What does the Disk Utility app do in macOS?

The Disk Utility app in macOS is primarily designed to manage disks and storage devices. This includes tasks such as formatting drives, partitioning disks, and verifying or repairing file systems. Users can also use Disk Utility to create disk images and manage both internal and external drives. By allowing access to the structure and integrity of the storage devices, Disk Utility plays a critical role in maintaining the overall health of the system’s storage environment.

While optimizing system performance, enhancing security settings, or cleaning up temporary files can be relevant to overall system maintenance, they are not the primary functions of the Disk Utility app. Its focus on disk management makes it an essential tool for users who need to handle various disk operations effectively.
