Macbook pro won't boot after installing update 10.9.3

macbook pro won't boot after installing update 10.9.3

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

MacBook won't boot after installing update 10.9.2

Hi there,
After successfully installing the 10.9.2 update on my MacBook Pro, I was able to boot to the updated system once. Then, suddently my macBook crashed and I was unable to boot again.
I managed to find a way to backup my files using the recovery mode and the Disk utility, however this wasn't straightforward to me since I was using FileVault..
Does anybody else have a similar experience with the 10.9.2 update?

The login screen appears as usual, and I am able to put username/password. Then, it fails to login and it returns the user to the login screen without mouse or keyboard working.
I booted using Command Button + S (single-user mode) and I see the error
"error loading mach kernel 0xe"
At least, I am able to boot in recovery mode to backup my disk :-)

System won't boot after install unless partition seperation is done.

I'm trying to do my favourite partition scheme of 'root partition only'.
I've followed this guide.
I've followed all of it except for the partitioning scheme it showed me and the formatting and the mounting.
Here is what I did instead (after cfdisk for 1 bootable root partition):
mkfs.ext4 /dev/sda1 && mount /dev/sda1 /mnt && mkdir /mnt/home
... and so on ...
The installation worked fine, but, when I rebooted. GRUB shows up, I chose the first option, something similar to "No kernel found." appeared.
Weird...
Currently, I am forced to stick with the root and /home/ partition split.
Does anyone have a solution to this?

Yes. Properly configure your boot loader. If you have a single partition the settings need to be adjusted so that the bootloader can find the kernel and initrd which are no longer in the base directory of the boot partition - they are in /boot/

My Mac Pro won't boot after installing the latest update

Im running the latest OSX on my mac and recenty did a small updated that i believe contain a few security thing and bug fixs but when restarting the machine after the update it would not boot again after the apple logo has appeard apple script is displayed on the screen contain what i think is boot script failing to run. I have been able to boot the system in safe mode. does anyone have and solution for this as i realy don't want to reinstall the OS
Thanks

The most common cause for "Won't boot after software Update" is Directory Damage that existed before the Update, but was made worse by adding files during the Update.
The most common cure for that Directory Damage problem is to boot in Safe Mode, which takes five minutes to repair the disk, then comes up demanding your username and password, even if you normally auto-login.
Rarely, third-party add-ons are made obsolete by an update. In this case, booting in Safe Mode (with few Apple extensions and NO third-party extensions loaded) works fine, even if normal mode does not work.
Have you tried normal mode again after your Safe Boot?

System won't boot after update

After installing the latest system update (from Leopard 10.5.1 to 10.5.2) on my Dual Processor PowerMac G5, I was able to restart then within 2 minutes a freeze. I couldn't force quit...had to power done.
Upon powering on, my screen hangs on the gray screen for about a minute (with the clockwise powering up status symbol), then it shuts down on its own. It won't boot into safe mode. In single user mode, it tells me there is a "disk0s2: I/O error" ... Is my hard drive dead? I've tried resetting the PRAM, resetting the PMU button, unplugging all 3rd party devices, but to no avail.
I'm hopeful I can recover files somehow. Where should I proceed? I'm not sure exactly how the internal drives work. Can I, for instance, unplug and remove the top internal drive and place the 2nd internal drive where the top one was and see if i can boot from that drive?? Thereby determining which drive has the issue? Any advice is appreciated.
Thanks so much!
Sean

Can you boot off the leopard DVD and run the disk utility disk verification on the drive? If it's a hardware problem then there's probably not much you can do. If you have a TM backup of your system then you should be ok, since you can replace the drive and then restore your system to it from the TM backup.

Macbook won't boot after installing Security Update 2008-007 (Intel)

I installed security update 2008-007 (intel) on my MacBook last night using Software Update, but now my machine won't boot at all. All I get is the gray start-up screen with the dark gray apple, but there's no spinning progress bar or anything. After 5 minutes or so, the machine auto-restarts, but again hangs on the gray start-up screen. It does this over and over again until I shut it off. I tried to boot into safe mode by holding down shift right after the chime, but it still wouldn't boot (again, not even a spinning progress bar). Can anyone please help me? I really don't want to lose my photos/movies, etc. I'll backup everything promptly if I can just get it to boot. Thanks.

Hi jared-lee, and again, a warm welcome to the forums!
First for safety, "Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."

