Which is what is perfectly correct and intended to work that way.

I am writing to some files regularly during execution. The problem is when I installed application with one user and then login with other user account than privilage exception is raised. Is there any way to solve this problem. Yes, fix your application to only write to the approved directories (like ~/Library/Preferences or ~/Library/Application Support, their counterparts at /Library/... or /tmp (or even /var/... if you must) for example, depending on what type of information you're writing. There are a number of good reasons for this but one is that it may not even be possible to write to the application even with the correct permissions and authorization because the volume it's on is read only. Another is that two instances of your application might run on the same machine in different user contexts which will probably scramble the files you're writing to unless you are taking great care to ensure proper locking. A third is that standard users SHOULD not be able to modify your application for security reasons. Anybody who sets up a system to use standard (non-admin) users does this for a reason and you don't want to make their efforts be in vain. I'd throw out any app I'd catch violating these rules. This topic has been discussed numerous times on the Carbon-dev mailing list. Check out the archives for more good reasons and correct solutions to the problem. Hint: Use FSFindFolder() to find suitable directories for saving your data. This email sent to site_archiver@lists.apple.com
