Mac book not starting up after update

after installing the latest update on Mountain Lion my Retina MBP dies after trying to boot. any help would be great.

Hopefully you have a backup. Your hard drive may be failing. I'd try a few things:
if you have any peripherals, like mice or keyboards, unplug them and try again.
try a SMC reset Intel-based Macs: Resetting the System Management Controller (SMC)
a safe boot Mac OS X: What is Safe Boot, Safe Mode?
boot to your recovery partition and repair your hard drive and permissions When to Run First Aid in Mountain Lion's Disk Utility - For Dummies
if that doesn't work, try internet recovery OS X: About OS X Recovery
if you can get your computer booted in one of the recovery modes, but it can't be repaired successfully enough to start into the regular boot partition, you may need to erase the drive and start over with a clean installation.
You might be able to get your hard drive to mount in target mode on another mac, which would let you back up any files that you want to save on the drive: OS X Mountain Lion: Transfer files between two computers using target disk mode
if you can't get any of this to work, then the drive quite possibly is failing, and should be replaced.

How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X 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 Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) 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. Now restart normally.
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. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

New Macbook Pro does not start up after updating...HELP!!!

Hi,
My new Macbook Pro does not start up after it got updated. The first time I used it, it was perfect. I updated it and restarted it when it told me to but it doesn't boot. It shows an apple and a spinning circle when it turns on but that's it.
Can somebody please help me?

You should probably post your question in the MacBook Pro discussions:

Not starting up after updates

I just got a G3 iBook 500Mhz 384Mb off ebay, OS10.4.9, which worked fine. So I decided to install some of the available software updates, instead of just letting it be! A couple of iphoto updates, keynote, iweb, java, final cut, etc,went in fine until the 10.4.11 update which would not complete - got to 12% or something and then said an error was detected so it stopped. I stopped doing updates, my boy played an internet game for a wee while, then shut down. Now it won't startup - I get a tone, the spinning gear for 20secs or so, then the blue screen with the white box saying Mac OS X and an empty progress bar, and a while later the spinning beachball appears, to be with me for a few hours. Nothing else. Some suggestions please? (I also have a MacBook Pro, with 10.4.11, if that might be helpful, and while I'm not experienced at computers, I'm quite prepared to try things.
Many Thanks.

Oh.
Ah well. I'll get back to the seller - again. He earlier suggested 1. resetting the P-RAM, 2. resetting the open firmware, 3. safe boot. None of these worked. He then suggested booting from the disc(pirated) and reinstalling. This worked to an extent, but this morning it would not start up again - but it did get as far as the login, then after logging in it went to a background, with an arrow pointer, and no further (I did leave it for over an hour), while last night it did get past that point(slowly) and worked ok.
So, now I'm trying to reinstall again ( a smaller custom install) then I'll delete the most recent previous system folder, and some other apps that came with it (pirated too!!?)
I guess I may (should) buy a retail copy.
Why didn't I just leave it alone???
Any other advice?
Regards
Roger

Lightroom not starting up after updating to CC (2015)

Adobe CC updated my Lightroom CC (2014) to CC (2015) Now Lightroom will not start. I have uninstalled, rebooted, installed again and still does not start up.

Tstoikka did you utilize the uninstall process documented in Install and update apps - https://helpx.adobe.com/creative-cloud/help/install-apps.html to remove your current installation of Photoshop Lightroom? Are you able to install other Adobe Creative applications successfully?

Slim does not start lxde after updating

Hi!
After updating the other night I cannot log in to lxde anymore. Slim gives me
Failed to execute login command
I read my way through the internet for similar threats and problems. I already checked whether my slim.conf is ok. I checked whether X is running ok. And Im not sure if it is.
I did
grep -e "2012-09-19" /var/log/pacman.log
to see what was updated. And it was xf86-video-intel and tzdata and the kernel.
Im running arch on a eeepc 701 with intel graphics. I have Slim and lxde. I can ssh onto the machine from outside.
If I take slim from the deamons in
/etc/rc.conf
I can
startx
but I only get a black screen on tty7 and on tty1 I get
No protocol specified
. And after some time I get
xinit: giving up
xinit: unable to connect to X server: Resource temporarily unavailable
waitiing for Xserver to shut down Server terminated successfully (0). Closing log file.
xinit: server error
I noticed that I didnt have "i915" in /etc/mkinitcpio.conf, so I added that and built iniramfs. But that didnt help the issue.
Maybe anyone cand help me out here?
Thanks for your time!

It definitely sounds like something went wrong with your video update. Can you downgrade to confirm that is the problem? If so, my next thought would be to remove the recently downloaded version from your package cache and re-upgrade.
If downgrading doesn't help, then perhaps my assumption is wrong, then full Xorg logs would be useful. Actually, they'd be useful in either case ... so can you post those (or pastebin them and link to it).

