Do you own a copy of Quake 3 for mac or pc..

Also the OX version of Quake 3 app should be in same folder as id1

I believe i had this problem once
It asks you so locate the folder with the Q3A files, right?
Or at least, it did the first time.

You should always point to the top Q3A directory. In this case, the same directory, the Q3A original application is in.

If it doesn't ask you anymore in which directory to look, then toss out your .q3a folder in your homedir and any prefs in homedir/Library/Preferences, which are from Q3A.
