First time posting.


I am looking at getting my Macbook 13" software updated and was wondering a few things. First is it possible and second what should I do beforehand/after install?


I have a 2008-2009 model white Macbook 13". The current software is version 10.5.8. I realize I will have to update to, snow leopard?, first and then I should be able to update to Lion.


  Model Name:MacBook
  Model Identifier:MacBook4,1
  Processor Name:Intel Core 2 Duo
  Processor Speed:2.4 GHz
  Number Of Processors:1
  Total Number Of Cores:2
  L2 Cache:3 MB
  Memory:2 GB
  Bus Speed:800 MHz

Those are the specs. I just want to make sure that the upgrade will be possible. I have a friend who works in a computer shop and says he can do the update for me so getting software won't be an issue.


Second part though is I need to know what to do before he updates the software. Will I have to do a full backup onto my external hard drive? Or can I get away with just backing up the important stuff like pictures, movies, important documents? Will the update completely wipe the hard drive and delete everything? Also, how should I back up the information? I don't really feel like spending money on a back up program if possible. Would something like Time Machine be decent enough to use? And finally, if I have to do the back-up and the software update works well, how to I re-install everything from back-up? Will it re-install the old software if I re-load everything?


Sorry for so many questions, I just want to make sure I do everything right so I don't lose any important information.
