Re: auto-starting iMac

[kaye and geoff]

Hi all,

David Brown, who isn't on WAMUG but who has been following this thread, has 
suggested that the iMac might be set to auto re-start  on power failure. I 
haven't been into the new house, and I won't be going there today, but I'm 
certain he is right. I don't usually have that feature set, but the machine we 
are using is an old one, just set up to test that the NBN connection was 
working, and it could easily be set up that way.

It ties in with something else I noticed. The iMac shuts down quickly - 
noticeably quicker than the desktop machine I use at home. Because it is just a 
temporary setup there are no other devices attached, not even a backup disk, so 
there is nothing with a light to indicate that the shutdown is complete. When 
we're leaving the house I shut down the mac, turn off the modem, then flick the 
isolation switch as I walk out of the room. If the iMac is shutting down the 
screen well before it has completed its full power-down, I may be turning off 
the isolation switch while the iMac is still technically on (although it shows 
no sign of life).

When I want to use the machine I turn on the isolation switch, turn on the 
modem (or just walk over and wave my hand at it - takes the same amount of 
time) and lo and behold the iMac boot up - it has detected the return of power 
after what would have looked like a power failure. I've never had a pop-up 
warning me that the machine was shut down incorrectly.

It even allows for the fact that I've turned on the power, avoided the modem,  
and the iMac hasn't booted - if it had time to fully shut down last time it was 
used it wouldn't have re-started. 

I'll check it out next time I'm in at the house and let you know.

[Philippe Chaperon]

Hi Kaye and All, 

Though I do not see how my suggestion further down can help in your case, but 
you could ask your electrician to ensure that the power plug in which your 
computer is connected is properly wired. If the return or neutral cable is 
incorrectly connected to the on/off switch, if you have one, it is quite 
possible that the computer would be continually connected to the live 240V 
wire. 

A proper and safe connection is for the ‘live’ wire to be cut off by the 
‘on/off’ switch, then any equipment connected to the plug would not be exposed 
to the 240V live at all times. 

Would that explain your ‘spooky’ booting up of the iMac, I am not sure but its 
worth checking. 

Wishing you all the best, and if not resolved I may be able to get you an 
exorcist … 

Good night, 

Philippe Chaperon

Also try an SMC reset. On the iMac, this is to shut it down, unplug all the

is plugged in. Leave it off for a few minutes, then plug things back in and 
start it up again. This will reset the Power Management etc. Incase there’s 
something “playing up” there.

Try those two things and see if it helps.

Oh, and another thing to check. Do you have any devices in System Preferences - 
Bluetooth that aren’t being used. I once had a rogue bluetooth keyboard that 
was in a cupboard that did strange things to a computer as it was still on and

Yes Kaye, time to experiment. Can you connect via WiFi?
If you connect via Wi-Fi plug the cable into UNI-D1

Yes - the modem is plugged directly into the NBN termination box. The modem is 
off - no lights showing at all. The only connection between the modem and the 
iMac is the ethernet cable (as I said, they are even on different power 
circuits), and the the modem and computer are about 1.5 metres apart. This is a 
temporary setup in an otherwise bare computer room.

 

To be honest, in more the 50 years of computing I've never seen anything like 
it. When it was just the computer booting when I turned the modem on I was 
prepared to accept that there may have been an effect, but with the modem off, 
it is quite spooky.

> Are you very sure that the iMac does shut down completely?

Absolutely. The room's isolation switch is turned off before we leave the site 
- it has no power going to it. The modem is on a separate power circuit that 
stays on, but the modem itself is definitely off.

I come into the house, turn on the room's isolation switch, then do my magic 
hand wave near the modem and the iMac (but not the modem) turns on, with a 
satisfying "boing".

The floor is solid concrete with tiles - no vibrations, and not even carpet to 
spark up static. It is truly inexplicable.

Hi Peter and Neil,

> Bizarre is all I can think of. What brand/model is the modem? 

Standard Netcomm modem, straight from Aussie Broadband. The house is brand new 
- not even finished, and I not only turn everything off, I have a power 
isolating switch on the computer room and that is also switched off when we 
aren't there. 

We are completely charmed by it - makes a good show if someone else is there 
working on the place - we can just wave a hand and the iMac boots up. The modem 
isn't so obliging.

I have been known to make (old-fashioned large) printers spew out paper when I 
walk up to them - I definitely store a static charge strong enough to affect 
electrical devices, but I've never actually turned one on before, and Geoff has 
never had static issues.

Re: auto-starting iMac

[Neil Houghton]

Hi Kaye,

 

Not sure it is relevant but I often notice my iMac waking from sleep when I 
enter the room.

 

Whilst it is nice to imagine I have such a commanding presence that even 
inanimate objects feel compelled to acknowledge my entry, I suspect the reason 
is more mundane ;o)

 

Our old house dates from Victorian times and there is a certain amount of 
bounce & movement in the floorboards – I suspect my entry into the room results 
in some vibration/movement at the desk which is recognised as a movement of the 
mouse sufficient to awake from sleep. However, I have never been sufficiently 
interested to try & prove my hypothesis!

 

If your “problem” was caused by something like this it wouldn’t matter whether 
you were close to the modem, but not the iMac, but rather whether your approach 
to the modem resulted in some “vibration” over by the mouse.

 

Of course this is drawing a VERY long bow – and would only even be relevant if 
the iMac is just waking up from sleep.

 

If you have actually totally shut down the iMac and it is doing a complete 
bootup from cold – well – do you know any exorcists?

 

 

Cheers

 

 

 

Neil

Hi,

 

This isn't a problem, but a rather puzzling behaviour from my iMac. We have 
recently connected the NBN to a house we are building, so I have the modem and 
an old (~2007) iMac in the house, connected by ethernet. Because we aren't 
living there I turn both computer and modem off most of the time.

 

Right from the start I noticed that if I turned the modem on first the iMac 
booted itself up without being touched. OK, I can accept that. But one day I 
reached out to turn on the modem, changed my mind and didn't touch it, but the 
iMac booted anyway. The next time I was on site I tried an experiment, and just

It does seem to be associated with the modem - I can go to the desk and sit in

Any ideas?
