Progress, not a bit.

However you might have helped. Some people have had Firewire problems after upgrading. To fix it they install the Firewire Kexts from their earlier installation.

I tried installing the FW kexts from 10.4.9 but that didn't do anything for me. Maybe I have a different problem.

But that doesn't mean reverting to earlier kexts won't help you. Try this thread for a guide http://www.insanelymac.com/forum/ind...owtopic=133426

Let me know if that helps...and ya know, if anyone can help me...
