Please help me brainstorm this topic. I am getting more and more broken APFS OS Partitions. Mostly Catalina but also Big Sur and Monterey. I could recover data using disk drill, r-studio and other data recovery software but Id like to find reliable way to mount or repair or reinstall or migrate operating systems with applications, settings and data. Im almost sure that there is no available tool to fix directory on APFS volume or force mount it and Disk Utility repair is not helping either. Has anyone found a way to recover not mountable APFS OS with apps and settings?Has anyone successfully tried cloning data recovered with other app into other working APFS volume and then migrate again or reinstall OS on top of it?

So far other than what Apple supplies within Disk Utility there is no 3rd party tool to fix APFS volumes or low level corruption. The only way is to nuke the drive fully and then reformatting it. Even that only goes so far as there are boot block elements which can become over worn requiring a new SSD. Using a bootable external drive (macOS Sierra 10.12) which I’ve also installed the OS installer app and DX Drive to see how worn the SSD is as far as I go in checking it. Reformat the drive using the external drive as your boot drive so there is nothing holding your internal drive open. I even go as far as formatting it GUID and a journaled file system (now called Mac Extended) which is the older HFS+ structure and then check it out using some drive testing apps. But be careful! The testing apps will write and rewrite data on the drive each time stealing a bit of life from the SSD. Then run the the OS installer, I start with macOS Mojave (10.14.6) on the Intel systems, then upgrade to what the customer wants.
