Sony Support inform me about SxS drivers update in september :
Some good news the SxS driver will update this month so the SxS card will be able to be seen by Snow Leopard this would at least allow backup
or copying files on that OS all software is still on the schedule that I previously informed however at this time.

This is great news! Thanks for sharing.

Almost too tempting to load that SL disk that I have laying next to my Mac.
But I guess it´s best to wait for the actual update to happen

Please note there is some fix to be done also on XDCAM Transfert and maybe XDCAM EX Clip Browser and some others XDCAM utilities but i hope Sony fix them fast.
