Cant view anything.

El Capitan 10.11.1 running 5.0.12

I've changed the resolution to something I cant see. i would appreciate if someone could help me with either

The directory to delete all files for a clean install

or

screen shots with keys to blindly reset the settings.

Use finder and go to this location: ~/Library/Preferences/StepMania 5

Inside open up the preference.ini file with textedit.

These are what my default values are on my mac from a fresh install:

DisplayAspectRatio=1.777778
DisplayColorDepth=32
DisplayHeight=540
DisplayId=
DisplayWidth=960
