Change which application opens a file on macOS
Unlike Windows, macOS decides which app should open a file using more than just the filename extension. The system looks at the file’s type and extension, and also uses a creator code that can tie a file to a specific program.
Why this matters
Because of that extra creator-code piece, switching the app associated with a file on a Mac can be less straightforward than on Windows. Adjusting these identifiers lets you redirect a file to a different application, but doing it manually can be confusing if you haven’t worked with creator codes before.
Using TypeShuffler to update the creator code
TypeShuffler simplifies changing the creator code so a different app will open a file. The basic workflow is simple: drop the file onto TypeShuffler’s icon, edit the creator code field to the desired value, and save the change. That updates which application macOS will use to open that file.
