Making Preview the default app for viewing PDFs and images on your Mac can significantly streamline your workflow and enhance your productivity. Here’s a simple, step-by-step guide to help you set Preview as your default application.
Why Use Preview as the Default App?
Preview is a powerful tool that comes with macOS, offering features such as annotating documents, combining PDFs, and editing images. It is user-friendly and integrates seamlessly with other macOS applications.
Method 1: Using Finder’s ‘Get Info’ Option
This is the most straightforward method to set Preview as the default app.
- Right-click on the file you wish to open with Preview by default (e.g., a PDF or an image file).
- Select ‘Get Info’ from the context menu (or select the file and press Command + I).
- Under the ‘Open with:’ section, click the dropdown menu and select Preview from the list of applications.
- Click the ‘Change All…’ button below the dropdown menu to set Preview as the default for all files of that type.
- Confirm the change when prompted by clicking ‘Continue’.
Method 2: Adjusting Default Apps via the Open With Menu
This method is another easy way to set the default app.
- Right-click on a file of the type you want to open with Preview.
- Hover over the ‘Open With’ submenu.
- Choose Preview from the list of available applications. If Preview is not listed, scroll down and select ‘Other…’, then navigate to Preview in the Applications folder.
- While holding down the Option key, notice that the ‘Open’ button changes to ‘Always Open With’. Click it.
- Confirm that future files of this type now open with Preview by double-clicking another file of the same type.
Method 3: Managing Defaults with System Preferences
Although this method is more about web browser settings, it can sometimes affect how PDFs are handled.
- Click on the Apple menu, and select ‘System Preferences’.
- Open ‘General’ settings.
- Look for the ‘Default web browser’ menu. Although this primarily changes the web browser, it can sometimes affect how PDFs, linked from web pages, are handled.
- If Preview is available as an option in the dropdown, select it. Otherwise, use Method 1 for file types that aren’t web-related.
Method 5: Using Terminal Commands
This method is for advanced users who are comfortable with the command-line interface.
- Open the Terminal application (found in Applications > Utilities folder).
- Type
duti -s com.apple.Preview .pdf all
to set Preview as the default for PDFs, replacing ‘.pdf’ with the file extension of your choice. - Press the Return key to execute the command.
- Note: The Duti tool may need to be installed first.
