When I upgraded to Snow Leopard, the permalinks (clean URL’s) on my local WordPress setup stopped working.

Instead of getting:

http://localhost/my-nice-permalink/

I would get:

http://localhost/?p=555

I was too busy then and couldn’t care less so I left it alone. Now I’m working on my blogs again and it sucks not to have permalinks working. So I did a little Google search and it turns out it wasn’t rocket science to have this turned on.

So now I’m going to show you how to enable mod_rewrite on Snow Leopard.

1. Open /etc/apache2/users/<username>.conf

replace <username> with your Mac username

2. Then change this:

<Directory "/Users/<username>/Sites/">
    Options Indexes MultiViews
    AllowOverride None
    Order allow,deny
    Allow from all
</Directory>

to this:

<Directory "/Users/<username>/Sites/">
    Options Indexes MultiViews FollowSymlinks
    AllowOverride All
    Order allow,deny
    Allow from all
</Directory>

3. Restart Apache under System Preferences » Sharing » Web Sharing

And you’re good to go. mod_rewrite is now enabled and your permalinks will work.
