iMac would not boot up past Grey Apple screen on repeated attempts.  tried to reboot in safe mode with tracking on and after several lines of boot up code it stopped and I get a reparated disk0s2: I/O error. message.

 

What does this mean?

    kernel[0]: disk0s2: I/O error.

     

    My iMac starts up slow and often stops working during the day after these errors.  I run the Disk Utility frequently and it never finds any errors, but it is only a bandaid. How do I fix the issue ?

    The I/O error and the other symptoms strongly suggests the drive is failing. First thing is to make a backup immediately.

     

    After that test with the free demo of SMART Utility.
