WaffleTaco's Ret Pally M+ Macro (10.2)

I run this fast as possible. Idk why but whenever i run macros from here any slower my dps drops off

Hello everyone. I want to learn what is version 1 and version 2. What should i do with this ? Don’t I just have to press the icon that comes with GSE? What else should i do ? I am new with this sorry if i disturb you. Kind regards.
