Thank you Neville Hillyer!MadMac0 had already told me abt CCC, but I hesitated. It took me a while to learn it all; but I succeeded in re-installing only what I wanted. The only problem I have is with the ITunes. It's NOT working at all. I asked to import the whole folder (as I did with images and movies); but when I tried to open iTunes, it got the window-msg :
< the files "iTunes Library.itl " cannot be read because it was created by a newer version of iTunes. >
I can't understand it, because I only started docs importation after updating the iMac and verifying it was 5.8. I'm sure it's better updated than it was before when I couldn't updated properly. I went to toolbar>apple>Sofwareupdate - everth was correctly updated. Shouldn't it include iTunes? Why then, am I getting this msg? And the solutions?
