Quick disclaimer, I've never done this sort of thing before. Whenever I use the make macinstaller command in terminal, it starts off by saying this:
xargs: illegal option -- -
usage: xargs [-0opt] [-E eofstr] [-I replstr [-R replacements]] [-J replstr]
[-L number] [-n number [-x]] [-P maxprocs] [-s size]
[utility [argument ...]]
And, I've searched both the home directory, and inside the ufoai folder, but I can't find the application bundle anywhere. Is it in some folder I haven't looked at, or did I do something horribly wrong?
