MacBook HD "Other" all of a sudden almost full As you can see in the below image, my HD "Other" category is almost full. A couple of days ago, I randomly kept getting a popup saying that my disk was almost full. Then I went in and noticed the issue in the image. I ran the repair disk utility and got all my software up to date, to no avail. Haven't found any help on Google. Any ideas?
Not sure whether you've already found this, but there are a number of other people having the same issue on the Apple Discussion Groups. There seems to be quite a lot of good information in that thread so I recommend reading it through, but the consensus seems to be that its hidden local backups/snapshots that's causing it.

A few people also used DaisyDisk to find, then delete, hidden space on the hard disk.
