How can I modify MacOS image

[ddkurguzikova]

I want to modify image of macos (add some libs for automatic running)

1. I do all my steps (as installing homebrew)
2. copy mac_hdd_ng.img from container to host
3. create new docker image containing modifying image instead of old one

In running stage I stuck in ssh: Connection refused loop

What should I do?

Could you give me info step by step how can I save all the changes I made inside of docker image?

And than I copy with docker cp mac_hdd_ng_auto to host
And than I modify Dockerfile and copy with COPY command image
