Safari Profiles separate browsing contexts on one Mac without requiring a different macOS user account. They are useful when work and personal websites use different logins, histories, extensions, and tab sets.
Create and enter a profile
Safari Profiles require Safari 17 or later. In Safari, choose Safari > Create Profile, or open Safari > Settings > Profiles. Start using profiles, then give the new profile a name, symbol, color, and favorites folder. Your existing browsing context becomes the default Personal profile when you create the first additional profile.
Open a new window for the intended profile before signing in. Keep a visible profile clue in the window and avoid moving sensitive tabs between profiles without checking the destination identity.
Know what is actually separated
Apple states that browsing history, cookies, and other website data are not shared between profiles. Tab Groups are also separate. Extensions are installed for Safari as a whole but can be enabled or disabled per profile; new profiles start with extensions off. Start-page and new-window settings are profile-specific.
Bookmarks remain available through the Bookmarks menu or sidebar. Favorites bars can be shared when profiles use the same favorites folder. Profiles can sync through iCloud when compatible devices use the same Apple Account and Safari is enabled in iCloud.
Treat profiles as browser identity
A profile separates browser data, not all files, apps, permissions, or macOS windows. Wallo may organize a Safari window with a project, but it does not enforce the active profile or isolate website accounts. Confirm the profile in Safari whenever identity matters.
