$100.00 to package my game?

I’m finished with a project and I need to package it for a Mac. I’m following this tutorial on youtube on how to do so when the person says you have to pay $100.00 a year to Mac/ itunes to develop your game. Is this the only way to package your game for a Mac?

In order to release a game to the App Store or the Mac App Store you need to have to enroll to Apple’s Developer Program, which indeed costs 100USD / year
