Mac won't boot after power chord became unplugged accidently.

Mac won't boot after power chord became unplugged accidently.
I have a Mac Mini running very latest version of OSX. I was making a recording with QuickTime; when I needed to plug in a USB recording device into the back of the Mac Mini, as I pulled the Mac off my shelf to do this, the power cable came out and the Mac lost power.
I plugged it back in and powered up the Mac. I get the grey screen with Apple logo and the spinning grey wheel; then it goes to a blue screen (as usual) and I get the "starting OSX..." progress bar. When the progress bar finishes, I'm left with a blue screen only, no dock, no apple icon at top left, nothing across the top, no nothing.
So far, I've booted from the original disc and repaired the permissions as well as the disc, then re-booted, but same old blue screen.
I have another iMac G5 machine, so is there any way I can at least retrieve the important HD files from the Mac Mini to my G5, before throwing the broken Mac Mini away?
Can anyone advise please?

Hi, Nigel.
Not to differ with my colleagues here, but there's an important question that wasn't asked.
1. You wrote: "So far, I've booted from the original disc and repaired the permissions as well as the disc, then re-booted, but same old blue screen."Did Disk Utility report any errors it could not fix when you ran Repair Disk? I suggest you run the procedure specified in my "Resolving Disk, Permission, and Cache Corruption" FAQ. Perform the steps therein in the order specified.
2. You may also want to run the Apple Hardware Test that came with your Mini to be sure nothing shorted when the power cable was removed from the computer. I've seen it happen, hence I usually recommend removing the power cable at the wall before disconnecting the power cable from the computer. See my "Apple Hardware Test" FAQ.
3. Repair Disk gives your Mini a clean bill of health, the blue screen may be the result of some Startup or Login item that was corrupted due to the sudden power outage. My "Troubleshooting Startup and Login Items" FAQ can help you pin that down if such an item is causing the problem and may help you avoid and Archive and Install.
4. If you elect to go the Archive and Install route, see my "General advice on performing an Archive and Install" FAQ for some important tips on this process.
5. As FYI, this is the kind of problem that makes one glad they've implemented a comprehensive backup and recovery solution. For advice on the backup and recovery solution I employ, see my "Backup and Recovery" FAQ. Computing without a comprehensive backup and recovery solution is like driving without auto insurance.
Good luck!

Mac won't boot after updating to OSX 10.6.4

I am on my 3rd Mac that won't boot after updating to OSX 10.6.4. One MacBook Pro and two iMacs. I fixed one but the last two are getting the better of me. HD is not fried. Have tried every keyboard shortcut on startup, Disk Warrior via. Target Disk, repairing permissions in single user mode. The machines will not boot off of a CD or DVD and it will not boot up in safe mode. Something in the startup files is preventing startup. I am suspecting Sophos antivirus. I tried to uninstall it and trash it but I think it's still blocking something. Any help would be appreciated.

Got it! Not sure if removing Sophos had anything to do with it but here's what I did.
1) boot dead machine in Target Disk Mode (iMac)
2) boot good machine off Snow Leopard disk (MacBook)
3) install OS to dead machine- I found this next part very curious. When the install was complete the MacBook restarted as the iMac.
4) ran software updates
5) shut down MacBook then shut down iMac
6) rebooted iMac- all was good
I actually did this twice because a co-worker had the exact same problem on her MacBook Pro. Got both fixed today.
Thanks everyone for your help!

My MacBook Pro won't boot after a minor update. The update was all fine and my Mac acted like it used to but when I tried to boot my Mac it just loads the the update then goes back to the Apple logo and then shuts down.
I hope that someone has got a solution because I do not want to restore my Mac for the 4th time.....

thanks!

tigerswim, welcome to Apple Discussions.
Did you already have Tiger installed or did you have Panther 10.3 installed? Tiger is not a free upgrade; you have to buy it & then update (for free) using the download updates from Apple. Also, you have to use a universal/retail install DVD (or CDs) to install Tiger. You cannot use the install DVD from another model Mac.

Mac won't boot after I pressed the power button for it to sleep

Ok so, I decided to take a break and instead of turning off my PC, I put it on sleep by pressing the power button...and screen obviously goes black.
After an hour and a half I decided to return to my PC...and on pressing the power button it won't boot (nothing: no sound or sign of life).
Thought it may be due to the battery, however seems like it's fully charged as when I connect my adapter to it, the led light is green....
What am I going to do???? And I don't download or watch films or anything of the sort!!!!!!

1. Reset PRAM. http://support.apple.com/kb/PH4405
2. Reset SMC.     http://support.apple.com/kb/HT3964

IMac won't boot after power outage

I got a power outage a couple of hours ago. And now my iMac won't boot. When I power it up, it gets pass the white screen with the apple logo. The screen than turns blue with a spinning cursor. The cursor spins for about 10-15 minutes and stops but the normal login screen never appear and it won't boot into the desktop either. I just got a blue screen.
I have boot into the install Disc1 and did the disk repair and premission repair but it didn't help.
Any idea?

