Hey guys I've been pouring over the Internet and can't find anything to help me with a problem I have. I have a brand new 27" iMac running 10.7.4 Lion. I have the latest version of XQuartz as well as the latest version of PSS. I've uninstalled and reinstalled the software several times and still nothing happens. PSS isn't opening and it isn't opening XQuartz. Any ideas guys would be a huge help. Thanks in advance.
