Hi all,

Disk Utility First Aid is saying my boot disk is corrupt.This is my work computer so I want to keep it reliable. It works fine, but very occasionally freezes.

This is the error I am getting from running First Aid with my MPB in Recovery mode:
  • error: container keybag (101286206+1): unlock records entry 0 contains invalid range 218373742+1
  • error: volume keybag (218373742+1): failed to get keybag: Device not configured
  • Encryption key structures are invalid.
How do I sort this out? This is my work computer so I want to keep it reliable. It works fine, but occasionally freezes.

Full details below.

Thanks!
