I am typing this from one of the few programs that still run on my PB... Can't start anything but what is in my dock. A few events leading up to this situation: Performed the security update (5XII03) Simultaneously performed Soundtrack update (both from system preferences software updater) During cleanup: Put my crashed iPod in its cradle (stuck continuously restarting from the Apple logo after running completely out of juice) Result: Big gray square appeared on screen, telling me in several different languages: a serious error has occured, restart computer by pressing the power button for 5 secs or press restart button. After restart: Computer restarts fine Login is ok Some startup programs launch fine (ms messenger) Classic tries to launch: requester appears telling me classic is not recommended on machines with less than 128Mb ram (i have 512, 'About this Mac' reports correct amount), does not continue launching (doesn't matter wether i click quit or continue) I can navigate the programs that are running, can navigate the dock, can start Safari, preferences,... From those programs i can choose file open, navigate my disks,... contents seem fine. CAN NOT: Launch Finder Do anything on desktop (nothing is there anyway) Open trash (which is essentially a finder window...) Launch some preference components (update, notably) Am stuck. Seek help. Anyone have a clue? Specifically, Anyone have tips on: How to start a console session How to start utilities not in dock Any help greatly appreciated, Abe.
