@lastraw, Have you look through http://codex.wordpress.org/Installing_WordPress_Locally_on_Your_Mac_With_MAMP or explored http://forum.mamp.info/index.php?c=1 ?
MAMP/MAMP Pro is a great development platform (I use MAMP Pro myself), but I think support for them may be a bit outside the charter of the Thematic community. Is there a charter?
Not trying to pick on you @lastraw, or anybody, but is there any plans or thoughts given to the possibly of creating a new forum which may be a little more directed or sub-divided? You know...like "Thematic Function Mods ", "Thematic Styling Mods", "Thematic T-Shirts", "Thematic Political Action Committee" etc. OK, maybe not the last one.
Yes, I know, a new thread would probably be in order.
@lastraw, MAMP/MAMP Pro is uber cool. You'll find the answer! Maybe this might help?
"If you go to MAMP Pro application's General tab, put the "Run Apache/MySQL server as user" to your OS X account name, not www/mysql."
