Power off message in iMac
It has happened twice that a black screen shows saying to power off the iMac by pressing and holding the power button. I happens right after I log in.
What could this be? Anyone has had this problem? Other than that, the iMac is working properly, is fairly new.
Thanks
Something on your kit is causing a kernel panic. It could be caused by software that you installed or even a peripheral that you have attached.

Can my USB Drive be configured to power off when the iMac is powered off?
I am using a Lacie 500GB external USB drive. The drive remains powered on when my iMac is powered off. Is there any way to have the drive automatically power off?
Hello Jack
The s.o.p. for shutdown should be to eject the drive, turn it off then shutdown the iMac. The s.o.p for startup should be to startup the iMac then turn on the external HD. Many external HD manufactures do support a sleep function that allows the drive to sleep when the iMac is sleeping.

I just downloaded the OS Mavericks onto my iMac. Now all of my imessages on my iphone are also showing up on my iMac. i do not want this. My son may accidently see adult conversations. How do I turn this off on my imac?
Hi,
As Frank Says you can disable the iPhone Number in the iMessages settings on the Mac.
You can remove the Apple ID from the iPhone.
If you want a deeper reset than that so that the iPhone Number does not even show on the Mac's iMessages settings you can do this:-
Access ~/Library/Preferences.
Find the com.apple.ids.service.com.apple.madrid.plist file.
Drag it to the Trash then restart Messages.
You will have to re-add the Apple ID.
At this point if you have not removed the Apple ID on the iPhone (or other device) then you will have to Refuse/Dismiss the pop ups that tell you what the iPhone is using.
You will receive periodic prompts on this from now on unless you remove the Apple ID from the iPhone.
If you want totally private messages on the iPhone you will need to use it with Number only.

Every once and awhile, a black error message box appears on my Macbook screen that says I need to power off and restart my mac. It is in several languages. I can't do anything until I power off and restart. Restarting brings my back to where I was.
Why does this happen?
Thanks for any information.
DennyYou were correct, I was looking in the user report. Here is the system crash report

Power off after putting iMac to Sleep
Have you ever experienced this?
Put you iMac to Sleep and it powers down - not a shut down, but the power goes off - no blinking light, no whirring of the hard drive, no sign of life!
I have read and performed many of the tips regarding NVRAM, SMU, PMU, etc. resets. None have worked.
Situation 1-
Use the 'sleep' command - moments after the machine powers off.
Situation 2 -
iMac screen saver will run for a short time, then screen goes blank, the power light illuminates, the fan spins full speed, and the machine is totally unresponsive to mice clicks or movements, or keyboard entries.
Situation 3 -
Sometimes upon power up, the iMac doesn't start, but you can hear a faint buzz sound from the back of the machine. Similar to audio hum.
These problems occur whether or not other devices are connected to the iMac.
Connections-
Standard USB devices - mice, card reader,
Bluetooth keyboard
Ehternet
Power Settings-
Screen saver 5 minutes
Energy Saver - to sleep when inactive - 15 minutes, display to sleep - 15 minutes.
Various other settings tried with no change in problem.
I suspect the power supply. What's your opinion?

I began experiencing the same thing this week (two days ago). I also tried repairing permissions, resetting SMU, and removing the iTunes receipts (Library/Receipts) since this is what caused an earlier failure to sleep. The difference is then the computer would not sleep, now it shuts off instead of sleeping.
Situation 2 -

you can hear a faint buzz sound from the back of the
machine. Similar to audio hum.
I have experienced this (Sit 3) as well with my LaCie firewire drive connected, sometimes. I have found that powering off the LaCie resolves this, as does unplugging it.

"slide to power off" notice keeps appearing
iPad Mini: "Slide to power off" notice keeps appearing. Fully charged. Restored to original settings and then restored from backup ok.
How do I get this notice to stop popping up, please?
Thx.
DanProblem solved.
Turns out that evidently the iPad Mini was dropped and the clear shell case for the back came off. It must have been put back on backwards so the On/Off Sleep/Wake button was being pressed by the case when held tightly... causing the "Slide to Power Off" message to show. This was discovered when the Smart Cover wouldn't stand the unit properly... But.. only after I guessed the Smart Cover was broken and I bought a new Smart Cover. The new red Smart cover didn't work any better than the previous blue one. Soooooo... I looked carefully at the unit and found that the clear back had been put on backwards!
Now, how do I turn this into a positive "teaching moment" with my spouse? Or, maybe after 53 years of marriage I'll just take credit for fixing it and getting her a beautiful new red cover!
Thanks for your help.

