IMac 2008 won't move past apple logo after kernal panics

HELP! My iMac has become quite the problem child. It's early 2008, and in 2011 the hard drive crashed...now I'm getting a stream of kernal panics. I thought it was insufficient memory so after I finally got it to boot up after a kernal panic - I cleared out a bunch of videos and freed up like 75% of my 500GB drive. SO I thought I was in the clear...then the screen saver came on and apparently that triggered something and it locked up. Did a reboot and got another panic. I've tried command + R to go into recovery mode and it won't get that far - not even sure if command + R will work on the early 2008. I am running Lion, not sure exactly what version since it won't power up.
My husband is ready to be done with apple altogether but I'm not ready to part yet. Anyone have any ideas?

OH and I tried to run the Apple Protection CD and it just spits it out. The only thing I have plugged in is the power cord and the keyboard.

IPhone won't reboot past Apple logo.

iPhone 4 won't reboot past Apple logo. It will not show up in iTunes to perform a restore. I can't even get it to turn off. Help?

Reset phone - press both home and sleep/wake buttons until the Apple logo reappears.
If that doesn't work, try recovery:
1. Update to latest iTunes (10.3.1)
2. Connect phone to a USB port directly on the computer
3. Press both home and sleep/wake buttons until the Apple logo appears, then continue pressing the home button alone until iTunes detects the phone in Recovery mode.
4. Follow the prompts to restore.

IPhone 5 won't reboot past Apple logo. It will not show up in iTunes to perform a restore.

iPhone 5 won't reboot past Apple logo. It will not show up in iTunes to perform a restore.After the logo appears the phone will get switched of by its own. I updated my phone 2 days before.

The iPhone can only be serviced in the country where it has been bought, and it can't be shipped internationally to Apple Support, you'll or somebody else have to bring it personally. If you registered the phone with your Apple ID, you might not need the receipt, Apple Support should have your data.
Did you try to set it back to factory settings without using any backup afterwards?

Won't start past apple logo, won't boot from install disc

mbp penryn 2.4 core 2 duo won't boot past apple logo. Running mtn lion 10.8... inserted Snow Leopard install disc, held down C key, only get a grey screen.Recently installed new HD, (seagate 750 Hybrid), upped ram from 2x2 to 2x4. All has been running very smoothly (and much cooler) for the past 3 weeks. Then this, prompted apparently by the mac going to sleep w/o being plugged in. Ran battery down, I suppose? Happens frequently.
Any suggestions?

ds,
"You might have ruined the RAM by handling it and touching the contacts.
Once you put new good RAM into the machine, reset SMC and PRAM then boot it up."
On the odd chance that I did ruin my ram I replaced w/ 4gb brand new ram, reset SMC and PRAM, then attempted to boot. Still a grey screen. Also re-attempted to put mbp into target mode, but no luck there either, nor with ejecting the Snow Leopard install disc via option/trackpad method, both on startup and while running, and no luck there either. I have a second Penryn mbp that I could salvage for a spare part if I knew what the problem might be. So far I get the idea from your responses that my machine SHOULD be rebooting, but for some reason isn't.
If this helps:
I hear, consistently on attempting startup, fans powering up, then two short whirrs as if a drive head is moving, then when the fans quiet down after 30-45 seconds, another short but different whirr, then only quiet fans and a grey screen.
Thanks in advance for any reply.

IPod Nano Won't Boot Past Apple Logo...

Sup all?
...Got an interesting problem here. Replaced an LCD in a Nano for a friend, installation went smooth & without problems (or so I thought). After installation was complete, I put the Nano back together & started loadin' & playin music on the Nano. About 2 days later, I decided to update it w/the new iPod Updater (can't remember the date). Now the iPod Nano won't boot past the Apple Logo. I can tell that the "menu" has been loaded 'cuz you can hear the clickin' sound when you operate the wheel.
I've tried reformatting the iPod Nano (quick & full) & then trying to restore it, but it won't boot past the logo (after successful restoration?). Now I'm going to run the battery dead & then try to restore it again.
Any suggestions/comments on this?

The solution I see in your case is to go back and download an older iPod Updater.
See this link -> iPod Updaters
I suggest taking either the January 2006 iPod Updater, or March 2006 iPod Updater.
IMHO, Some of these freezing issues occur because of a fault in the latest iPod Updater.
I suggest going back to March (or January), and the nano could possibly work again for you.

