How to change the default app on a Mac for a single file, or all files of the same type. I use this myself to change mp3 default app on mac because I prefer to open mp3 files in QuickTime instead of Apple Music, but you can change the default app for other files like PDF or image files like JPG, PNG and TIFF etc.
