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.

Mac Mini won't boot up after disconnecting it from iMac

I have disconnected my Mac Mini from the iMac I had it connected to, and now it won't boot up when I turn it on. Do I need to hold down a key combination to get it to boot from it's own operating system again?

You should not have to hold down any key to get it to boot to an installed copy of MacOS, though if you hold the option key down, it should take you to the Startup Manager which will give you a list of available MacOS volumes it can boot from. If it doesn't show any, then you don't have a bootable MacOS on your mini.
Are you getting anything on your screen when you are trying to boot, such as a folder with a question mark?

Mac G4 Won't Boot Completely After Restart

I fired up my Mac G4 and ran software update and installed the 10.4.11 update. When I restarted to complete the install the computer gets hung up -- a blue screen with the gear icon turning and turning. It worked fine before I did the update.
I've reset the PRAM to no avail. I've tried booting from the 10.4 install disc but that won'w work either?
Any ideas on how to get this working again?
Thanks!

Open the service door and press the PMU reset button from about a second, then see if the computer starts. (Ref: http://support.apple.com/kb/HT1939)
You can try a safe boot. Press and hold the SHIFT key until you see a message that the computer is starting in safe mode. When you see that message, t=you can let go of the key.
If this gets you a workable desktop, don't try to use any apps--their extensions are temporarily disabled. Try a normal restart to see if everything works.
I've found that by repairing permissions before and after doing a softare update, we've avoided update problems in all our OSX Macs.

Won't boot up after update 10.4.7

Help! I downloaded the update from 10.4.6 (didn't see if it was 10.4.7 but assume it was). Now I start up with a grey screen headed
Panic(cpu 0 caller OX0019CAEF) unresolved kernel trap cpu 0 Type 6=invalid opcode) registers
and on for many more lines which mean nothing to me, but I'll type them in if it will mean something to anyone.
Machine was new in March, and had additional 512mb ram pre-installed. No problems apart from failing to network with G4 and G3 running 9.2, until this download (which indicated it resolved some networking problems).
I've taken out both the original and additional ram, tried it with each on their own, with no difference.
It will restart from installation disk and I've re-set permissions and done a disk check which it errors before completing.
I've done a hardware check which is ok.
I've tried installing a clean system and it errors just before completion.
I've tried to use the Firmware Restoration which is supposed to restore the firmware after an interrupted or failed update - but the LED on my MacBook doesn't flash in the sequence indicated in the instructions and doesn't do the restoration.
It has been suggested by the dealer that I reformat the hard drive, but I have some photos that aren't backed up yet that I really don't want to lose. I've tried starting it in Target disk mode, in order to transfer them to another computer, but 3 other computers I've tried to link it to won't do anything.
I'd be grateful for any guidance!

Have you tried rebooting the machine in safe mode? Restart the machine, and as soon as you hear the chime, hold down the SHIFT key, until you see the grey screen. If it boots, you will see the login screen, and it will say (in red letters) SAFE MODE. This disables a good many of the features such as Airport, but also refrains from loading anything other than Apple kernel extensions. You can then log in, and either attempt to fix your problem, or at least offload your stuff that needs backed up so that you can try a reinstall.

MacBook Pro won't boot up after updating to Lion

I just updated my MacBook Pro to Lion. After install restart the computer is stuck on the white screen with the apple logo and spinning wheel. I manually restarted it after 1 hour but that didn't solve the issue. What do I do? Any advice would be greatly appriciated.

That sounds like the case. Good Luck.
check this link:
http://lmgtfy.com/?q=Lion+boot+disk
there is a ton of information, step by step. I am sure there is probably something here in these forumns on creating the boot disk.
Again I would start with a clean install of Lion off of the boot disk you create.
FYI I started with Snow Leopard time machine backups updated, then cloned my existing drive to a FW drive before installing. During the work day and in IT, It was a savior to target boot from the firewire drive to address employee needs when I was having Lion lock up issues from the initial install.
Wipe and install clean so far so good. No lock ups. And USB flash install was super fast. Then brought my apps over, or re-installed. This way everything was clean.

Mac Mini Won't Boot Up After HD Upgrade

So I have a Mac Mini 1.5GHz Intel Solo. I recently maxed it out with 2GB RAM and a 500GB Hard Drive. My problem is, when I start it up with the install disc all that appears is the folder icon with the question mark. Tried restarting holding down "C" and the same thing happens. I tried booting up with the install disc that came with my MacBook Pro with Leopard, and it gets me through to the main screen but then it tells me that this software cannot be installed on this computer. But I was able to format the Hard Drive. So I tried the Tiger install disc and the same folder question mark icon came up. Any ideas?

