How do I search the forums for a version of MacOS? For example, I want to search for any post containing the string "10.5.4". I've tried "10.5.4", "10\.5\.4" (escape the periods in case they're regexps, although it would *still* match since the "." regexp metacharacter would match "." literal), "10 5 4"; with no results. This is an obvious search string every time there is a new version of MacOS. (I've tested with "10.5.3" and varients, which I know is in quite a few posts, but it also returns 0 results.) Thanks! Regards.
