Macbook Air Shuts Down Unexpectedly During Startup following 10.5.7 Update

Downloaded 10.5.7 through the software update, installed, restarted. The grey screen appears, and after about 20 seconds the computer just turns off. Tried zapping PRAM, no avail. Any ideas on where to go from here? I don't have a ComboDrive/Superdrive for my MBA...

Some people have had more success by downloading the Combo update and reinstalling that way rather than through Software Update.

MacBook Air shuts down unexpectedly

MacBook Air (2012) keeps shutting down unexpectedly. And then shuts down during start up several times before it works again.
I was getting an "Error: shrinkdb" message in console for a while.
I tried reinstalling Yosemite which did nothing. I also tried downgrading to Mavericks which also did nothing.
I've verified/repaired permissions and the disk several times successfully with no change.
I've also got the message "unlink of file /users/***/Library/Caches/com.apple.Safari/fsCachedData" in console.
Also when repairing permissions I've gotten this message: warning: SUID file "system/library/coreservices/remotemanagement/ardagent.app/contents/macos/ardag ent" has been modified and will not be repaired

MacBook Pro shuts down abruptly during startup

Every time i turn on my laptop it starts up in safe mode and stops the progress bar. Then, it goes away and the computer shuts down. What do i do?

If you are under warranty or have Apple Care, give them a call and get a case number. Otherwise, take the computer to an Apple store or an AASP. Whichever is more convenient for you.

My MacBook Pro shut down unexpectedly and won't connect to wifi now.

My MacBook Pro shut down unexpectedly and won't connect to wifi now. All other devices in my house are connecting to the wifi just fine. The laptop just refuses to connect. Any ideas on how to fix this/what it might mean?

Try a SMC reset:

My MacBook Air shut down is slower than other macs I have seen

I think this is due to the recent Mac OS 10.8.2 update
My MacBook Air shuts down slower than usual. It will get slow and show a white screen with a spinining wheel taking up to 15 seconds.
This is longer than the startup time.
When it was new, I think it was running Mac OS 10.8.1. Shutdown was super speedy and took maybe just 3 seconds. It then asked me to update, so I obviously did, since I thought new improvments were made.
So how can I get rid of this slow shut down timings?

You might try resetting the SMC. If that does not work, take it in for service (you are under warranty).

My MacBook Air shuts down when its more than half way charged and won't turn on unless I plug it in to the adapter? Why is this happening and how can I fix it?

If you really do have a Mid 2013 Mac Air model then it is still in warranty, as the standard Apple warranty is one year from date of purchase. So take it into an Apple store and have it diagnosed and fixed under the warranty. There is some type of hardware problem that only Apple can fix.

Computer shuts down unexpectedly during operations

My computer shuts down unexpectedly during operations. The unit will run for about 20 minutes and then suddenly shut down for no apparent reason. When I try to reboot the machine it comes on and shuts down immediately. I have to wait 30 minutes to an hour before I can use it again. I am running windows 2000 as my OS and my motherboard is a K7 prom AMD. Can anyone out there help me? I am going crazy trying to figure this thing out.

Hi, I have the same problem. When windows (XP) starts loading it shuts down and restarts alone; sometimes it passes and loads complete but then after a while it shuts down. With the error free load option it is more stable but it also shuts down alone. I tried everyting that is on my hands: changed the agp to a pci VGA board, eliminated all other boards, flashed the Bios, changed the power supply, checked the Hard Drive, changed RAM, etc., etc. My conclution is that it has some relation with the VGA display but in the bios; if you use more graphics it shuts down.
My system is a 694D Pro-AR (MS-6321) mother board with Pentium III 1GHz, 768 MB Ram, Matrox G450 Dual AGP.

MacBook Pro shut down unexpectedly.

I have a MacBook Pro 2.16 GHz Intel Core duo running Snow leopard 10.6.8 that shut down unexpectedly on battery power. What can I do to fix this problem?. I hardly use the battery and I had it replaced not too long a go. Any thoughts please. What can I do to fix this serious problem?.

