    Hello I have maybe stupid question. When I install new version of MAC OSX on my MBP do I have to backup and reinstall all my applications including bootcamp and Windows? Or it is like any other update of the system that leaves my data and applications intact?

    Cheers Milan

    You should make a back up of your important files in case something should go wrong. But if everything goes right, all your stuff will be there after the update.
