Double-clicking on a file in the Mac Finder will open it using the default app. But what if you want to change the default?
Over time you may install new apps on your Mac that you prefer using instead of others for certain kinds of files. If you find yourself using the Open with option regularly for a certain kind of file, it may be time to set a new default. This way you can simply double-click to use your program of choice, which is loads more convenient than using right-click menus each and every time.
How to change the default Mac app for specific file types
- Control click or right-click on a file that uses the file type you'd like to change the default for.
- Click on Get Info.
- Find the section labeled Open with: and choose the app you'd like to use as a the default from the dropdown.
- Click on the Change All... button.
- The Finder will ask you to confirm the change. Click the Continue button.
You're all set! Now any time you open a file with that extension, the Finder will automatically open it with the new app instead of the old one.
