I have just shipped my Mac Mini to its new home and I've had reports that the panic error is appearing on boot up: "You need to restart your computer. Hold down the power button for several seconds or press the Restart Button." This screen appears on the blue window just after the grey apple screen has disappeared and does not get as far as the desktop at the same point each time. We have tried to reinstall mac OS from the original install disk but holding the "C" Key or the "Option" Key down on restart doesn't boot from disc. Is there a way you can view the Kernel Panic log before you boot into Mac OS so we can try and pin point the source of this problem. I'm wondering if this could have been the result of the shipping that has caused some hardware to come loose.
Got a tricky one here: powerbook G4, 1.25ghz, 1GB RAM (2x512), 80gb HD, APX, 15" LCD, serviceable battery, SuperDrive, OS: 10.4.11. It was brought to me with a boot problem: Computer turns on, gives the start up sound, backlight comes on, apple logo shows, spinner spins... then you get the dimmed screen, large option icon and "You must hold the power button and restart your computer": a kernel panic. I've seen this a few times before and the last time, I fixed it with a new hard drive and the removal of RAM from a bad ram slot.
What I did was: 1) Replaced existing 80GB HD with a backup 30GB drive. Then booted with a Tiger CD (the computer won't start with my disk warrior cd, nor with a tiger DVD). I was able to install Tiger and restart the computer. But the airport card doesn't show up. I tried a known good airport extreme card and this too has not shown up. 2) I hooked up the 80GB drive to my PC via MacDisk and checked it. Sure 'nuf it had loads of problems. MacDisk went through and fixed it (I'm not sure what the problems were as I'm new to MacDisk and don't know what it's looking for and fixing when it does). 3) With the computer running the 30GB known good HD, I started having the same kernel panics so I removed the first RAM chip (512MB) and tried to reset the PRAM.... here's where it went wonky. (I know, only change one thing at a time...) 4) As I said I tried to reset the PRAM (Option, Command, P, R, at start up). While I can get the computer to not boot, it won't restart. I don't know if this is just unique to this machine. Next I tried to reset the NVRAM and again got nothing. The screen wouldn't come on at all. After about three or four resets, the computer did start in Open Firmware mode. I reset the NVRAM from there and restarted (reset-nvram, reset-all). Still nothing on restart. 5) After trying to start it 15 times like this, I swapped the bottom RAM card to the top slot and removed the airport card (again, I'm stupidly trying to change two things at a time). BAM, computer boots... I put back in the 80GB drive that's been "fixed" by MacDrive and BAM, that boots fine too.
So then I put back in the airport card and it will boot, but won't recognize the airport card. I've re-seated it about a dozen times and have used terminal cleaner on the card and on the socket for the ribbon cable from the card slot to the logic board. As it sits, I can't get the airport card (either of the two) to show up at all. I did realize that the open firmware did reference a problem, but I forget the code now and when I looked it up, the references were to a failure of the airport card, but there were also more general references, so I can't be sure.
I'm thinking now that it's the airport card controller on the logic board, the bottom RAM slot and a corruption of the hard drive. Yes, there was a history of moisture into the device and I think a drop in it's past too. I'm the Mac repair technician for the people at the local bike shop, so I get to trade my repair work for their bike repair work. The problem is that they ride their laptops like their bikes, hard and greasy. I'm really wondering about ways to get the airport card back up and running. Or, baring that, a good card-based wireless adapter that I can slide in.
My Macbook pro is not booting properly. When I start it up, it goes through the normal process and gets to a point where a screen comes up telling me: "You need to restart your computer. Hold down the Power button for several seconds or press restart now" This happens every time. I tried to start in safe mode and holding down the option key and selecting the mac partition. Neither would work.
Sometime when I stop using my MBP for a minute or so, the screen goes black and won't wake up. I can see that the lights are on the keyboard and it's running but won't wake up. I will have to hold the power button down and then restart. Does any one know how to fix this? It's starting to do it more and more ofter.
I have a macbook pro, bought it May last year(2008). I don't know much about computers, but I loved the transition between pc and mac, had no trouble with it, loved to work with it, until now. I had noticed it became slower like 3 weeks ago, and a week ago, it started to freeze up on me followed by a message that said please restart your computer by pressing the power button and the screen becomes dark. When I try to restart it again, it takes a while because it shuts down again and again, until the 10th time it works. The store told me to clean intall, which I did yesterday, it seemed to have worked, it was faster for sure, but today it happened again, 3 times! Has this happened to anyone? Does somebody know what to do?
I have got the message "You need to restart your computer. Hold down..." in my MBA. Having read what have been posted before about this problem, I do not find a proper solution for it. So I have just copied the message I get from the screen after a safe boot op. It says
So I'm having issues with the computer not waking up in the morning. I guess it goes into a deep sleep of some sort and I have to hold the power button twice to turn it on, and get greeted with a computer experienced a problem message on login.
The most recent log in the system diagnostics is titled:
when occurs a suspension of hard drive activity, manually or after a period of inactivity, this suspension seems to be incomplete (a ventilator continue to run) therefore my mac (power-mac G5, OS 10.4.11) is unable to restart, no possible action from the keyboard (I must shut down and restart)

