I was trying to get rid of an old Bootcamp partition I didn't want anymore. I followed these instructions to remove a partition using Disk Utility, but the removal failed. Now the partition is gone, but the space it used to occupy hasn't been merged back to the main disk partition - it's just gone. My SSD is 1 TB, but Macintosh HD is only 775 GB, the same as it used to be.
What happened to this extra space and how can I get it back? And why did it leave me in this weird half-removed position instead of removing the partition properly?
Here's what my Disk Utility looks like now:
Here's what comes up when I enter "diskutil list":
