Install step 1: Couldn’t connect to the database.

Hi,

I'm having problems on step 1 of the installation. I'm doing the install on my local computer, a Mac running OS X 10.11.6 and using the built-in Apache. I've installed PHP 5.6 and MySQL 5.7 via Homebrew, and confirmed that both are working. I've created a database in MySQL for Grawlix. I did have to add the following line to the included .htaccess file in order to get past the 404 Forbidden error I was hitting when trying to load firstrun.php:

Options +FollowSymLinks

I've entered in the correct information for the host, database, user, and password on the firstrun.php Step 1 page, but when I click NEXT it just gives me the following error:

"Couldn’t connect to the database. Check your information and try again."

Also, I do get some PHP notices at the top of the page on load:

Notice: Undefined index: timezone in /Users/iadams/Sites/grawlix-1.2.0/firstrun.php on line 1167

Notice: Undefined index: user in /Users/iadams/Sites/grawlix-1.2.0/firstrun.php on line 1171

Notice: Undefined variable: output in /Users/iadams/Sites/grawlix-1.2.0/firstrun.php on line 310

Notice: Undefined variable: output in /Users/iadams/Sites/grawlix-1.2.0/firstrun.php on line 226

(From what I've read in the forums, though, those notices aren't showstoppers.)

Any ideas?
