Homestead 403 Error / Directory Permissions / Serving From Root

I'm currently developing a couple WordPress sites using Laravel's Homestead for local development.

I had things setup and working, but recently upgraded to a Mac workstation and can't remember exactly what I did to get things setup on my old machine.

I'm serving the sites from the root of the mapped folder instead of the /public/ directory, the default of Homestead.

When I try and load the site in the browser I get a 403 Permission error.

I remember on my old machine I had to edit some directory permissions for Homestead server to get things working, but can't remember exactly where or what.

Thanks for any help,