Oh man, what a disaster!
I tried to do an Archive and Install but the installation hanged at the end of disc 2 after running an iWeb script (according to the install log) with about one minute left. I have waited for two hours but it just hanged there with all the drives spin down.
To make the problem worse. There was no way to quit the install at that point because all the menu items were disabled. The only way out was to power off. But when I powered it back on, it booted right into install directly asking for the disc 2. If I put the disc in it will install again and hang at the same spot.
Disc 2 contains iLife. I know Apple wanted to make things simple but why can't they give me an option to skip it? After all, iLife was already installed.
I finally got it working by booting from disc 1 and did a clean install. It took me all night to re-download all the updates and reinstall many applications. Fortunately, I have my address book, calendar, and most of my works backed up to .Mac so it wasn't a total lost.
On the bright side. Now my iMac is working better than before. I used to have problem getting auto sleep to work but now it works perfectly. Safari also had problem accessing charts (but Camino was fine) in a few web sites like schwab.com. Now everything works.
Lenn and David. Thanks for all your helps.
Now I am looking for a better backup solution so that the recovery won't be this painful if disaster strikes again. Any suggestions?
Sidney

PowerMac won't boot after power failure during install

Hi, sorry if this has been asked. I searched, but I'm not quite sure how to phrase it.
I bought a used PowerMac from craigslist and went to install a newer version of OSX. I had a power failure in the middle of the install and now the computer won't boot up. How do I go back to a fresh re-install and get the computer to boot up?
Much appreciated!

Did you use a retail install DVD? If you used a gray disc from another model Mac, that could be a problem.
Because of the power failure, suggest you reset the PMU. How long was the power Off? You may need to replace the PRAM battery.

IMac won't boot after power failure during 10.5.6 update

Help!
Tried to update last night and at something like 80% install, we had a power cut. iMac won't boot at all now - get to a grey screen which tells me to restart. Don't have a wired keyboard. If I did - what are the steps to get this working again.
I believe I have a good backup, but don't want to risk as all the family photos are on the iMac.
Thanks in advance.

Thanks for the help, but can't even get to a screen where I could type anything! I know I'm being dumb here.

Mac won't boot after installing Kaspersky antivirus demo

when i turn on, the macbook pro has apple logo with spining grey thing but then it goes to just apple logo like normal and then it just stays like that instead of going into desktop?

I'm not sure that anything but a clone or Time Machine backup will work with Setup Assistant or Migration Assistant. Boot from the Recovery partition and use the Restore tab in Disk Utility. Drag your startup drive from the left pane (the indented icon that has your internal drive name) to the Source window. Drag the destination drive (the indented icon) to the Destination window. If you are copying to a drive with one partition this process will erase the destination drive. If you are copying to a partition on a drive with multiple partitions it will erase the partition you choose as the destination.
After the copying process is complete you can try booting from the cloned drive. Restart and press the option key after the startup chime. Keep the option key pressed until you see the Apple logo and spinning gear. Select the clone and click on Return to select it. If it boots run the Kaspersky uninstaller. Then download a copy of Carbon Copy Cloner (donationware) or SuperDuper! (free and paid versions). Use CCC or SuperDuper to copy the fixed clone back to your hard drive.
If the clone won't boot, and it probably won't, you will need to boot from the Recovery partition and choose to reinstall Lion. I haven't had to reinstall Lion or install it to an erased drive so if someone who has done so doesn't reply to this thread post a new question asking how to do it. It is my understanding that one is able to reinstall Lion over the existing installation or choose to erase the drive using Setup assistant to bring over your data from a clone. If you have to erase and install you will want to boot from the the Lion installation and clean off all the Kapersky stuff by searching for it (include invisible files in your search). Then you can use Migration assistant to bring your data back from your clone.
There is also a possibility that you can remove the Kapersky stuff by booting in single user mode. One you have your data copied to a bootable clone you could post a question about how to go about finding and removing the files in single user mode.

Won't boot after power loss

I've got the MSI Neo-FIS2R and have been living through all the various Bios issues with the rest of you.
One trick my motherboard has since day one, is when I pull the power plug. If I move the 'puter to another location, or just pull the power plug to open the case. When I put the power plug back in, the 'puter won't boot. I have to clear CMOS, and only then it'll boot. This has happened on every Bios from 1.1 to 1.5.
Any ideas?

Hi DVDGuy99,
I've not came across any like yours, but I'll suggest that you shut down your computer completely, wait for 1 min, switched off AC power from the wall socket, wait for 2~3 mins, then unplugged.
All the Best... :D!!!

