Hi, I'm on Mac OS X Lion, 10.7.5. My mac seems to be getting really slowed down by something called mdworker. It's taking up all of my ram. Yes, spotlight is indexing, but sometimes it randomly stops, and starts again. And, I mean really, really slow. Please help! EDIT: Now something's taking up all of my CPU usage, and ram. It's not even mdworker, and nothing running is using that much power! EDIT: I just force shutdown, and restarted, and it all seems okay.
