After first installing 4.4 beta 5, i was having a problem seeing any sub directories on the PS3, but a quick rebuild fixed that.
The main issue i'm having now is that there's a Safari browser popping up behind the main login window. I've already stated this in a different post, but this should really be a spot for the MAC so others can list any issues they're having.
