Stuck on startup screen after 10.9.1 update

so, my app store had been bugging me to do updates for about a month and I finally did them today. Then, Google Chrome kept crashing every time I tried to open it so I rebooted into recovery mode and ran the disc verification. It got stuck on the startup screen, so I tried to restart it again... got stuck on the startup screen again... went back into recovery mode and repaired permissions and now it's been stuck on the startup screen for 1/2 an hour. Help??

Jamie,
Since your wife knows how to use the installer DVD for maintenance, ask her to do a "Repair disk" on the startup drive. (Repairing permissions is something else.) However, also ask her if by 'no effect' she means repairing permissions could not be done or reported no permissions problems with the drive. If the latter, it is good news in that it at least means Disk Utility found a valid system to check permissions on. Anyway, let us know the results of the repair disk step, particularly any messages about repairs that were attempted.
It is unfortunate that you don't have some files backed up but hopefully we can get your Mac back up to speed without losing anything. If they are highly critical files, you may want to consider waiting until they can be offloaded to another Mac using Target Disk Mode or similar techniques, since any write to the drive has some (if generally very small) chance of overwriting data.
Be aware that there have been some reports of problems associated with certain scanners & external drives, & not just with this update. I have no firsthand experience with this, so I can't tell you exactly what they are, but I suggest you disconnect them until the problem is resolved.
Hopefully, these three steps will get you closer to a fully-functioning, bootable Mac, but either way, keep us informed.
Oh, one other bit of advice in the meantime: if you haven't already, give an authentic, Chicago deep crust pizza a try before you leave. I like Pizzeria Uno or Due, but there are others.

27" 2009 iMac is stuck on white screen after OS X Maverick update

27" 2009 iMac is stuck on white screen after OS X Maverick update. How do I get past this White Screen? I have tried to use the PRAM reset, holding down Shift,Command, R, and P after turning off computer then when I turn it on, having those pressed until I see the apple symbol. I only hear one chime. Never get to a second chime. Thank you.

Mac stuck on startup screen after Mountain Lion install

After installing Mountain Lion my Mac restarted and has been on the startup screen (apple logo with loading icon spinning) for the last hour... I'm assuming this means my hard drive crashed during the install? What ***** is this happened when I installed Lion the first time. Wasn't a cheap fix and lost everything.

Similar if not the very same issue with my late 2009 iMac since upgrading to Mountain Lion.
First time I've seen actual script - DOS-like text (well, Linux or UNIX or whatever it is) that only seems to appear from a cold boot.
First time this happened I held down the power button until the system restarted.
Second time around - and from a cold boot - I entered "/exit" at the prompt and the system appears to have continuted the boot process.
Someone in another post added the following:
Open console in Applications>Utilities, check the system log for the date/time of the last problem startup for clues.
...but from this I still coudn't see where the error lies. :/

G4 Laptop stuck on apple screen after 10.4.11 update

Laptop wont get past apple screen at start up after software update installed 10.4.11 from 10.4.10
Any advice or suggestions?

