I'll see what I can do, though I wouldn't get my hope up to high for this game given how many macs it DOES seem to work for since I cant test myself: do you get any sorts of errors or reports or anything?
Yes, it just says, "The application “Build” can’t be opened."
The program somehow doesn't have the executable bit set. I think later OSX versions do this to unsigned apps but not sure.
`chmod +x ~/Downloads/Build.app/Contents/MacOS/PerilousWilde`
Then you can right-click -> Open to bypass the other "this app can't be opened" wall.
