Check the browser requirement
Apple introduced Safari profiles in Safari 17. Confirm the installed Safari version before looking for the feature. A profile can be useful when you need a separate personal or work browsing context; it is not the same as selecting a different viewer profile inside a streaming service.
Create an identifiable context
Apple documents Safari’s Create Profile action or Settings, Profiles. Choose a name, symbol and colour that make the context recognisable. When first enabling profiles, the existing browsing context becomes the default Personal profile; the new context is additional rather than a fresh operating-system account.
Expect a separate website session
Apple says history, cookies and other website data are not shared between profiles. A site in the new context can therefore ask you to sign in again. Before entering credentials, verify the actual website address and intended service account. A second sign-in does not itself mean that a previous subscription disappeared or needs to be purchased again.
Check the shared features too
Apple identifies AutoFill, Passwords and several settings as shared, with bookmarks available across profiles even though favourites presentation can differ. Use the new profile for its documented separation, not as a security guarantee against another person using the Mac. Test the particular site session you meant to separate and preserve necessary account recovery information.
