A long while back I recall installing Linux on my macbook. I have since deleted it, but the partitions on my disk are somewhat screwy. I cannot reclaim the free space to my main Macintosh HD partition (only to recovery).

Any ideas for how to reclaim it? If there is a way which wipes the drives I'm fine with that. See below picture and diskutil output.

Any and all advice welcome :)

Showing that I can only resize to recovery:

With versions of macOS, which are installed in an APFS container, there is no need for a separate recovery partition. Therefore, you should be able to delete the recovery partition with the command given below.

diskutil erasevolume free none disk0s3

With the recovery partition deleted, you should be able to add the free space to the APFS container by using the command below.

diskutil apfs resizecontainer disk0s2 0
