vbox 6.1 on catalina 10.15 solution

[bingalls]

I had vbox 6.0 (ubuntu 20.04 guest) working on catalina 10.15. Then I ran a Homebrew Cask upgrade, which broke it.
I tried other solutions that did not work for me. I could not install a fresh ubuntu iso; nothing shows in log. Be sure to back up your existing virtual machine, and understand these steps before proceeding at your own risk.
Finally, I did

Code: Select all

brew cask uninstall virtualbox virtualbox-extension-pack

# if you also use extension-pack

Code: Select all

brew cask install virtualbox-beta

If you don't currently use Homebrew Cask, you can install and overwrite your existing Virtual


The new virtualbox-beta prompts you to permit sound in OSX security settings. Once you allow sound, and finish your install, you can uninstall the beta, then re-install virtualbox.

Thanks a lot!
This has worked for me
