I finally figured out how to get ZC to run on my mac after 2 hours of reading, for anyone having this issue, you have to right click classic or editor, show contents/maco os/exec file. I started to make a custom quest, it will not load even though the destination folder is correct and the custom file is in correct folder, I can navigate to it, but it fails to load (unable to load file)It will not load built in quests either. Also when I try to play the built in quest (quest 1) when I get to register name screen, it is completely blank, i can hear my actions (bing sound) but it's blank. I am using latest mac version, 2.50 i believe, and I am running OS X High Sierra. Help please?
