Since I updated my MBP, it doesn’t work anymore. Had trouble installing, then it was slow, and now I can’t do anything anymore other then going into Recovery mode. When running Disk Ultility, it always tell me while running First Aid, that there is an error: cib: o_oid(0x0) File system check exit code is 0. I don’t know what to do anymore.

Lets try to repair your disk in Single User mode.

Hold Shift key during start up.

Let it finish ..

then enter

/sbin/fsck -fy 

When it’s done, you’ll see a message saying “** The volume [name] appears to be OK” if everything is fine.

If it found problems, you’ll see a “***** FILE SYSTEM WAS MODIFIED *****” message. This indicates the fsck command found and fixed problems. The fsck command may find additional errors after repairing the first batch of errors, so Apple recommends you run the fsck command again if it found and fixed problems. Run the above fsck command over and over until you see a “** The volume [name] appears to be OK” message.

When the fsck command says your disk is okay, type the following command at the terminal and press Enter:

reboot
