Bug? Max 6.1.2 64 bit as ReWire client in Logic 64 bit

Yes it's ReWire blues. Your help is appreciated!
OSx 10.8.3
Max 6.1.2 in 64 bit mode
Logic 9.1.8 in 64 bit mode
My goal is to get [transport] sync'd to Logic*
When I use Max 6.0.8 and Logic 9.1.8 in 32 bit mode I see Max as a rewire client in the Logic Library
Not so with Max 6.1.2 and Logic 9.1.8 in 64 bit mode. 64 bit mode is essential for this project....
Max says: "Registered Max 6 ReWire Device Please restart your ReWire mixer application" when ad-rewire is selected
But on any combination of starting Max and Logic Max says "ad_rewire: error starting audio. Is ReWire mixer running?"
I have tried:
Reinstalling Rewire
Reinstalling Max
Getting rid of all older Max versions
Trashing Library/Application Support/Propellerhead Software/Rewire
deleting and reinstalling Max 6.1.2
Deleting files in ~/Library/Application Support/Cycling '74 and deleting and reinstalling Max
Putting MSPReWireDevice.bundle in Library/Application Support/Propellerhead Software/Rewire
Removing MSPReWireDevice.bundle from Library/Application Support/Propellerhead Software/Rewire
Deleting and re-reinstalling Max 6.1.2
Opening Reason hoping this would "inspire" Max or Logic
And all kinds of other stuff. Reason will open in "ReWire Slave Mode," just can't get Max to show up as a Logic ReWire client
Ideas?

*I can get MTC via a combination of [midiin] and [sysexin] and MIDI rt via [rtin] into Max from Logic no problem. I seek detailed (timesig, tempo change, maybe basic start/stop/pause/continue commands via [hostcontrol~] and higher ppq) transport info that Logic's MIDI clock (at 24 ticks per beat) cannot provide. When functioning with Max 6.0.8 and Logic 9.1.8 in 32 bit mode [transport] with @clocksource rewire was matching Max at 480 ppq, and providing good tracking through tempo changes etc. I have considered workarounds using [rtin] but tempo changes are a problem.
