Safe Boot is perfoming a disk integrity check and repair process which may take a long time. Let it complete, though if the startup disk requires repair to begin with, it is likely already in a failed state.


If the Mac eventually starts, take that opportunity to back up your important data if you have not already done so. It may be your last.
