My KeyChain (I think) is being really stubborn. Basically, I sync'd all the stuff on my iMac to MobileMe, and sync'd it again on my new MacBook, as I wanted to transfer most of the stuff over. Anyway, I noticed something odd. On the iMac, if I go into the MobileMe preferences, it throws up about 8 keychain errors then shows the MobileMe page, but logged out. I'm not too fussed about this as I'm selling the iMac soon anyway. However, on the MacBook it shows the preferences fine, but, stuff like Transmit and Adium aren't saving their passwords, which means I have to re-enter them every time I login to Adium or use Transmit. Which is irritating. But for some reason, it's working without any issues in apps like Skitch. So, is there some kind of way to reset the entire keychain or something? Could I just delete all the entries in the "login" section in the Keychain app, and, if so, would that screw anything up? I'm not fussed about having to re-enter all my passwords (there aren't that many entries there anyway), but I don't want to totally screw up OS X. Would that work? And, of course, if this is being caused by something totally different please do tell. Thanks in advance for any help.
