MacBook Pro will not reboot after Security update or boot from disc

I recently downloaded the latest security update and instead of immediately restarting I chose to shut down the system. The next day I booted up and ran into a problem with the start up stalling on the gray screen with the Apple logo and the spinning gears.
After searching through many topics on this issues I have determined that I can likely repair permissions to resolve this issue or try a number of other options. However I can not seem to boot up from the Install disc or in Safe Mode. Booting up holding down the Option key doesn't give me any other option than the hard drive.
Does anyone else have any ideas on how I can get past this increasingly annoying spinning gear mode so that I can try to repair the damage?

This is what worked for me:
Situation: After installing OS X 10.5.6, my mid 2007 MBP began to freeze, and eventually wouldn't reboot normally, nor in safe-mode or from a disk. Also tried resetting SMC and PRAM, still would boot from disk.
Tried fysk, which worked for a while, but eventually the computer wouldn't reboot again.
Connected it to another mac via firewire in target mode and erased all the data (yes I had a time machine back-up), but still wouldn't reboot from disk.
Solution: A friend of mine tried resetting the PRAM again (command, Option P,R) but this time, he continued pressing the start button until the third chime (rather than the second as per apple instruction).
All of a sudden we were able to reboot from disk, reintall the OS X 10.4.9 and then do a regular update to 10.5.6. My MBP has been working fine ever since.
Hope this helps someone.

After updating from Lion 10.7.4 to 10.7.5, my MacBook Pro will not reboot. Why? What can I do about it?

After upating from Lion 10.7.4 to 10.7.5, my MacBook Pro will not reboot. Why? What can I do about it?

I ended up having to visit an Apple Store. They claimed that the update must have aggravated an already corrupted hard disk drive. The solution was to wipe my hard disk (fortunately I had recently backed up on Time Machine). The "Genius" also claimed this was the first time he had come across the problem. Although he was clearly able to diagnose it straightaway, and the next person he saw had exactly the same problem with his Mac, and I saw an awful lot of customers queuing up with their Macs and iMacs looking very suspiciously like they all had the same problem! So clearly Apple know what the problem is but as usual treat customers as if they're idiots in order to cover up the problem. But at least the problem is now solved (although having to take at trip out and wait in a queue at an Apple store, and then restoring from backups is a painstaking inconvenience I could well have done without). All I can suggest is that you might as well take it in. None of the "solutions" on the Forum are remotely on the ball, and all Apple "Geniuses" have clearly been told what the problem is and how to fix it. Good luck!

MacBook Pro will not boot after software update

MacBook Pro will not boot after doing an Apple Software Update (of course they will not help you). MONEY, MONEY, MONEY is the name of the game. They can cause your computer to crash and still charge you!
Does anyone have an answer to why my computer is showing a little gear spinning for hours? I have tried several things with NO luck.
Thanks-

Mac Pro will not reboot after Bootcamp attempted installation

I have an older quad-core 2009 Mac Pro. I tried to install Bootcamp before realizing that it's not supported. Now the Mac Pro will not reboot.
It starts up fine. It shuts down fine. But it just will not reboot. When I try to reboot, it just clicks like it's trying to boot to a DVD or a drive that's not there (I have since formatted the drive I was using for Bootcamp and use it for Time Machine now).
This is what I have tried:
- PRAM reset
- SMC reset
What could be keeping my Mac Pro from rebooting properly?? Please help. Thank you!!

So you tried with Mac and Windows on same drive?
And you have Recovery partition.
You made a clone with CCC as well and cloned the Recovery
Paragon makes a couple programs to make life easier.
And, Well, Boot Camp works. There are unwritten rules. There is a forum devoted to it.
2009 is not old. Old is pre-2008 due to UEFI / EFI64 and how Windows 64-bit now looks during install.
It did install but the drivers and updates and such might be an issue.
Apple does not support HFS arrays, not just that Windows won't install but to mount, their Apple HFS driver.
You left out so much and maybe your IT didn't include Windows on Mac.
www.apple.com/support/bootcamp
In general pull all your drives during install except that one Windows will be installed on.
Do get video driver from ATI etc yourself
Tell us what version, I assume Windows 8 which works fine other than a few issues - more with MacBook series and iMac or Mac Mini lines.

Macbook pro (lion) will not reboot after updating itunes

downloaded itunes update and computer will not reboot. I get grey screen with apple and swirling icon. Have tried turning on and off, and putting into safe mode but nothing has worked. HELP

Actually my MacBook pro is 2011 model! I managed to install Lion on an external disc and start my MacBook from it. Although the internal disc is seen I cannot retrieve my data. Anyone knows how I do that please?

