Huge Noob - Whonix

Unfortunately it looks like Tails, which seems to be the more user friendly option, is not available for newer mac OS. I was specifically looking for Tails as it does not save history. I see that Whonix can work for mac OS and that it does save history unless told not to do so apparently?

I apologize if this is an annoying question but I'm only just getting into such fields and I'm not sure I completely understand how if Whonix saves your history, why it's even a viable option? Thanks in advance!
