– quit Safari
### = your username
– delete, move or rename ~ /Users/###/Library/Safari/History.plist
– start Safari again
If you want to stop safari from recording the address bar history then do the following:
Choose History: Clear History, and then quit Safari.
In your user folder, go to Library/Safari and locate the history.plist file.
Select the file, choose File: Get Info, and then click on the Locked option.
Now close the window.
When you relaunch Safari, autocompletion will still work as expected on bookmarks, and it will also work for URLs you visit in the current session.
But the next time you quit and restart Safari, the autocompletion data will vanish — it can’t be written to the locked .plist file.
To return to normal autocompletion, deselect the Locked option in the history.plist file’s Get Info dialog box.
