Just wanted a heat map of the system drive

I went with this app in lieu of the free ‘Grand Perspective since it was in the app store. Unfortunately, it only found ~70GB worth of content in a 256GB drive. I installed and ran the free app, and it found all the items that were taking up space. I feel like I wasted $5. :(
