I updated to Mavericks because it has some great features. I didn't anticipate it sucking. My Safari loads pages slower for sure. Sometimes if I swipe as if to go back in history in safari, it goes half an inch and the tab freezes. I have to close that tab because its useless. Minecraft gets 30 FPS compared to the 60 or so I got on ML. I've already repaired permissions and restarted a few times and its not gotten better. I'm afraid I may have to install a partition with ML on it to hold me over until Mavericks gets on top of its game. What do you all think of it? Anyone with similar experiences?
