I truly appreciate your frustration and agree that you are obviously *not*
the only one with the problem. Consider, however, the number of users who
have *not* experienced any such difficulty.
Therefore it can be safely concluded that the update, itself, isn't at
fault. Otherwise there would be quite a few more instances of the problem -
more likely, it would be universal for all who attempted to use it. It is
far more logical that those who incur the problem are actually having some
sort of local configuration issue blocking the installation. Unfortunately,
that *doesn't* dictate that it is the *same* demon in each instance. That
makes it quite difficult to be able to provide any 'canned' fix.
If you haven't yet done so thee is one thing that seems to make a difference
for some - I know it rectified some minor after-the-fact issues I had with
11.3 which were actually caused by OS X 10.4.8. D/l the 10.4.8 Combo updater
from the Apple web site rather than using Software Update. Re-install it,
repair permissions & restart, then try the 11.3 updater from Mactopia again.
Any feedback you can provide may help others with the same problem.
