In mac there is a way, where you get index of file and from there you can click on you project and go to you project's index file, but if you don't get then alway for any Mac/Windows or other any you can write you path in browser.
In most cases it is "localhost/dashboard/yourProjectName"
But In your case, as you said your project is inside htdocs, path will be "localhost/project1"
so easy is to type the path into browser.
