I just spoke with support & they confirmed that Hamachi is NOT supported on Big Sur & they were unable to give a time frame for getting it to work. When installing fresh on a new macbook, the Hamachi program just crashes constantly & we could never even get the main program to show up (just the menu icon which flashes & then eventually disappears). I tried the workarounds/tricks in another thread on this board but they did not help & did not resolve the issue.
I asked for a place on the website (or anywhere) that we could check to see when Big Sur is supported & they were unable to provide that, so I'm leaving this here in hopes that someone in support can provide either that, or just update this thread to let us know that it is compatible.
