Apple is keen to guard these things in the new Mac operating system
PRIVACY IS IMPORTANT to Apple. In fact, the company considers it a human right. The macOS Sonoma operating system brings several privacy and security features to the Mac, all of which are designed to keep your data, browsing and personal information as private as possible.
1 Set private browsing search engine
In Safari, you can set up a different search engine to use when you’re in Private Browsing mode. This way, for example, you can use the ubiquitous Google for general browsing, but the more secure and private DuckDuckGo when you’re in a Private Browsing window. In the Safari app, click on Safari in the top bar and choose the Settings option. In the window that pops up, click the Search tab in the toolbar. You'll see your chosen search engine, and underneath, your Private Browsing search engine. If the latter says "Default", it’s the same as your regular search engine. Click on either menu to choose a search engine. You can choose different options for your search engine and your Private Browsing search engine if you wish.
2 Private browsing authentication
If you leave your Mac with a Private Browsing window open, and your Mac goes to sleep, your private tabs lock too. They can only then be seen by unlocking them with your password or Touch ID, independently of unlocking your Mac. A locked Private Browsing tab is completely blank. The toolbar and URL window aren’t shown, so it’s impossible to see where you’ve been on the web. All that’s visible is the field for entering your Mac’s password and instructions for using Touch ID. This feature is on by default, but if you wish to turn it off, in the Safari app, click on Safari in the top bar. Select Settings, and in the Privacy window, uncheck "Require Password/Touch ID to view locked tabs".