Jaguar won't boot after iPod updater install

Greetings,
My Jaguar (10.2.8) will not boot after I installed (via Software Updater) the iPod Updater 2005-11-17 on my iMac.
I've run Repair Permissions and Repair Disk using Disk Utilities (from both a Jaguar and Panther install CD) and zapped PRAM (3x). No problems show up on Repair Disk. I get the start up chime and a gray screen with the gray Apple logo, but no spinning circle. That's as far as it goes. I cannot boot to Safe or Single-user mode (not sure what I can run except fsck -y).
I can, however, boot to OS 9.1.x on the hard disk; I'm hoping to copy/recover files over the newtwork.
Any ideas (short of erase/partitioning drive and reinstall OS)?
(Don't know if this has anything to do with my post- iPod Update 2005-11-17 problems, but. . . My original iMac drive was 4Gb. I Carbon Copy Cloned the whole disk to a formatted 30Gb hard drive mounted in an external USB drive enclosure, removed the larger drive from the enclosure and installed it in the iMac. Worked like a charm. I've used it this way for almost a year, enduring several application updates, e.g. security updates, QuickTime, iTunes, even one iPod updater. I have noticed, however, that I cannot reinstall Jaguar or install Panther to this HD because the system is not in the first 8Gb of the hard drive. Apparently, I need to create a partition on this 30Gb drive that is < 8Gb in size before I can proceed with the install/reinstall. I thought this limitation was corrected with Panther, but not so?)
Thanks,
Richard

Figured it out.
I couldn't boot to OS X because, it seems, the iPod updated caused Jaguar to behave in it's predictable pattern of not booting properly from a partition > 8Gb in size on this iMac (a 233Mh model that Apple says is affected in this way, http://docs.info.apple.com/article.html?artnum=106235). In my case, I had Carbon Copy Cloned my 10.2.8 to a 18Gb drive. No problems occurred with running it. However, this was the first set of updaters I've installed on that OS since that cloning operation. And it simply wouldn't boot.
I booted to OS 9, copied files to a laptop over the network, pulled out the Jaguar install disks and repartitioned the drive to include one partition <8Gb in size, installed the OS there. All's fine now, just have to hassle with moving all those files back and testing.
I could have used a repartitioner (FWB Partitioner Tool for OS 9, <a class="jive-link-external-small" href="http://">http://www.publishingperfection.com/fwb-software/fwb201/, other dynamic partitioners are available for OS X) to make the < 8Gb partition within my OS 9 boot and avoid deleting everything on the drive in the process. But I didn't figure this out until I'd already backed everything up. Plus, I didn't want to pay the extra bucks and wait for shipping. So I used Disk Utility on my Jaguar install disk to create my < 8Gb partition for Jaguar. Now I have a fresh install. But I'd rather not have had to spend the time figuring all this out!!

IMac G4 won't boot after install of iTunes latest update

I just updated my iTunes software via download. I have the iMac configured to ID when new updates are available. After download I selected the "restart" option. Computer shut off and upon power up will not proceed past blue start up screen with the progress bar and "starting MAC OSX...." text. I have tried power down/power up. It has been at least an hour and still on blue screen. I have never had a problem in 5 years. Any ideas?

Hi Dean, and a warm welcome to the forums!
Unbeknownst to you, you had problems on your HD before the update.
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot.
The usual reason why updates fail or mess things up, is if Permissions are not fixed before & after every update, with a reboot... you may get a partial update when the installer finds it doesn't have Permissions to change one obscure little part of the OS, leaving you with a mix of OS versions.
Some people get away without Repairing Permissions for years, some for only days.
If Permissions are wrong before applying an update, you could get mixed OS versions, if Directory is the slightest messed up, who knows!
If many Permission are repaired, or any Directory errors are found, you may need to re-apply some the latest/biggest updates again, or even do an A&I if you have enough free disk space.
An Archive & Install, which gives you a new OS, but can preserve all your files, pics, music, settings, etc...

Updating
Certain steps appear to minimize the risk of an update producing problems.
Number one is to make sure you have a bootable clone backup of your computer in case you do need to back out of it again. This is the only guaranteed way of not having to worry about the results of an update.
Some like to boot from their installer discs or an external backup and verify (and if necessary repair) their internal drives as well as drive permissions. This is done with Disk Utility. You can verify a drive while booted from the same drive but sometimes this produces spurious errors. Repairing a drive (if necessary) has to be done while booted from another disk. Permissions repair can, and is probably best, done when booted from your internal drive.

