Won't boot up after attempted security download?

I have a G4 and was attempting to download the most recent security update. I got an error after the download and it went into my trash. I thought I would delete it and try to download again. I emptied my trash and the computer got froze getting the files ready to be deleted. So I restarted. Now, the gray screen comes up and stays up with the black spinning wheel. I have tried to restart with the start up disk (holding the c key down) and it is still gray, but no spinning wheel. I have tried to restart with the option key, same thing. I've tried every variation of holding keys down to no avail. It's now been like this for two days. I'm afraid to turn it off. Is there any way I can get it back to normal without having to bring it in to the store? : ( Thanks for any assistance.

Do you have your keyboard plugged directly into the computer chassis? Sometimes plugging it into the display means the Mac does not see those "snag Keys" at Startup.
Holding the shift key immediately after the startup chime should cause you Mac to check its disk and then come up in "Safe Boot" mode, with few extensions loaded and most stuff set to defaults.

Powerbook G4 (OS X 10.4.11) won't boot up after latest security update

My G4 failed to reboot when restarted after latest security updtate.
The gray screen with apple logo and rotating gear stays on forever.
I tried booting in safe mode but same thing occurred.
I was able to boot in single user mode and run fsck -yf and it ran fine.
Then when I tried to boot again, same thing all over again.
I am guessing there must be some problems with new updates in the start-up folder or something. But I am not sure how to get rid of the files related to the new updates. Your help would be really appreciated. Oh, I was also able to run disk utilities application when I inserted Mac OS X installation dvd and booted from it. Then when I try to boot from HD, the same thing all over again...

I just spent a good 3 hrs or so trying to figure out why my imac running os x 10.4.11 wasn't rebooting after I downloaded the latest security update 2009-001. I finally got it running again after browsing the many helpful comments from past rebooting issues. Here are the steps:
1. On another computer, you'll have to download the security update that you believe froze your mac. In my case it was the 2009-001 update.
2. Save this file to a usb key, or in my case, to my LACIE backup drive.
3. Once downloaded, connect the USB key or backup drive to your mac.
4. Insert your install disc that came with your mac. (I installed disc 1)
5. Power down your mac. ( I did so by pressing and holding the power button on the back)
6. Press and hold the 'C' key on your keyboard as you restart your mac.
7. Let go of 'C' as the apple logo and spinning wheel come on. The start-up disc should start to run.
8. Choose your language.
9. At the top of your desktop you'll see 'Terminal'. Start it.
10. at the prompt, type "mount" to see a list of your volumes (in my case, the volume was LACIE).
11. type "find /Volumes/nameofyourUSB/*.dmg" Ex. "find /Volumes/LACIE/*.dmg" (This step will give the path of your update).
12. type "hdiutil attach /Volumes/nameofyourUSB/pathoftheupdate/SecUpd2009-001Intel.dmg" (Note the space after hdiutil AND attach)
13. type "/Volumes/Macintosh\ HD/usr/sbin/installer -pkg /Volumes/Security\ Update\ 2009-001/SecUpd2009-001Intel.pkg -target /Volumes/Macintosh\ HD" (Note the spaces again. Took me a few tries before I finally got it. If you get it right, you'll notice your hard-drive start to be active. Let it do it's thing before you exit Terminal.
14. Exit Terminal.
15. Go to 'Utilities' at the top of the desktop, select 'Startup Disk', and choose your OS (in my case, OS X 10.4.11).
Good luck!

Please Help! Macbook won't boot up after attempted Leopard install (Wont bo

Ok so I'll go through EXACTLY what has happened to my laptop in the past day.. please note that the laptop was NEVER moved from the desk while this has all happened. Also a couple other things you should know.. I had Applecare, but 6 months ago when i sent it in to replace the harddrive -- they said they found some water damage, and it would cost $700 to replace... so i just put in the harddrive myself for $50, and it has worked fine since... So I'm pretty sure I can't turn to Applecare anymore...
Alright...
Yesterday
One of my memory sticks went bad on me... (i had 2- 1gig sticks.) I took the bad one out, and the computer seemed to run fine on the single stick of memory.
Last night
I started to install leopard as an update over 10.4, seemed to work fine, though it was slow -- and finally i got to the leopard installation complete thing (please reboot the computer)... so I did...
It starts loading up... shows the mac symbol with the loading circle thing... but wait, Oh ****, i was probally was supposed to take out the cd... So i turn off the macbook by holding down the power button... and I eject the cd, and then try to start it up...
Not loading... ****.
So after some mulling i decide, alright -- i'll reinstall again...
I boot to the cd drive, choose my options, start the install, and go to sleep..
This Morning
I wake up.. the install hasn't moved at all... It's still at the same place where i left it..
****... so again I manually shut it off, and try and restart to boot from the CD again..
NO GO....
If I hold down C to boot from DVD
The computer attempts to read the disk.. CD drive seems to power down.. then try again.. Then it ejects the cd, and goes to the Apple logo with the spinning circle, but never loads. I've tried it with My old 10.4 disk, and the new leopard disk. Same result on both. neither disk seems scratched either.
If I just boot up regular
It goes to the apple logo with spinning circle.
SOOOO...
I tried resetting the PMU, and PRAM
Is it likely that it is my superdrive gone bad, at a horrible time? If so I guess i'll just buy one on eBay and replace it myself. Is there any way to test it?
Could there by another problem wrong with it?
Please help me troubleshoot this! I'd be very appreciative -- I'm a poor college Computer science student that needs his computer to work for his classes.
Thanks All!

