Mavericks 10.9.1 Bugs

What are the most annoying bugs currently plaguing your Apple machine.

For me it is the Sleep/No Audio Bug - happens when your machine goes to sleep and after it wakes up there is no sound. According to Apple Discussion users, disabling Power Nap is the workaround. Previously, the only solution know to me was to reboot.

On a side note, do you feel the these issues are annoying? WIth Jobs around, I bet Mavericks would have been a better release with less bugs.
