Monterey retake space from free space partition

Question

I have tried the method from this page but I cannot manage to reclaim the free space.

Output of diskutil list:

diskutil list
/dev/disk0 (internal, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER

And then I tired code diskutil apfs resizecontainer disk1 0

diskutil apfs resizecontainer disk1 0
Started APFS operation
Error: -69519: The target disk is too small for this operation, or a gap is required in your partition map which is missing or too small, which is often caused by an attempt to grow a partition beyond the beginning of another partition or beyond the end of partition map usable space

Now there is 799 GB of free space in my Macbook and I cannot use it.

Anyone could help me?

Answer 1

In my opinion, you question appears to show you are entering commands without understanding in the hope something desirable will happen. This a dangerous approach which could lead to the loss of important data. The answer below is less dependent on commands than the answer you have linked to. Hopefully, this increase the change of success.

1. Open a Terminal application window and enter the command below.

   diskutil addpartition disk0s1 apfs NewMacHD 0
   

2. Download Monterey from the App Store.

3. Install Monterey to volume NewMacHD. After you are convinced Monterey is installed to the NewMacHD volume, move the Install macOS Monterey application to the Trash.

4. Boot to Monterey on the NewMacHD volume.

5. Use the Migration Assistant to transfer from the Macintosh HD volume to the NewMacHD volume.

6. After you convinced all useful data has been migrated, use the Disk Utility to delete the partition containing the Macintosh HD volume.

   Note: After using the Disk Utility to perform an operation, you should quit and then open the Disk Utility to see the results.

7. Use the Disk Utility to rename the NewMacHD volume to Macintosh HD.