Out of the blue I keep getting a kernel panic (You must restart computer) while using my G4. All I use it for is word processing and internet browsing. Seems to happen when switching between windows.Here is my most recent crash log reports:

I've been using macs all my life but have never run into this problem. My ibook g4 just recently going crazy on me. I had it running then this dialog box came up with the power symbol in it saying i needed to restart my computer so i did as it said.
After it chimed letting me kno it restarted the gray screen came up and i had the ? folder pop up. So i looked around online and the majority said it was my hard drive. My computer also had a bad battery it wouldn't hold a charge and the ibook itself had to be plugged in at all times. My ac charger pin broke (the part that goes into the computer) so i bought a new one a 45w but just recently finding out i need a 65w! But finally my computer does not turn on at all now. Before i go and buy a new hard drive and battery and charger.
I have a DP 2.5GHz PowerPC G5 which is giving me problems. It is on all the time (server). If I try and restart it switches off but will not restar. Also, if it crashes (only happens once every few months) then it will not automatically restart. I have replaced the internal battery but this has not helped. I have also reset the PMU. Any ideas what may be going on here?

I have a late 2008 uMBP 15 inch and in safari, regardless of using the integrated graphics card or the higher end card, when I press apple t for a new tab the computer hangs for at least 10 seconds then once it finally loads the top sites page it appears all scrambles for a second, then it works normally.
My second problem is that my hinge is very loose. I can't hold the laptop at 45 degree angle without the screen falling down and closing. Will apple fix this?
I have a iBook G4 laptop and there seems to be something very wrong with it. It started a few days ago just randomly. I was reading something on the internet and the screen went black on me, but the power was still on (I clicked CAPS LOCK to see if there was power). I then proceeded to push the power button and the power went off. When I pressed the power button again to turn it on, it made that internal noise it always makes and then the fan came on, and wouldn't turn off. There was no picture on the screen at all. Completely dead. But there was power, because when I clicked on the CAPS LOCK, the light came on). I tried pressing on the power button for at least 15 seconds and even went as long as a minute, and the power didn't go off.
I went on vacation to Florida this week, I come back, start up my iMac, plug my headphones in, only to hear audio to come out of my iMac's speakers. I called apple, and I did the whole restart and hold down command, option, P and R and still nothing, I have apple care and he said I should talk to small dog. I called Small Dog gave them a description and said they would have to send it to apple because my logic board might have issues. My question is this
My 15" early 2008 MacBook Pro won't shut down unless I hold the power button. I have done extensive searches and have done the following and the problem still persists. I have pulled the battery to reset the SMC or whatever it is called. I ran disk utilities and repaired the permissions. I deleted unnecessary files in the preferences folder...... still no go..... in fact it won't load software updates because it gets hung up.... then I have to force quit it by holding the power button..... I am at a loss.
I was using garage band when the screen popped up saying that i need to restart my computer. i tried holding down the power button but the screen is frozen. the computer is making a quiet clicking sound. if i close the laptop the light stays on and the sound persists.
my brother is having a problem with his unibody MacBook that he bought just a few months ago. It won't start when the power button is pressed, the sleep indicator light turns on and that's all. There's no start up tune, and nothing appears on screen. I had a similar problem with my MacBook Pro. I was told that the logic board needed to be replaced due to too much dust or moisture. Could this be the same problem? and has anyone else here ever had the same problem?
I have macbook Pro running OS X 10.9.4 purchased in 2012 times. For past few days, I've noticed this problem- I have to long press the power button to switch on the device. Normally, the devices switches on with a simple press on the power button. But for the recent days, when I do a simple press of the power button, I think it switches on and goes off instantly. I had to long press (for around 5-8 seconds) to switch it on. After the device is on, there is no problem at all...
When I was working on my MBP last night I noticed the computer slowing down, then a sheer black wash went over the screen and a prompt saying I need to manually power off and then power on the computer with several different languages below. When I did that the computer made the on sound, opened up to the apple logo in the center and the spinning gear below. But its stuck there! I can definitely hear the laptop running but it hasnt budged for the last 12 hours.
