I wanted to play a graphical Nethack for a change, and I found NethackCocoa in the Mac App Store. What bothers me is that it ignores my
~/.nethackrc - terminal Nethack works just fine with it. Snooping around in my system log I stumbled upon the following line:
sandboxd: () NetHack(56566) deny file-read-data /Users/tourn/.nethackrc
So I figure the problem is Lion sandbox-related. Since I heard nobody else complaining though I think it's still a problem with my personal setup.
I'm on OSX 10.7.5, if that's any help.
