I have an application that needs a support folder in /Library/
Application Support. This folder is created when my installation
package is run and has the following permissions:
drwxrwxrwx 6 root admin 204 Aug 10 18:09 Foo
When running the 10.6 upgrade to Snow Leopard from 10.5, the
permissions get changed to:
drwxr-xr-x 6 root admin 204 Aug 10 18:09 Foo
This has the side effect of preventing the application from writing
to the folder when run as a user other than root. Changing the
permissions back to drwxrwxrwx after the upgrade fixes the problem,
but I'd rather release a preemptive patch to fix this rather than
dealing with it on the customer support side. Any suggestions?
You can try storing your data in in /Users/Shared instead of
Application Support. I'm not sure what the official recommendation is,
but I'd take Apple changing the permissions behind your back as an
unofficial recommendation, since it's obviously too late for them to
change.

My two previous responses were bounced since my iPhone apparently can
only send from my @me.com account but not from my subscribed @mac.com
account. Listmom: should I unsubscribe/resubscribe?
I commented that HOBOware (an application used by one of my clients to
monitor/trend the temperature, humidity, etc., of their art storage
areas) has the same issue. It was designed to be installed for a
single user (it installs into ~/Library/Application\ Support), and
assumed the user has admin rights.
After discussions with the developer going over our managed
environment (users are non-admins, AD/OD golden triangle environment),
we came up with a solution that would allow the installer to put its
stuff into the /Library/Application\ Support folder, then a login
script would kick in once per user to copy stuff from /Library/
Application\ Support/HOBOware/ directory into the users' ~/Library/
Application\ Support/HOBOware/ folder so the application would
reference the "user" domain data (the script would then delete itself).
HOBOware obviously needs to be rewritten to respect/adhere to the
Apple software distribution guidelines. Note how /Users directory
(and /Users/Shared) should not be used for installs:

PS, thanks to the folks on this list (and a couple others) for the
login script workaround. :)
