Iπm running OS X (10.4.9) on a Dual 2 GHz PowerPC G5 with 512 MB DDR2 SDRAM.

Recently it has been failing to shut down completely. It closes all open windows, ends all running applications, etc. and then just hangs. The only way I can get it to power off or to restart is to press the power switch.

I thought maybe Iπd try repairing the boot disk, but I canπt get the computer to start up from a CD/DVD. It puts the silver Apple on the screen along with a few extraneous lines here and there, then just hangs.

Any ideas how to solve my problems? Thanks.

I would look at the system log to see what errors are posted there. It's possible an item in /Library/StartupItems/ is misbehaving.

That usually means you are booting from the wrong CD; specifically, you are attempting to boot from a CD that came with a different Mac. Are you absolutely sure the CD you are using is the one that came with that Mac?

I don't think the log will show anything helpful. But the likely culprits do indeed include evil StartupItems, as well as third-party Extensions (.kexts). Some people with this problem have reported that disabling MySQL helped. In my case when I had this, it was a thing in StartupItems. So one way to know is to eliminate things, force the restart, and see whether a restart now works. It may help to enable SSH into this machine, as it is possible that you could SSH into during the hung state (from another machine) and actually see what processes are still running.

Well I do.

But the likely culprits do indeed include evil StartupItems

...which would likely show up in the system log...

, as well as third-party Extensions (.kexts).

...which, can also show up in the system log if they are misbehaving...

Some people with this problem have reported that disabling MySQL helped.

Doing that without first determining MySQL is causing the problem is like repairing permissions to fix a networking problem. A smarter way to approach any problem is to figure out what's causing the problem first.

In my case when I had this, it was a thing in StartupItems.

The system log would likely have shown that one or more startup items was not loading correctly.

So one way to know is to eliminate things, force the restart, and see whether a restart now works.

Blindly doing so without first looking at the system log is one way to go, but I see no reason not to look, do you?

It may help to enable SSH
into this machine, as it is possible that you could SSH into during the hung state (from another machine) and actually see what processes are still running.

Good tip - the first thing I do on any Mac is enable Remote Login for this reason.

Jolly, the suggestions you and others offer would probably be helpful if I knew more about how my Mac and OS X work.

I did locate a number of Logs in my User folder and reviewed them all. But I don't understand any of them. Some are hundreds of lines long.

What if I were to simply clear them all and then go through the shut down process that hangs? I could then take another look at the Logs and see what's there. I could also try booting from the OS X disk that came with my computer and see what appears in the Logs.

Are there certain Logs that I should look at in particular?

I do appreciate any guidance you may wish to offer.

First, try to shut down your computer and let it fail to shut down. Then power it down and boot it back up again.

To view the system log:

1. Log into an administrator account.
2. Open /Applications/Utilities/Console.
3. From the Console menu bar, select File > Open System Log.

Feel free to copy this log and paste it into an email to jolly roger at pobox dot com.

My guess: you have an OWC drive and installed the freebie HD software coming with it. Am I guessing right? Get rid of it. /PaulN

Hi John,

I got your system log in email. I notice the following errors in the log:

SystemStarter[46]: The following StartupItems were not attempted due to failure of a required service:
SystemStarter[46]: /Library/StartupItems/QuickBackStartupItem SystemStarter[46]: /Library/StartupItems/SpeedToolsDTStartupItem

These startup items are apparently part of SpeedTools Utilities from Intech Software.

I recommend uninstalling that software. It's obviously the cause of your problems.

Agreed. That is exactly the rogue StartupItem I was referring to in my own answer. Nice analysis! m.

So my guess was correct. SpeedToolsDTStartupItem comes from OWC as freebie with HD purchase. Get rid of the whole package. /PaulN
