The process of designating a specific application for opening Portable Document Format (PDF) files on macOS involves reassigning the system’s default file handler. This adjustment ensures that when a PDF document is accessed, the chosen application launches automatically to display its content. For instance, one might prefer using Adobe Acrobat Reader over the built-in Preview application.
Modifying the assigned application offers several advantages. It allows users to leverage the specific features and functionalities of their preferred software, such as advanced editing capabilities or unique annotation tools. Furthermore, it creates a more streamlined workflow by eliminating the need to manually select an application each time a PDF is opened. Historically, macOS has provided mechanisms for user customization, reflecting the operating system’s commitment to individual preferences and productivity.