There are no guarantees, but following this procedure when installing updates and upgrades on your Mac will go a long way towards avoiding unpleasant after effects and ‘post-update stress disorder’.
It is also worth noting that it is an extreme rarity for updates to cause upsets to your system, but they may well reveal pre-existing ones, particularly those of which you may have been unaware. If you are actually aware of any glitches, make sure they are fixed before proceeding further.
So before you do anything else:
If you can, make a full backup first.
Turn off sleep mode for both screen and hard disk.
1. Repair Permissions (in Disk Utility)
2. Verify the state of your hard disk using Disk Utility. If any faults are reported, restart from your install disk (holding down the C key), go to Disk Utility, and repair your startup disk. Restart again to get back to your startup disk.
At least you can now be reasonably certain that your system does not contain any obvious faults that might cause an update/upgrade to fail.
3. Download the correct version of the COMBO update from the Apple download site. If your car runs on gasoline you would not want to fill the tank with diesel, so don’t try to install the PPC updater on an Intel Mac!
If you prefer to download updates via Software Update in the Apple menu (which would ensure that the correct version for your Mac was being downloaded), it is not recommended to allow SU to install major (or even minor) updates automatically. Set Software Update to just download the updater without immediately installing it. There is always the possibility that the combined download and install (which can be a lengthy process) might be interrupted by a power outage or your cat walking across the keyboard, and an interrupted install will almost certainly cause havoc. Once it is downloaded, you can install at a time that suits you. You should make a backup copy of the updater on a CD in case you ever need a reinstall.
Using the Combo updater ensures that all system files changed since the original 10.4.0 are included, and any that may have been missed out or subsequently damaged will be repaired. The Delta updater, although a temptingly smaller download, only takes you from the previous version to the new one, i.e. for example from 10.4.9 to 10.4.10. Software Update will generally download the Delta updater only. The preferable Combo updater needs to be downloaded from Apple's download site.
Now proceed as follows:
4. Close all applications.
5. Unplug all peripherals except your keyboard and mouse.
6. Install the update/upgrade. Do not under any circumstances interrupt this procedure. Do not do anything else on your computer while it is installing. Be patient.
7. When it ask for a restart to complete the installation, click restart. This can take longer than normal, there are probably thousands of files to overwrite and place in the correct location. Do nothing while this is going on.
8. Once your Mac is awake, repair permissions again, and you should be good to go!
If your Mac seems slightly sluggish or ‘different’, perform a second restart. It can’t hurt and is sometimes efficacious!
9. Open a few of your most used applications and check that all is OK. In this connection please remember that not all manufacturers of third party applications and plug-ins, add-ons, haxies etc, will have had time to do any necessary rewrites to their software to make them 10.4.10. compliant. Give them a weeks or two while you regularly check their websites for updates. This applies particularly to plug-ins for Safari 3.
N.B. Do not attempt to install two different updates at the same time as each may have different routines and requirements. Follow the above recommendations for each update in turn.
Lastly, Apple's own article on the subject of Software Update may also be useful reading:
http://docs.info.apple.com/article.html?artnum=106695
If you are updating Safari (or just have):
Input Managers from third parties can do as much harm as good. They use a security loophole to reach right into your applications' code and change that code as the application starts up. If you have installed 10.4.11 and Safari is crashing, the very first thing to do is clear out your InputManagers folders (both in your own Library and in the top-level /Library), log out and log back in, and try again.
So, disable all third party add-ons before updating Safari, as they may not have been updated yet for the new version. Add them back one by one. If something goes awry, remove it again and check on the software manufacturer's website for news of an update to match your version of Safari. Remember: Tiger up to 10.4.10 used Safari 2.0.4 or, if you downloaded it, Safari 3.0.3 beta. Safari 10.4.11 uses Safari 3.0.4 which is not a beta. If Safari 3.0.4 on 10.4.11 is not the fastest browser you have ever used, then something is wrong!
Moreover, trying to revert to Safari 2 when running 10.4.11 can have repercussions, as Safari 3.0.4 uses a completely different webkit on which other applications like iChat, Mail and Dashboard Widgets etc also rely.
Most errors reported here after an update are due to an unrepaired or undetected inherent fault in the system, and/or a third party ad-on. Two such add-on that have been frequently mentioned here for causing such problems are Piclens and Pithhelmet. If you have them, trash them.

Mac stuck at startup screen after snow leopard install went bad

I have an iMac running on 10.4. I have all the requirements to install 10.6.
i bought the $30 cd to install it, put in the cd and chose install. It went to screen with the black/purple space background and a window that had me choose where to install it to. I think I booted from the install CD.
Chose english, it prepared installation, clicked continue on the install mac os x window. Then i had to choose where to install it. There was only one option (the hard disk) but when i clicked on it, it said i couldn't install it. So I clicked back but I couldn't quit the installation.
When I restarted the computer, it just kept going to the installation and I kept ending up in a dead end. So, I browsed for my available options to restart my computer running on my old OS. I clicked utilities > startup disk > then clicked the hard disk. I thought this would just restart the iMac normally.
The computer restarted, but now its stuck on the start up screen. I turn it on, stays on the apple logo, then it shuts itself off within 2-5 minutes.
Am I screwed? Did I lose all my files that were on the computer? I know I'm an idiot for not backing up all my files on an external hard drive.
How do I get out of this and just use my computer?

