Can someone from the Parallels team please step in here and provide an estimated timeline for then Parallels will properly support macOS Big Sur? I have been watching this thread for weeks and frankly it's embarassing that the one Parallels person on here seems to keep encouraging people to pursue these hacks despite the support page saying "no workaround." Let's just be frank - it doesn't work right now! We all know it. So just be open about it and let us know when it might work (weeks? months?) rather than lead people on to think that through a series of hacks they can make this functional.
I concur and endorse this comment. I pay a subscription to use Parallels and they need to advise progress with a timeline of when an update will be made available.
