I did some minor searching and wasn't able to find the answer easily. pardon the newbie question.
I tried grabbing Marathon .dmg files and all the new content based off Aleph One, but nothing runs. Assuming the official build of Aleph One doesn't run under macOS 10.13.6, which is what I'm running. Is there a way to make Aleph One run in 10.13 or is there a recent build that I can try? Would that also work for the original Marathon trilogy releases as well? Thanks in advance.
