As many other software vendors, Parallels Team is working hard on the required tweaks to make sure you can run Parallels Desktop virtual machines on macOS High Sierra, as well as install macOS High Sierra in a virtual machine.
If you intend to install macOS High Sierra preview on your Mac as a host OS and keep using Parallels Desktop for Mac, we recommend you wait for the Parallels Desktop 12 for Mac upcoming update which will bring support for macOS High Sierra.
You may try installing macOS High Sierra preview as a virtual machine in Parallels Desktop 12 for Mac and send us your feedback.
While the work is in progress, here is the list of known issues with the workaround that we have tested in our lab.
|Shared Windows Applications doesn't work.||1. Disable Shared Windows Applications at VM config > Options > Applications > disable 'Share Windows Applications with Mac'; 2. Disable OS Icon at Parallels Desktop preferences > General > Virtual Machine Dock Icons > set 'None'.|
|Cannot install macOS High Sierra to a virtual machine with Apple File System type.||Install a new VM or upgrade from macOS 10.12 keeping HFS+ file system.|
|Video artefacts in a virtual machine running on macOS High Sierra host OS.||No workaround.|
|A VM installed from Mac Recovery partition cannot upgrade to macOS High Sierra.||No workaround.|
|Cannot install Parallels Tools to macOS High Sierra VM.||No workaround.|
