Hi all, The strangest thing is happening to me right now and I can't come up with an explanation for this. I had about 20 GB free space on a 1TB hard drive on my MacBook. I went to the App store and downloaded an updated for the official Twitter app. Shortly after I checked my HD space again and found that it had ballooned to 50GB of free space! I was gobsmacked and could not figure out what could have caused this. I decided to restart my computer. Perhaps Finder was glitching and the count was all wrong? Well, when it came back to the desktop after restart I found that I now had 200GB of free space- and still growing, megabyte by megabyte. I can't seem to find any files that could have been mysteriously deleted. Is this somehow related to the Twitter app? I don't see how it could be but that is the only thing that I did out of the ordinary right before I noticed the spike in space. If anyone can offer any explanation it would be greatly appreciated.
