I have continuously had a problem updating 4.0 with the various updaters. I get about 25% through the patch when a dialog comes up: "An update error prevented the update from completing. Updater error Logic Audio Mac 4.1.1. 110002: 2, -15 The only way around this seems to be to start all the way from 4.0, with a fresh install from CD, and update incrementally. This happens with all extensions off too. Please advise. Neil Goldstein
