It is unclear what improvements the 10.9.4 update will bring to Mavericks, but it is likely to include bug fixes and stability enhancements. It is also unclear when the beta might be released to the public.

The last Mavericks update, 10.9.3, added enhanced support for 4K displays and restored the ability to sync contacts and calendars between Mac and iOS devices over USB.

I hope they solved the Magic Mouse problems with Mavericks: The cursor doesn't move any more.

You sure the battery isn't dead? :)

Uggg! No thank you!

I think they may have learnt a lot from iOS 7 and the overhaul won't be anywhere near as drastic.

A flatter UI without sacrificing productivity would be most welcome from me. I don't want change for the sake of it with reduced functionality.

Not gonna lie, miss going up to .x.8 or even .x.11.. it just feels so.... I dunno. Bleh.

I don't feel like I got my money's worth. I paid zero American Dollars for this OS, I expect updates till at least 10.9.5.

I'm not sure... I think you may have.... I don't think you followed Apple's train of thought on that one... ;)

I think its safe to say that Mavericks will reach 10.9.5 before OS X 10.10 is released.

Hopefully the wifi disconnection after wakeup, which is not fixed in 9.3, is what they are fixing with the new beta.

whats wrong with iOS 7.1.1 thats driving the urgent desire for iOS 8.0? it's a year old already and i want something new, plus it has some bugs still.

Hey now, iOS 7 isn't a year old for another 4 months. Let's not jump the gun. :p
