You might have to right click it and select "Open With" and choose Terminal from your utilities folder; that shouldn't be happening, though, I'll make sure I have perms set right. I re-downloaded the script and opened it with Terminal the way you told me to, but Terminal just opened a blank Terminal window, identical to what happens when I just open Terminal by itself without the script. I've done this both with and without PZ running in the background. Any idea what might be the cause for this? If it helps out it any way, Terminal was not one of the recommended apps when I right-clicked and choose "Open With". I have also never had any mods or such installed. you could try it the same way as i did to get it running: download the script from Rathlord somewhere. open a terminal and cd to the directory where you downloaded the script to. If you downloaded it into your "Download" folder: cd ~/Downloads then i added the execute right to the script: chmod +x OSX_Server_Script.sh after that execute the script: ./OSX_Server_Script.sh Download OSX_Server_Script.sh to your Download folder Open Terminal App ( i use iterm2, the builtin Terminal is fine too) cd ~/Downloadschmod +x OSX_Server_Script.sh./OSX_Server_Script.sh