Recomended External HD FW800 with power-off/sleep feature
Hi.
After "googling" some hours, I dont want to miss asking here before I spend more money, beacuse i could skip any model or so... Any recomendations (based on knowlage or experience) of brand/model to buy for an external HD with this kind of features:
- FireWire 800 port (does 800 give 400 compatibility?)
- supports 1Tb or some more
- power´s/off/on when I power-off/on my iMac, or if it sleeps.
-last, not so important but cool, could include some USB/firewire Hub feature too.
thanx
vcostaI have to agree with the previous poster, the LaCie Quadra D2 are good drives. I have 3 (320, 500 & 750 GB) daisy chained together connected via FireWire 800 so far they are running fine. However others really like OWC Mercury series too. You can find those at:

Hi all,
I have now for a couple of days Kernel Panics and auto power off of my iMac G5!
I have experienced KP in several occasions. Notably (can be reproduced) in iPhoto when I try to order prints online. The dialogue box pops up and then after 10 sec I have a KP!
Also some KP when viewing clips with Quicktime (wmv with Flip4Mac as well as plain mov files!).
Note that my software is up-to-date. I re-applied the combo Mac OSX 10.4.8 but that did not help.
I did reset the MPU and now I even have the iMac powering off (actually crashing badly).
For info, I have experienced KP at sleep mode since day 1! I rally fear an hardware issue.
Question: how can I trouble-shoot Kernel Panics?
PS: I have rebuilt the authorizations, no luck...
ThanksHi, Emilio.

IMac Freezing, tells me to power off
Hi
My iMac PPC keeps freezing and telling me to power off or restart.
I notice the internal hard drive icon no longer appears.
I had hoped to resolve this problem by installing my startup disc onto a Firewire drive, but it has not. I can start from the drive and use the computer from anywhere of 5 to 60 minutes before it will freeze again.
Is there anything else I could self service? Do these models have internal batteries that need to be changed? I do keep the iMac plugged into a power strip that I turn off at night.
It is always hard for me to know when to walk away from an older computer.Thanks. can you direct me to where I can find the battery model number. I know it is somehwere on the Apple site, but I can't seem to find it. I'd rather have the battery in hand before I open it up.
I am also pasting below the error message. I have no idea how to interpret this.

How do I turn off messages on my iMac after upgrading to Yosemite?
How do I turn off messages on my iMac after upgrading to Yosemite?
Hi,
Open the Messages app.
Go to the Preferences item in the app's Menu.
Select the account pane in the Preferences.
Each active account should have a tick in the Enable this Account box.
This can be unticked.
This will stop accounts logging in but will not stop the app Launching in certain circumstances.
First of all check the app is Quit before shutting down the computer.
The fact the app is open even if all windows are hidden can cause the app to restart when you Start up the computer.
Messages is a Multiple window app and using the red button on the top left of a window only closes that window and does not Quit the app.
Also check the System Preferences > Users and Groups > your account > Login Items tab.
This will list items that are set to Start up when the computer does.
I have a couple of External Drive on other computers, some Anti Virus software and the common iTunes Helper plus an old version of TextExpander that will work if I launch the Preference Pane this way.

I have had my iMac for 55 days now and twice I had to power off/on and then It does not power up correctly. I verified my disk and found errors that could not be repaired (errors were associated with boot drive) I erased the drive and restored system back to the previous day. Has anyone else experienced this problem?
Since it's a new machine, contact Apple's Support and let them deal with it. Allen's already recommended an Apple repair station visit. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you might be eligible for an onsite repair since yours is a desktop machine (depends on where you're located). BTW, the AppleCare Protection Plan's the best warranty policy available for desktop machines. Get it if you don't have it before contacting Apple.
27" i7 iMac (Mid 2011) refurb, OS X Mavericks (10.9.4), ML & SL, G4 450 MP w/Leopard, 9.2.2 -
I have a 5 month old iMac running Lion and W7 with the latest version of boot camp . It has been operating flawlessly until I went to reboot into Mac tonight. Screen went black, and system is unresponsive. I've tried force quitting and turning power off. Hard drive starts, there's a small amount of drive activity and that's it.
Hi Jane, your info may still be there, look in the Users folder at root of the drive, how many users are there there?
It sounds like this may have happened...
Return to default desktop, apparent "loss" of home directory, (it can happen spontaneously too)...

After update my imac to yosemite automatically power off ifself.pls help
hi friends , I updated my imac (24-inch,Early 2009) to yosemite and update was ok.after update i restart imac then it is booting and showing apple log and coming to password page then automatically power off ifself. if i start with safe mode it is working fine. can everyone help me.
Hi.
You are running into a problem that many users of the 24-inch, early 2009 iMac 9,1's have encountered (including me). The Sudden Shutdown Syndrome is the scourge of many iMacs and Mac Book Pros.
Unfortunately, I believe that the only solution is for Apple/nVidia to revisit their geForce Tesla drivers and figure out if the power management is correct.
In your case, I'd try this:
1) Boot up your computer in safe mode and log into your user account.
2) In the Finder menu, select Go > Go to Folder...
3) Type: " ~/Library/Caches" (without quotes) into the box and press return. You will be taken to the Caches folder.
4) Select all the files in the folder and move to the trash (do not trash the folder itself). At this point, just leave them in the trash...don't erase them.
5) Go back to the Finder menu, select Go > Go to Folder...
6) Type: "/Library/Caches" (without quotes) into the box and press return.
7) Do the same thing you did in 4) This time, though, you will be asked for an administrator's password.
8) Restart your computer in normal mode and attempt login.
9) If you can log to the desktop, you may delete your trash.
Hopefully this will get you into your account. If it doesn't, you may have to do a clean install of Yosemite, go back to Mavericks, or wait for an update.
Good luck! -