Macbook pro will not restart after failed disk repair

This has happened twice in one week.
A routine disk verify was performed and returned errors. I reboot into the recovery drive and run disk utility. To validate the first finding, I run disk verify again. Same failure. Then I run repair disk. Disk repair fails. After this, the system will not boot. Now, even the disk utility 'sees' the main particitian, but it's grayed out. when i go to retore Lion, the main partition is not seen at all.
The kicker is that two different hard drives are involved. The first is a 500 gb Western Digital and the second is a 750 gb seagate. System is a mid-2009 MBP with 8gb ram.
I performed a full system backup this weekend but do not have it with me and will not have access to it until this weekend. Any help out there? Or am I just screwed?

Oh by the way, a mid-2009 MacBook Pro would not have 10.4.6. In fact it might not even have 10.6.4. 10.6.4 didn't get prebundled until June 15, 2010. So where you get 10.4.6 on your signature, that confused people as to what you really have.

17" MacBook Pro will not startup after software update & shutdown

Last night I powered off (shutdown) my MacBook Pro (usually I leave it sleeping). It kindly reminded me I had updates to install. I said OK install them. I didn't check to see what they were, but I believe it was just the camera raw update. I also told it to shutdown after the update.
This morning the computer was off, so far so good.
Press the power button ... nothing. no chime, no diskdrive, blank screen....
Battery level is good, power adapter good with green light.
I have command control power buttoned. reset smu. cannot reset pmu as far as I know as that happens later in the startup procedure? post chime?
I pulled the power and battery and let it sit all day, still nothing.
Any ideas on the sudden failure. The software update seems unrelated, but somewhere in the back of my head I remember hearing about some problem with a camera raw update?
It's a 1st generation 17" MBP. TIA

Just to clarify the symptoms:
Good power adapter, green light on mag-safe when plugged into machine. Good battery(s) have two, both charged.
Press power button and nothing happens, no drive spin up, no noises, no chimes, no screen backlight (even with black screen) etc.
tried control-command power button for 3+ seconds, naughta.
tried pulling power and battery, then hold power for 5 sec. recconect bat and power, naughta.
tried removing all power for 8+ hrs, naughta.
It doesn't seem to be getting power to any components on -power button down -
So, I am guessing here but seems like:
a. Power button/connectors.
B. Firmware issue as last time it was run a software update (unknown) was installed.
C. Logic board?
D. As there is a green light on the power adapter I expect it is not the Left I/O subassembly board?
Are there any other power supply boards that may be involved, or are all of those components on the main board in this machine? Is the power button part of the keyboard assembly?
TIA.

Macbook pro will not boot after snow leopard upgrade

My GF has had a macbook pro since mid 2008. It's been running like a champ since I've known her for the past 3 years with no issues. It has/had OSX 10.5.8 installed. We tried to consolidate all our pictures from all our apple devices and realized she didn't have an icloud on the old 10.5.8 OSX. So I called apple and they told me to order and install the snow leopard OSX 10.6 first and then upgrade to lion etc after that, Well we got the disk yesterday popped it in to install and it's been a disaster.... the computer shutdown for what looked like a normal restart during the installation process and never booted back up. Attempts to manually reboot leave us locked on a grey apple logo screen with spinning gear indefinately whith the Snow Leopard disk installed during boot up. With the disk removed I get the flashing file folder with a question mark. I called apple support we tried all the PRAM and SMC resets and then decided that we should go to the Genius Bar once all those failed. After an hour and a half drive to the nearest genius bar we were told that the we suddenly had a hardware issue which just happened to coincide with the new OS installation.... I'm not buying it and am looking for some help. The macbook was running like a champ until we inserted a disk recommended by apple... Any takers?

You have a five year old computer, so a failing hard drive at this point is not so strange. You have a couple of options you can try. Start with this one, but if it does not work you will have to erase the hard drive. I hope you have a backup of all your files.
Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