+"I have the install discs that came with my MacBook Pro, Leopard, tried those on the Intel Mac Mini and that's when it let's me choose a language but then a window saying the software _cannot be installed_ onto this computer pops up."+
+While _the same version of Leopard can run on Intel and PPC_, Tiger requires a different version for Intel than for PPC.+
The distinction is between installing vs. running.
Macs have generally not allowed install discs from one model to be used to install on an other model.
But an external Leopard bootable hard drive (with the correct partition map) can boot either Intel or PPC Macs capable of running Leopard. Of course the partition map has to be GUID for Intel, and APM for PPC -- and PPC Macs can only boot from firewire externals or from internals.

POWER MAC G5 WON'T BOOT UP AFTER GRAY SCREEN!!!!!!!

My wife was on my G5 one day and then came and told me it was messed up. When i turned my G5 on, the fans came on and it appeared that it was booting up. The computer got to the gray screen, had the little working icon under the apple logo came on, then it appeared to black out right around the the icon. The screen went black and then the screed said no connection.
Any help with this would be greatly appreciated.

Hi foleypopo, and a warm welcome to the forums!
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, 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. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then 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 perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
See if it will boot up to a screen by holding the Option/alt key down at bootup.
Any results?

Mac OSx won't boot up

After a minute of that loading circle under the apple symbol in the middle of the screen, the apple symbol turns into a no entry sign, which I've never seen before. I know there's a button to hold down when you switch the computer on that can take me to a different screen and I can run some repairs, but I forgot what it is, any enlightenment would be great

Hi Divus! and Welcome To Discussions!
Is this the No Entry Sign you are seeing?
What was the situation before this problem arose?
Did you make any changes to your system?
Exactly which model Mac do you have?
What OS are you running?
What size is your Hard Drive, and how much space is available?
How much RAM is installed, and is it original or added?

Mac Mini won't boot after failed XP installation

Recently upgrade HD to 320GB 7200 rpm and 3GB ram. Running 10.5.8 fine.
I tried to install Windows XP through Boot Camp, but wasn't successful, I terminated the installation. Then Mac Mini won't boot up. When powered on, you heard the chime, then grey screen showed and stayed. Tried starting with "C" (boot from CD), "OPT" (boot option), "T" (target), and reset PRAM. None of them worked.
What should I try next?
Thanks

If you install XP on Bootcamp, your startup disc will be changed to XP Windows partitioned you did. To restore your startup disc back to Mac OS, make sure your Mac is turned off. 1. Plug the power back and press the power button ON. When you hear the power On sound, press and hold the ALT key on your keyboard until you see the hardrives. 2. Select the HD that says MAc OS, then your mac will boot back to Mac OS.
Let me know if you have more problems, maybe I can 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.

Power Mac G5 won't boot with Lion?

After installing Lion, my early Intel 2010 Power Mac G5 won't boot. There were no problems for the first 2 days. The third day my G5 wouldn't boot at all. Not using Lion's recovery function, many attempts to boot from a previous system disk, and firewire target mode. The keyboard seems to be dead after attempting to boot except for the DVD eject key. All I get is a grey screen with an icon of a folder with a question mark within the folder. This icon blinks on and off continuously. Since the keyboard isn't working, I can't reset the PRAM, start in safe mode, or any other keyboard commands. The failed boot doesn't even get far enough for the Apple window to open. I replaced the hard drive and accomplished nothing except for spending even more money and time.
This is VERY frustrating! Has anyone else had a similar problem with booting after Lion't installation??
Thanks.

1) you have a Mac pro Early 2009, remember this. It avoids confusion here in forum
2) you're HDD's OS cannot be found by the firmware of the Mac hence it results to a question mark
perform the following(recommended to use a USB keyboard)
a) startup manager
press and hold option on startup. Do u see your HDD?
b) if you have a back up of your data then you can boot to the install disk and perform an erase and install
repairing the permission will not work since the disc's OS is different from the HDD's OS.

Mac mini won't boot anymore

My Mac mini won't boot anymore. It's been running fine for months.
It's running Leopard Server 10.5.2 Build 9C31
It starts to boot, I get the first spinning gear with the gray screen, then the blue desktop blinks, then a second spinning gear on a gray screen and it appears to hang (the gear stops spinning).
I booted off the install DVD, ran disk utility, repaired the HD, repaired the permissions: the behavior is the same.
Safe mode doesn't work (same hang as above).
Single user mode does work.
I can connect to it via Server Admin while it appears hung.
The last few lines of the system log are:

Yes, it's been running Server since I purchased it.
I doubt the serial number is in use elsewhere: I purchased the 10-user version at a retail store in a sealed package and I've only installed it once.

Mac Mini won't boot up.

Mac Mini won't boot up! Just getting blank white screen, any ideas why? No apple, just a blank screen. It worked fine last night.

Have you tried booting into the Recovery HD by pressing/holding COMMAND+R at system start or the Option/Alt key and choosing Recovery HD to boot into?
If you can get into the Recovery HD, open Disk Utilities and Verify Disk. Repair if necessary.
