Pop Up Screen-"must power off computer"

I have been experiencing freezing and random shut downs of my Macbook. I recently had a gray screen pop up that said I needed to power off my computer, where it did not allow me to do anything else but shut down. Now, I am having difficulty turning it back on. Do I have a virus? How can I fix this problem?

There are no known viruses for Mac - was the warning screen in several languages? If so, you were most likely experiencing a kernel panic.
If you will go to your Help menu in Finder menu bar and type in kernel panic, there will be information and instructions on how to proceed. If the computer will not start, try starting it in Safe Mode (excerpt from Apple Help):
Shut down and wait 10 seconds.
Press the power button.
Immediately after you hear the startup tone, hold down the Shift key (you should press the Shift key as soon as possible after you hear the startup tone, but not before).
Release the Shift key when you see the gray Apple logo and progress indicator.
To leave Safe mode, restart the computer normally.
If the computer successfully starts in safe mode, choose Apple menu - Software update and then download and install any updates available.
Uninstall any plug-ins or other enhancement software from third parties.
Continue troubleshooting as per Apple Help. You might also want to read the following articles:
http://support.apple.com/kb/HT2546
http://support.apple.com/kb/HT1392
http://support.apple.com/kb/TS1892
Hopefully this will help you troubleshoot the issue causing the kernel panic.

The screen shows problems with iCloud only choices are ignore or settings, however nothing I do will unlock it from this screen, cannot power off keeps that bubble on the screen. What do I do?

Try this now.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

After migrating to new Mac iCal pop-up screen is mostly off screen ...

After migrating to new Mac iCal pop-up screen is mostly off screen and I can't seem to find a way to get it so that it pops up in the middle of the screen or anywhere else where I can see the whole thing.

This is a known bug which began to occur with the 10.4.8 update. I suggest you file a bug report with Apple. Its quite annoying and hopefully, the more people who contact Apple about it, the more importance they will give to fixing the problem.

Attempt to power off COMPUTER failed

When I try to shutdown my T60 Thinkpad (2623-D3U) using the Start | Turn Off Computer | Turn Off sequence, it does NOT shutdown until I run through the sequence a second time.
I'm running Win XP Pro sp3 and all the critical and recommended updates are installed.
When I check the Event Viewer System Log, I do find a Source:USER32 Event ID: 1073 Warning indicating:
'The attempt to power off <COMPUTER> failed.', but related explanation.
I don't want to jump all over Microsoft (just yet), but I don't remember having this problem prior to sp3.
I've seen threads for the T61s with similar issues, but no solutions. Much older threads seem to point to Roxio.
Any suggestions about where to start checking?

"must power off" msg

Hi all:
Got a 3-yr old or there abouts G4 powermac mdd. Been a GREAT system, w/ no probs at all.
This morning, however, TWICE.....I got the msg on the monitor (in several languages) "you must power off your system".....or something to that affect.
Both times I complied immediately, & after the 1st time I did repair permissions. Haven't turned back on since the 2nd time.
What causes this? Is this a hardware or software issue? overheating??
would love to get some expert advice on this.
Thanks!!

Hi-
The logs are generated automatically. As long as log clearing maintenance has not been performed since the panic, you should have a record.
Open Console, and look through the system logs for the panic log. Select Logs, and then click the triangle to expand /library/logs, and /var/logs.
Should be something in there somewhere.

I am having difficulties with iPhoto slideshow. The slide show stops in the middle of a presentation and the system crashes. I must power off to exit the app and restart my MacBook pro.

Wow. Okay...
I'll let the real veterans in this forum tackle your issues one after the other. But, I can tell you, all will be well.
My only comment would be re: your computer specs:

To be completely honest, FCPX is a RAM hog. It just is. But, RAM is relatively cheap, and the pay-off is good.
4GB is right on the edge, IMHO. 16G is ideal.
I wish you luck, hang in there, and standby for more help.

Cannot access safari but a small window appears on screen, cannot power off or restart

While on safari, it closed but has left a small window of page i was surfing, I cannot power-off ipad and will not let me go on safari or access anything

Close Safari and reboot your iPad. If you cannot close Safari or navigate to the home screen, just try the reboot described below.
Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to Safari if you don't see it, and then swipe "up" on the app thumbnail to close it.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Must Power Off Message

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.

Mac mini will not complete shutdown-closes desktop, goes to blue screen, and spinning icon just spins forever, so must power off to reboot.

Recently, My Mac-mini will not complete the "shutdown" or "restart" routine; it closes the desktop screen, goes to the light blue screen, but then the spinning indicator (not the "wheel of death") just keeps spinning forever with no shutdown (I've let it spin for >2 hrs.). Have run disk/permissions verifications and repairs from applejack, disk utility, Mactuneup.app & all report ok. Any suggestions, please?

Lid won't latch - powerbook won't wake from sleep, must power off and on -

the catch on the lid of this 12" Powerbook G4 does not come out when the lid is closed; it can be brought out with a small tool. what is going on? the computer does not wake from sleep eitherl, must be turned off with power button and then turned on. If only the display is set to sleep, then it wakes up as expected. Are the two related? Is this a case for resetting the Power Management Unit, I could not be sure from the Apple article.

Bob:
Try starting up in Safe Mode, logging into your account, emptying Trash, then rebooting normally. I have found this helpful when I have had sleep problems with my Pismo.
Is this a case for resetting the Power Management Unit,
Wouldn't hurt to try.
In terms of your latch, it is likely a mechanical problem. When the tongue is pulled out try putting a very small amount of lubricant on the tongue and working it back and forth.
Good luck.

IMac gray screen when turning off computer

I added an external harddrive for timeline, since doing so I have had problems when I try to turn off the computer. It has a gray screen with a little circle that cycles. What can I do to stop that?

Hello,
Ideally you need to boot from the disk as you have no other media advisable. (e.g your hard drive)
Without some form of system disk or restore you wont be able to diagnose the problem with your hard drive.
By using a Mac OS X system disk you can load up the Disk Utilities and repair the hard drive if shown it's available. If it's not available you would need to replace the hard drive and reinstall Mac OS. Without any disk to support you, you are going to struggle.
You can obtain replacement disk, both retail copies or system disk on the Internet.
If you know what version of Mac OS X you had install (I'm guessing that it would have been 10.3, but would recommend 10.4) A retail disk is normally black with a colored 'X' on it, while system disk are always.
Always try and obtain a copy of the system restore disks (Gray) for your iBook
Ebay is another outlet that has genuine system disk for sell, but like any auction site, it's as and when someone is selling them.
The only other thing you could do is take it to a Apple repair agent who could check the hard drive on your behalf. That way you can get confirmation if the problem is the drive or some other fault. They may even help restore the OS for you.
I can't think of anything else to try without some form of disk to help you.
There maybe just one other small thing you could try.
When booting up, firmly rest your palm of your hand on the iBook next to the tracker pad on the left side.
If it works then it's another fault that I'm aware of.

No Screen-dim Power-off Warning

Running the latest software, both iTunes and iPhone, and my iPhone is powering-off after 1 minutes without the "dim screen" warning that I used to get. In other words, at 45 seconds, the screen is not going dim; the iPhone just powers-off after 60 seconds.

it maybe that the sunblade is set to run max diags on the obp which means the screen will reamin blank until it starts to bootup.
