Download OS X 10.9.2
You guys probably already know about this, but Apple released OS X 10.9.2. It fixes the SSL bug and brings FaceTime audio to the Mac, but most importantly IT FIXES THE GODDAMN LAUNCHPAD LAG. It's been bothering me since Mavericks was released and I'm glad to see that it's finally been fixed. Of course there are various other bug fixes and improvements that you can see in the release notes.
