I hope I'm posting to the right area. My son has an iMac running OS9 I enjoy that he likes to explore all over the computer and open the control panel and do various things but he is only 4 (just barely) and he knows how to drag stuff to the trash and empty the trash. Is the a way to lock the system down so he can't throw things out or move files around. I want him to be able to play his games but I have to do a clean install just to get this iMac running correctly. The long and short of it is to not stifle his exploration but to be able to lock down sections and files. Thanks K.
