My Mac keeps telling me to shut down my computer

My MacBook Pro is showing me a "You must shut down" message, and after I restart, it appears again before I can even login. Is this something I can fix or do I need to bring it in?

It's a kernel panic - most often this is due to faulty memory, but logic board problems or a failing hard disk can cause it as well as improperly configured external hardware.
Run Apple Hardware Test. If it reports "no trouble found" then run the extended tests. Report any problems it finds.
You don't know which version of OS X, or which MacBook Pro? Knowing both of these details will help get you started in the right direction.

My ibook keeps telling me to shut down

i have an ibook g4 which ive had for about 4 years, and starting just recently a gray screen will pop up telling me to shut down. The screen is gray with a large power button watermark in the background, It says "you need to restart your computer. Hold down the power button for several seconds or press the restart button". it is then repeated in 3 different languages. Once I have restarted my computer a window pops up saying " the computer was restarted after mac OS X quite unexpectedly, click report to see more details or send a report to apple. If i click on report nothing happens, it only lets me click ok. This happens very frequently and usually when im online, but not all the time.
Is there anything I can do to fix this problem from happening?

Try shutting off Airport and connecting to your router via Ethernet for a while. Does this help?
What you're seeing is a Kernel Panic; these are often caused by hardware issues. With the iBooks, RAM and the Airport card are two of the most common culprits.

Macbook air 11in 10.7.4 keeps asking me to shut down my computer?

This just started this evening. I get a pop-iup every 30 secs or so asking me if i want to shut down my computer. There's also a box that asks if I want to reopen the windows when I log back in. There are four choices - restart sleep cancel shut down. It seems to toggle between 30 and 60 seconds and then sometimes one right after the other in quick succession. Very strange, first time seeing something like this. I was carrying my air when I managed to touch several buttons at once and wonder if I messed something up. Does anyone have a solution? Thanks! T

I don't think he is descibing a kernel panic. He is describing the dialogue box that comes up when you press on the power button in the middle of a session. I have two machines that are now constantly asking if I'm sure if I want to shutdown. I keep hitting the cancel button but, it comes right back up.
Tried resettting the pram but, that didn't work. One machine is a Macbook Air and the other is a MacBookPro. Both have 30" Cinema Displays with the dual-link to mini-displayport adapter. Both Macbooks have thunderbolt ports are running Lion. This was not a problem under Snow Leopard. If I disconnect the monitors, the dialogue box stops coming up.
Is there a incompatibility between thunderbolt, Lion and the older 30" Cinema Display?

My mac book keeps telling me to shut down and restart

Mt Macbook is about 6 years old. It is now not strating up: I keep getting a message to shut down and start again. I have tried to perform a soft reset; now the computer just shuts off a few seconds after starting. I do not have the installation discs. Any suggestions?
I do not mund losing the saved files; I performed a back up just a few days ago. I just want the computer to start again.
Thanks

Sounds like you got incompatible or bad RAM.
Return it and buy from OWC or Crucial

CS6 64 bit (for windows) installation keeps telling me to shut down Bridge CS5 which isn't running.

I've checked the Windows 7 Task Manager and Bridge CS5 does not appear. Can someone help with what I'm to do so I can finish the install?

This error occurs when Adobe Bridge is configured to start at login, so it is running in the background.
Please refer the kb article for resolution:

Mac Pro keeps freezing & no longer Shuts Down properly

Hya.
Im using a Mac Pro in work (Mac Os 10.5.8. with 2.66 GHz Quad-Core Intel Xeon) . One day while doing a "Save as" in a program, the program froze/became unresponsive. In the Force Quit tab, it says "not responding", so i click force quit on it. It closes the window ive been working on and i get the message that the program has closed, BUT in the Force Quit tab, it still shows it listed and "not responding" next to it. It is also showing as running in the dock still. So obviously i cant restart this program, because its unresponsive. I have to shut down the computer, it shuts down everything else, but gets stuck trying to close down this frozen application, so it doesnt shut down the computer and i have to just switch the computer off.
I thought maybe it was just one program, but its litterally any program, could be safari if i say...click a box in facebook, or sendspace where it asks to search my computer for a file, if i ask it to do this, then the program freezes. It seems to mostly happen when i ask the computer to search for something i guess. "Save As" in most programs. Or if i click to import an image into a program, then bam, freeze.
Sometimes even "Finder" freezes and i have to just switch the computer off.
I generally get about 20-25mins without it happening, that is if im not heavily "saving as" or importing things, or asking the computer to do anything "tough".
Also, if one program freezes, and i ignore it and keep using another program, within a few minutes the next program im using freezes.
Some of the things ive tried are killing the running program in the Terminal application, and trying to quit the process in the Activity Monitor application. Neither work in closing the frozen program.
Ive used Disk Utility to see if there are any problems with the disk and there are none. We also bought DiskTools Pro and it also sees no problem with the hardware.
Originally i had something like 40gb on my desktop, i thought this might be slowing things down, but ive cleared it to nothing on the desktop and the problem continues.
I know I could reinstall the operating system, but i just dont like the idea of having to put everything back in its proper place again, and files "linking" up to their original place.
Not sure if this ties in with the problem, but we have an external hardrive plugged in which used to automatically sync up with time machine. This no longer works, and havnt been able to Back Up since the problem started.
Anyone have any idea what could be the problem before we have to send it off to get repaired?
Thanks in advance!

that is why my approach
clone your system
be ready to restore if needed
don't rely on Disk Utility
have an emergency boot drive / a working clone
keep data on another drive
spare extra drives
probably Disk Warrior has been rated #1 for over 10 yrs to rebuild directory
you should never need to reinstall, but you do need backups and how to use them

I have an MAC OSX 10.6.7 and when I turn it on the fan keeps running. I shut down/turn on and it's the same. Any suggestions? Thanks.

jean156,
I am a little confused, you are posting in an iMac forum however your profile only indicates you have a MacPro. While I agree a SMC reset may help please carefully read the link The hatter provided because different Mac's have a different processes for resetting the SMC.
In the mean time you may want to update your profile (Your Stuff in upper right and click Profile) and also please post in the correct forum to avoid confusion.

