I've been having firewire sync and random audio dropout problems between my Presonus 16.4.2 and MacBook Pro often related to when another device on the same electrical circuit is turned on (confirmed many times).
I was using a Lacie flat cable http://www.lacie.com/products/product.htm?id=10346 so figured should be good quality. However, I today went an bought a Belkin 9pin to 6pin 800/400 cable from the Mac store and problem solved!!! I can power on my Rode Mic power supply, turn on lights & other devices and my audio keeps running. WOOOHOOO!!!
FYI - my particular issue is not Presonus specific - I just happen to discover it using the 16.4.2 - if i use the same test case and swap out the 16.4.2 for a Motu 896 I get exactly the same results.
So the moral of the story is BUY A NEW FIREWIRE CABLE - even if you own one that is supposedly good quality
I've been having the same dropout problems when my MacBook is connected to my 16.4.2, but in a live context, which is pretty disasterous! I play in a pub duo and use Ableton to play our backing tracks via FW into the Studio-Live (the desk is effectively acting as the Mac's soundcard). The dropouts are sporadic, although some have coincided with other devices being plugged in or turned on. I'm gonna try out a Mac Store FW cable and see how I fare out . Another thing about the dropouts is that they come in pairs with an interval of about 1 second between each drop-out ..it's damn annoying and embarrassing when it happens on a gig!

My advice and suggestions should never be considered advice or suggestions. These are mostly insane ramblings of a poor aircraft mechanic who can, strangely enough, still hear.
