dpclark said:True, but a lot of the apps have new versions for tiger - safari and mail off the top of my head.
Exactly, that's the point. There are new version of many of the bundled applications and some of those may still have problems. However, that doesn't mean that the OS itself couldn't already be declared GM. If the new version of Safari/Mail/etc. still had problems they couldn't ship the Tiger retail packages until those application bugs were fixed (if the problems were serious). In a perfect world that type of dependency wouldn't be allowed to happen since application compatibility for any OS release is a very important metric and problems such as this would usually be resolved well before the final release of a new OS, but bad things can happen.
