I have a brand new Macbook pro. Three weeks old. I have tried to download my photos from my Extreme Pro 90MB/s Sandisk card but the computer doesn't recognize the USB reader. If I change the card and I put a cheap CF card the computer reads it without any problem. I have tried with both 8GB and 16GB CF cards. My pc and my older mac reads the high speed CF card but not the latest MacBook Pro. I am wedding photographer and I use professional grade high speed CF cards. I think it is a big joke if the Macbook "PRO" wouldn't read professional grade Cf cards. I have tried everything. The macbook pro only likes the cheap cf cards. I guess the macbook is not really a "PRO"! I bought the computer for destination weddings to back up and view photos after the wedding day but so far it is totally useless for me!!! What's going on??? HELP!
