Hi All, I am new to Mac and seem to have an ongoing issue. When ever i connect a SD Card to my MacBook Pro 13" with the built in SD reader. And then move files around etc. I am unable to move to a windows platform computer and view these files. Would this be something i am doing wrong? Do i need to delete the files (hidden files) that mac creates on the memory card? Im lost completly with this now...any ideas.. i no its not the card cos i have bought several new cards Thanks in advance Martin F.
