Anyon else having their Mac Pro lock up with mavericks? Ever since I updated to mavericks, it will just all of a sudden lock up and a few seconds later beach ball of death strikes for the final blow. Nothing responds and then I have to Dow force shutdown. I been running windows more and no problems so it's obviously software. Maybe it's the drivers for the titan locking up since it seems like the latest drivers are lacking for mavericks?