MacBook Pro Will Not Reboot

My MacBook Pro is having trouble restarting. I originally opened the laptop to start working and noticed the comouter was acting strange (reconnecting to Wifi after turning it off, Chrome wasn't loading). I decided to reboot the computer to see if that wouls fix the lagging/behavior. After I turned it off and back on, a message about an unprovoked caller, security agent, and something about apple software. Everytime i clicked ok to get rid of the message it kept reappearing. I stumbled across this post Has unapproved caller on screen securityagent may only be invoked by apple software and followed these directions:
"Start on single user mode: Hit the Command and S keys at start-up
Wait until the writing stops completely
-At the line, type (after root): /sbin/fsck -fy (space after the k)
Hit the ENTER key
wait until it finishes and says "... appears to be OK"
next, type: /sbin/mount -uw / (space after the t and after the w)
Hit the ENTER key
then type: rm -Rf /var/folders/* (space after the m and the f)
Hit the ENTER key
Run FSCK again (I did, just in case, but you may not have to):
/sbin/fsck -fy
Finally, type REBOOT, hit ENTER and wait until computer starts."
I tried these but it didn't solve the problem. However now whenever I try to boot, a white/grey progress bar appears. When 1/4 of the bar is loaded, some text appears on the left corner of my screen for a bit then it restarts itself and a message appears saying the computer restarted due to some error, then restarts again with the progress bar stopping and words appearing. Its a constant loop unless I manually power it down.
I read about starting it in safe mode, but holding down **** doesn't work for me. I am able to start it in single use mode, sometimes on recovery mode. I'm unsuccessful when holding down Command+Option+P+R. When I booted it in recovery mode I went to the disk utility option and clicked on something along the lines of Automatically Updating Permissions.

This is what worked for me:
Situation: After installing OS X 10.5.6, my mid 2007 MBP began to freeze, and eventually wouldn't reboot normally, nor in safe-mode or from a disk. Also tried resetting SMC and PRAM, still would boot from disk.
Tried fysk, which worked for a while, but eventually the computer wouldn't reboot again.
Connected it to another mac via firewire in target mode and erased all the data (yes I had a time machine back-up), but still wouldn't reboot from disk.
Solution: A friend of mine tried resetting the PRAM again (command, Option P,R) but this time, he continued pressing the start button until the third chime (rather than the second as per apple instruction).
All of a sudden we were able to reboot from disk, reintall the OS X 10.4.9 and then do a regular update to 10.5.6. My MBP has been working fine ever since.
Hope this helps someone.

Macbook pro will not start after login

My MacBook Pro (late 2011) with Mountain Lion OS will not start up after my login. All I get after logging in is the spinwheel forever. It will start from guest user. PRAM reset doesn't help. Any suggestions?

Adam,
Try a safe boot, power up holding the shift key note this will take longer so be patient hold the shift till you see the progress bar and try to login. If it works try logging out and logging in normally.
There are some updates availabe that you might want to install.

MacBook pro will not reboot and seems to be in sleep mode

I have a MacBook Pro and I had a USB side drive hooked to it and shut down. When I went to reboot after unplugging usb drive, the Laptop seems to be stuck in sleep mode. The boot up screen does not appear but the light where you open the screen it lit. It also makes a sound to start booting but it never boots. The computer was in great running order before this occurred.

Hi mediahero and Welcome
Try this:
Hold the power button down for 10 seconds, wait a further ten then press and release the power button in the usual way.
Good luck
Adrian

Macbook Pro will not load after TM restore

I have a Macbook Pro 4,1 and the HD was making noise so it was replaced with a Seagate 500 GB 7200 rpm and after I booted from the Install DVD and went through the Restore From Back Up in the Utilities the machine copied my last back up. However, after it told me to restart the machine, it begins to load and the gives me a gray screen with "You need to restart your computer. Hold down the power button for several seconds or press the restart button" I then reinstalled OS X and was able to see everything on the back up drive but I am needing the full system back up due to programs and the like. Any suggestions? Thanks

Hi, and welcome to the forums.
You're describing a +*kernel panic.+*
There are four main possibilities:
The new drive was not set up properly. See Kappy's post on +Extended Hard Drive Preparation:+ http://discussions.apple.com/thread.jspa?messageID=10768743&#10768743
There was something else wrong with the hardware besides the internal HD. Run the +Apple Hardware Test,+ on one of the discs that came with your Mac. It will have instructions printed on it in very tiny type.
Your backups are corrupted. While booted from your Leopard Install disc, use +Disk Utility+ to do a +*Repair Disk+* (not permissions) on your TM drive.
The problem with the hard drive corrupted something on it, which was copied to your backups. Try the restore again, from an earlier backup.
If none of those works, post back with the results and we'll try a workaround.

My macbook pro will not start after pressing the power button

I have bought a macbook pro last year and now, I have a great problem since a few months.
My macbook does not boot up, I hear no fan noices and no LED lights are blinking...
Battey is full, but nothing happens (means system will not start up).
I have also tried to start with the Power button - but the similar effect "NOTHING HAPENS".
What I don't understand is, if I do nothing for one or two days and press then the power button, the system will start up and full functionality for a few days.
And anytime I get the same problem again... and must wait also for a few days.
Can anybody support me please.
Thank you all in advance and looking forward to a fast reply.

Try reseting SMU as suggested in link below
