How to get something like AHK working on MAC OS?

Hello there guys, just found my way back to wow after a 9 years break.
However i am not getting the flow like i should when playing due some movement problems with my fingers that happened due to hard labor.
and i stumbled upon this page when googling, i found some old threads here on the forum for setting up keyboard maestro for mac os, but i cant really get it to work since my computer skills arent that great.
Maybe someone of you guys can be a nice soul and help me set it something up like AHK on mac so i can enjoy the game fully?<3

thank you so much for the help.