Which specific model of iMac do you have? If the installer refused to install, then there must be a reason, such as lack of hard disk space, RAM, etc.
Did you eject the DVD, or is it still in the optical drive? If it's still in the drive, you should try booting from it by turning on the iMac and holding down the 'C' key until you see the spinning radian and see if it will boot from the DVD.
Post back with more info and results.

PB 1.5Ghz stuck at grey screen after 10.5.3 update

Hi, I updated my Powerbook to 10.5.3 yesterday only to come back and find it permanently stuck at the grey screen with the Apple logo. It won't go past this screen. It just stays there forever, and it does not give me any kernel panics. I've read that some others are experiencing this same problem and have archived and installed.
Unfortunately, my friend bought a multi-user Leopard license and gave one to me, but he still has the Leopard disc. What is the best way to resolve this issue? Is there any way to solve this update issue without the disc? Or am I just going to have to wait for him to mail it? Thanks for any help.

IMac stuck at blue screen after 10.6.6 update

Hello,
I updated to 10.6.6 via Software Update today. I left it to install, then rebooted when it asked to. Upon reboot it sat at the blue screen indefinitely and would not get to the log on screen.
I left this for over an hour, and then forced a reboot with the power button, brought it back to the same blue screen though.
I then booted with the disk and tried a disk & permissions repair, but the same thing still happens.
Booting in safe mode also doesn't get to the login screen, just sits there.
Is there any way to recover this installation? Suffice to say i'm mightily pi**ed this update has bricked my machine :/
thanks

i am having the same problem - been going on for over a week - blue screen won't open - used snow leopard disk to run disk utility - disk checks out fine - doesn't help - then reinstalled snow leopard from install disk, starts perfect runs normal, software update updates everything, and it still runs fine for a while then boom, same thing - REPEAT - three times. Hangs up when switching users or starting up.
Today - started again, only this time the reinstall of Snow Leopard fails, says it cannot copy support files. Call to tech says I have to wipe the drive and start over, something is corrupted. Am running right now on a bootable clone on an external hard drive and preparing to wipe my drive. Not happy about it - had not considered that it was the 10.6.6 update causing it... should I wipe the drive or not?

Satellite L500 - System hanging on startup screen after Windows update

Hi,
I'm hoping someone can help. My Satellite L500 is hanging on the blue startup screen after it restarted after a windows update, the mouse arrow is moving, and there seems to be some hard drive activity with some flickering in the system indicator lights. Other than that, nothing? Any ideas?
Thanks,
Denise

It was stuck on the Windows 7 welcome screen, all I had to do was hold the power button down for longer and restart it properly. I was just concerned as they always say not to turn the computer off during an update.
*All good now* thanks anyway :)

Have reformatted my Imac using original discs (installed leopard (10.5)) tried to do the software update but it cant download the itunes update and when it gets to the configure update screen after restart for main update, it just gets stuck. HELP!

have reformatted my Imac using original discs (installed leopard (10.5)) tried to do the software update but it cant download the itunes update and when it gets to the configure update screen after restart for main update, it just gets stuck. HELP!
The configure bar gets about an 1/8 full and then just does nothing. I think its lists the update as combo update? cant remember with out checking.
I have tried to do the disk verify and repair but this has made no difference.
Please let me know what i need to do, I have reformatted the mac just to start over as was clogged with a lot of useless data, I had installed lion (10.7) from the app store previously and now cant seem to find a way to re install lion. I hope I dont need to pay for it again?

If you erased your hard drive, you'll need to reinstll OS X 10.6 Snow Leopard to access the App store. You won't have to pay for OS X 10.7 Lion again. Did you try booting to the recovery partition by holding the command and r keys down? If that's still there, you can reinstall OS X 10.7 from there.
If you're looking to install the current iTunes, you need OS X 10.6.8 at a minimum.
If you're still trying to update OS X 10.5 Leopard, you can download the combo update from here. Download, use Disk Utility to repair permissions, apply the update, then repair permissions again. That will take you to OS X 10.5.8.

My MacBook pro is stuck on white screen after shut down. Now, neither this is turn on nor turn off.

You should be able to turn off your MBP by pressing the power button down continously for about 5-10 sec. When you reboot it you are going to want to enter into a terminal screen. Hopefully the following YouTube video helps: http://www.youtube.com/watch?v=qKOX72xNmbo
