This is on MAMP and Mac OS X 10.7.
I turned on every App (save SEO) to try the distro and the install stalls with the first attached error.
Then discovered Mac OS Lion, MAMP , localhost / Unable to install apps via ftp and Document different ways to install and performed the chmod -R 777 sites.
Erased the db, deleted settings.php and started over.
Now it stalls with the second attached error.
Any support would be appreciated.
