I'm running OS X 10.4.11 on a MacBook Pro (previous model). I want to upgrade to 10.5.6.
Could someone please explain how this will affect my computer? Will it delete all my applications, media, preferences, etc.? What should I back up, in that case, on an external hard drive?
Forgive my ignorance, but this is the first time I've upgraded an OS. I usually just buy a new laptop...
