Thank you for taking the time to share your knowledge and answer questions.
It appears that I have successfully downloaded XAMPP. When I go to Preferences/Sharing or http://localhost I see a site that says:
"""If you can see this, it means that the installation of the Apache web server software on this system was successful. You may now add content to this directory and replace this """"
Now, HOW do I get to this mysterious directory?
I cannot find: XAMPP under the Applications folder?
Where is it?
Again, thank you!!!
