I’m trying to sort my applications by Last Opened column, but the option is not clickable (is grayed out) in the view options (⌘+J) panel (see image below).
Why and how can I fix this?
(I’m on Snow Leopard 10.6.8)
Date last opened was only available in Spotlight windows in 10.6 and earlier. It became available in normal Finder windows in 10.7.
