I recently installed Adobe Premier and now it wants to open all of my CSV files.
I try to change the default application to Numbers by using open with - but it only changes the application for that single file!
How can I change it so that ALL CSV files open with Numbers?

Instead of using 'Open With' go to 'Get Info' on the Get Info panel you will see there is the option to choose the default application to open the file and then click the 'Change All' button - this will update the default file handler for all CSV files (or any other kind of file you want to change!)
