    My rMBP had about 8GB but now it has 345MB. I don’t remember downloading anything. What could have happened?


    Interesting, after I reboot the computer the problem was fixed and the storage space returned to normal.

    Download and use OmniDiskSweeper. It will provide a sorted list of what's consuming your space.

    If you run it with sudo (As shown below), it will include some system files that it woud not normally have access to scan. That is a more accurate representation of what's consuming your drive.
    sudo /Applications/
    Another option is to use this terminal command
    sudo du -d 1 -x -c -g /

    I prefer to redirect it to a text file (this puts it in your Documents folder
    sudo du -d 1 -x -c -g / > ~/Documents/du.txt

    Like the sudo /Applications/ command, it will scan all directories, but produce a text file as opposed to showing the results in a window

    If you rebooted and it cleared up, it could be the swap files, or perhaps some other temporary type files that the system cleaned up on reboot.
