For anyone interested, this seems to run under Wine using Winebottler to make it into an app. Even better it has both Classic and Designers Edition modes! I successfully exported a generic map as a PNG and measured a new in Photoshop and it looks to be correct.
Thank you @L0ki once again, I think I can consider my problem solved for now. Maybe someday I can get more fancy and customized but this will certainly hold me over!
I am a happy boy!
