So all of a sudden, my iTunes wouldn't run, and it told me that I didn't have the most current version of OS X. I figured I needed to run system update, etc, but came to find out I have 10.4.8 and there were no more updates. Later on, I tried to install a new program, and it tolded me the minimum requirement was 10.3.9, so it wouldn't install. I'm confused now because I have a higher version. I've also noticed that all my pictures will only open in graphic converter and when I try to change which program they are opened in it automatically goes back to graphic converter. Some of this kind of sounded like the loop-a virus/trojan/whatev, but I never opened a file like the one it said you needed to in order to get it. Any ideas? I called a mac technician and he was at a loss.
