Hello, xXWeirdCoolCatXx here to show you how to make a Hamachi for Mac. I know Hamachi servers are kind of suckish, but it works, even if your router is incompatible with portforwarding. Lets get started!

Mac OSX
Yes we all know things on Mac OSX is hard since people do it on windows 99 percent of times, but heres a working tutorial.
1. First off is for Mac. First off, download Hamachi. Just google it and your ago.
2. Open up hamachi, at the OSX Menu Bar select Network, Create a network, Fill in the forms.
3. Ok after you clicked done, you can right click the network, properities, then you can disable the password if you like. Non-recommended!
4. Tell your friends your network!
QUICK TIP: REMEMBER YOU CAN CREATE MORE THEN 1 FOR LARGER SERVERS!
5. Create a folder anywhere called "Hamachi Server" or anything you wanna call it.
6. Download a build of CraftBukkit, Development: LEAST STABLE! DANGER! Beta: Kinda Stable, Still buggy! Recommended:Not 1.7.2 yet, but least buggy. And put the download into the Hamachi Server folder we just made.
7. open TextEdit/TextWrangler/Xcode, but we're gonna use TextEdit. Paste the code:
#!/bin/bash
cd "$( dirname "$0" )"
java -Xmx1600M -jar craftbukkit.jar -o true
Ok now heres the important stuff. -Xmx(Number)M indicates how much Megabites to run. -o indicates if online or not, -o false = cracked -o true = premium.
IMPORTANT: SAVE YOUR CODE AS RUNSERVER.COMMAND IN YOUR CRAFTBUKKIT FOLDER.
8. Open up Terminal, Its in your Dock or search it in Spotlight. Paste in chmod a+x  remember the space at the end, then drag in your RunServer.command and hit enter. If nothing looked like it happened, success! It just gives it permission to run.
9. open up RunServer.command, and you'll see files generating in your Hamachi Server folder. No need to fuss.
After it says "Done! Enter "help" or "?" for commands." you can type stop into the terminal and it will stop. After it says [Process Completed], close up terminal.
10. You should see  server.properities, Right click, "open with" then hit TextEdit. Most of it you can tinker with, but heres the important stuff:
11. Open Hamachi. Beside the power button, you should see a IP. You cant highlight it, so just hand-type it into the Server-IP: part of server.properities!
12. Start your server up and tell your friends your IP once they joined the Hamachi Network! It should work! Congratulations on making a Hamachi server! Give yourself a pat on the back!


TROUBLESHOOTING
If your open your server and it says **FAILED TO BIND PORT** Perhaps a server is already running on that port?
Then go into server.properities change your port to something else that is 5 numbers long. it should work. save, then open up RunServer.command again.
Hope this helped!
