I'm on an early 2008 8-core Mac Pro. Mavericks seems to run fine but it's a little slow. For example when opening disk utility, the screen fades in as usual, but it stops for 1 or 2 seconds when it's halfway faded in, then fades all the way in. Opening Firefox takes 3, nearly 4 seconds to open after clicking it as well. I've got windows 7 installed on this machine as well and everything is lightning fast when I boot into it. I've checked and Spotlight isn't indexing noted by the little dot in the magnifying glass not being there, so I'm not sure what's going on. Is there anything else I should check for? Or should I just wait until a new update for Mavericks is released?
