Does the login keychain have anything to do with the iTunes authorization required to play iTMS purchased music? If so, how do I reset the keychain without losing it? The problem is that every so often the login keychain pops up asking me to enter a password. I've changed it and the keychain did not so they are out of sync. The only solution I've found was to delete the keychain. In 10.4.11 there doesn't appear to be any other way to sync the login password with the keychain password. Furthermore as I do not remember my old dotmac password nor my iTunes Music Store password, and as I no longer have access to either the Music Store nor dotmac, I worry that reseting the Keychain would lose access to all the music I've purchased throughout the years, and that's a lot of money spent for me to lose it. The problems these brilliant people created are just so stupid I shutter to think what else they're messing up. I realize it's my fault for having to reset the password (even though it's a system bug in Mac OS X), but how do I resolve this problem?
