Hi,
I connected today my Aptus 65 to Snow Leopard, which run on my new Macbook Pro (latest model "5,2" June 2009), for the first time.
The digital back is NOT recognized by the new Mac OS 10.6.
As the result the Aptus 65 cannot work tethered with the new Leaf Capture 11.2.9.
The memory card in the digital back can be read in Snow Leopard without any problem when connected via a card reader, not via the Aptus. So, it's the Aptus problem.
The Aptus back does work with older Leopard 10.5.8, I tested this connection today with another Mac computer.
Please note, in October 2009 I sent my Aptus 65 to Kodak Israel for service under warranty and received it back a week or two ago. Kodak reps said the back is in like new condition, perfect, perfect...
But why the Aptus 65 cannot connect to Snow Leopard?
(at such times I think to change platform, never had any issues with Nikon)
If your back works on another computer then it is not likely a back hardware issue, so you should try and isolate the problem:
Do other FireWire 400 devices connect to this specific Mac without issues?
What cable is used to connect the back? Is that the same cable that was tested on the other machine? Are any adapters being used and if so which ones?
Is the Mac running on mains power or on its own battery?
When you connect it to the Mac, does the orange light come on? Do you hear the fan spinning? Do you see it in the Apple System Profiler?
Was 10.6 put on as a fresh install or an update from 10.5?
If the latter, was 11.2.9 installed after the update?
If 11.2.9 was installed AFTER 10.6, did it ask you to restart the Mac?
If not, I would suggest to re-install 11.2.9, re-start the Mac, remove any FW devices and the CF card. Then launch 11.2.9 and plug the back in. Do not press any button, just wait a few seconds and see if it initiates to connection or if it brings up an error message.
BTW when you say card reader is that USB or FW?
