MacPRO boots and shuts down in 1 motion
Evevning forum,
After returning home I have tried to bootup my MacPRO (early 2008) and the machine is acting weird. Before I left all was working fine. It seems as soon as I press the start button the computer tries to power up and shuts down straight away, within in seconds. Could this be a power supply issue as many seem to have fallen fate to this issue. If so wha are the cost of a new one?
Thanx in advance
Was it plugged into a UPS?
Was it unplugged from power?
Have you tried an SMC Reset?

Symptoms
If your Macintosh computer won't turn on, here's how to troubleshoot it. Please keep in mind that although your computer may display similar symptoms that prevent it from showing video, this article discusses what to do if the computer won't turn on, meaning that when you press the power button:
You don't hear a startup chime.
You don't hear any fan or drive noise.
The power button or power indicator doesn't light up at all.
If your computer doesn't display any video, it may display one or more of these similar symptoms when you press the power button:
You may hear a startup chime.
You may hear fan or drive noise.
You may see the power button or power indicator light up.
If any of these conditions occurs, see Troubleshooting: My computer has no video instead.
Resolution
If your computer won't turn on, try each of these steps:
Make sure that the power cord is plugged into a working wall outlet, and that it's properly connected to the power adapter. (To check if the wall socket is working, plug in a lamp or other electrical device.)
Make sure that the power adapter is properly connected to the power port on the side or back of the computer.
Disconnect all accessories that are plugged into the computer, such as a printer, hub, or other mobile device.

Extremely slow boot and shut down
I've been experiencing VERY slow boot up and shut down times (in excess of one minute for both booting and shutting down). I've removed everything from my login items and I still have the same problem. I have a late 2007 black MacBook with 10.5.3 on it. Any help would be appreciated!
Try running a cache cleaner and clear out all system and user cache files. Onyx is a good freeware application for this. There are several others of course.

Slow booting and shut down. How?
I just bought my macbook pro 13" just a month ago, and now the motherboard has crashed. Sent for repair and is useable now, but the booting up and shutting down took longer than before. What should I do?
Hey Joseph! Thanks for your help. Now the shutting down seems to be faster by a bit. But it still shows the blue screen which i hate to see. Starting was as usual slow.
The only program that needs running upon start up was MSN. And it usually doesn't gets signed in by itself even when it's checked at "auto sign in". And I'm not sure if msn itself is having any issue, or has it got something to do with my mac, because sending messages online was kinda terrible. There were many times where I typed a chunk of messages and after 5-10 mins then they told me that it wasn't sent at all. Plus it keeps logging me out. SO ANNOYED.
And lastly, safari web browser KEEPS CRASHING. that i have to force quit it many many times. I wrote to Apple support alr. Hope that they will get back to me soon abt this. It's kinda frustrating to use it when there are so many issues whereby I don't even know the cause of.

Extremely slow boot and shut down process; very stance crashes;
I have re-installed OSX lion three times already. Everytime I carried out a clean install on my Macbook core duo 2 3Gb ram, 500GB hard drive, 2006 model.
All the times the OS appears to be as slow as ever on booting (approx 2 minutes or more).
The apple logo stays on for quite a while then It disappears and the cursor appears on screen then the logo comes back on again for another couple of seconds and then the desktop slowly appears but still i have to wait for another couple fo seconds before I can use it.
Then once the desktop is up and running if I open safari along with Mail both of them stay unresponsive for a while before I can get to do some work.
Not to mention the shut down process; it takes at times up to 2 minutes.
I checked all the processes in the Activity Monitor and there doesn't seem to be any process slowing or taking loads of memory.
The only app that i could think of is Quicksilver which I have promptly removed/unisntalled without any changes in boot times etc.
Is there any other thing/test I could carry out to find out or resolve this issue??
I have also run disk utility Permission check/fix, disk check from Rescue disk but nothing seems to work and I can't find anything to help on the net.Try running a cache cleaner and clear out all system and user cache files. Onyx is a good freeware application for this. There are several others of course.

MacBook Pro won't boot and shut down on its own.
Hi, I am running a Macbook Pro. My problem is that the OS froze during use, and I could not move the cursor. As which point I force shut down by holding the powerswitch. From that point onwards I could not get the machine to boot, it keep getting stuck at the grey screen with Apple icon. After loading at the grey screen for 15-20 mins it shuts down on its own.
I've tried to reset SMC (shift-control-option + power button) and PRAM (Command-Option-P-R) but it dint work. Please help. Thanks.It appears your problem occured after you upgraded to 10.8.2, but if you did it right after the SSD and RAM switch then it's hard to tell exactly what is causing the issue.
I advise returning back to factory, hold command option r boot and wipe everything and reinstall 10.8
..Step by Step to fix your Mac
If the problem continues, then make a warranty/AppleCare call, hopefully you didn't strip the screw heads or leave any other tell tale damage inside.
If your fine on 10.8.2 for some time, then switch the RAM and do a hardware test extended or Rember or Memtest to make sure the new RAM is not the issue.
If that's fine then Carbon Copy Cloner to the external SSD and hold option key down to boot from it and test that.
Then do the internal SSD switch and test that.
Take your time, Mac's are so finicky and you can't just slap this or that and expect it all to immediatly work like it should. -

USB drive with install image is showing in Startup Manager on a Mac Pro, but wont boot. Showing circle with cross strip, and shut down automatically. USB device are made and work on two different MacBook Pro, but used on Mac Pro. Any help?
OS X installers have always been fairly specific, hardware-wise. I haven't read anything reflecting that situation with the Recovery HD, so it may be that the Recovery HD created for the MacBook Pro does not have the necessary drivers for the Mac Pro. Obviously, nothing definitive here, but a possibility.

