Every document or file you save on your Mac is associated with a particular application, so when you try to open it, it always opens with that app, not another app, when you double-click that file’s icon in the Finder. However, you can change the default app that opens a file. For example, so that presentations made with PowerPoint are always opened with Keynote. Let’s figure out how to do it. Change the default app you use to open a file Sometimes, you may want an app to open certain file types by default. For example, use VLC to open all.avi files instead of QuickTime, which will not play them for you.
3 - CMD click or right click the application that is set as the default app for the specific filetype, then select show package contents. 4 - Look for the icns file that the application is designating as the icon for the specific file type, it will probably be in a folder called Resources.
Or as I said before, open all the presentations you receive or download in Keynote, and forget about PowerPoint. In the Finder window, or on the desktop, right-click the file whose default startup application you want to change. From the context menu, select Open with → Other A new window will appear for you to select an app to open the selected file with. In our example, we are going to select Keynote, even though, as you can see in the image above, it already appears in the conceptual menu because I recently used it for this type of file. Find and select the app you want to use (Keynote, in this case). Check the box “Always open with this application”.
Press “Open”. The selected file will be opened with the app you have indicated, but the most important thing is that whenever you want to open this type of macOS file it will be opened by default with the application you have just indicated.
OS X ships with some great software. There’s iPhoto, iMovie, Pages, Keynote, and Preview that allow you to watch movies, view pictures, edit documents etc.
Apple’s design is for you to use your Mac immediately after you start it up for the first time. However, once you get familiar with your Mac, you’ll realize that there may be some other apps better suited to your needs. For example, iTunes is the default app for playing music, but you might want to use Vox or VLC. If that’s the case, you may be tired of right-clicking the file every time and selecting the alternative program to open it up. The following are two methods to change the default app in Mac OSX. Changing the Default App for That Specific File Only If you want to change the app that the file in question will open with, follow the directions below: 1.
Locate the file whose default app you want to change. Right-click (Alt-Click) the file. Press the “Alt” key on your keyboard. This should lead to “Open With” and change to “Always Open Up” as shown below: 3. Choose the app you want to use to open the file.

This will lead OSX to change the app for that specific file only. However, if you want to change the default app for all files of that same type, then follow the directions below: Change the Default App for All File Types 1.
Locate the file and right-click (Alt click) on the icon. Click on “Get Info.” 2. Click on the “Open with” tab. The Open with section shows the current app that this file type uses, and clicking on it reveals a drop-down menu that hosts the different application types you can choose. Click on it to reveal the drop-down menu. Select the application you want to use to open the file type. If your application is not in this list, select “Other” at the bottom of the list to browse through all your applications on your Mac. Once you’ve selected your application, click on “Change All” for all the changes to come into effect.
Select “Continue” on the pop-up menu that appears.
