We use the following, when testing from a Makefile: sudo installer -tgt / -pkg foo.pkg

I don’t know how successful you might be in avoiding sudo…

The problem is that /usr/sbin/installer cannot be run from Objective-C code without a very crude hack. You basically have to embed Apple Script into your Objective-C code to be able to gain administrative privileges [1]. On Windows, there is the MSI library which has been part of Windows since Windows 2000 and it provides a clean and canonical access to the installer system [2]. Applications like Google Chrome use it to install their package updates in silent mode. I'm a bit surprised that Apple doesn't provide similar mechanisms. Adrian
