OS X Mountain Lion: Set limits on instant messaging
You can use parental controls to limit and monitor the people that a user communicates with using Messages. When you set Messages limits for a user, the user can chat only with people whose AIM addresses, including me.com and Mac.com, you approve. The user can’t exchange messages with Jabber, Google Talk, Yahoo!, or Bonjour addresses.
To restrict the user’s instant messages, you must first turn on parental controls for the user.
- Choose Apple menu > System Preferences, and then click Parental Controls.
- If the lock is locked, click it and enter an administrator name and password.
- Select the user you want to control, click People, and then select Limit Messages.
- To add an allowed Messages contact, click Add (+), and then do one of the following:
Enter an approved person’s name, and then in the Allowed Accounts field, choose AIM from the pop-up menu and enter a me.com, Mac.com, or other AIM address.
To add another address for this person, click Add (+) to the right of the address you entered.
To remove an address for this person, click Delete (–) to the right of the address you want to remove.
To add this person to your Contacts app, select “Add person to my address book.”
To select an approved person from the Contacts app, click the triangle to the right of the “Last name” field. Next click the rightmost column heading and choose Instant Message from the pop-up menu. Then select the approved contact’s address in the list and click Add.
To find a contact in the list, enter all or part of the contact’s name or address in the search field.
- To remove a person from the approved list, select the name, and then click Delete (-).
