Chrome多配置文件跨Mac同步、Safari适配及替代方案咨询

Hey there! Let me share practical, tried-and-tested answers to your two questions based on my day-to-day experience with macOS browsers:

You’re spot-on—Safari doesn’t have a native "profiles" feature like Chrome, but there are two solid workarounds depending on how much isolation you need:

• System-level user accounts (most isolated option)
  Create separate macOS user accounts via System Settings → Users & Groups for each person. Each system user gets their own fully isolated Safari environment: bookmarks, saved passwords, browsing history, and even installed extensions are completely separated. You’ll need to log out and back in to switch users, but this is the closest you’ll get to Chrome’s profile-level isolation.

• Tag Groups + iCloud Keychain switching (less friction, mild isolation)
  If switching system accounts feels too clunky, create dedicated Safari Tag Groups for each user. Then head to System Settings → Passwords, switch to a different iCloud account (each user should have their own), and Safari will pull in that account’s saved passwords and bookmarks. Note that this isn’t 100% isolated (some global Safari settings might overlap), but it works great for casual use cases.

The easiest, most hands-off method is leaning into Chrome’s built-in Google Account sync:

• On your first Mac, switch to the profile you want to sync. Click the profile icon in the top-right corner → Sync and Google services → turn on "Sync" (you can customize exactly what to sync: bookmarks, passwords, extensions, browsing history, etc.). Make sure this profile is linked to a unique Google Account (each user should have their own account for full separation).

• On your second Mac, open Chrome, click the profile icon → Add → sign in with the same Google Account. Chrome will automatically pull down all the profile’s data, including saved logins, extensions, and even open tabs. It stays synced in real-time, so any changes on one Mac show up on the other instantly.

If you don’t want to use a Google Account, you can manually backup/restore profiles (though this requires manual updates):

• Locate the profile folder on your source Mac: ~/Library/Application Support/Google/Chrome/Profile 1 (the number varies—check which folder matches your target profile).
• Copy this folder to your target Mac’s same directory (~/Library/Application Support/Google/Chrome/).
• Open Chrome, click the profile icon → Add → Import an existing profile → select the copied folder.
