HELP!! I am new to Macs. I am replacing and old Dell PC Laptop with this awesome Macbook Pro but I can't figure out how I can upload the files that I saved on my new WD My Passport 1TB external drive onto my new Mac. With the PC it automatically loaded "WD Smartware" onto my computer but it didn't load it onto my Mac. HELP! How can I upload and use all of the music, MS Word, PPT, Exel and photo files onto my new Mac?
