Mac: resize APFS container
resize a disk container to increase the size
If you have a disk that was 50GB but want to increase it to 100GB run the following from the terminal to increase the container size.
diskutil list
You should see a list of your drives. Find the one marked:
Apple_APFS Container disk x
And look for the identifier, something like:
disk2s2
In my instance disk2s2 references disk 3.
So disk2 is physical and disk 3 is synthesized.
We now repair the physical disk, disk2:
diskutil repairdisk disk2
Ignore the EFI warning.
Finally run:
sudo diskutil apfs resizeContainer disk2s2 100g
