macOS Sierra "System" files eating up disk space 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
