Strict permissions? Not intentionally! The problem thatd sent my Mac
to the guru was that Terminal used my full name on every command line,
using up too much space where a simple 'fm' would have been fine. One
needed to set up a new user to change this behavior; when I got the
new user set up, he didn't have access to anything. I got tired of
changing permissions and made the whole disk accessible to myself
under any user name. Then I neglected to repair permissions, which
evidently protects some essential files from something, because things
went to pieces in a hurry.

Now, in addition to any Unix-related problems, I may have an
idiosyncratic Mac problem. When my Mac guru put Snow Leopard on it
(while he was repairing the permissions problem), he set me up with no
password for my user account. This appears to be the password that
sudo expects--but as of OS X 10.5 (I have 10.6.4), a carriage return
is no longer recognized as indicating 'no password', and gets the
standard error message.

There is a way of changing the root password, described by Apple at
http://support.apple.com/kb/ht1528
but so far no version of this has had any effect. Nor has chmod had
any effect.

There is considerable confusion in my mind about passwords, and I
haven't experimented with changing my user account password. Half the
time I get the impression that this is the same as the root password--
but then why are there different ways of changing the 2? Experience
suggests that the most probable result of messing about with passwords
is that I will end up trying to get my machine back into the hands of
the local guru--who is 50 km away and 500 m higher up the mountain,
not on a bus line, and me with a bicycle. So I experiment somewhat
reluctantly. Got any expert Snow Leopards around there?
