I am thinking about buying the canon rebel xsi this week, and I wanted to see if it is Mac compatible. This might be a really dumb question, I am new to owning my own DSLR. I have a new-ish macbook pro, I just bought it the end of July. It has an SD card reader built in... does that mean I don't need a card reader? Also, I am pretty sure that the rebel comes with a cord to hook it up to the computer- should everything be easy-peasy with my mac? Last question (for now!): What software should I buy? Can I edit my pics in iphoto like i do my regular digi cam? Thank you so much for any help/advice!
