Hi, I am new to wordpress too and am having similar problems. I followed the steps 1 up to 4. I went into the “wp-config-sample.php” using textwrangler.app and changed the info like it said in step 4.
database name: wordpress
database host/server: localhost
database user: root
database password: root
It than says “Once that’s complete, enter a blog name and email address, and you’re ready to use WordPress on your Mac.” Where do I do that? I still don’t know how to open the wordpress.app, because I don’t have one.
Any help would be appreciated, thank you.
