About Remote Desktop user mode

When a non-administrator user opens Remote Desktop to administer Remote Desktop client computers, Remote Desktop operates in what is known as user mode.

The administrator of the computer with Remote Desktop installed can select which features and tasks are available to non-administrator users. However, changing Remote Desktop admin settings is no substitute for setting proper access privileges in the Sharing pane of System Preferences on the client computer.

You can define exactly what operations non-administrators can perform on client computers.
