Hey Guys... I have some really basic questions that I need to figure out before I loose irreplaceable stuff. 1. I would like to upgrade my MacBookPro to Snowlepord. I have the CD and all the instruction so with that I think I am set. 2. In case I will do that, what should I do so my iPhoto library will remain the same with all the event and all the albums? Where should I save it and in what way? Do I really need to open different libraries and save them separately? or I should retrieve it from TimeMachine? If so, would it work although I am upgrading my iLife as well? 3. Same as for number 2 just with iTunes? 4. What should I do with all my applications, again I will format my computer. Should I save them in a regular external HD or should I retrieve them from TimeMachine? would I need all the passwords for them? if yes, how can I avoid it? I hope you can help me guys. I really want to upgrade and I am afraid I will actually make my environment less, since I will loose so much. Have this project that needs to be done. I really appreciate your help.
