Hi, i just bought a new macbook pro 2.53Ghz (and LOVE it). when i transferred my users via ethernet from my old mac to the new mac, eerything worked, except that the finder kept asking me all the tim to identify myself (for every copy, delete etc. action). that was really annoying, so i clicked on the Macintosh HD symbol, and changed (including all subfolders) the user rights to "everyone read and write"... and now i am afraid that that might have consequences i cannot foresee.. what do you think????
