I want someone to be able to install software on the Mac but not be able to change other passwords. So ideally for software install purposes, that user could enter their own username/password for authentication. But they would not have the usual admin privileges which could cause problems.
I am not trying to get around the admin requirement for software installs, just limit that admin's privileges.
Does anyone know a hack that would allow me to create an admin account that either
1. Can install software, but be a standard user in every other way; or
2. Do everything except manage other accounts.
Preferably, #1. I know that this would have to be a hack which requires modifying files or permissions on the command line. I'm comfortable with that. And, I back up every night :-)
