OK, first of all, create a new folder. It will contain your server. Download your preferred version of CraftBukkit and move it to the folder. To start-up your server, you need to create a start-up script. Open TextEdit and paste the following: #!/bin/bash
cd "$( dirname "$0" )"
java -Xmx1024M -jar craftbukkit.jar -o true Save it in your folder as "server_start.command" Open up Terminal and type in "chmod a+x". Drag "server_start.command" into Terminal and press return. Click it to start your server and create the necessary files. That is how you create a server, as for allowing players to connect to it, you need to port forward. Go to "System Preferences", click "Network", and under "Status" should be your internal IP. Type it into your browser. From here, look up port forwarding instructions for your individual router brand. If you have any more questions, just ask!
