Call it OS X 10.9 DP 3, 13A510d or Beta 3 if you like, but it’s all the same to the rest of us. What's new? No big changes, but lots of little things…

Call it OS X 10.9 Developer Preview 3, 13A510d or Beta 3 if you like, but it’s all the same to the rest of us. Whereas the previous beta, 13A497d, arrived chockablock with new features, tweaks and fixes, this particular Mavericks developer seed seems to be about bug fixes.

First, let’s start with some observations by OS X 10.9 13A510d beta testers who say, for example, that Safari 7 seems to be snappy again, like it was in the first developer preview. Similarly, some MacBook Pro Retina owners are self-reporting that battery performance has improved by double digits.

Additionally, informed sources say Safari 7 now seems to be aware (i.e. automagical detection) of more plugins/network protocols, such as GoogleTalk.

Apple has apparently included a new version of Messages in OS X 10.9 13A510d, though it isn’t known what new features it might bring.

What hasn’t changed? iBooks still hasn’t shown up. Moreover, Apple’s still shipping old versions of GameCenter and Reminders.

A Fairer Platform informant reports that there are few if any new/updated networking or graphic driver frameworks in OS X 10.9 13510d.

That said, please enjoy the seed notes…
