Thanks, Milton - the 10.9 stuff is good information.  I'll try and stay away from testing with 10.9 if at all possible.

As other have indicated, Mavericks seems to work for them. However I and other people have had odd pauses erratically with it - where it will beach ball delay for up to 20 seconds sporadically - regardless of what application your in. I have no idea why it does that and nothing shows up in Terminal as to what is the root cause.

Before the firewire bandwidth issue suddenly cropped up, we were running both cameras simultaneously at full resolution and bit depth and never had a problem.  I'll also try resetting the PRAM again.  I'm assuming it's not either one of the cameras, because they work fine individually, just not when they're both connected.  Although, when they are both connected, it's always the same camera that's recognized, while the other one is ignored.  I can't even run them both at the lowest resolution, bit depth, and frame rate - I think.

That could be a Hub issue too.

Have you tried connecting the Flea 3 cameras to each other in Daisy Chain fashion (i.e MAC -> FW 800 to First Camera -> FW 800 port on First Camera to Second Camera)?

It might not be practical for each camera on a separate telescope, but it would be useful for trouble shooting.

And you are using a FW 800 hub to your FW 800 Mini Port, right?

HTH..
