I just installed OS X 10.3 last night, and although everything seems to work ok I ran into a couple problems. The biggest problem is with Keychain. It refuses to let me create a new keychain, and when I open a program like Mail or iChat, it won't allow me to save my password, so I have to type it in every time. All it say is "error occured", but it won't explain what error has occured. Also, I've found that when I first start up the computer Mail crashes the first time I use it. The second time it's fine, though. I think this is also related to Keychain, in that Mail tried to retrieve the password for my email account, but whatever is wrong with Keychain caused it to mess up and quit. If anyone knows what to do with this problem, I would really appreciate it if you could reply to this thread ASAP. Thanks.
