My toddler son sometimes starts using my iMac and usually I don't mind. He likes to use Photo Booth, Skype, and watch some movies that are saved on the desktop. However, it has happened that he unintentionally has deleted files, renamed files, opened iPhoto and moved events around, etc.
Is there any way I can quickly enable a software or config that prevents the user from having "write" permission? I know I can create a separate account for him but I want to avoid the pain of logging out and such.
I wish there was a way to just hit a certain key combination to temporarily disable write access or something like?
Can anyone think of a solution for my problem?
Thanks!
