The operating system determines which application opens a specific type of file. For instance, double-clicking a .jpg image might automatically launch Preview, while a .pdf document may open with Adobe Acrobat Reader. Customization of this behavior allows users to specify their preferred applications for handling various file types and protocols. This control ensures a consistent and efficient workflow.
Specifying the program used to open particular files enhances productivity by eliminating the need to manually select an application each time. It promotes a more seamless user experience and allows individuals to leverage specialized software tailored to their specific requirements. The capability to configure these settings provides greater flexibility and adaptability within the macOS environment. This level of control has been a consistent feature in successive iterations of the Mac operating system, reflecting Apple’s commitment to user customization.
