This worked for me!
I upgraded to Big Sur on the first releases and Hamachi stopped working.
I tried to reinstall on all new beta updates, but without "Allow" button on the Pref panel.
With this trick I was able to successfully install.
Can you please provide us another update? All it takes for you is to contact the Dev team and ask them for an update. What are we paying for if we do not have an officially supported version available to us?
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.
