The Mirror widget has acted as a quick fix for the cpu whine. Unfortunately with the keyboard update it doesn't work anymore. IOUSBFamily.kext gets updated and that's it for the Mirror fix. However if you can rollback to the earlier version it works again...ver 2.4.6 I THINK. I saw this posted somewhere else. The only version I could find I downloaded but it seems that it's corrupted. Anyone know where I can get a copy? Thanks!
