Your Mac Browser Settings Explained

Understanding Safari Privacy Settings on Your Mac

Safari is the default web browser that comes with macOS, and it has several privacy controls built directly into its settings. These controls determine what information websites can collect about you while you browse. Privacy settings exist because websites often track your browsing habits, location, and personal information to show you targeted advertisements or sell data to third parties.

When you open Safari on your Mac and go to the Settings menu, you'll find a Privacy tab. Within this section, you can control whether websites can access your location data. If you disable location access, websites cannot determine your physical location even if they ask permission. This setting is separate for each website, meaning you can allow location access for a mapping service but deny it for a news website.

Safari also includes controls for cookies and website data. Cookies are small files that websites store on your computer to remember information about you, such as your login status or shopping cart contents. The Privacy settings let you choose whether to accept cookies from all websites, only from websites you visit directly, or not at all. You can also set Safari to remove cookies automatically when you close the browser or keep them indefinitely.

Another important privacy feature is Intelligent Tracking Prevention (ITP). This technology automatically blocks many types of tracking cookies that follow you across websites. When ITP is enabled, Safari limits the ability of advertisers to track your browsing across different sites. You can view which trackers Safari has blocked by clicking the privacy icon in the address bar of any website.

Safari also allows you to prevent cross-site tracking, which stops websites from sharing information about your browsing activity with other websites. This setting is typically found under the Privacy tab and can significantly reduce how much data is collected about your online behavior across different sites.

Practical takeaway: Visit Safari Settings > Privacy and review your cookie policy and tracking prevention settings. Consider enabling "Prevent cross-site tracking" and setting cookies to be removed "when you close the website" if you want stronger privacy protections while browsing.

Managing Cookies and Website Data Storage

Cookies serve different purposes depending on how websites use them. Session cookies are temporary and only exist while you're using a website. These help websites remember items in your shopping cart or keep you logged in during a single visit. Persistent cookies remain on your computer after you close the browser and can last for days, months, or even years. Websites use persistent cookies to remember your preferences or recognize you when you return.

Third-party cookies are created by companies other than the website you're visiting, usually advertising networks. These cookies track your behavior across many different websites to build a profile of your interests. This is how you might see ads for a product you searched for on one website appearing on a completely different website. First-party cookies, by contrast, are created only by the website you're directly visiting.

In Safari's Privacy settings, you have three options for cookie handling. The first option accepts cookies and website data from all websites without restriction. This provides the most seamless browsing experience but also allows the most tracking. The second option accepts cookies only from websites you directly visit, blocking third-party cookies that tracking networks try to set. The third option rejects all cookies entirely, which provides maximum privacy but may break functionality on some websites that legitimately rely on cookies.

Safari also stores website data beyond just cookies. This includes cached files, local storage, and IndexedDB data that websites create to store information on your computer. When you clear your browsing history in Safari, you have the option to also remove "all website data." This will delete cached images and files that websites have stored, which can help maintain privacy but may make websites load more slowly on your next visit since they'll need to re-download these files.

You can also manage data on a per-website basis. In Safari Settings under the Privacy tab, there's an option to see which websites have stored data on your Mac. You can select specific websites and remove their stored data without affecting other sites. This is useful if you want to clear data from a website you don't visit regularly while keeping data from sites you use frequently.

Practical takeaway: If you browse frequently and value privacy, select the option to accept cookies only from websites you directly visit. This blocks most tracking while allowing legitimate website functionality. Once monthly, go to Settings > Privacy and clear website data for sites you don't visit regularly.

Configuring Search Engine and Homepage Preferences

When you open a new Safari window or click the home button, you see your homepage. By default, Apple's Safari shows a curated start page with news stories and suggested websites. However, you can change this to show a blank page, a specific website, or a custom webpage. Your homepage setting doesn't affect your privacy directly, but it determines what loads when you start browsing.

More importantly, Safari's search settings determine which search engine processes your search queries. Apple uses Google as Safari's default search engine on most Macs. This means when you type search terms in the Safari address bar, your query goes to Google's servers. Other available search engines include DuckDuckGo, Bing, and Yahoo. Each search engine has different privacy practices. For example, DuckDuckGo explicitly states it doesn't track your searches, while Google uses your search history to build a profile of your interests for advertising purposes.

To change your search engine, go to Safari Settings and find the Search tab. There's a dropdown menu labeled "Search engine" where you can select from several options. Some search engines like DuckDuckGo market themselves as privacy-focused because they don't create persistent profiles of your searches. However, your internet service provider can still see that you're using DuckDuckGo, even if Google can't see your specific search terms.

Safari also has a feature called "Search engine suggestions" which, when enabled, shows suggested search terms as you type in the search bar. These suggestions come from your chosen search engine's servers. If you're using Google, enabling suggestions means Google receives the partial text you're typing even if you don't complete the search. Disabling this feature prevents your partial searches from being sent to any search engine.

The address bar behavior is another setting worth understanding. Safari can be set to show search suggestions, website suggestions based on your browsing history, or both. Website suggestions show pages you've previously visited that match what you're typing. This is purely local to your computer, but search suggestions are sent to your search engine provider's servers, even if you never press Enter.

Practical takeaway: If privacy is important to you, visit Safari Settings > Search and disable "Search engine suggestions." Consider changing your search engine to DuckDuckGo if you want your searches to be less connected to an advertising profile, though be aware your ISP may still see you're searching.

Controlling Extension Permissions and Website Access

Safari extensions are small programs that add functionality to your browser, such as password managers, ad blockers, or translation tools. Extensions can access information about your browsing activity and modify websites you visit. Because of this power, it's important to understand what permissions each extension has and whether you trust the extension developer.

When you install an extension from the Safari App Store, Apple has reviewed it for security. However, this doesn't mean the extension respects your privacy. Many useful extensions collect data about your browsing habits as a business model. For example, some coupon extensions track which websites you visit to determine when to show you discount codes. You should only install extensions you actively need and understand the purpose of.

In Safari Settings, you'll find an Extensions tab that shows all installed extensions. For each extension, you can grant or restrict its permissions. Common permissions include access to website content, your browsing history, and tabs you have open. You can also set an extension to "Always Ask" before allowing access, so you approve its actions on a case-by-case basis. Some extensions require broad access to function, while others need access only to specific websites.

You can configure whether an extension runs on all websites or only specific ones. For instance, if you have a grammar-checking extension, you might set it to run only on Gmail and documents you write, not on every website you visit. This reduces the amount of information the extension can collect about your browsing. An extension that only runs on specific sites also has less opportunity to track your behavior across the web.

Safari also shows you when extensions are being used. If you notice an extension is active on websites where it shouldn't be, you can remove it or adjust its settings. The privacy icon in Safari's address bar can sometimes show when extensions are running on a particular page. It's worth periodically reviewing your extensions and removing ones you no longer use
