I have trouble accessing data with an encrypted APFS volume on mac 10.13 High Sierra. It refuses to open all passwords, and neither could I find it in Disk Utility. The error was: Error unlocking APFS Volume: Couldn't mount disk (-69842). Is there any way to fix this issue? This article offers you the best data recovery software to get back your important files.


After upgrading to macOS Mojave 10.14's High Sierra 10.13, our Mac internal hard drive will not only be formatted to be APFS but also will be automatically encrypted. Sometimes, some errors happen to our APFS drive and make it can't be unlocked even with the right password. At that time, it can't be mounted, unmounted, or even ejected, and also cause the Disk Utility to freeze whenever connected. When plugged, it asks for the "'Error unlocking APFS Volume: The given APFS Volume is not locked (-69589)" one time. If it is correct, it asks for a second time, but the disk does not mount after that message box disappear.
