Sometimes you may have more than one application on your computer that can open the same type of document, for example on Windows you may have Adobe Reader and the built in Reader application that can open PDF files, and on Mac OS you may have Adobe Reader and Preview.
So, if you’d like to set which application opens a PDF file when you double click on it, then this is very easy to do. Just follow the steps below. You can then use this method for any type of file.
Once you’ve set these applications, they’ll open all files of that type in your preferred software.
Right click on the file, then click on Get Info and then use the Open with list to choose the application that you would like to use and click on the Change All button, as shown below.
Right click on the PDF file, then click on Properties on the menu that pops up. You can then change the application that opens PDFs by clicking on Change as shown in the picture below. This will change the application that opens PDF files.
