The email application pre-installed on macOS is designed to manage electronic correspondence upon initial system startup. This software provides a user interface for composing, sending, receiving, and organizing messages without requiring the installation of third-party programs. For example, upon purchasing a new MacBook, the operating system includes this mail application ready for configuration with an email account.
Having a readily available email solution ensures immediate communication capabilities for users. Its presence streamlines the initial user experience by removing the need to search for and install alternative software. Historically, it has provided a consistent and fundamental communication tool deeply integrated within the operating system, undergoing iterative updates alongside macOS to maintain compatibility and security.
