Mac newbie here: LbF connects to LIVE not local site

The question of connecting to a live site appears often but with no clear answers. I’ve probably done something wrong in formatting the basic platform (VBox?) or renaming the domain or… Is there a step-by-step guide anywhere that says “Here is what to do after you’ve got everything ready to import into LbF”?

Alternatively, I am eager for any suggestions.

TIA,

Karen
