296 Macintosh
User's
Handbook
The
solution
to
the first category
is
simple. Either the Mac
is
not connected together correctly,
or
some internal
part
is
broken.
Of
course,
if
the former problem occurs, you can solve
it easily.
If
an
internal Mac
part
is
broken,
the owner should
take
it
to
an
authorized dealer and have it repaired. We
do
not
recommend
that
you
attempt
to
repair
the
Mac.
This
chapter
includes hints on troubleshooting Macintosh
hardware and software problems. This will include problems
with the:
• Display
• Disks
and
disk drive
• Keyboard
• Mouse
• Printer
The Mac
computer
hardware
is
quite durable so many
of
these problems may never occur.
The
software within the sys-
tem may be the source
of
problems during normal operation.
Since the software must manage all
of
the computer's re-
sources, it
is
very complex. Such complexity
is
difficult
or
even
impossible
to
perfect.
The system programming which is included with
your
Mac is the end result
of
many man-years
of
programming time.
The
resulting work has undergone extensive testing
and
should
operate with no trouble. However, Apple
computer
engineers
are constantly working
to
improve the software. As a result,
updated versions
are
released
on
a fairly regular basis.
Be
certain
that
all software included in
your
system was created
under
the same version
of
the
operating
system. Mixing files
from one version
to
another
may cause
undo
problems.
To determine the version for the system, return to the
Finder
and
select
About
the
Finder
from the Apple menu. This
information can be determined for
an
application by choosing
the same
option
from the same menu after the application has
been chosen.
