so u can give almost all administrator privileges without making the account administrator and the only thing that requires admin authentication is for installing certain things? im talking about tiger here, and how do u do this (make the standard account have alot of privileges)?
You don't have to do anything. When you try to install an application with a standard account, one of the following things happens:
1) If it is a file that is dragged and dropped to the Applications folder, you're asked for the user name and password of an admin (authenticate); if you are able to provide it, the software installs for all users. If you are not, it fails. The software can also be installed to the Applications folder inside the home directory without authenticating, but it can only be used by that user themselves.
2) If it is a file that uses an installer, it will either (depending on how it was designed / set up) ask you to authenticate, and then successfully install, or simply fail outright (in which case you actually have to log in as the admin user).
3) In very rare circumstances, installer packages will give you the option of installing it for the user only, which does not require authentication.
All of that is automatic for every standard account.
The difference for an admin account is that (1) requires no authentication; (2) may or may not require authentication (but the admin can use their own user name and password, while the standard cannot), depending on the circumstances.
