Ok, i've had this question for a while, and was looking for a thread on the subject but couldn't find one. Why is it that my Macintosh HD won't update to the actual free space? I mean, some minutes ago it said 83Gb free, and then i promptly deleted over 60Gb of backup files from software downloads i've made over a couple of months (and yes i emptied the trash can), and now it says 88 Gb free... last time i checked 83 + 60 is not 88. Why doesn't it update to the actual free amount? I've continued deleting large amounts of data, and it still won't show the space being freed. Do i have to reboot for it to show? Or is the space not recuperating because something is wrong? Is this normal???
