Oh, no need to pick up rpg maker mv. Lust doll plus is made in rpg maker mv, so the solutions that apply to that program should theoretically work for LD+. Glad you could get it running, but oof at the new problem.
One other possibility is to just play the browser version, though you'll have to be very careful about not clearing your cache (which is where your save would be contained) https://www.newgrounds.com/portal/view/732699
I usually do use the browser version, but I wanted to try to download it. One thing I notice that is different is that in the video I linked there are two files in the MacOS folder, but seeing as how this issue is limited to few macs, I would assume that isn't the problem, but I wouldn't put it out of the question, so perhaps it's the lack of a Launcher.dat file or something. But here is to hoping that I can find a solution to this new problem as well. Thank you for helping out!
