I am having problems recapturing space on my SSD. Mojave wouldn't let me update from 10.14.1 to 10.14.4 so I created a partition formatted APFS and installed Mojave 10.14.4. Then erased the old partition and formatted it apfs then deleted the container then deleted its volume at the terminal: sudo diskutil eraseVolume "Free Space" %noformat% /dev/disk0s3. I have been trying to resize the remaining container to get the free space on the 1TB disk,with the resizeContainer command. What am I doing wrong?
