Can’t resize APFS container

disk-spacehard drivepartition

On a 120GB SSD hard drive in a MacBook only 68.68GB are available. The missing 51.32GB are not even shown as a free space.

Here is what the output of Disk Utility looks like:

As you can see on the first screenshot the disk has 120GB. However, the partition chart on the same screenshot only shows 68.7GB. Also the other two screenshots show that only 68.7GB out of 120GB seem to be available.

The command diskutil list shows that the physical disk0 is 120GB big, but the synthesized disk1 only 68.7GB:

Just for the record. I've managed to increase the size of my APFS volume using GParted and Disk Utility (from macOS Catalina).

Create a GParted USB drive and boot from it
Use GParted to move the APFS partition/container around so that the free space appears directly AFTER the APFS partition.
Boot into Mac Recovery mode and open Disk Utility
Click the drop-down in the top left and enable "Show All Devices"
Select your SSD (top entry)
Click "Partition"
Somewhat unintuitive, but now select the "Free Space" area and click the "-" button below. This will "remove" the free space and enlarge the APFS container to fill it.
Confirm the dialog and the resizing should start.
Done.

Messed up the 1TB Fusion drive on the iMac with Disk Utility

I eventually made a call with Apple support. They asked me to use the option first aid in Disk Utility, this didn't help. They then asked me to reboot my iMac in recovery mode and do the same thing again. This also didn't help.

After these two options to repair my partition, they asked me to back-up whole drive and reinstall OSX. They told me that this would definitely work because the hard drive was a fusion drive, part mechanic and part ssd.. Can't remember the exact details on why this would work thought... But i reinstalled my whole OSX and got my 1TB back. :).

50GB of disk space missing

You previously installed Windows (or another OS) and deleted it afterwards - except an orphaned Apple_BOOT or 2nd EFI partition (disk0s3 - 134.2 MB).

The 50 GB are simply unallocated disk space.

To expand your APFS container you have to remove the third partition and resize the container:

First convert the third partition to free space:

sudo diskutil eraseVolume "Free Space" %noformat% /dev/disk0s3

Then expand your APFS container to the max (0 is a magic size here):

diskutil apfs resizeContainer disk0s2 0
