System Updates, Now Won't Boot

I did four recommended system updates yesterday, two being Security and ITunes. Now my MacBook won't boot, even in Safe Boot mode or from the disk. Just the blue screen and the circle. I have it connected to another computer so I can see and get into the HD that won't boot but I'm not sure how to bring it back without deleting other files that have nothing to do with it. I'd like to return my system to how it was before I did those updates. It does not have TimeMachine. Is there any way to return to "yesterday" before the updates?
Thanks from Gina

You won't be able to return to the "yesterday" configuration unless you have a backup.
I assume you are using Target Disk mode to connect the MacBook to another Mac. If so, use Disk Utility on the other Mac to run the following: first Repair Disk Permissions. If that doesn't correct the problem, then run First Aid.
 Cheers, Tom

Just did the latest system updates, restart & won't boot

just did the latest system updates, and keep on getting grey page, apple logo & spinning icon??

If you read any of the posts about wireless lack of connectivity, I think you will discover that your problem is related to their problems. Some people have Kernal panics immediatley, and if you have a wireless setup and the machine is trying to connect wirelessly, it kernal panics and doesn't continue. If this is not the case, write back so that further troubleshooting can take place. By the way it would help if you posted whether your MacBook was a Core2 duo (Broadcom wireless chipset) or Core Duo (Atheros wireless chipset) in addition to the type of router you're using. This gives technicians info they need to duplicate the problem.

MacBook pro kernel panic, now won't boot. Am I doomed?

My MacBook Pro 15" (bought in Jan 2012) just had a kernel panic and now won't boot up.. Am I doomed?

No, it doesn't necessarily mean the hard drive is toast. You can start by doing the following:
Boot into Safe Mode then do this:
Repair the Hard Drive and Permissions - Lion
Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. 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 then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
If the drive is OK and you can repair permissions, then see if the computer will boot up normally. If it doesn't boot up normally then reinstall OS X:
Reinstalling Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. 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 main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

WinXP booted after BIOS update cleared RAID setting, now won't boot in RAID mode

I updated the P965 Platinum BIOS to 1.7 and my system stopped booting. After much experimentation I discovered it would boot if I unplugged the monitor and mouse, so I was able to "upgrade" to 1.6, and it's working again. However, the first time it booted blind with 1.7 it got all the way to Windows before I realized what happened.
My system was set up with a RAID1 pair, but the BIOS upgrade cleared the SATA mode to IDE, and it booted Windows before I changed it back. Now Windows won't boot when I set it to RAID. It complains <windows>/system32/hal.dll is missing or corrupt. It seems to work (mostly) when I put it back to IDE mode. How do I get it back to RAID1?

Battery died while updating to OS X 10.5.2, Now won't boot!

Dear all,
Last night I went to update my PowerBook from 10.5.1 to 10.5.2, along with a couple of other updates that Software Update had downloaded. Half way through the installation my battery died, and now with the mains plugged in, the computer won't boot at all. I get the initial white screen with they grey apple logo in the middle and a spinning loading icon.
Is there anything I can do to revert it and get it to boot up?
I have a time machine backup from about a week ago, but have some work I did yesterday I would really rather not lose if at all possible!
Many thanks in advance,
Jude

Lesson learned: never update on battery.
If you can boot your computer with your OS disc, and if you have enough free hard drive space, you can perform an Archive and Install. This way you lose nothing but the 90-180 minutes it will take for the OS to install.
If it won't boot off the CD or you lack the drive space for an archive and install find another Mac user and mount your computer's drive on their computer using FW target disk mode.

Hi guys I'm really in need of some help. I have an IMac I3 for a while now I've been having a problem of my machine refusing it shut down , it goes to a blue screen with a spinning wheel but doesn't shut down. And now won't boot from install DvD

Please some one help me ...
A) my mac won't shut down with external HD connected (if it's been used)
B) there are disk permissions that can't be fixed SUID stuff ..
C) I have now verified the Mac HD and it tells me it's corrupt in bold red writing and to start up from install DVD
D) it won't boot from DVD so I cannot run the repair , initially the machine was spitting it out on start up , now it appears to be attempting to boot off DVD , well it sounds like it is .... BUT it's hanging with the Mac Logo and a wheel ... For um .... 30min now...
E) weirdly when OSX is booted off the hard drive , it won't recognise the Install DvD or the applications one... It just spits them out....
I had an old PPC 17" and it was a beaut .... Never had a single problem with it ...
I bought this one December 2010 and it's been nothing but issues for a computer in excess of £1000 I'm extremely disappointed ... And weirdly the shutting down issue started when it was a week out of warrantee ... I feel conned and am almost at the point of throwing it at a wall and buying a PC

Ok so I've done what you said and this is what it's come back ....
I don't know that these are the errors , but they're the things which don't look right ...
Throughout the shut down there is a recurring line ;
It says ;
Com.apple.launchd 1 0x100600e70.anonymous.unmount 301 PID still valid
Then there are 2 more which I think are related ;
Com.apple.securityd 29 PID job has I overstayed its welcome , forcing removal.
Then the same with fseventd 48 and diskarbitrationd 13
Oh and on Launchd1 : System : stray anonymous job at shut down : PID 301 PPID13 PGID 13 unmount...
Then the last process says "about to call: reboot (RB_AUTOBOOT).
Continuing...
And stops ...
Hope this means something to you ... Thanks again for your help so far :-)

