If you are having issues create a new topic in http://www.tonymacx86.com/unibeast/ with your UniBeast install logs. You can access the installation logs using the Console program in Utilities. In Console choose /var/log -> install.log. Copy all log entries starting with the line: "Install: "UniBeast Mac App Store"" And ending with: Displaying 'Install Failed' UI. Without this information I cannot determine what the failure is. Posting the installed failed message or that it doesn't work is useless and a waste of time. You MUST post the install.log to get assistance or to alert me to any bugs. Any posts with no log information may be deleted.
