hi, say if ive got a folder on my leopard macbook. when i double click it.... is it possible to put some type of sercurity on it? where it would ask me for my admin password? i tried 'get info' and putting lock icon on,....but thats just settings for writing to the folder....... can i do this? just so i can keep safe some private info secure and not accessible for other users on my mac. i dont think i can store files in keychain thing....... thanks.
