In OS X 10.7 ‘Lion’, when you right-click an icon on the dock, it shows you a list of the “most recent” items for that application. The same files appear in the application exposé. For me at least, it also lists items I already deleted. Maybe it’s a bug, maybe it’s feature.
I tried clearing the history through ⇢ Recent Items ⇢ Clear Menu. That didn’t work. Turns out I was just looking at the wrong place. It’s a per application setting. You have to clear it for every single application. Takes a while, but once it’s done, it’s done.
And that’s how you do it:
- Open the application.
- Go to the menu bar
- File ⇢ Open Recent ⇢ Clear Menu
- Restart the application
If you don’t restart the application,it will keep the history until you do.
Update:As pointed out by James this might not work in every application. Some applications need you to log out and back in again. Apple really needs to fix this as soon as possible. This should work without relogging or quitting applications.