Mac book not starting - renaming of Mac HD

I installed Leopard 7 days ago and have been having no significant problems until this morning when the machine would not start.
The "chord" sound plays, and the Apple Logo on the grey screen shows, along with the little spinning indicator, but it goes no further. I am stuck, and in the middle of Sudan without any real tech support folks anywhere near.
I have one candidate so far for the source of the problem:
1. I suspect that this may relate to my renaming of the hard drive last night. As to why I did such a thing, nevermind that.
Any ideas about how to get the machine to fully boot up? and perhaps rename the drive again to the original?
Juba Brian

Oh! I was hoping it gives you two drives / images, and one of the would be the corrupt one. What this may indicate, i am afraid, is that your boot volume has been somehow corrupted.
Did you rename the boot volume via the "get info" window in finder? Because this should be fine.
The only way to go further - alas - is to wait for the computer disk to arrive. And maybe run disk permissions from the disk (you would need to go past the window "installation language", which then gives you a simplified finder bar, where disk utility can be run from. ). if that then finds a disk called e.g. "WD5000AAKS-41YGA0", RATHER than your own disk (e.g. "jubas very own" or whatever you named your drive), then your volume header is probably corrupted, and it cannot access the info. you could try a "repair DISK", then hopefully afterwards "repair disk PERMISSIONS".

Mac will not START UP after software update. Help?

I just updated my 24" iMac to Snow Leopard and also put on the new iLife package. Everything was working fine, Then i tried to get onto the internet using my Bigpond wifi (usb stick) the software started fine and connected to the internet, but in safari no web page would load. so i clicked on the update software/firmware option for the bigpond wifi usb stick and after several minutes realised everything had frozen. nothing would respond.i held the power button down, it shut down. Now it will not power up. just sitting at the first white screen with the apple and rotating line dial. I have tried all of the stup options recommended iner manual and removed/replaced te ram. still no fix.. Can someone please help?

Try starting the Mac with the original DVD that came with the computer, then run disk utility and repair the hard drive also repair permissions. http://support.apple.com/kb/HT1782

Help! My mac is not starting up after install of tiger.

Just to let everyone know I'm a young girl and I'm pretty useless with computers.
After having a 'invalid node structure' on my mac and fixing it manually, the volume could not be repaired. So I've erased the Macintosh HD 'i think' after it saying 'resource busy' numerous times. I finally had a destination to install Tiger (before there wasn't one showing up) and I installed. Now the computer has installed successfully and is stuck on the white screen with the apple symbol and the loading circle thing. What do i do to make the computer start?
P.S. I used to have leopard. (but i couldn't find the re-install discs. Also the Macintosh HD is repaired and fine. I'm not sure that the OS x is 10.4.2 I guessed because it was tiger.

Hi there, and a warm welcome to the forums!
Do you know the age of your iMac or the exact model, Tiger won't work on the newer ones, like if it came with Leopard or greater.
Try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If that doesn't work report back please.

Apple TV not starting anymore after update

My Apple TV is set on applying updates automatically. When I started it yesterday it showed a message that an update had failed and encouraged me to perform the update manually. I did so in the settings and everything looked normal. The updated was first downloaded and then the installation performed however at the end of this task the Apple TV shut down and now I cannot start it at all anymore. Holding down Menu and Down on the Apple Remote for six seconds does not work either.

If you really want to restore your system [this link|http://docs.info.apple.com/article.html?artnum=61802|How to restore your Apple software] might be of some help... It boils down to this:
*Restore Mac OS X and all bundled applications without erasing the Mac OS X volume*
1. Back up your essential files. This is a wise precaution even though you won't be erasing the volume.
2. Insert the Mac OS X Install disc that shipped with your computer.
3. Double-click "Install Mac OS X and Bundled Software."
4. Follow the onscreen instructions to reinstall all software.

E65 not start-up after updated new firmware

Hi,
Yesterday I conected to PC suite and updated firmware from 2.0.... to 3.0... > Everything went through smoothly. After I restored all information from back up files of PC suite, then I could not use my phone any more. Everytime I try to restart my phone, the message " Phone start-up failed. Contact to retailer "
Could any one help me to make my phone back to work, please ? Thanks a lotttttt

Try the "3 finger deep reset" which is depress these three keys simultaneously "*" "3" "green phone" and then power on phone whilst keeping those same three keys depressed until you hear start-up tone.
This should ONLY be done if the device doesn't power up normally anymore and it wipes everything in the Phone memory that is not part of the ROM.
You will need to restore your data after this.

Computer not starting up after updates

I updated the software on my computer and restarted the computer. When it came back up it said i needed to shut down my computer for the firmware and when i was turning it on, i should hold the power button until it flashed. I did this and the computer will not turn on. I don't have a clue as to what happened and any advice would be great.

Mac book not starting it's showing question mark

Can you help me

That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the Operating System data on the hard drive is somehow corrupted.
Put your install DVD into the optical drive (CD/DVD drive) and reboot. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option key until the Install Disk shows up) until the apple shows up. That will force your MacBook to boot from the install DVD in the optical drive.
When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
If it is, then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions. After repairing use Startup Disk from the same menu to choose your hard drive for restarting from your hard drive.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.
