MACLOVER You *might* still be able to install this update in a crude manner. Download the update manually and download pacifist. Install and open pacifist, drag the apple driver package to pacifist's window, and hit install. It should place the drivers in the correct areas, although with Aperture 2, a few folders may be different. If that is the case, you may want to extract the package to the desktop, then manually go through the folders, mirroring the folder exploration on the hard drive, then drag and drop to the correct folders.
