    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

    thank you. this is the first time I've seen it fall that low, and then the GB available has gone up again tonight by around 10GB, I'm pretty sure in all the years I've owned the MBP I've never seen it fluctuate, but it has today.
