How to Set a Different Search Engine for Private Browsing in Safari on Mac

Many Mac users rely on Google for their daily web queries due to its personalised results, local maps integration, and contextual convenience. However, when opening a Private Browsing window to research confidential health topics, financial matters, or sensitive business projects, transmitting your search queries to a provider that logs search histories diminishes the benefits of private sessions. In macOS Sonoma and macOS Sequoia, Apple allows users to designate an independent search engine specifically for Private Browsing windows. Learning how to set a different search engine for Private Browsing in Safari on Mac enables you to maintain privacy-focused defaults (such as DuckDuckGo or Ecosia) without changing your standard browsing setup.

How Independent Private Search Works in macOS Safari

Prior to recent macOS updates, Safari enforced a single, global search engine that applied equally across all windows, tabs, and sessions. Under Apple’s upgraded Safari architecture:

  • Regular Windows: Continue using your primary default provider (such as Google, Bing, or Yahoo).
  • Private Windows: Automatically route queries entered into the Smart Search field through your chosen private provider (such as DuckDuckGo), which does not store IP addresses or track search terms across queries.
  • Seamless Transition: You never have to manually navigate to an alternative homepage or adjust preferences when switching back and forth between standard and private sessions.

How to Configure a Separate Private Browsing Search Engine in Safari

Setting up your preferred secondary provider takes only a moment in Safari Settings:

  1. Launch the Safari browser on your Mac running macOS Sonoma, macOS Sequoia, or later.
  2. Click on Safari in the menu bar at the top-left corner of the screen and choose Settings (or press Cmd + ,).
  3. In the Settings window, switch to the Search tab along the top toolbar.
  4. Notice the primary Search engine dropdown, which controls standard browsing windows.
  5. Directly beneath this, locate the option labeled Also use in Private Browsing.
  6. Uncheck the box next to Also use in Private Browsing to unlock the secondary search configuration.
  7. Click the new Private Browsing search engine dropdown that appears and select your preferred privacy-oriented engine, such as DuckDuckGo or Ecosia.
  8. Close the Settings window to immediately apply the changes.

Testing Your Private Browsing Search Configuration

To verify that your configuration is functioning correctly:

  1. Open a standard window in Safari and type a random query into the Smart Search field. Press Enter to verify it opens in your regular search provider (e.g., Google).
  2. Click File > New Private Window (or press Shift + Cmd + N).
  3. Notice the dark address bar indicating Private Browsing mode. Type a query into the address field and press Enter.
  4. Safari automatically routes the request through your private search engine (e.g., DuckDuckGo) without altering the behaviour of your regular open tabs.

Additional Privacy Enhancements for Safari Private Browsing

  • Advanced Tracking and Fingerprinting Protection: In Safari Settings > Advanced, ensure Use advanced tracking and fingerprinting protection is set to in private browsing or in all browsing to strip tracking parameters from URLs.
