Does anyone here have experience installing alfresco-one-ear-distribution-5.1.2 on OSX. I've tried, but I'm getting this error in the Weblogic Admin console when I try to start the Alfresco Server. "For server AlfrescoServer, the Node Manager associated with machine Alfresco Machine is not reachable." I also get this error when ran the node manager, but it did start. "Message icon - Warning All of the servers selected are currently in a state which is incompatible with this operation or are not associated with a running Node Manager or you are not authorized to perform the action requested. No action will be performed."
