I think you're wrong about it working for a non-admin user in Tiger,
since:
a) It's do***ented that you can't save such changes: "Note that you can
only save preferences for łAny User˛ if you have Admin privileges."
b) I've been using that routine since (at least) 10.2 and it has behaved
as do***ented.
So I'd say either it's not saving or your 10.4 user *is* an admin
despite what you think.
Your options are:
a) Only save this change when running as an admin user; if the synch
fails, fall back to user-local storage.
b) Write someplace else, essentially recreating a ****tion of the
CFPreferences API.
c) Use some form of privilege escalation like a single-purpose setuid
tool running as root to save this setting.
I advocate course (a) unless it's critical that this value be identical
for all users. (b) and (c) both have shortcomings that are beyond the
scope of this message - the increased complexity in comparison to (a) is
probably the least of your worries.
