So I have a older Macbook that we use just for iTunes. It is running the 10.4.11 OS. I called Apple and they gave me a free upgrade to 10.5.6 OS. My question is, if I upgrade this OS, will I lose all my files, etc..Do I need to back it up before the upgrade? Thanks for the help.
I am going from my OS 10.4.11 to 10.5.6. The disk was sent direct from Apple to upgrade the OS. I need to upgrade the OS on the computer to upgrade to the new iTunes. It's just a computer we use for music.
