Remove or Resize APFS Volumes

[DuncanGarp]

Hello Folks,

I have an internal 160gb SSD that has 2 APFS partitions (actually volumes, 80gb each). One contained Mojave and the other High Sierra. I decided to just use Mojave exclusively on this mac, and erased the 2nd volume containing HS. Now I want to either erase the HS volume or downsize so I could use it for Mojave (80+80gb). Using Disk Utility, it does not let me. Googled the right step or solution but did not find one.
Running "diskutil list" in terminal displayed the following screen shot.



As you can see from the screenshot, "disk2" is my Mojave boot drive, and "disk1" is the other volume that I need to either remove or resize so I could increase the "disk2" available size. As I mentioned above, could not do it using Disk Utility. If you know of any sudo commands in Terminal or another step, please suggest.

Appreciate suggestion or solution.

disk1 and disk2 are two separate containers. I ran into the same problem. For now, there is no way to merge two containers into one.

Easiest (but also most time-consuming) is probably to make a backup of disk2 (particularly disk2s2), remove it, resize disk1 to fill the entire physical disk, and then add a second volume to disk1 onto which you restore the backup.

Because of the way containers work, both new volumes will then have the full capacity available.

I sort of did the same as @chucker23n1. I backed-up the boot drive in Time Machine. Erased the multiple volumes, re-created the container and came up with a single container. And here's the difference from @chucker23n1's steps. Installed Mojave on that single container and then "transferred" all my settings from the Time Machine backup. It is time consuming. But it works as far as all the custom steps and apps I made on the OS.

My recommendation for Apple ~ Disk Utility features should be updated to be able to do this time consuming steps within the app itself.
