Looking for some help. I bought a 24 iMac a few weeks ago, and on 1 April, I started having issues. The Mail application, VLC player, Yahoo IM, and iChat all disappeared. I have reinstalled all since then, and they seem to be working fine, but I would like to know what caused it so I can prevent it from happening again. I had Apple support call me for the problem initially, and their rep said it could have been a bad software load (which seems odd since 2 of the 4 apps come loaded with the Mac) or hardware incompatibility (which seems odd for the same reason). If anyone has any ideas or suggestions please let me know. I guess I can also add that when I updated to the newest iTunes it wouldn't open back up. I tried booting with a new library and had the same problem, so it wasn't a corrupted library. I tried reloading the previous version, same problem, upgraded again same problem. I installed iTunes 7.7, same problem, but when I updated from there it worked. I don't know if these are common or separate from each other, but worth noting.
