abc import

I'm trying to convert an abc file into sheet music. I found an answer to this question that said “Go to Plugins > Plugins manager* Check ABC import on the list on the left and press OK”. I did this. It next said Go to Plugins > ABC import and copy paste your ABC code or load your ABC file. I cannot do this because when I go to plugins all I see are 2 links - 1 for plugins manager and 1 for plugins creator. I don't see "Plugins > ABC import" even after restarting the app. I am on a Mac using Sierra. I hope someone can tell me how to do this.
