How To Seal Safari Private Tabs In macOS Sonoma and iOS 17?

To seal Safari Private Tabs in macOS Sonoma and ensure they remain locked while unattended, follow these steps based on the provided resources:

For macOS Sonoma:

1. Open Safari.
2. Enable "Private Browsing" if it isn't already active. Click on 'File' > 'New Private Window'.
3. Once in Private Browsing mode, Safari automatically locks private browsing windows when you're not using them, according to the WWDC 2023 transcript. No manual action is required to seal individual tabs within Private Browsing.

Please note that the search results did not explicitly mention a method to manually seal each private tab individually. However, the automatic locking behavior should provide the desired level of protection during periods of inactivity.

For iOS 17:

1. Ensure you're running iOS 17 on your device.
2. Launch Safari.
3. Enter Private Browsing mode by tapping on 'Pages' icon (two squares), then selecting 'Private' at the bottom of the page list.
4. Similar to macOS Sonoma, Safari on iOS 17 automatically blocks known trackers from loading on pages and removes tracking from URLs as you browse in Private Browsing, per the WWDC 2023 transcript. Again, there doesn't seem to be a specific option to manually seal individual private tabs.

Remember that once you exit Private Browsing mode, your browsing activity won't be protected until you enter Private Browsing again.
