Specifying the application a computer uses automatically when a file is accessed is a common requirement. This process, achievable on macOS, allows users to customize their workflow and ensure files are opened with their preferred software. For instance, a user might prefer using Adobe Photoshop to open all JPEG images instead of the default Preview application.
Modifying these associations offers substantial advantages. It streamlines the user experience by eliminating the need to manually select an application each time a file is opened. Historically, operating systems have offered methods to control these file associations, recognizing the importance of user control over their digital environment. This capability enhances productivity and allows individuals to tailor their systems to suit their specific needs and software preferences.