IMac won't go past apple logo screen and vertical lines on display

I have an old white iMac that won't boot. When booting up the screen has vertical purple lines and I can see the Apple logo. The little "dial" just spins and spins. Does anyone know how to fix this? thank you for any and all help.

The vertical lines are indicative of a hardware problem. It is possible (likely) that this is also related to the inability to start up as well. It's almost impossible to diagnose and explain repairing hardware in these forums, so I think it best if you take the computer to a repair shop that is familiar with Macintoshes.

Mac Mini won't boot past Apple logo and spinning wheel

Hello,
I have a Mac mini (late 2009) running 10.8.2. Today, I tried to log into the computer. It accepted my username and password, but then the screen turned gray instead of logging in. I left it like that for about twenty minutes, then gave up on waiting and Ctrl-Command-Power rebooted it. It then wouldn't reboot: it gets to the Apple logo and spinning loading wheel, but won't go past there.
So I went into single-user mode and was able to access the HD fine. I ran a filesystems check using the recommended syntax (/sbin/fsck -fy, I think). It said that the volume looked okay, and that it had been modified. I took this as a good sign (that it had been repaired) and typed "reboot" to restart the machine. I held Command-Shift-V to perform a Verbose Safe Boot.
The computer makes no further progress after the following four lines:
vboxdrv: fAsync=0 offMin0x809 offMax=0x2bc3
VBoxDrv: version 3.2.12 r68302; IOCtl version 0x140001; IDC version 0x10000; dev major=34
VBoxFltDrv: version 3.2.12 r68302
VBoxAdpDrv: version 3.2.12 r68302
I'm assuming all the instances of "vbox" are in reference to Oracle's VirtualBox VM. I do have VirtualBox installed, but haven't used it in a while (months), so I don't see why it's suddenly causing a problem.
To clarify, the computer doesn't "hang" after these lines: I can still type text into the terminal. The entire log is being saved to /dev/console, so I could probably grab it from Single-User Mode if necessary.
Everything else seems to be working properly: even the wl0 drivers are loaded.
Does anyone have any suggestions about how to fix this, or at least disable VirtualBox so the computer can start?
Thanks!

Cult of Mac post:
When the Apple Logo appears your Mac has found a valid system disk, and Mac OS X begins loading.
Apple Logo with Spinning Gear
Once the spinning gear appears the BSD kernel (Darwin) has assumed command and begins loading device drivers. Shortly thereafter it transfers command to the almighty (and controversial) launchd process. Such are the workings of UNIX.
What this means for us mortals is that when a Mac stalls at the Apple logo or the logo with a spinning gear, it probably has a corrupt Mac OS X installation. It may also be having trouble accessing an internal or external hardware component, but this is less-likely.
Rebooting your Mac in Safe Mode can sometimes get things working well-enough that a second, normal reboot then works normally Hold down the Shift key at startup to boot in Safe Mode. DiskWarrior is also worth a shot (this is by far my most used disk utility). If that doesn’t work, an Archive & Install may be needed.

How to show us a screen image. Avoid personal identification.
command + shift + 3 Will take entire screen. You hear a click.
command + shift + 4 Lets you decide what to take. Mouse pointer changes. Move mouse to upper left corner of desire image. Hold down left mouse key where to start image. Drag mouse to lower left of where you want to stop image. Release mouse.
You will get a picture n.png file on the desktop.
On the forum input panel you will see the camera icon.
click on camera icon.
another window will appear.
Make sure you have selected the from your computer tab.
click on Browse button
An open file panel appears. Select the file.
After selection a file, I have this screen showing.
You will have to click on Insert Image. You may have to scroll down to see Insert Image button.

Iphone 3G won't boot past apple logo - not typical case that I've searched and read about

I am attempting to fix an Iphone 3G for a friend. Before the phone stopped working, they said the battery life was getting worse progressively until the point that they had to turn down the brightness and have it plugged in often. The phone was jailbroken and unlocked for use on Tmobile. I don't know what firmware it's on nor how it was jailbroken, just that they said it worked fine for 3 years. When this problem first occurred, my friend was able to get the phone into recover mode, but it would shut down after several seconds even when plugged into a computer or power source.
Currently, the phone will not boot past the apple logo. It powers up, goes to the apple logo, and powers down 20 or so seconds later. The spinning gear never appears. I can not get the phone to boot into recovery nor DFU mode. The computer doesn't recognize it or even acknowledge when it is plugged in, so irecover that some people use to solve their recovery loop mode i won't work either. I have the luxury of having a functional iphone 3g that I used to swap parts to narrow down the culprit.
Steps taken:
replaced battery
swapped usb connector on bottom of phone
swapped lcd assembly in case it was the home button
took the motherboard out and placed it in the working phone, and it still doesn't boot past the apple logo
I'm out of ideas at this point. Thanks for anything you guys (and gals) can think of.

