i downloaded the elder scrolls arena on my macintosh , i don`t have the manual of the game , how can i answer the questions at the end of the dungeon ? can you please tell me the answers ?

Well, they are supposed to be riddles, requiring some clever thought. But if you're really stumped, you can find the answers http://www.uesp.net/wiki/Arena:Unofficial_FAQ#I_can.27t_figure_out_the_answer_to_some_riddle.

Edit: Oh, wait, if you're talking about the copy-protection questions at the end of the tutorial dungeon, you should have the manual, in a folder called "docs," where the game is installed.

thanks , i made it by searching the whole list on the internet . btw thank you very much

p.s. i did it on my mac , my copy did`t have it

Not sure how this particular software installs on Mac, but sometimes you have to look inside a mac app (Show Package Contents) to get to things like doc directories.
