Tiger Tips: Kid Safe Account
There's a cool tip over at MacFixIt Mac OS X Hints (oops!) today, pointing out one of the cool new features of Tiger. With the new Parental Controls—which you can find by launching System Preferences, choosing the Accounts control panel, and then clicking on the Parental Controls tab—you can set up an account with no password, so that your kid(s) can simply click on a picture to log in, and then enable Simple Finder and set specifically the different programs your child can access.
A side effect of all this is that SSH is automatically turned off for the account, so there is no worry about anyone hacking in to the password-less account. Pretty cool.