Could there by another problem wrong with it?
Yes. You need the two RAM modules, or at the very least the remaining one RAM module must be for sure securely seated. If not securely seated with only one module, the result is as you've seen.
i was probally was supposed to take out the cd...
No, not necessary. After that, the very delayed loading was totally normal, sounds as if you were just impatient.

Oh, and check the AppleCare agreement, as to the best of my recollection, you can should be able to get a refund, pro-rated for time left.
Check how full your hard drive is now. I'm not clear if you've yet erased your HD or how many systems you've installed - if not erased perhaps it's full up.
A PRAM reset should allow you to boot from the install disc, access the Install Discs's System Profiler, and see what things look like. Also, you should be able to boot to the Apple Hardware Test - while you do need a working optical drive to do so, you don't need any hard drive at all, and it doesn't sound like either one has been lost.

Help! iBook won't boot up after latest security upgrade....................

I have an iBook G4 12 inch screen mac. I have recently updated with the latest Apple security update (15/9/08)Since installing the update my iBook has failed to boot up successfully. There is no start-up chime and the boot stops at the grey screen with the Apple logo and goes no further. I have tried safe mode, won't go there, have tried various other tips, holding down various keys on start-up, all with no joy! Does anyone have the same problem and does anyone have any answers?! Thanks in advance!
Jim

Thanks, Cornelius. I am just afraid now, is it safe or should I forget about reinstalling the most recent update? It is moot right now though anyway, because I still can't get my computer to fully boot up. At least attempting to book with the OS 10.5 disc in the drive it does not power down, but it is getting stuck for a long time (over 30 minutes) on the gray startup screen with the apple and the DVD drive repeatedly spins and stops, then finally just seems to stop spinning and gives up.

IMac won't boot at first attempt

Hi
Recently I've been experiencing that my intel iMac won't boot at first attempt and I have to powerdown manually and then try again. Second time it boots just fine. It's usually in the morning (been shut off for the night), but not always. I've tried disc utility from the install dvd, have repaired permissions and reset the nvram and everything seems just fine. The thing is, this has happened after the 10.4.8 update as far as I can remember. Does anyone else see this or is it a coincidence and some other problem?
Any thoughts would be appreciated.
Best regards

Oups, sorry about that wrong quote - I've been reading to many discussions lately
I've done all sorts of things today and I'm kind of curious to what is going to happen tomorrow morning when I boot up the mac. To sum up, here's what I've been doing:
Installed 10.4.8 manually, downloaded from: http://www.apple.com/support/downloads/macosx1048updateintel.html Read somewhere that the stand alone installer might help.
I ran repair permissions right after and got this:
Permissions differ on ./usr/standalone/i386/boot.efi, should be -r-xr-xr-x , they are -r--r--r--
Owner and group corrected on ./usr/standalone/i386/boot.efi
Permissions corrected on ./usr/standalone/i386/boot.efi
The privileges have been verified or repaired on the selected volume
Ran repair permissions again to check - all was good
Enabled automatically login in the accounts menu in user prefs - someone suggested me to do this, but I'm not sure what that might do, but hey, I'll give it all a shot.
Changed resolution and then back again to highest possible. Apple suggests this when the problem occurs on the 17" iMac.

Unplugged power cord for 30 secs and reset smu (G5 article/idea though)

Used Onyx to delete the content of library > caches which I read somewhere could perhaps help.

My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard (via my MacBookPro), either from the HD or DVD drive. Can't get it to run Hardware Test. Disk Utility says disk OK - files are there. What can I do?

