Turn Your Mac into a Hotspot

I learned something new today!  Wahoo!  Those days are the BEST and to boot it was within the first 30 minutes of the day- Thank you Mr. P.  We have a internet signal in the school that we cannot figure out where it is coming from.  Our tech director had a hunch that someone had turned one of the iMacs into a hotspot.  What?!?!?!? Shut the front door!  I had NO IDEA that it was possible!  Oh course, I go to Google and check it out and found an awesome tutorial from MacYourself and it worked.  The tutorial is only, you know 3 years old but hey whatever!  So check the tutorial out and turn your standard internet connection wireless.  :-D  Enjoy!
