I did finally update to 10.2.1, but I'm still getting the error message when trying to update with the combo. I'm on dialup here, so nearly 60 megs is nothing but trouble. And I don't like using the Software Update because if you ever have to format, another big download is required. Any other help? Thanks Tomac. I really like the Pismo. OSX is a dandy, too. Hey, why not just stay in 10.2.1 until 10.2.4 comes out?