Imac G3 had clean install OS 10.1; can't install 9.2; now won't boot at all

Hello,
I was given an older imac G3--has 176 mg ram; 6 gb hard drive. Due to its small memory and the fact my daughter just wanted it for games, I decided to only install OS 10.1, instead of OS 9.2.2 and OS 10.1.5 which I have on my G4.
Then, I found that most of my CD games (no internet access) need Classic to run. So, upon inserting my OS 9.1 disk to install that, I got the message that the firmware needed to be updated; then an error saying I needed installer 4.5.5.
Two questions:
1. How do I get around the fact that my firmware needs to be updated but when I boot from a locked disk, I get the error message that firmware updates can't take place due to locked disk.
2. Now, I can't get it to boot at all into OS X or any disk in the CD drive--I get a screen with a little script that says, "failed to boot, etc., Apple Firmware 3.0 3f built 12/__98
then (not exact text)
0 >boot MAC-PARTS: specified partition invalid, etc.
can't open ide1, etc.
I hooked it up to my other G3 imac and my G4 via ethernet cable but since there's no system accessible, I can't turn on file sharing/Apple talk, etc.
Hoping I'm not the only night owl going round and round with these kind of problems. Any help would be much appreciated.

If you don't mind wiping the hard drive, boot from the 10.1 installer disk and install the 9 drivers:
http://docs.info.apple.com/article.html?artnum=75275
Then find out what CD came with the Mac by first identifying it:
http://docs.info.apple.com/article.html?artnum=58669
And then looking at this article:
http://docs.info.apple.com/article.html?artnum=25517
If it came with 9, get the original CD that came with it to install Mac OS 9.
If it came with Mac OS 8.6 or earlier, get a retail 9 CD which looks like
Do a clean install using
http://docs.info.apple.com/article.html?artnum=58176 as a guide once you have the correct 9 disk.
Then install the firmware update that corresponds to your Mac:
http://docs.info.apple.com/article.html?artnum=86117
And then I would not even bother with 10.1.5 anymore and get 10.2. Repairing issues with 10.1.5 is difficult. 10.2 installer disks which work on that machine once the firmware is updated look like

Macbook Pro 2010 froze, now won't boot.

Hey all,
I have a Macbook Pro that i got in 2010. It has been a great machine. I have done a couple of upgrades on the ram and hard drive. For a while there were not any problems. But last week my computer froze up, app by app, till the whole computer was unusable. Then I restarted the computer and it said that the hard drive was having problems. I tried doing all the repairs on the hard drive, eventually replacing it with a SSD because I thought the drive was dead. So I plugged in the SSD and it had a hard time writing to it the first time I booted the computer with internet recovery, but when I tried it again it allowed me to install OS X Mountain Lion again. Got it installed, then the exact same thing happened to me, each app froze, till the whole computer froze, now the machine won't boot, or even let me do any of the keyboard boot options. It just sits at a blank screen and gets hot. Any ideas? I really need my computer to be working right now and i don't have the money for an additional one.
Thanks

Yes, unfortunately, yet another Apple device failure. Question marked answered because repaired under warranty. BUT:
It is embarrassing as a Mac bigot to have had this problem and in the few months since ALSO had:
- iMac 24" (condensation inside screen, never happened to any other company's monitors)
- iPhone 3GS white screen of death
and before this:
- MacBook Pro 17" defective graphics, motherboard replaced
- PowerBook G4 17" defective sound system, motherboard replaced
- eMac G4 700, screen fizzled into showing 1/4 display size in center, thrown away
- PowerBook G3 500 FW defective, whole machine replaced
- PowerBook G3 300 defective, machine replaced
- PowerBook Duo 280c defective keyboard, replaced
and I can't even remember past that.
Can't make fun of ugly clunky Dells or HPs anymore after this experience.

Ongoing System Freezing problems, won't Boot from CD, HELP!

