Convert .PST File to .MBOX?

Hi,
I want to totally depart from Microsoft and PC and am wanting to convert the .PST folder from Outlook to .MBOX so that I can use Apple’s mail client as my default email.
has anyone else done this and how did they do it? I’ve got some extra folders with in Outlook so I’m hoping to copy all folders, contacts,…can anyone help me? I’ve seen some software’s advertise that are supposed to convert it but I don’t want to purchase something that’s not going to do the job. Thank you very much in advance! If that’s not clear please let me know.

I’ve used Emailchemy in the past with great success. Looks old, but works.

Thank you jaysee!

PST Converter Pro on the App Store will do the job. It’s $30 but worth it for me as I use it to convert a PST archive each year.