Mac Mini LED blinks and shuts down at startup, takes 2-3 tries to boot...
I have a Mac Mini PPC 1.42GHz. When i boot it up after non-use (cold), the LED blinks once per second and it boots all the way into MacOS and shuts down several seconds later. It will usually do the same thing the second time around. On third boot its usually fine. Not thinking its related, I have reinstalled MacOS anyways. No good...
Thanks,
RichWelcome to Apple Discussions!
The flashing LED is usually indicative of a power-on self test failure, normally leading to the system failing to boot at all. Once per second would indicate the system fails to recognize available RAM.
The fact this happens when the system is cold (with an implication that it doesn't happen when the system is warm) might indicate the RAM module is no longer firmly inserted, or that the contact face on the pins has oxidized slightly. In this situation, I'd begin by opening the system and removing and then reseating the RAM - in the G4 minis this is relatively easy since there is only one RAM slot, and it is exposed with just the top of the casing removed. -
I did force shutdown on my MacBook Pro (2006 year, 15.4"), so, when I tried to boot, it shows apple logo (as usual) and shuts down. When I booting MacBook with Option key pressed it shows lock icon and field for password. Please help me.
Wait for advice on repairing a damaged filesystem. Forceshutdown stops processs in mid-stream and leaves some parts not-valid.
Do not proceed until you get that avice. -
Is Lion slow booting up and shutting down?
After I installed Lion, my macbook pro is slow to boot up and shut down. How can you turn off "re-open windows when logging back on"?
The beeps on startup are often indicative of RAM problems. The opening chime is the only normal noise on startup. Shutdown should be essentially silent. To the Apple store, PRONTO!

New 27" iMac taking ages to boot up and shut down
i JST bought, literally a week ago, a new 27" imac core 2 duo and it takes forever to boot up and shut down
boot up: 30 - 40mins
shutdown: undetermined (shut down at 1am, was still shutting down at 7am when i got up for work!)
anyone any ideas?For the startup part, I would reset PRAM
http://support.apple.com/kb/HT1379
and once it gets to the Desktop, open System Preferences +Startup Disk+ pane. Make sure your internal drive is selected (highlighted) as the startup disk choice.
Not sure about the shutdown issue, since there are many potential causes. One could be a running process that is having a problem quitting. Try starting up and then immediately shutting down (give it a few minutes to fully start up but shut down before you run anything else). Does it shut down quickly, or do you have the same problem? -
My macbook pro is stuck on grey screen with apple symbol in center with the progress circle under it continusly spinning. After I had turned it on. Prior to turning it on I had to force close and shut down a few hours prior. Please Help I have tried everything I know to do
Unfortunately this means that there is a problem in the boot sector of your hard drive. It might be indicative of a fundamental corruption in the coding that allows your computer to boot your operating system from your hard drive. I had this problem twice and it resulted in me having to get a new hard drive and restore my data.
In other words, your computer can't talk to your operating system so you can't access your data.
Here is my advice: DON'T CALL APPLE TECH SUPPORT though they are kind and usually helpful it will take you an hour just to explain the situation and they will only tell you to do what I'm gonna say here.
First: Shut down your computer completely
Two: boot up while holding down the following keys: command, option, p, and r. The computer will reboot 3 times. This solution will likely fail so if you're frustrated skip to the next step.
Three: Boot up while holding down the option key. Select recovery drive. Select your default language. Select disk utility, click on Macintosh HD, and select "verify and repair volume." Likely the verification will produce some line like "unused node not erased." Or something like that. If anything using the words "node structure" comes up, you need a new hard drive.
If after verification and repairs you still can't boot I sincerely hope you have apple care because you will need a new hard drive. Set up an appointment to come in to the apple store, they will tell you to go and get data recovery, just ask them to give you the old hard drive. Unless you have an up to date backup in which case you can just restore from that. If you're lucky the only issue is with the boot sector which means that if you ask them to give you the old hard drive, you can buy an enclosure and you have effectively been given a free external hard drive. It still works to store data just not to load an operating system.
If you have a back up drive bring it to the apple store and they'll do the whole thing right there, it should take around an hour and a half but may take longer.
Hope this helps, it's annoying but it's your safest bet.
All the best. -
Why is my 2010 macbook pro freezing and shutting down every time I start it?
Today, after using my macbook pro to upload pictures from my iphone, my computer started having problems and shutting down. The screen goes gray and a box pops up saying that a problem exists and that I need to restart my computer. I've only had the macbook since last November, so I don't understand why I've been having so many problems with it. This happened a few times to a lesser extent in Senegal when I was there for 5 months. I used a mac power adapter so I don't think it could be an over-charge problem.
Please help!Sounds like your iphone is causing kernal panics.
Unplug everything. Keyboards, mice, external hard drives, the lot.
One of these devices could be causing it.
Then, grab your Install DVD, and boot while holding the C button.
Select your language.
Go to Utilities > Disk Utility > Repair Disk + Repair Permissions
Then restart, and every once in a while, add one of the keyboards/mice/iphones/hdd's one by one to see if they are causing issues & therefore identifying the culprit. -
Recent freezing and shutting down every down 10-15 minutes and hard to log in to internet very slow
My son has 2009 Macbook white version and recently (last week or so) freezing all the time, cannot log on to internet, and shuts down every 10-15 minutes. Is there a download (free hopefully to clean it up for any spyware or maleware). He is a student and very busy in University and cannot be without the computer?
He will need something to back up onto like an external hard drive. The disks are necessary if the hard drive needs to be repaired, you can't repair the boot volume so you need to start up from an install disc and run Disk Utility from there. When you talk to him have him resettle SMC and pram, sometimes unexpected shutdowns can be corrected that way. The freezing is another issue, I'm concerned with the health of his hard drive. Another thing to ask when you talk to him is how much total space and how much free space does his hard drive have?
