Hi there Apologies for the dedicated thread but I can't seem to find this particular issue in another thread and posting it in the 10.5.8 update discussion is unlikely to get me anywhere. I'm currently updating my workplace Mac Pro to 10.5.8... the update is currently sitting at "Patching Files" and hasn't progressed any further for over half an hour. The update isn't locked up in any way, there's no beachball, and the screens black out after 10 minutes or so of no mouse input, but nothing else is happening. Is there anything I can do other than waiting it out? I'm pretty sure that yanking the power is going to do more harm than good... Any help would be much appreciated. Thanks!