MAC WON'T BOOT AFTER INSTALL OF MOUNTAIN LION

I recently installed Mountain Lion to my macbook late 2009 model. Now it won't boot, goes into this cycle of trying to start and then off.

Try holding the Shift key when booting, to see if the system will start up in "Safe Mode" (by only loading essential services and extensions).

Mac mini won't boot after power outage

I have a Mac Mini Server which runs all the time in my house. We had a power outage a couple fo days ago but I didn't happen to check the mac mini until today. I found it at the login screen, and proceeded to log in. Everything was slow and taking way too long. Finally it froze. I restarted, but this time I got to a grey screen with a progress bar (no progress shown).
At this point one of two things happens - either it switches to a spinning wheel forever, or it just shuts itself off. I've restarted many times and it seems to randomly choose one of those outcomes. I tried resetting the SMC by unplugging, waiting, and then plugging it back in, but this had no effect. I want to reset the PRAM, but it doesn't seem to work, although that might be because my keyboard is not an Apple keyboard. I'm trying to get another ekyboard to try, but besides resetting the PRAM, does anyone have any suggestions?
Thanks.

Try booting to the OSX disk that came with the Mini
and run disk utility and try Repair Disk on the boot drive.
Also, if you have a bootable clone, try that.
If you have another Mac, another thing to try is
getting the Mini to start in Target Disk mode and connect
via Firewire to the other Mac and try a repair disk that way.

Mac won't boot after prohibited symbol

I'd like to thank in advance anyone that will bother reading this. My guess is there is something wrong with the logic board...
I believe my macbook is the early 2011 13" model. kitted with the i7.
Here is a sequence of maybe relevant, maybe not, events that happened before the issue:
1- I run bootcamp quite often
2- I had been running my macbook on clamshell mode for about 2 weeks, connected to an external screen and keyboard&mouse
3- I installed a large amount of plugins for pro tools (10-15Gb worth) the day of the incident.
4- The last time i shut down the computer, i changed the boot disk to mac OSX, under the bootcamp menu in Windows' control panel.
5- When I booted up the next day the boot was going fine until the prohibited symbol appeared, replacing the apple logo.
5.1- After some time, the screen went light-blue (the snow leopard color thing) and the computer suspended itself. (it usually does that when i run it in clamshell mode, right after it finished booting, presumably because the lid is closed)
5.2- The computer was unresponsive to mouse and keyboard input, so i unplugged it and opened the lid.
5.3- It went to desktop, but rather than a mouse, i had a static colored wheel (which i could move). The dock didn't come up, and everything was frozen.
6- I long-pressed the power button to shut it down.
7- When turning it back on, all i can hear is that growly sound from the optical drive/hard drive (not really sure tbh), and the screen doesn't turn on. I can also hear the fans running, and the CPU area heats up.
On a sidenote, i don't hear the traditional apple chime ever since i had HDD data corruption problems and had to run system recovery into a more recent OS. After which i reinstalled a snow leopard (10.6.8) via a system backup i had, which dated from 2011 (and that was this year).
So, is there a magical key combination that will resuscitate my mac? Does this look like a 500€ fix on the logic board?
Thanks for reading!

Also, i don't hear any hard drive read/write activity, so i'm not quite sure if it's spinning.

IMac won't boot after power failure?

My iMac wont boot or respond in any way after I experienced a brief power outage. Now it can't seem to switch on at all even after attempting the different resets I've read on other discussions. Please help with advice on any techniques to fix it otherwise steps I must take to get it repaired. Thanks.

Mac Won't Boot after Boot Camp Windows Update - Macbook Pro Mid 2010

Hello All, and thanks in advance for any assistance you can provide.
I have a Mid 2010 Macbook Pro. Last year I upgraded the RAM, then this year I decided to upgrade the hard drive to an SSD-hybrid. Everything went perfectly smoothly with both upgrades, and I was a happy camper.
I had also installed Boot Camp with Windows 7 and everything worked perfectly. Then last night, I boot in to Windows 7 and it gives me a 'service pack update'. After installing it, I had to reboot my computer. Rebooted it and it accidently started booting OSX. No problem, I thought. I held down the power button, and booted back in to Windows. The service pack installation continued and it had me restart my computer an obscene amount of times during the installation. This is when I initially thought "this is weird".
Finally the service pack installs, and I'm able to use Windows 7 again. Then I shut down the machine and tried to boot back into OSX. No dice.
Here's how the OSX booting process goes:
First, the Apple logo appears, then what appears to be a progressive loading bar at the bottom. After a few seconds, the loading bar disappears. Then it's just at the Apple booting screen with the spinning wheel/gear and sits there indefinitiely. I let it sit there for over an hour last night and nothing happened.
Any suggestions? I tried resetting the NVRAM and the SMC.
Thanks so much,
dlevv

It looks like a hard disk problem. Press Command and R keys on boot, open Disk Utility, select Macintosh HD in the sidebar and repair your drive
