable for Windows on Arm.
Standardization makes the service scalable
Configuring virtual machines one at a time won’t create an efficient managed service. MSPs need standardized images, policies and deployment processes.
A golden image can provide each user with an approved Windows configuration, with required applications, security tools, and settings already installed. Parallels’ enterprise edition includes centralized licensing, policy enforcement, golden-image deployment and integration with management platforms such as Jamf and Microsoft Intune.
Its golden-image tools support both traditional image-based deployment and a declarative approach that can use a current Windows Enterprise image from Microsoft or a custom ISO.
For MSPs, a standardized service could include:
- Application compatibility assessments
- Windows license procurement and tracking
- Golden-image creation and maintenance
- Automated Mac and virtual-machine deployment
- Patch and configuration management
- Endpoint security across both operating systems
- Backup and recovery for virtual machines
- User onboarding and offboarding
- Performance monitoring and capacity planning
- Quarterly application and licensing reviews
The result is a repeatable managed endpoint offering rather than a collection of one-off virtualization projects.
Don’t overlook licensing and security
A Mac running Windows creates two operating environments to manage, secure and license.
Microsoft requires a separate Windows 11 Pro license for each Windows instance, including virtual machines. MSPs should verify licensing before deployment and include those requirements in proposals and recurring costs.
Licensing gets more complex at scale. Microsoft authorizes Parallels for running a standard Windows 11 Pro or Enterprise license on Apple silicon, but its commercial virtual-desktop licensing guidance notes that an OEM or retail Windows license typically doesn’t include virtualization rights, with some exceptions – broader rights generally require Software Assurance, Windows Enterprise E3/E5 or an equivalent subscription such as Windows 365. MSPs standardizing on a golden image should confirm which licensing path applies before assuming that a single Windows 11 Pro purchase covers every deployment model; reusing an image doesn’t reduce the number of licenses required.
Security policies also need to cover both the host and guest operating systems. A protected Mac doesn’t automatically make the Windows virtual machine secure. The MSP still needs to manage Windows updates, endpoint detection and response, encryption, application control, user privileges and access to corporate resources.
Data movement deserves special attention. Features that share folders, clipboards, USB devices and network connections between macOS and Windows may improve productivity, but they can also create unintended paths for sensitive information. Enterprise virtualization tools provide controls for restricting those capabilities, but MSPs must configure and monitor them.
Virtual machines should also be tied to organizational control. Parallels, for example, supports encrypted VMs that can be locked to an organization’s license, helping prevent a copied image from running on an unauthorized device.
Turn mixed-platform complexity into recurring revenue
Clients don’t necessarily want more operating systems. They want the freedom to choose appropriate hardware without losing access to critical applications.
That’s where MSPs can add value. They can determine which workloads belong on macOS, which can run locally on Windows, and which should remain in physical or cloud-hosted Windows environments. They can then manage the licensing, deployment, security and support behind that decision.
As the Mac app gap shrinks, mixed-platform computing becomes less of an exception and more of a service-design choice. MSPs that develop a repeatable approach can help clients expand device choice while creating a new source of assessment, migration and recurring managed-services revenue.
