If you can’t remove a profile, your Mac may be a managed computer. Contact a system administrator in the school or institution that provided you with the computer for more information. Some profiles can only be removed by a system administrator of your Mac.
Important: Some profiles may have a time restriction that only allows them to be installed within a specific period of time. Be sure to install the profile within the specified time limit.
Configuration profiles are files that standardize settings for Mac computers, iPhone and iPad, and Apple TV. If you have a system administrator, you may be asked to install a configuration profile to access your network, email, VPN, and other services.
If you’re a network administrator and need information about setting up managed computers and installing enrollment profiles, see the Deployment Reference for Mac.
If you’re a Mac app developer looking for information about provisioning profiles, see Create a development provisioning profile.
