I have all of the problems described in the article [1] except for spinning beach balls. The IOHIDSystem problem is claimed to disappear if you do the sandbox fix, but it did not help in my case. I don't have SIMBL plugins, I don't have extensions such as FUSE, or otherwise any weird software that could be the culprit. I don't deny that it's possible that there is something else. But I have spent a lot of time on this already, and not found anything.