I did an upgrade from 4.0 to the new 6.0 about 5 months ago. After the upgrade installed it said reboot system to apply upgrade. Now it wont open and keeps telling me that the older version needs to shut down the computer and upgrade the old version.

Look at original question. When I did the download to the new 6.0 it said everything was fine. Then when I tried to use the firefox again it said an older version needed to shut down my computer so that it could upgrade the old version. It wont let me do anything and all it says is shut down computer so old version can upgrade. It wont let me open the program or remove it or anything. PLease help me with this. I really like Firefox but this has been going on for 5 months now and I still dont get answers from you. How do I fix this???

How do I get my mac mountain lion to stop saying, "You shut down your computer because of a problem?

My Mac Mountain Lion desktop computer keeps saying, "You shut down your computer because of a problem." How do I keep this from happening?

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the page that opens.
Select the most recent panic log under System Diagnostic Reports. Post the contents — the text, please, not a screenshot. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header and body of the report, if it’s present (it may not be.) Please don't post shutdownStall, spin, or hang reports.

I'm getting an error message telling me to shut down my G5 OS X 10.5.8. this happens as much as twice a day. do i have a virus or malware?

Is the screen in multiple languages saying to restart? If so, it's a kernel panic. It's highly unlikely you have a virus or malware.
Kernel panics are usually caused by a hardware problem – frequently RAM, a USB device or a Firewire device. What external devices do you have connected? When trying to troubleshoot problems, disconnect all external devices except your monitor, keyboard and mouse. Do you experience the same problems?
To eliminate RAM being the problem, Look at this link: Testing RAM @ http://guides.macrumors.com/Testing_RAM Then download & use Memtest & Ramber.
Do you have an Apple Hardware Test disc (the AHT is on the Install/Restore DVD that came with your Mac)? Running the Apple Hardware Test in Loop Mode is an excellent troubleshooting step for finding intermittent hardware problems. It is especially useful when troubleshooting intermittent kernel panics. If Loop Mode is supported by the version of the Apple Hardware Test you are using, you run the Extended Test in Loop Mode by pressing Control-L before starting the test. Looping On should appear in the right window. Then click the Extended Test button.The test will run continuously until a problem is found. If a problem is found, the test will cease to loop, indicating the problem it found. If the test fails, be sure to write down the exact message associated with the failure.In some cases, RAM problems did not show up until nearly 40 loops, so give it a good run.
May be a solution on one of these links.

Attempting to download Maverick it has been running for nearly 24hrs. I have tried shutting down the computer but the setup assistant keeps canceling the shut down.

Just hold down the power button for about ten seconds and the machine will turn off.
I'm not sure how fast your Internet speed is but my Mavericks downloads usually only take about 20-25 minutes for a 5.33GB file.
No telling what will be waiting for your when you power back on... call back if you can't login to your computer.

I performed a software update and the system is installing an update but it has been running for over 24hrs and keeps saying "This may take a few minutes, don't shut down your computer" Can anyone help?

Hello cor-el, thanks for your reply. I changed my settings for downloads to desktop and it has appeared on there. When I double click I am asked which program I want to open file. I click firefox and another box "opening install" says I have chosen to open the file which is an application and do I want to save it. This is the only real option so I press save file. I get a box saying this is an executable file which may contain viruses - do you want to run. I press ok and the final box showing C drive file name and desktop appears stating application not found.
This happens the same whenever I try to install.
To my untrained eye the application is not being recognised as an application and I cannot work out how to get it to do that.
My plugin is still showing as out of date.
Is there anything you could suggest. Thanks for your time.

Mac book pro trys to shut down while downloading?

my mac book pro trys to shut down while im downloading for some reason..

Hi Monroeeugene,
I'm not sure if you mean shutting down or going to sleep ... but this article will explain how to change your sleep settings so your downloads don't get interrupted.
Mac Basics: Set your preferences
http://support.apple.com/kb/ht2490
Change your Mac's sleep settings
To conserve energy, all Macs have the ability to sleep. When you haven't used your Mac for a set amount of time, it enters a low-power mode until you wake it by pressing the keyboard, trackpad, or moving the mouse. Sleep doesn't turn off your computer; it merely puts it into an inactive state that consumes less power.
Open System Preferences
Choose View > Energy Saver.
Choose the Power Adapter or Battery tab. If you're using a desktop Mac (a Mac mini, iMac, or Mac Pro), the Power Adapter and Battery tabs do not appear.
Move the sliders for both the computer and display to change the times in which they go to sleep.
Select any other options you want, such as sleep and wake.
Hope this helps ...

Mac book pro, overheats and shuts down as 2 hours the use

mac book pro, overheats and shuts down as 2 hours the use

Hi, I am facing the same issue.
Did you able to solve your issue? Please advise.

Mac book pro mid 2009 shuts down after a few hour then will only boot after waiting and pressing power button numerous times. I am running mountain lion with most recent updates.

Mac book pro mid 2009 shuts down after a few hour of use and then is very difficult to reboot. Sometimes I have to wait hours, sometimes I have to repeatedly press the power button and then it will slowly start a little longer each press untill it completely boots. It has done this three times know. Each time I was watching a video.

Try running the Apple Hardware Test - sounds as if you've hardware issues.
