As you type a query or website address into Safari’s Smart Search field on macOS, the browser analyses your input and anticipates the most likely destination. Under its default configuration, Safari designates this top recommendation as the “Top Hit” and silently preloads the webpage in the background before you even press the Return key. While this predictive mechanism speeds up navigation when you intended to visit that exact site, it introduces significant downsides.
Preloading fetches web assets, scripts, and trackers over your network for pages you may never open. On metered Wi-Fi connections, mobile hotspots, or limited data plans, this background traffic wastes bandwidth. Furthermore, background preloading can trigger server-side sessions, execute tracking cookies, and cause unnecessary CPU overhead on MacBook batteries.
Step 1: Open Safari Settings
Disabling background webpage preloading is configured directly within Safari’s global search preferences:
- Open Safari on your Mac.
- Click Safari in the menu bar at the top-left corner of the screen.
- Select Settings… (or Preferences… on earlier macOS versions), or press the keyboard shortcut:
Command + ,Step 2: Disable Preload Top Hit in the Background
With the Settings window open, adjust the search engine behavioural toggles:
- Click the Search tab represented by the magnifying glass icon along the top toolbar.
- Locate the Smart Search field section.
- Uncheck the box labelled Preload Top Hit in the background.
Safari will immediately cease initiating background TCP connections and fetching resources for anticipated results while you type.
Step 3: Optional Search Privacy Toggles
While inside the Search tab, you may want to refine additional predictive features that transmit keystrokes or consume network resources:
- Include search engine suggestions: Unchecking this prevents Safari from sending every character you type to Google or your default search provider before pressing Enter.
- Include Safari Suggestions: Unchecking this disables Apple’s algorithmic suggestions, news headlines, and Wikipedia cards from appearing under the Smart Search field.
- Quick Website Search: Keep this enabled if you enjoy typing a domain name like “wiki” to search directly within a site without loading its home page first.
Close the Settings dialogue. Your changes take effect immediately without requiring a browser restart, giving you full control over when web requests are dispatched from your Mac.