My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard. I erased and re-installed by putting the iMac in Target Disk mode and usin my MacBookPro as the host. But after numerous attempts I still can't get it to boot either from the HD or DVD drive. I just get the white screen after the wheel stops spinning. I can't get it to run Hardware Test - just get the white screen. If I use Disk Utility via my MBP it says the disk appears OK. All the Snow Leopad files appear to have been installed. What can I do?

Perhaps you installed the wrong version OS X onto the iMac, you can't use the disk from another Mac.
clean the disk.
If it's not working then use this method to create a bootable 10.6 USB from the iMac machine specific 10.6 disk or the 10.6.3 retail disk on your other Mac, use it to boot the iMac with.

HT1926 I keep getting the following message after attempting to download and install the latest update for iTunes: missing MSVCR80.dll. error 7 (windows error 126)

I keep getting the following message after attempting to download and install the latest update for iTunes: missing MSVCR80.dll. error 7 (windows error 126). Anyone else having this issue? How do I get iTunes back in working order?

Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)
Remove all of these items in the following order:
iTunes
Apple Software Update
Apple Mobile Device Support (if this won't uninstall move on to the next item)
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.
Please note:
Some users may need to follow all the steps in whichever of the following support documents applies to their system. These include some additional manual file and folder deletions not mentioned above.

Mac OSx won't boot up after update to 10.6.7?

Mac OSx won't boot up after update to 10.6.7?

Hi Mike
This is called a kernel panic, similar to s 'blue screen of death' on Windows. When you say you reinstalled 3 times, do you mean the OS or the Update?
When does this kernel panic appear? You may have a hardware issue if it's happening on boot.

You will have to force the iPad into recovery mode and data will be lost unless you have a backup.

OSX cannot boot-up after installing Security Update 2008-008

Hi Everyone.
I'm using a MacPro 2 x 2.66Ghz Dual Core Intel Xeon with 3GB RAM with Tiger 10.4.11.
After installing Security Update 2008-008, my OSX was not able to boot-up. The screen shows the Apple Logo and the spinning grey gear wheel. It stayed that way for several hours.
I finally switched it off and re-installed OSX 10.4.8 using the Start-up disk that came with my MacPro.
Now I've updated the OSX, all the software & updates EXCEPT Security Update 2008-08. My MacPro works fine now.
Was Security Update 2008-008 the cause of this problem ?
Sincerely,
Azman

Was Security Update 2008-008 the cause of this problem ?
Probably not directly. Very likely something was not quite right on your computer before the update and the update happened to exacerbate that. A number of people feel that optimizing the maintenance of your computer before doing the update and doing the update under controlled conditions minimizes problems.
There's been recent discussions as to what steps are truly necessary in doing a minimal problem update.
I think #1 to which all agree is to make sure you have a backup of your computer in case you do need to back out of it again.
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 also go to the step of booting into safe mode to do the install.
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 also helps to only install one update at a time and to run the computer for a while to make sure it is behaving well.
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.

Computer won't boot up after installing SIIG card

Hey Everyone,
I having problems with my SIIG FireWire 2-Port PCIe DV card that I've installed into my PowerMac G5 Quad. With the card installed the computer will not boot up, which is the same thing that happened with my previous two models of the card. I installed a new card yesterday and it worked fine all day, but after shutting the computer down for the night and then restarting it in the morning I am experiencing the same problems. The light on the front of the computer turns on, but the screen does not, and after about a minute a loud fan noise comes one. I have the card installed in Slot 2. In Slot 1 I have a ProTools HD card and in Slot 3 I have an AJA Kona LHE card. Even with all of the cards removed the computer still does not boot up. Anyone seen this problem before? Any help or information anybody can offer would be greatly appreciated.
PowerMac G5 Quad Mac OS X (10.4.8)

Hi, I had the same problem with my dual core G5.
I installed the card and my computer won't boot up. The screen stays gray and the fan keeps spinning.
I contacted SIIG and they said the card is defective, which, I doubt it is.
I then returned it for a refund.

Since installing Mac OS X Snow Leopard my macBook pro does not allow Adobe Flash plug in even after attempting to download. Any advice what to do? Tks

Hello,
Since installing Mac OS X Snow Leopard on my MacBook Pro, I cannot use Adobe Flash. Each time i attempt to download Adobe i get the same message "blocked plug-in'. Any ideas?
Tks

alisel,
the latest version of Adobe Flash Player that runs on Snow Leopard (or newer versions of OS X) can be downloaded here.
Once you’ve installed it, you might need to check Safari’s Preferences, in the Security tab, to make sure that the “Allow Plug-ins” checkbox is checked.
