Parallels Desktop 20.2 marks a significant advancement in virtualization technology by introducing x86 emulation on Apple silicon Macs. This breakthrough allows users to run Intel-based operating systems and applications on M1 or later Macs, bridging the compatibility gap created by Apple’s transition to its own Arm-based architecture. While this feature is currently in its early stages, labeled as a “technology preview,” it represents a crucial step towards ensuring a seamless experience for users who rely on legacy x86 software.
The x86 emulation capability in Parallels Desktop 20.2 opens doors to a wide range of Intel-based operating systems, including Windows 10, Windows 11 (specific versions), Windows Server 2019/2022, and select Linux distributions. Users can run these operating systems within virtual machines, utilizing a UEFI BIOS, effectively recreating an Intel-based environment on their Apple silicon Macs. Furthermore, the emulation supports the creation of new virtual machines running Windows 10 21H2 and Windows Server 2022, providing users with flexibility in configuring their virtualized environments.
However, the current implementation of x86 emulation comes with certain limitations, primarily related to performance. Boot times can be significantly longer, sometimes stretching up to seven minutes, as the emulation layer translates Intel instructions to be compatible with the Arm architecture. Additionally, external USB devices are not currently supported within the emulated environment, restricting peripheral connectivity. Furthermore, support for Windows 11 is limited to specific versions, with 24H2 currently not supported. While 64-bit operating systems are the primary focus of emulation, users can still run 32-bit applications within the emulated environment. It’s important to acknowledge these limitations to manage expectations regarding the current performance capabilities of x86 emulation.
To avoid potential disappointment among users who do not specifically require x86 emulation, Parallels has opted to hide the option to start such virtual machines. This approach aims to prevent users from inadvertently attempting to run x86-based systems without a full understanding of the performance implications. As the technology matures and performance improves, Parallels is likely to make this feature more readily accessible to a wider user base.
Beyond x86 emulation, Parallels Desktop 20.2 introduces several other notable enhancements. A key improvement is the automatic synchronization of time and time zone within macOS virtual machines running on Apple silicon. This eliminates the need for manual adjustments and ensures that the virtual machine’s clock remains aligned with the host system. Another significant addition is the integration of Apple’s AI-powered Writing Tools into the Windows context menu. This allows users to access these tools, including grammar and spelling correction, directly from within Windows applications such as Word, PowerPoint, and the classic version of Outlook, enhancing productivity and streamlining workflows. Previously, access to these tools required keyboard shortcuts or navigating through the macOS menu bar.
In summary, Parallels Desktop 20.2 introduces a groundbreaking x86 emulation capability, allowing users to run Intel-based operating systems and applications on Apple silicon Macs. While performance limitations exist in this early stage of development, the feature provides a crucial bridge for users reliant on legacy software. Coupled with other enhancements such as automatic time synchronization and integration of Apple’s Writing Tools, Parallels Desktop 20.2 demonstrates a commitment to innovation and a seamless user experience across platforms. As the technology matures, the x86 emulation feature is poised to become a more robust and integral part of the Parallels ecosystem.
