I have a Power Mac with OS X 10.2 on it with a bunch of software that i dont have the discs for anymore. I want to upgrade to 10.4, will i lose my software/have to reinstall it, or will it still be there to use after the installation?
You might have to reinstall some programs - generally ones that were installed using a .pkg installer you'll have to reinstall because root files and stuff won't be there.
