MacOS may lose data on APFS-formatted disk images
I upgraded my hackintosh to High Sierra with APFS. The next day, I accidentally switched off the machine while it was in the _process_ of shutting down (the screen had gone blank, but casing still emitting lights).<p>Next time I turned it on, I couldn't get past login screen (giving me forever beach ball).<p>I put the ssd inside my old MBP as slave to recover data.<p>The ssd was corrupted, most data gone, as in shown in Finder but couldn't be copied.<p>I googled for solutions, but it seems I'm the first to experience this.
