MacInTouch: timely news and tips about the Apple Macintosh10.4.9 works very well. I also read on Macintouch that the new iTunes is troublesome as well.
.... I've just gotten off the phone with Apple support and they've confirmed that the 10.4.10 update is buggy, and another update is in the works.
...The tech I spoke with recommended that I archive-install 10.4.6 and update only to 10.4.9 using the manually downloaded updaters on Apple's web site.
No rush, I'll check back in a couple of week and check Apple's forums before the update. Maybe I'll hold off on all Apple updates until they get out of the primary iPhone blitz...
Update 6/30/07: More on Mac OS X Hints Not a great update! Mac OS X Hints is probably a good place to visit one week after a major update, and prior to applying the update.
