No. Our product does not support 10.6 yet but we are in the process
of porting the driver to 64 bit 10.6. We actually thought it would work in
32 bit snow leopard but it does not seem possible.

Our driver does not use any 64 bit data types and we thought a simple
recompilation would suffice but NO, thanks to the new interface.

We have not tried the upgrade from 10.5 to 10.6 with the old 10.5 drivers
because our primary interest is 64 bit 10.6 and we know the 32 bit driver will
not work. I would like to get quick answer from you folks so we can
save some time.

Thanks.

Tony,

Have you tried it yet?

I just found out that the read/write interface for the IOStorage class is
not compatible in 10.6. There is a new attr argument and the completion
object is not passed as a pointer.

It is trivial to port it BUT

if the customer upgrades from 10.5 to 10.6 and they have some IO filter
drivers, are they going to have major problem??

How would they know which driver they have to upgrade?

Please share your ideas.
