I was trying to use Boot Camp Assistant to create a Windows 10 partition, but it got stuck at partitioning. After about a hour, I gave up and force quit the Assistant, and discovered that 3 terabytes of disk space was missing (the amount I was partitioning for windows).
I tried to use Disk Utility to remove the partition, but it doesn't even show up on Disk Utility!
These are the results from `diskutil cs list` and `diskutil list`
`diskutil cs list`
