How to remove an auto-complete suggestion from Safari

Hi agd21,

While there's not a list that you could modify in that way, the results you see are based on your browsing history, so it might help to clear that if you haven't tried it already. Check out this link for the steps: Clear your browsing history in Safari on Mac - Apple Support

"Clear your browsing history in Safari on Mac

You can remove all records that Safari keeps of where you’ve browsed during a period of time you choose. If your Mac and your other Apple devices have Safari turned on in iCloud settings, your browsing history is removed from all of them. Clearing your browsing history in Safari doesn’t clear any browsing histories kept independently by websites you visited.

1. In the Safari app  on your Mac, choose History > Clear History, then click the pop-up menu.
2. Choose how far back you want your browsing history cleared."

Take care.

Hello agd21,

You can disable Siri Suggestions for Safari on Mac with the following related steps: How Siri Suggestions work on Mac - Apple Support

Customize Siri Suggestions

1. On your Mac, choose Apple menu  > System Settings, then click Siri & Spotlight  in the sidebar. (You may need to scroll down.)

2. On the right, click Siri Suggestions & Privacy.

3. Select apps in the list to turn “Show Siri Suggestions in [app]” or “Learn from this application” on or off.

Disabling Safari in Siri Suggestions should stop it from auto-populating these websites moving forward.

Let us know if that solves the issue for you.

Take care.
