I have a White Macbook that I bought 4 years ago, and just recently I upgraded to OSX Lion 10.7.2. I have a Nikon d5100 DSLR, and it connected via USB just fine when I was running snow leopard. Since the upgrade to Lion, I cannot connect the camera, as it isn't found on my computer. Iphoto does not recognize it, Image capture is no where to be found on my computer. When I connect it to my friend's computer running snow leopard (newer macbook pro), it connects, is recognized, and imports photos fine. SOMEONEEEE HELLLLLP MEEEEEE. I don't want to downgrade back to snow leopard, and I would love to use my thousand dollar camera lol.
