I've been using mavericks for about a week now, and I love it.
There's only one thing that's bugging me quite a lot at the minute.
In OS10 Mountain Lion, notifications like "the disc wasn't ejected properly", or "none of your preferred wireless networks are available" appeared as separate finder windows.
However, in OS10 mavericks, they now show in the upper right hand corner of the display, and I haven't found a way with VO to get at them.
Another example happens when you first install mavericks. You get a notification saying welcome to mavericks.
The only way I've found to get rid of them is when a sited person dismisses them for me, as I don't know they're there and they obstruct the screen.
Hope you guys can help me.