I See a lot of those on my bench. The cause is the charge IC is burned out usually by a non Apple cable. The only way to get it to fully boot is to put a fresh charged battery in. Once a new fully charged battery is in it will continue to work fine including charging. But if you ever power off the device or it turns off due to dead battery it will not boot up on its own And you will need to swap batteries again.

It is hard to give accurate help without knowing exactlly which iMac you have or what OS X it is on.
At this point I can only suggest, starting up from either the OS X or Tiger copies that you have and see if you can Repair your (Macintosh HD) Startup Disk.
If the copies of OS X or Tiger are good, then you should be able to startup from one of them holding the C or Option key, navigate to Disk Utility and Repair your Startup Disk.
Start from your Mac OS X Install disc: Insert the installation disc, then restart the computer while holding the C or Option key.
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.)
Click the First Aid tab.
Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
Select your Mac OS X volume.
Click Repair. Disk Utility checks and repairs the disk.
If you can not startup from any of the discs that you have (OS X Tiger or Disk Warrior) to make repairs, then your only choices are to seek help from either your friend or an Authorized Apple Service Provider.

Tried almost everything, iMac (2008) still stuck at startup (Apple logo)

My iMac from 2008, currently running 10.6 but was originally a 10.5, has been stuck on the white screen + Apple logo with no spinning beach ball.
There were no troubles before this, I just turned it on one morning to it like this.
I've practically tried everything to no avail...
Safe boot: goes back to Apple logo
Option key: the HD is shown, but goes back to Apple screen when clicked
NVRAM/PRAM reset: did nothing but make the volume and screen brightness back to default
Verbose mode: gets stuck on "Executing fsck_hfs..." and doesn't proceed whatsoever, even after hours of it being on
Single User mode: same as Verbose mode. Just stuck, never proceeding.
Sometimes it goes on a restart loop until I stop it with a NVRAM/PRAM reset.
Sometimes it beeps 2 times, then goes on to 3 beeps until turned off (RAM problems?) but not all the time.
I'm thinking I should just do a complete and clean reinstall of the OS to see if it'll help...but my optical drive hasn't been working for a while now, so I can't just stick in the CD...
Is it worth it to go and buy an external CD/DVD reader and try to do a clean reinstall from that? Is that even possible?
Have an idea on what might be causing this? RAM? Corrupted files??
Should I suck it up and go to the Apple store? (Which I'm trying to avoid, as an iMac is heavy and I have no car)
Any help will be grately appreciated!
Thanks for reading.

I fixed it!
I thought I would post what I did in case anyone else in the future has the same problems as me.
I went out and got an external CD/DVD drive and plugged it in with the first install disc that came with my Mac. (The grey CDs with 10.5, not the 10.6 upgrade DVD)
Pressing C on startup didn't work, so I pressed D instead and got the Apple Hardware Test. After testing, I got a 4MEM error, which means it was the RAM.
Tested one RAM at a time, and it seems like one of them had stopped working. I also tested the good RAM in both slots in case it was the slots that were erroring, and not the sticks.
Then, I booted up my Mac again with the good stick of RAM, pressed C, and went into Disk Utility. There, I verified and repaired the disk (there were some errors there too, but it fixed it up).
I rebooting the Mac with one stick of RAM, and it started with no problem!
But because I'm only running on 1GB, things are a bit sluggish, so I'm going to use this opportunity to upgrade my RAM. All is right in the world again.

