Anyone having input issues since yesterday's updates? Since installing all the OS X updates yesterday my mouse and keyboard are really going nuts. Seemingly at random the mouse cursor will jump across the screen or keystrokes will repeat. It's really, really annoying. Like unusable-annoying. I know one of yesterday's updates was a firmware update for the Mac Pro. Everything installed OK but this input issue is really frustrating. Is this some sort of bad after effect of the recent OS updates or is my computer f'd?
