.Older Parallels Desktop versions are not fully optimized and compatible with the new macOS release, Big Sur (11.0). Please check this Knowledgebase Article for known compatibility and resolved issues prior to upgrading to macOS Big Sur. Nov 20, 2020 Parallels Desktop 16 for Mac integrates the largest design update of Apple’s desktop operating system since the debut of OS X, bringing increased graphics performance; and a variety of new integrated features that provide customers with the best Windows-on-Mac experience ever. Parallels Desktop 16 for Mac integrates the largest design update of Apple’s desktop operating system since the debut of OS X, bringing increased graphics performance; and a variety of new. Aug 11, 2020 Downloaded the public beta of Big Sur and let Parallels create an.iso of it. (Host machine is a 2019 16' MBP with 16GB RAM and 512GB SSD i.e., base 16' model, running macOS Catalina 15.5.6). Installation of Big Sur as a VM took a while but completed successfully.
After upgrading a Mac to Big Sur, the “Network initialization failed” message appears when starting a virtual machine. Shut down the virtual machine and quit Parallels Desktop. Open Terminal (Applications Utilities Terminal), copy and paste the following command, and press Enter.
Apple has at last released macOS Big Sur! First previewed at the Apple Worldwide Developers Conference in June 2020, and then finally released to the world in November 2020, macOS Big Sur has had the longest beta development cycle of any macOS release in recent history.
The silver lining: engineers at Parallels® used this time to work in lockstep with their Apple counterparts in an effort to ensure that users will have the best possible Parallels Desktop® experience once migrated to macOS Big Sur.
The greatest amount of Parallels engineering work came in response to a significant change in the underpinnings of macOS Big Sur. As a Mac user, you may have seen dialogs (like the one shown in Figure 1) when using macOS Catalina or macOS Mojave.

The change in the macOS necessitated the re-architecture of Parallels Desktop (seen in Figure 2).

This will allow the trans fluid to heat up first then pass through the external cooler before flowing back to the transmission. A transmission oil cooler is needed if your vehicle requires extra transmission cooling such as towing heavy loads, live in a warm climate area, or often drive in stop and go traffic, you may want to consider installing an aftermarket transmission cooler.
While this figure illustrates what may appear to be a small change, it required the largest amount of engineering work in Parallels Desktop 16 and the equivalent of 25 man-years of engineering effort. This change means that even more of the performance and security of Parallels Desktop will be derived from Apple’s updates to the internal architecture of macOS going forward.
In addition to the work diagrammed in Figure 2, the Parallels engineers have added a number of new features to Parallels Desktop 16, and to bundled products Parallels Toolbox and Parallels Access, including:
- macOS Big Sur support
- 3D support in macOS VMs
Learn more about these features in Video 1.
