When the failure cause is a virus, malware or corruption of system files, recover the system from
the backup. Refer to Recovering your Mac (p. 18) for details.
To determine source of the problem:
1. Check the cables, connectors, power of external devices, etc.
2. Restart your Mac. Press and hold the Option key while the Mac is starting. The recovery menu
will be displayed.
3. Choose Disk Utility from the list, and then click Continue.

condition of the disk. For example, it may contain bad sectors. We recommend that you back up
the disk as soon as possible, and then replace it.

If there is an error, click Repair Disk. If the Disk Utility reports that the disk is OK or it has
been repaired, restart your Mac and continue using it as usual. If the errors persist, recover
your Mac from a True Image backup. Refer to Recovering your Mac (p. 18) for details.
If the Disk Utility does not detect any errors, recover your Mac from a True Image backup.
