I installed Net Barrier X in Jag, a window popped up saying there is a problem running Net Barrier do you want to "Fix and Use" and 2 other choices. I clicked the "Fix and Use." I went to the share panel and the Os X built in firewall does not work because the net barrier extension is running. So I searched for all the files containing barrier and deleted all of them. There were 3 that I couldn't delete because they were in use. I tried seeing in process viewer if any of the items in use were a process or if there was a net barrier process, No. I tried logging in as root in net info. I still can't delete them. So what I'm asking is, does anyone know how to uninstall Net Barrier and get the OS X firewall to work? Thanks A lot!
