A friend's Air has a smallish SSD drive; I went looking for space hogs. Her library seems to consuming 30+ GB. I spent a few minutes with du -h trying to see why, to no avail. (I did see all kinds of Mail stuff there; has Apple gone back to their OS8.5 days of putting mail in system-ish areas?) Is the virtual memory file in there somewhere? Or should I keep looking for something huge?
