Running Mage on OSX

Hey, I'm trying to run mage on OSX 10.8 with java 1.6 rev 43 but I keep running into PermGen Space errors when trying to start the client. Is anyone else finding this? Thanks.
PS. I've tried changing the options for MaxPermGen and PermGenSize to over 1048M so that's not the issue.
Thanks
