I had previously set up my 2012 Macbook Pro in a fusion drive configuration (250GB ssd and 500GB HD) for macOS and had a 250ish GB partition for Windows on my 500 GB hard drive. I tried removing the partition using disk utility but seem to have gotten into a bit of a mess as I can no longer see the previously partitioned space in disk utility and my macOS partition has not resized to make use of the full 750 GB which shoud now be available to it. I would greatly appreciate any help in resolving this issue and enabling my macOS partition to use the full storage available to it (whilst preferably keeping the fusion drive configuration).

I have run diskutil list from Terminal in recovery mode to obtain the following:

-bash-3.2# diskutil list

  • Can I assume you have already tried the command diskutil apfs resizecontainer disk0s2 0? If this did not work, then post the output from the command diskutil info disk0s2 | grep -e Offset -e Size. – David Anderson Jul 18 at 18:30
  • Thanks for the info @ankiiiiiii, my partition structure looked a bit different to the others I saw so I didn't want to mess anything up – Jash15 Jul 18 at 21:04
  • @DavidAnderson Cheers, have just tried the first command and got an error: – Jash15 Jul 18 at 21:05
