Mar 28, 2014 3:33 PM in response to Schuinby MrHoffman,Are you running OS X Server (the forum this question was posted in), or are you running OS X? If you're not sure what that difference is and why I'm asking it, then you're probably running OS X and are very likely not running OS X Server here.
Hopefully you have a pre-upgrade backup of your data, on the off chance something has either already gone badly wrong already, or if something goes wrong with the following...
To force the quit here and to force the shutdown here, press and hold the power button for ~10 seconds.
If you don't have a backup already and if the box doesn't reboot, then you'll want to boot from the 10.6 DVD (of OS X or OS X Server) and create a backup — it won't be a particularly good backup of the OS X or OS X Server system, but at least you'll have access to your own files and related data. This backup because recovering from a badly-failed upgrade might involve reinstalling OS X.
