Have you ever clicked on a PDF file on your Mac, only to have it open in an app you'd rather not use? Whether it’s dealing with an unfamiliar interface or simply preferring another app, you’re not alone in wanting to change the default application. The good news is, this process is straightforward and can greatly enhance your productivity. Here, you'll find a comprehensive guide on how to change the default app on Mac for PDFs, along with handy tips to make your experience on macOS even smoother. Let's dive in and take control of your file-opening preferences!

Understanding Default Applications on Mac

Before changing the default app for your PDFs, it’s essential to understand what default applications are and why they matter. Default applications are the programs that your operating system uses automatically to open certain file types. macOS assigns a default application to each file type based on its extension. For PDF files, this is often Preview, but it can be set to another app if you’ve downloaded alternatives like Adobe Acrobat, Skim, or PDF Expert.

Why You Might Want to Change Your Default PDF Viewer

There are several reasons one might consider changing the default PDF viewer on a Mac:

• Features: Some apps offer advanced features like editing, annotation, or form filling.
• User Interface: Preference for a different or more intuitive interface.
• Performance: Some applications may open quicker or handle large files better.
• Integration: Needing better integration with other tools or workflows.

Changing the Default PDF Viewer: Step-by-Step Guides

Method 1: Using Finder

1. Locate the PDF File:

   • Open Finder and navigate to a PDF file.

2. Get Info on the File:

   • Right-click on the file to reveal a dropdown menu.
   • Click on "Get Info". Alternatively, you can select the PDF and press Command + I.

3. Change the App in "Open With":

   • In the Info panel, locate the "Open With" section.
   • Click the dropdown menu and select your preferred app.

4. Set as Default for All PDFs:

   • Click the button that says "Change All..." to apply this change to all PDFs.
   • Confirm the change by clicking "Continue" when prompted.

Method 2: Via System Preferences

1. Open System Preferences:

   • Click on the Apple menu in the top-left corner of your screen.
   • Select System Preferences.

2. Navigate to "Extensions":

   • In the System Preferences window, find and click on Extensions.

3. Adjusting Defaults:

   • Though Extensions is more about enabling additional functionalities, some versions of macOS might allow switching default handlers here. If not, revert to Method 1.

Method 3: Third-Party Applications

Some third-party apps come with options to set themselves as the default viewer during installation or via their in-app settings. If you opt for this route, follow these steps:

1. Install the App:

   • Download and install your preferred PDF app from the Mac App Store or the developer's site.

2. Change Default Setting:

   • Upon installation, some apps may prompt you to become the default PDF handler. Accept this change if it suits your needs.
   • Alternatively, use the app’s settings to adjust the default options manually.
