MacPro hangs when restart/shut-down.... help/info please..

Question

Hello. I have a Mac Pro 3.0GHz. The problem I am having is that when I go to shut down, the system hangs for apx 3-5 minutes before rebooting/shutting down. How can I find out if there is a process that is causing this or if it is something else? The finder shuts down and the background remains on the screen during this time. The only way to speed the process is to hold the power button for 5 sec and kill the machine. The machine never used to do this. I want the system to reboot immediately like it used to.
Help / information appreciated.
Thanks,
Scott - n0nuf

Answer 1

When there is a thread of 50+ users (which often means, with multiple postings from each, 100s of messages) that may get our attention.
A few, even half a dozen is not many, or a lot.
Anyone who has ever done any testing, or had to isolate a problem, controls for variables, rules out 3rd party hardware and software.
These forums are user to user. Was it 10 yrs ago when they first started that there were Apple mods and replies that had Apple's logo? no longer.
Yes, there is a way to find out what causes an "A + B = C" to occur.
And that is why it takes 1000s of beta testers, too.
As for grain of salt, I'm biased. I think we all try to keep discussions focused and with as much in reality-based known fixes and help. Any help though often has to follow from a fresh system and careful observation, and then taking notes, and not making changes for a few days with each step.
I would look for something in your system, but not in stock hardware or from Apple software though.
