Answer 1

As an alternative solution:

Change the path from /private/instance1-data:/home to ./instance1-data:/home

In the *nix land and hence, Docker, the . indicates the current directory. Since macOS is picky ang getting even pickier about sandboxing, this seems like a viable solution for macOS. Just create the folder needed for instance1 in the same directory.

Another advantage of this solution is that it removes the need to run docker-compose with sudo. Regardless, it causes no harm in this case but still, that's a plus.
