What is the primary function of the Photos app on macOS?

The primary function of the Photos app on macOS is to edit and organize images. This application allows users to import, store, and categorize their photos and videos in a user-friendly interface. Users can create albums, use advanced search features, and utilize various editing tools to enhance their images directly within the app. These editing tools include adjustments for exposure, color balance, cropping, and applying filters. The Photos app also supports features like syncing with iCloud, which allows users to access their photo library across different Apple devices.

Options that mention streaming videos, creating music playlists, or managing system preferences are not functions of the Photos app. Streaming videos is typically handled by apps designed specifically for media consumption, while music playlists are managed through the Music app. System preferences are adjusted within the System Settings application, thus distinguishing the specific role of the Photos app in managing personal photo and video collections.