Three weeks ago, my system started freezing after about 20 minutes of use --completely stuck while not running anything more taxing than internet browser-- and then the infamous fans kick on and the thing sounds like its going to take off. I eliminate possible conflicts w/ peripherals with no improvement, back up my files and trot 100+ miles to the nearest Genius (which is questionable). They diagnose it as the power supply/logic board issue, replace both --the second time that they have been replaced-- and send me back home, smiling blissfully.
Until I plug it in, and it does the same thing. I live with it for a week, then load it back up for another 200+ mile roundtrip back to the same Genius, who keeps it for a week, claims that he has run every test known to Apple and can't find anything wrong. His suggestion: new surge protector. So I make the 3rd trip to go pick it up, buy the heavy duty super charged surge protector, plug everything up, and ..... you guessed it. Same ol' same ol'.
So torn between crying and cursing, I get on the phone and call apple support. After close to two hours on hold in the Que (I could have drove to the Apple Store in less time) in which I speak to a live person who transfers me to another who cuts me off as soon as they pick up the phone and I have to get back in the que to repeat the exercise in patience, I get a hold of someone that says, well it might be hardware or it might be software-- try running the hardware test first and if that doesn't give you an error, reformat your hard drive, reload the OS, and then your software and see if that doesn't fix it.
So now, I really am about to cry... but I suck it up and start to do the deed. Except.... I can't get the hardware test or anything else to boot from the CD. I try my disk, I try my son's disk. Nada. Zip. Won't boot at all from the CD. One disk says "hold down the C key," one says "D key." Doesn't matter, neither works. It will restart but forget the CD.
Here's the help part: what next? Is this an indication that its a software problem? Is there something else I can do? Or am I doomed to make another 200+ round trip to the Genius Bar? Frankly, I think I'm ready to drive in the other direction to the next closest Apple Store, but...
I'm so tired and frustrated!! Out of the last 14 days, this <edited by host> has been in the service department for 9 days and I've logged 700+/- miles trying to get it fixed. Between the lost time cost, gas and repairs (the $800 for the most recent repair and the $1000+ the first time around that thankfully were on Apple), I could have bought a top of the line new Mac and still had $$$ left over for a nice dinner!
PLEASE! Any suggestions?!

Hi Stellaadora-
A call to Customer Relations at 1-800-767-2775 may be useful. Be firm yet polite and explain the situation and have them open up a case number. This is not Apple Service,but more like the overseers. It may also be useful to research the Consumer Protection Laws in your state. Three attempts to repair it in MA and you get a new machine.
My guess is that they will have you try someone else. I know I would.
Certainly the store is not duplicating your 20 minutes of web-browsing. It could be something to do with networking. Have you tried disconnecting from the internet and doing something else for a while to see if it still locks up?

Phone kept getting hotter and hotter after update - now won't turn on

Well, seems that my phone crapped out. The mandatory system update that seemed to take forever to load and then install. Afterward, the battery would get the life sucked out of it in minutes while getting hotter and hotter to the touch. Now it won't even turn on. Grrrrrrrrrrr
Has anyone else experienced this? Any suggestions on fix?

@gaieegail,
Believe me when I say I feel your pain! I have the same phone and had the same issues after the update. But don't worry because I'm here to help!
What worked for me was performing a hard reset http://bit.ly/nExWmP after the update. I know it can be inconvenient but necessary after such a big update like the ICS.
I noitced a big difference after the hard reset and I'm confident you will too. Just make sure you back up your phone before the hard reset so you don't lose anything you need.
Keep me posted if you need further assistance.

Pismo now won't boot into X (but runs 9.1)

I originally upgraded PBG3(FW)(pismo) to panther about a year ago. All was well and it worked without any problem.
Then at the suggestion of software update I did one of the security updates (to be honest i can now no longer remember which one) and after that it crashed and refused to boot.
It will not boot from my panther CD - sometimes gets as far as the grey apple and spinning disk, then stalls.
It will boot from a backup 9.1 CD and I can re-install 9.1 on the HD, which then boots and runs normally (wow its fast).
From within 9.1 the panther CD mounts and verifies normally. In startup disk it is greyed out so i can't chose to start from it. If I launch the installer it tries to restart but won't and gives an error to the effect of not being able to startup from the startup CD.
It will not boot from a clone of my PM G4 installation from a firewire HD.
The panther CD will startup the G4 (so it must work) and I can install panther on the pismo HD when it is in FW target disk mode. But the pismo will still not then boot from this install.
Its as if something in the update stopped the poor pismo from starting up from any version of X. No other hardware changes made between it being OK and now refusing to boot.
Any help very gratefully recieved !

Hi Jon:
Good call on removing the RAM, which is often a culprit of kernel panics, and you're right, Panther does need at least 128MB to run. You could try another stick of RAM (I'd recommend Kingston or Azen)....
I've installed Panther on close to 50 mac of various flavors in the last two years, everything from 350 MHz iMac to a dual 2GHz PowerMac G5, and have rarely encountered a problem that couldn't be resolved with a simple hardware change (RAM, optical or hard drive). Right now, as it turns out, I'm having problems with a 350MHz iMac. Panther installs ok, all the updates go ok, all the installed apps run fine, but as soon as I try to change the screen saver, it freezes. I've wiped the drive, written zeros, and reinstalled, and both times I get the exact same thing. I've swapped RAM, which makes no difference, so I'm about to try a different hard drive.
Let us know how replacing the mach_kernel file goes, and good luck!

In OSX now won't boot back to OS9 Help!

Hi Folks! I've done this before but it's been a while and I've forgotten how to resolve the problem. I usually use OS9 on this computer but i booted into X and then used classic and now it won't boot back to OS9. You can select the OS9 drive in the startup panel but it just boots back to X. Using an option boot the OS9 drive doesn't show up. The only thing I did was startup classic using the system folder on that separate OS9 drive. Why would starting up classic render a perfectly good boot drive inoperable. I ran Diskwarrior on it to make sure the directory was in good shape. The OSX is one one drive and the OS9 is on another. Tom

Hi Tom-
Do you need to rebless the system folder?
