How can I merge primary APFS partition with other empty APFS partition?

After reading and following the above, I got stuck on the eraseVolume "Free Space" and now that space seems irrevocably lost. Did apfs resizeContainer but got Error: -69743: The new size must be different than the existing size and it seems that my 2TB physical drive can recognise only 999.4GB... enter image description here

any help?

    Are you trying to do this whilst booted from it? It won't let you saw off the branch you're sitting on.

  • Can you restart the Mac and then post the output from the commands diskutil list disk0 and diskutil info disk0s2 | grep -e Size -e Offset? Edit your question and place the output there. Oct 29 '20 at 23:12
