Reinstall OS X
If worse comes to worst and Mac Pro will not start or if your system is completely unstable,
then you need to reinstall the operating system. The most common scenario for reinstalling
OS X is when Mac Pro does not start, and repairing the hard drive as described in Chapter
15
has no effect. Another common scenario is when Mac Pro suffers from frequent lockups,
application crashes, and other unstable behavior, and deleting preference files, as described
in the section “
Delete a Program's Preferences
,” and repairing disk permissions, as de-
scribed in Chapter
15
, have no effect.
