Won't Shut Down! - iMac 800 G3 - TIGER OS X.4

Hello,
I have an iMac 800 G3 17" flowerpot.... 768MB RAM... and I just installed Tiger OS X.4.1 ... and now it won't shut down.

It runs beautifully... but just hangs on shut down.

It will even go to sleep after 15 mins during shut-down, and wake up.... but it never, never fully shuts down... just hangs at the blue-screen.

What can I do to fix this?

TIA!!!!

First we'd like to know what Mac you have.

Will it shut down if you start it without Startup items?

Cheers

Oh dear.

Nasty.

Some process won't die..

If you run up a terminal
and get a root login via

sudo bash

and type

sync

then

halt

that should thump it down quick and hard, whilst preserving the filesystem.

Then try a reboot via the power switch etc. If it doesn't come up cleanly, and shut down cleanly there is more work to do.

It may be that you have got a weirded out filesystem..but lets try the easy things first.

At least it seems to BOOT.

TIA!!!!

You might go to the Apple web site and look for instructions for re-setting the PMU or SMU, I think an iMac of your vintage will have the former not the latter. For different models this happens in different ways.

Usually the cause of this is a misbehaving item in the /Library/StartupItems folder. What do you have in there right now?

Apply rot13 to this e-mail address before using it.

Ditto...... I had the same issue some time back with this G4-AGP 1GHz and as I recall there was something checked in my StartUp list that would wake up the machine from a shut down.

I found it really weird to Shut Down the Mac and come back 30 minutes later and find it running.

I don't recall how I fixed it but think Andreas made an excellent suggestion.

Hold down the SHIFT key while booting.
Then try shutdown again.

If it does shut down properly, then it's likely something in your startup items.

There's no such machine.

All iMac G3s had 15" screens.

You may be referring to an iMac _G4_.

installed Tiger OS X.4.1 ... and now it won't shut down.

I doubt that Tiger had much to do with it. I suspect that Something Else(tm) installed, usually as a startup item, has everything to do with it.

It runs beautifully... but just hangs on shut down.

Is the pinwheel going?

Have you (the OP) installed applejack (from versiontracker.com) and run it? I will bet that if there is some basic problem, this will fix it - or at least tell you that it is a conflict from somewhere else.

Nonexistent group comp.sys.mac.hardware deleted from ngs.

Mm. I had this happen - nasty program wouldn't close..

Stage one is close all apps that you can.

Stage two is to use the activity monitor to see if some of 'your processes' haven't died.

Try 'force quit' on them ..from acivity monitor.

If that doesn't work, the following won't do any harm.

Fire up a terminal
Execute:-

sudo bash

which will give you a superuser privileged shell.

Then execute these two commands:-

sync
halt

This will synchrnise the file system and pull the rug out from under the machine.

If it still does the same after rebooting, its time to look at the logs and figure out why.
