Missing space after deleting bootcamp partition
Solution 1:
I believe the commands below will return the free space to your "Macintosh HD" volume.
diskutil resizevolume disk0s3 650M
diskutil unmount disk0s3
diskutil cs resizestack 7FA484C3-705F-4C19-B060-659CEB006623 0
To be sure of the 650M value, I would first need to see the output from the command given below.
diskutil resizevolume disk0s3 limits
