The Mac OS X 10.4.10 update has nearly turned my Macbook into a brick. It crashes upon login and dumps me into a console. From there I can login with my user, but not much else. It seems that something called “SecurityAgent” is crashing upon login. I’ve tried every single tip I could find. Nothing seems to fix it.
Following various threads on the Apple Support pages I found many similar reports but no solution so far. The only way I can get anything useful out of it is:
# /sbin/mount -uw /
# sh /etc/rc
# open ~
That will dump me into some kind of stripped down Finder, where I can then launch “Dock.app” and “SystemUIServer.app”.
This is really horrible. Shame on you Apple. I’m eager to know when the fix is going to arrive. If this really requires a reinstall like mentioned in several threads, I could just as well switch to Vista since I don’t have really have anything that requires OS X.
