The characteristic of a Guest account in macOS is that it provides limited access with no home folder. This type of account is designed for temporary use and allows a user to log in without requiring a permanent user account.

When a Guest account is used, it offers users the ability to access the system without the risk of exposing sensitive data or making permanent changes, since it lacks a home directory where personal files and settings would normally be stored. As a result, any changes made during the guest session will not be saved once the user logs out, maintaining the integrity of the system for future users.

The other options describe functionalities that do not align with the purpose of a Guest account. For instance, having unlimited access to system resources would compromise system security, and being primarily used for file sharing does not reflect the intended use of a Guest account, which is focused on providing limited, temporary access. Additionally, the Guest account does not have administrative privileges, which further ensures security by restricting the ability to make significant changes to system settings or configurations.
