For some reason Apple hasn't posted this update yet (it was released in Oct.) It's only available via CD that ships with new Time Capsules and Extremes. I bought an Extreme about a month ago and dumped the CD. Now I find that since updating to a new iMac running Snow Leopard I have to have version 5.5 of the utility. Would someone mind hosting the app for me? I would greatly appreciate it.
