Many thanks. I have uninstalled the SxS driver and now the P2 card appears all the time. Problem solved. When using the Mac Book Pro in the field in the future with a client wanting SxS system, do you think uninstalling the P2 drivers and reinstalling the SxS drivers is feasible? I assume regular swapping of the two systems’ drivers wouldnt be advisable for the mac.
Thank you for your replies.