IPad in a boot loop, won't get past Apple logo

Hi
My iPad 2 is stuck in a boot loop, doesn't get past the Apple logo. I've held the sleep/home button together many times and it hasn't worked. Tried to do a restore in DFU mode, goes all the way the end and starts rebooting again. Even tried re installing the firmware on it and it goes all the way to the end then starts rebooting again. Tried hitting it on the back and this didn't work. There has been no damage to the iPad.
Any other suggestions please?
Many thanks
Dominic

Thanks for the replies! Anyway, I gave DiskWarrior a try and it failed to work. The first time I tried it, I put the disc into the drive of my MacBook Pro and booted it from the disc. After going through the rebuild process it told me that due to a hard drive malfunction it couldn't append any changes to the drive. I then tried putting the disk into my iMac and used my MacBook Pro in Target Disk mode. This wouldn't even attempt to rebuild my drive saying that there was a hardware failure.
So, I booted into Windows 7 and saw that Windows was able to access the drive and read the files perfectly. All the files were in tact. I don't understand why disk warrior had a problem with it. Anyway, what I can do is reinstall Mac OS X Snow Leopard onto the hard drive again after moving the data onto an external hard drive using Windows. The only problem is that I would have to reinstall all of my programs while reimporting all of the settings and data that I can from the external hard drive. What I want to know is can I make an image of my hard drive (with SuperDuper?), and append that back onto my Mac's hard drive? Would that work again after reformatting the disk or would it just give me the same problems as before? Would it be better or easier to just start new and reinstall everything? Thanks!

IPod Video Won't Boot Past Apple Logo

I've had my 5th Generation iPod Video (80 GB) for about 1 1/2 years. I was using it the other day and it froze in the middle of a song, so I used the reset function to reboot it. Now it won't boot past the Apple logo; it just stays there (until the battery runs out).
I definitely can't use the iTunes "restore" function, since I've been unable to get my computer to acknowledge when it is plugged in.
I'm guessing this means my hard drive is done for? If so, I'm comfortable replacing it myself, but I could use some advice regarding a good (and economically priced) replacement drive. After a quick look inside my iPod, it appears the hard drive model is a Toshiba MK8010GAH.

You might try forcing the iPod into disk mode first, then connecting it to your computer and see if that makes it show up in iTunes...

MacBook Pro won't get past Apple logo during boot

Hey, recently while I was using on my MacBook Pro (note: just simply browsing the internet), the battery ran dry and the computer shut down almost immediately. When I plugged it in and turned on the computer again, the familiar Apple logo appeared and looked as though it would start up normally. However, an unfamiliar grey progress bar appeared and the usual grey gear started spinning. The progress bar looks as though it reaches up 10-15% completed but the computer just shuts down after that every time. I know it has nothing to do with the charge in the battery as I tried doing it plugged in and even waiting overnight for the battery to charge fully with the plug plugged in.
So, I tried using Disk Utility on the Snow Leopard Install disc (my original MacBook Pro install discs had Leopard on it so I just used the Snow Leopard discs instead). After using the "Verify Disk" command on the Macintosh HD volume, it stated that 'Invalid node structure' and then stated that the disk could not be verified and needed repair. I then proceeded with using 'Repair Disk' and it did say 'Volume repair complete' but then stated 'Updating boot support partitions for the volume as required.' This was when an error popped up and said "Error: Disk Utility can't repair this disk" and then told me to back up my files and reformat the disk.
I'm hoping that I don't have to reformat the disk as I haven't backed up in a while. I do have a separate partition on the hard drive that has Windows 7 on it that I can boot to. At least that means my hard drive hasn't completely died on me. However, I'm unsure what to do at this point to fix the computer. I tried to Safe Boot but it didn't change the outcome of start up.
Any ideas as to what I can do? I appreciate any help.

IPad 2 won't get past apple logo and various other problems...

I knew I shouldn't have updated to iOS 8, my iPad was getting increasingly slower with each software update since I bought it a few years ago.
A few weeks ago the first problem arose - the home button suddenly became unresponsive. Initially it would work on about 1 in 10 clicks, but then nothing at all. I managed to get to settings to turn on accessibility features and the gestures to replace the home button so that wasn't much of problem, just annoying. I tried various things online that people claimed fixed this issue but nothing happened.
Then about a week ago it suddenly wouldn't wake up in the morning. I tried turning it on and it would get to the apple logo and stay there for a couple of minutes then go black again. I plugged it into iTunes and restored it etc hoping something would happen but of course nothing did.
And I obviously can't reset it on the device itself due to the home button being completely dead.
I left it for a few days then today I came back to it and tried to plug it into iTunes again and now iTunes won't recognise that it's plugged into my macbook at all.
Basically does anyone have any advice or should I just accept that it's dead at this stage and give up? Let me down gently!

Hi there SraZamora,
