If you're a Mac user who has struggled with compatibility in a post-Intel world, Parallels might just have something special for you: starting with Parallels Desktop 20.2, x86 emulation support for Apple Silicon Macs is here. It’s a significant leap forward in the virtualization space, enabling new functionalities for users of the powerful yet notoriously compatibility-challenged M-series Macs. But hold on—this isn’t perfect just yet. Let’s break this down WindowsForum.com style and explore what this means for the community, including its limitations, the tech behind it, and what you can potentially achieve with it.
This needed a fix. And Parallels has taken its swing with preliminary x86 emulation support to finally allow running full-fledged x86 64-bit operating systems and apps on Apple Silicon Macs.
For everyone else—especially gamers, developers using nested environments, or IT admins depending on advanced hardware acceleration—this is more of a “watch this space” moment. Future versions will iron out bugs, optimize performance, and likely deliver on the promise of a "one-size-fits-all" Mac-powered virtualization.

From Arm to x86: The Compatibility Challenge
Apple's M1 and M2 chips are built on ARM architecture. While offering impressive power efficiency and performance, these chips created hurdles for users who relied on software developed for x86 architecture (think decades of Windows applications). Previously, Parallels Desktop offered virtualization for ARM-based Windows operating systems, which was a nice workaround but left many users wishing for x86 support. Why? Because ARM-based Windows has limited application support—it’s not even in the same league as the tried-and-true x86 version of Windows that developers, IT professionals, and gamers are used to.This needed a fix. And Parallels has taken its swing with preliminary x86 emulation support to finally allow running full-fledged x86 64-bit operating systems and apps on Apple Silicon Macs.
What Exactly Just Changed?
With the Parallels Desktop 20.2 release, users can now emulate x86 processors on M1 and M2 Mac hardware. Here’s what you get:- Supported Operating Systems: Users can create and run x86 versions of Windows 10, Windows 11, and Windows Server. The update even supports contemporary editions like Windows 10 21H2 and Windows Server 2022.
- Linux Compatibility: Certain Linux distros in the x86 family are now possible within this environment.
- Wider App Compatibility: This update widens the roster of compatible Windows applications, including older apps and specific business software that doesn’t yet play nicely with ARM.
- Real-World Use Cases: IT administrators can run tools like Active Directory, developers can test apps in x86 environments, and regular users can run Windows-only software and games—well, potentially.
The Technical Guts: How Does x86 Emulation Work?
x86 emulation essentially translates instructions meant for x86 processors (like Intel and AMD) into ARM-friendly commands that Apple Silicon can work with. Here’s a simplified breakdown:- Dynamic Binary Translation: When you launch an x86 application, the emulator translates the x86 instructions into ARM equivalents, one chunk at a time, as the program executes. Think of it as a real-time interpreter.
- Performance Cost: This translation isn't free—there's a performance penalty because the emulator has to pause and rebuild these instructions constantly. The execution speed is much slower compared to running a native Intel-based Mac or an ARM-specific app.
- Selective Translation: Emulation doesn’t cover the entirety of the x86 instruction set yet. There may be gaps in feature availability depending on your software needs.
Caveats and Limitations: The Rocky Road Ahead
Not all emulation glitters like a remake of gold—this "early access" solution comes with some notable restrictions. Here’s what you should keep in mind before you dive in:- Performance Limitations:
- Booting an emulated x86 system can feel like waiting for Windows XP’s mythical ‘Welcome’ screen to load back in the early 2000s. Expect sluggishness with intensive apps, meaning lightweight tasks are your best bet for now.
- Lack of USB Support:
- Yep, no USB device integration yet. Want to connect your external storage or a USB printer? You’ll have to wait for a future update.
- No Nested Virtualization:
- Features like Windows Subsystem for Linux 2 (WSL2) or running VMware within your virtual machine are not supported. Tech enthusiasts and power users relying on nested virtualization will have to look elsewhere—at least for now.
- 64-Bit Operating Systems Only:
- Forget about running Windows 7 or other older 32-bit operating systems—this emulation is locked firmly into the modern x64 era.
- Hidden Experimental Feature:
- This isn’t on by default. You’ll need to enable the feature manually by right-clicking a virtual machine flagged ‘Not Compatible’ and selecting “Start Using Emulator”. Alternatively, it's accessible via the Parallels Command-Line Interface utility for the script-savvy among you.
Why Does This Matter in the Grand Scheme?
For Mac users—especially those in the professional or enterprise spaces—this could mean liberation from the niche limitations of ARM-based environments. With x86 emulation:- Development Freedom: Developers can finally test against the x86 Windows ecosystem without owning additional hardware.
- Greater App Ecosystem: Compatibility with legacy or specialized software reopens some hefty doors.
- Gaming Potential (But Not Yet): With better performance tuning in the future, running x86 games—plus mods or tools like Steam—on Apple Silicon might just be viable.
So, Is It Worth It?
If you’ve been desperate for a new way to run x86 apps on an M1 or M2 Mac, yes, give it a shot. But know what you’re getting into—think of it as Beta software. More broadly, this step symbolizes a leap forward for virtualization on Apple Silicon, even if it’s not sprinting just yet.For everyone else—especially gamers, developers using nested environments, or IT admins depending on advanced hardware acceleration—this is more of a “watch this space” moment. Future versions will iron out bugs, optimize performance, and likely deliver on the promise of a "one-size-fits-all" Mac-powered virtualization.
Final Thoughts
Parallels Desktop 20.2 introduces a landmark feature with enormous implications for Mac users, but it’s also very much a work in progress. While the shiny banner of x86 emulation will turn heads, don’t expect flawless performance just yet. Still, it’s a glimpse into a future where Apple Silicon-powered Macs might just be as versatile as their Intel predecessors, and that’s a future worth cheering for.Have you tried Parallels Desktop’s x86 emulation yet?
