Description of issue

VirtualBox 7.1 was just released and it's cask has been updated but... it still has hard requirement on x86 (https://github.com/Homebrew/homebrew-cask/blob/HEAD/Casks/v/virtualbox.rb#L25) even though this version does support arm64.

I see that virtualbox@beta cask handles this: https://github.com/Homebrew/homebrew-cask/blob/HEAD/Casks/v/[email protected]

Would using beta cask as a template but with updated versions/hashes be ok or that would be too much of a difference?

Relevant casks

virtualbox, virtualbox@beta

Cask was updated around time of discussion post so may be fixed already: Homebrew/homebrew-cask#185148
