Next up, we find a thing called libfsapfs currently being maintained/created/updated with a different hand written APFS parser, and this one includes support for reading encrypted volumes!Īlso it looks like libfsapfs includes some binary utilities so we won’t have to interface with the library directly for quick tests.įsapfsinfo 20191104 Missing source file or device. What about APFS recovery tools lurking around on GitHub? If a random anonymous online app can fix my drive, what about public utilities? A read-only apfs info utilįirst, we found apfs-tools (via Apple SE: Accessing unmountable APFS Volume on a disk image) currently being maintained/created/updated with a hand written APFS parser - but, it won’t open my encrypted APFS volume, and Apple’s own tools won’t provide a decrypted volume view because diskutil apfs unlockVolume doesn’t recognize the broken APFS volume or drive at all. Actually restoring files costs $99.īefore I throw away $99 to recover within-arms-reach files, I do some more searching… either the people behind this utility reverse engineered APFS from half complete docs Apple provides or they are using other public code underneath (spoiler: I never found out if the utility was all custom code or reusing open source code just packaged in a UI 1).

I launched VLC to watch something from my media drive and… my 2 TB USB drive wasn’t mounted. Now with windows restored to how they looked at the last backup checkpoint two weeks ago, let’s see what else went wrong during a double crashing reboot. So, off to old backups to restore Chrome windows/tabs and Terminal windows/tabs from old saved states. Not good.Īfter the next reboot, the system started okay, but since applications crashed while starting, they lost all of their historical state. MacOS hard panicked on me with a graphics driver corruption error 2 (which happened after seven “gpuRestart” logs were generated back-to-back).Īfter a forced reboot and re-login, the system crashed again while applications were starting up. If you only care about the answer, jump to the last section. sv_hourly_no00._2200/ ….I spent a day figuring out how to look into a corrupt encrypted APFS partition.