Carlos,
Your machine can shut down for any number of reasons, some normal. We have determine between "unexpected but normal" and "unexpected but problematical.
If your MBP's battery hits 0%, the HD will shut down automatically; simply plug in your MagSafe adapter to restore the charge. In other cases, Energy Saver may shut down your machine if it's not being used for a certain amount of time; check your Energy Saver preferences to set the times.
Some problems are more problematical. The Power Supply regulates power to your MBP, and you may notice unexpected drops in power if it's damaged.
In short, you may want to visit your local, friendly Apple Store if you notice this incidents. But before doing so, be disciplined in your research, and note when the shut downs occur, and under what conditions. If you can, also log the amount of power remaining in your battery when the problem happened. That way, the Apple staff will be able to read the statistics and figure out the problem more easily.

MacBook Air shuts down when I close it

Whenever I close my MacBook, it shuts down instead of going into sleep mode. At first, I thought it was a problem with my MacBook not waking up from sleep at all, but if I use the Sleep function from the drop down menu, it will wake up normally.
I've looked around the community to see if anyone had a similar issue, but most people say they need to reboot it to start it up again, which isn't my case at all. It just does a typical shut down. How do I make it go to sleep instead of shutting down when I close it?

Triple-click anywhere in the line below to select it:
bzgrep 'Previous Shutdown' /var/log/system.log*
Copy the selected text to the Clipboard (command-C).
Launch the Terminal 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 Terminal in the icon grid.
Paste into the Terminal window (command-V).

The power supply is clearly not reading the battery correctly, or the battery is not of the correct type for it to be able to read it. Bring it in for service to investigate these possible issues.
The CMOS (PRAM battery or Capacitor) may also be expired after 4 years time, if that's what you have.

15" Macbook Pro shuts down unexpectedly

Recently, my MBP has been shutting down unexpectedly and then the front light will flash 3 times.
I have been searching for any insight but have not found the right answer.
The MBP is running Mac OS X, version 10.6.8, 2.4 GHz Intel Core 2 Duo

May be the RAM is not seated properly.
If that is not the case, take it to the Apple Store for evaluation and repair.
Best.

Macbook (Late 2009) Shuts down unexpectedly during boot

I have a late 2009 macbook that did not have any major issues until a couple of months ago, when it shut down randomly on me, and when I tried to reboot it, it would make a *click* noise and it would turn off without any signs of problem. I've tried resetting both the pram and smc, neither of which seemed to do anything. The farthest it's gotten into boot since is just barely into the log in screen, so any hopes of getting info off of it is pretty much gone.
Any help with this is greatly appreciated.

Hi there 74235,
If I understand correctly you are unable to successfully boot your Mac because it keeps turning itself off during the boot and is accompanied by a physical clicking sound, rather than a sound coming from the speakers. I would recommend these 2 steps from the following article to see if checking the disk in one of two ways will resolve or isolate the issue:
Resolve startup issues and perform disk maintenance with Disk Utility and fsck
Try Safe Mode
If you're using Mac OS X 10.2 or later, you can start up your computer in Safe Mode, which includes an automatic disk check and repair. If you're using Mac OS X 10.1.5 or earlier, skip to the next section. A Safe Boot, which starts up your computer into Safe Mode, might allow you to start up your computer successfully. To do this, follow these steps:
Start up in Safe Mode.
After the system has fully started up, restart your computer again normally.
If your Mac successfully restarts, the issue should be resolved. If the issue continues, try using Disk Utility.
Try Disk Utility
Use these steps to use the Disk Utility app to verify or repair a disk.
If you're using OS X Lion or later, start the computer from Recovery System or Internet Recovery. If you're using an older version of OS X and your computer came with a Mac OS X Install disc, insert the installation disc and restart the computer while holding the C key instead.
When your computer finishes starting up, choose Disk Utility from the Utilities window, or from the Installer menu if you're started from an installation disc.
Click the First Aid tab.
Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
Select your Startup Disk (usually named "Macintosh HD").
Click Repair. Disk Utility checks and repairs the disk.
Tip: With Mac OS X v10.6 and earlier, always start up your computer from an Install or Restore disc when using Disk Utility to verify or repair your startup volume. Otherwise, you might see some disk error messages.
Thank you for using Apple Support Communities.
Take care,
Sterling
