Its messing with my web browser on my Mid-2001 MacBook Pro .... popup windows almost freeze the computer for 20-30 seconds ...
I looked in the forums, and it seems to be a very common side effect ...
I would love to go back to Mountain Lion, but I am too lazy ... I'm hoping they will roll out a fix before it pisses me off enough to backup and uninstall ...
All I can say is Mavericks was well-priced ......
