How to Remove a Mac From a Domain

By Bennett Gavrish

The Mac OS X operating system includes a tool called Directory Utility that lets administrators add Apple computers to domain networks. By putting Macs onto the same domain, you can control group authentication and file sharing. If you no longer want to use your Mac with a specific domain, an administrator can log on to the computer and remove it from the domain using Directory Utility.