You can also go to the step of booting into safe mode to do the install.

[Safe Boot takes longer than normal startup|http://docs.info.apple.com/article.html?artnum=107394]
I like to download the update onto my computer and install it from there rather than let Software Update do it. I know a few people who had problems with doing the update via software updater found a manual install to work.
Repair permissions again afterward.
It helps to only install one update at a time and to run the computer for a while to make sure it is behaving well.
The more cautious even like to unplug third party peripherals (see [comment by BDaqua|http://discussions.apple.com/message.jspa?messageID=9040746#9040746]).
Almost all of the above steps (except backup) have been questioned as to necessity because probably many people have done successful updates without doing them. I say they can't hurt, they can very likely do good (especially if your computer isn't regularly maintained), so why not do them to be safe.

MacBook Pro Won't Boot after Firmware Update

So I just upgraded to a MacBook Pro which came in the mail yesterday. I removed the Apple-installed HD and swapped it out for a bigger, faster HD. I installed OS X from scratch, imported everything from my Time Machine backup during the Setup Assistant, and then started installing updates. Everything was running swimmingly until the last updates.
What happened is when I rebooted my MacBook Pro and logged in after a series of updates, I got presented with both a Bluetooth update and a Firmware update at the same time. Both required a restart so I thought I would kill two birds with one stone. I installed the Bluetooth update, and then when it asked to reset I installed the Firmware update instead. However, the firmware update didn't behave as advertised because instead of shutting the MacBook Pro completely down, it restarted and then started installing the firmware update.
Ever since the firmware update (which I think installed correctly but don't know how to verify), I cannot boot my MacBook Pro. Using the OS X install DVD I can view my firmware version using System Profiler, and the number it is reporting is MBP53.00A.B03.
I have tried booting in verbose mode to try and get a feel for the problem, and it eventually hangs on an infinite loop saying something about not being able to find something on disk0s2.
I also thought I would fix the problem by doing an Archive and Install, but it quit at the very beginning of installing with the error "unknown error".
Also I thought I would format the disk with Disk Utility and then try installing again, but Disk Utility reports that it in unable to unmount the volume.
Any help you can provide would be greatly appreciated. Thanks!
-- Update --
Remember how I'm unable to unmount the drive? I force unmounted it and then used Disk Utility to repair the volume, but still no luck.
I think the key to the problem is this new HD I put in runs at 3 Gbps. I think I read somewhere that the new MacBook Pro's don't support that.
I think next I should try swapping out the new HD in my MacBook Pro with the one it originally came with. What do you think?

I, too, have a brand new MBP 15" that I put an Intel X25 in. At the 1.5 (Prior to Firmware Update) setting, it worked fine. I rant the Firmware Update, all looked fine, but the drive is no longer able to be seen.
Flash the PRAM, per other suggestions to no avail. Boot off of the DVD and disk utility nor Profiler sees the drive.
Replace the drive with the stock that came with the MBP (which I had never even used) and it works.
Put the Intel X25 into a Windows machine and it works fine. Reformatted it (in windows) and put it back into my MBP. Still not able to see it (from the Disk utility after booting off the DVD).
Intel's firmware for the drive says its up-to-date (new drive) and if I attempt to "re-run" the Mac Firmware Update, it says that the machine is already up-to-date.
Seems odd that it worked before an now it doesn't. Also seems odd that the X25 works in other machines. And that my MBP works just fine with the stock Hitachi 7200 320GB drive.
Ideas? Intel says to call Apple Support. Not sure what I can say to them.

System won't boot after switching to higher performance

I recently installed snow leopard on my 2009 MacBook Pro. Things have going going very smoothly so far. However, I have had one setback. When switching to a different energy saver mode (either from higher performance to energy saver or vice versa), the computer won't boot back up. It will sit at the blue screen with the spinning wheel. Sometimes the wheel will freeze and the dock and my desktop will show up, but the computer is frozen. This forces me to do a manual shut down. This happens about every other time I try to boot my system into a different energy saver mode. Anybody else have a problem with this?

Hi DPer & welcome to the forums...
Try resetting some of the hardware involved (PRAM~NVRAM). See this Apple KB for details, etc.:
http://support.apple.com/kb/HT1379
Can't hurt to try, and apparently this has helped others recently.
If still no joy, did you update via Software Update or did you download the combo? If you used Software Update, get the Combo updater instead and re-apply:
