No one was more excited to get to know their personal computer as i was with my mac. I love that thing! Then came the data transfer from my Suunto Cobra to the Mac OSX. it took several months of playing around with programs to finally find one that will work correctly. MacDive is a great program that conveys all the information and graphs i could want. There customer support was quick in email responses and i couldnt complain. I asked several divers and shops for help in this matter and they all looked at me as if i had asked them to give me 1000$... needless to say i am happy with the product and even more happy that i can finally pull my dives from my computer. If anyone has a mac computer, MacDive is a great option to use. There are still some kinks i am working out, but i wrote this in case any of you have this problem or know someone who does. It can get tricky to set everything up, but it works! If anyone knows how to erase the Cobras memory, let me know!
