Today I wanted to move existing APFS-resident macOS Catalina installation to a new disk. I upgraded my late 2014 Mac Mini with a shiny new 1TB SSD. This took way too many hours of my life I will never get back. Hope this saves some time to you.

Good news:

1. it is possible to create a DMG image from existing APFS container with macOS Catalina installation including metadata needed for complete restore (the DMG contains OS, OS Data, Preboot, Recovery and VM volumes)
2. it is possible to restore this DMG image into empty APFS container and get a bootable copy of the original system

This information is relevant for Catalina (I'm currently running macOS 10.15.1).

It is the year 2020 and replicating APFS containers still sucks. One would expect it would be a simple copy and paste in the Disk Utility app but this is still far from reality.

Last year I wrote how I managed to clone my macOS system under Catalina. The main trick was to create a DMG file with multiple volumes, mount it on target machine and drop to command-line to do asr restore from synthetised disk while avoiding possible pitfalls.

The good news is that Apple devs definitely worked on improving this under Big Sur and added some documentation (see man asr). But I didn't understand it fully on first read. Maybe someone could explain how is this supposed to work?

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
