Having trouble with Heimdall

[T3KH3D]

I was informed this might be the better subforum for this post...

Greetings!

I am trying to revert my Verizon Samsung Galaxy S5 G900V(B) back to Lollipop from Marshmallow. I don't have a PC but a Macbook Pro so I can't use ODIN. Instead I have downloaded Heimdall. I have downloaded several different versions of the Lollipop stock ROM but the Heimdall GUI is not recognizing them.

I *really* need to revert this back to Lollipop so I can use towelroot to get rid of all the crap Verizon bloatware that is eating my memory and making my phone unusable.

Any help would be so so so appreciated, thank you!
