Spotlight Indexing?
I've never seen this before, but I went up to Spotlight and it was indexing. What is this, how often does it happen, and what does it mean?
I've had a few weird things happen in the past 10 minutes where my computer completely froze, I hit the power button to reboot it, then I had a prompt come up asking for my FaceTime ID. From there I noticed the Spotlight Indexing thing.
