I can't open Etterna

(on Mac btw) When I try to open the game, it just pops up with an error saying that I don’t have a noteskin. And even when I try to download and drag one in, it doesn’t allow me to. Is there something wrong?

searching for “stepmania no noteskins found” gives you the solution

the solution is also listed on every release build of the game https://github.com/etternagame/etterna/releases/tag/v0.70.4
