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

Hi Kaye

Though it shouldn’t really affect it when it’s “off”, but a couple fo things to 
try/check - 
In System Preference - Energy Saver. Untick “Wake for Network access”. If it is 
ticked.

Also try an SMC reset. On the iMac, this is to shut it down, unplug all the 
cables including the power cable from the back of the iMac. So nothing at all 
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 
connected, but no longer used. Removing it from Bluetooth resolved a lot of 
“weird happenings”.

Just a few thoughts before you go in a ghost remover :)
Kind regards
Daniel
