macOS Sierra system is using over 200 GB of storage space on my 250 GB hard drive. I've removed Time Machine backups to no avail. How do I free up space? My current usable space being less than 50 GB is getting quite problematic.

Edit:

The culprit has been found. Imagemagick is creating tons of temp files for some reason.

The Solution

I used a storage scanning application to see where all the space was going. I used DaisyDisk, but Disk Inventory X is another option

Turns out ImageMagick image editing library was rampantly creating large files at /private/var/tmp
