Objective:

• Open CSV files in Excel, instead of Chapters
• Open CSV files in Excel, instead of Numbers

Environment:

• Mac

Additional Information:

• Before step 1, please ensure you're right clicking the file while it's in view in the Finder, not your list of Downloads in your web browser

Procedure:

1. Right-click on an Excel File (.xlsx, .xls, .csv, etc)
2. Click on Get Info in the pop-up.
3. Click Open With if the section isn't already expanded.
4. Click the dropdown and choose Microsoft Excel
5. Click Change All...
6. Click Continue when the Finder asks you if you're sure.

 

Now any time you open a file with that extension, the Finder will automatically open it with the app you've selected.
