Mac app to read system log file

What is creating the log files and where? If you control the creation of the log files, save them somewhere that all users have read only access to. If not then things become really problematic here. 

First, sudo is not going to work for a non-admin account. It only works when you log into a session with admin credentials. Second, you would have to know the admin credentials first, before you could sudo. If this is for a commercial app then I think you are out of luck. 

I suppose you could ask the user for admin credentials, then use those creds to shell out and change the permissions of the log files in question but YIKES! Rather, you should change the permissions on the folder containing the log files. 

Other than that you will have to ask your end users to change the permissions themselves, or have an Administrator do it. Messy.
