IMac :: Can't Boot From Cd?

Feb 24, 2010

I found this beautiful 17" eMac at a yard sale! it is pristine I fell in love. I went about removing the stuff left behind by the old owner. Now it does not boot.

After a while I get the question mark on a folder. I know what I did but not how to get out of it. I have no OS X disk to start it from. What do I do now? I did try to reset some things but no good.


IMac :: 27" Wont's Boot Up / Takes A Very Long Time To Boot?

May 15, 2010

I have a 2 week old iMac 27", i7, 2tb Hard Drive, 16gb RM

In the second week the boot up times became very slow.

I would turn the machine on and get the chime within 5 seconds or so.

Then just a black/blank screen.

Eventually after about 10mins I would get a white screen then it would boot up normally.

Now the machine just doesn't get to the white screen. So I get the chime and then just darkness. It does sound like the machine is on (usual quiet imac whirring).

I've tried various key commands when I turn the machine on including pressing C with the install disk in the dvd drive and the alt, control, P, R pram reset.

I've also tried unplugging all the cables, leaving the machine for a minute and switching back on. I did manage to perform the PRAM reset once. I reset the machine and it booted fine.

But now when I switch it on just darkness.

I've called after sales and will try to get the machine replaced but in the meantime is there anything I could try that might make the machine work? I need to do a remix this weekend (deadline Monday) so really need to get it working.

IMac PPC :: Imac G3 Installation Of Tiger Cd Won't Boot?

May 14, 2012

I have the CD version of tiger and am trying to install it to a recently purchased iMac G3. The Installer installs disc 1, resets, but doesn't boot up to install disc 2, it simply asks again to install disc 1. The Mac for some reason will not boot from the installed software and therefore I cannot complete installation. Can anyone figure out why the mac refuses to boot from the HD in order to install disc 2?

IMac :: Won't Boot Up - Possible To Identify What's Wrong

Mar 29, 2009

I usually leave my iMac turned on with just the monitor switched off. That was also the case when I left yesterday for a day trip. Coming back today, I noticed that it was shutdown. Pressing the power button, I can hear the familiar "ding" of boot up, the fans running, the usual dvd drive sound and after that it just shuts down. Not even the monitor will power on. Before I start panicking since various thoughts are crossing my mind, is there anything that I can try to possible identify what's wrong?

OS X :: Imac Won't Boot Up After Downloading 10.4.1

Nov 18, 2009

I have a 15" Imac G4 I bought used off of Ebay. It was doing great and then I clicked to look for updates. So it downloaded a 168mb file to update 10.4 to 10.4.1 It automatically tried installing, but then said it couldn't install and that it was moved into the trash. So I took it out of the trash and dragged it on my desktop. Then when I went to turn the computer on, it only shows the grey screen!

OS X :: Imac 24" Won't Boot Up

Jul 22, 2009

I have a 24" imac with the dualcore. Yesterday I was pasting something from Illustrator to photoshop and it froze. The ball spun for about 5 mins, force quit would not come up so I held the power button and shut it off. Now only the grey screen comes up like its booting, apple logo and spinning wheel. I started in safe mode and ran fsck but it seemed to take forever (hours) and never finished.

OS X :: Safari Kept Hanging - IMac Won't Boot Up

Nov 21, 2010

My wife's iMac MC508 is 2 weeks old, I had to re-install it after 1 week because Safari kept hanging. It was working ok yesterday lunchtime when I used it but last night my wife switched it on and just got the white screen with logo, then a blank progress bar then the circle thing before it shut itself down. We have tried all the key combinations that we found online but no change. The only thing I have not done is put the install disk back in for fear of not being able to eject it. Has the hard drive packed up? Does this mean a trip to an Apple store?

IMac :: Won't Boot - Hdd Failure?

Dec 11, 2008

The string of problems I've encountered started a few days ago. I normally let my imac go to sleep by itself but, on this occasion I told it to sleep via the apple menu. When I awoke the imac the screen was frozen. No mouse movement, no clock movement, nothing. At this point I turned the power off and back on again. It didn't get past the white screen (before the gray with apple logo). I then tried resetting the PRAM, booting in safe mode, and booting from my os disc. Nothing worked.

After several tens of tries it magically booted. It stayed active long enough for me to back up all my data (transferring at least 100GB), reformat the hdd, reinstall leapord, transfer data back, and use it until I let it sleep again.

OS X :: IMac Won't Boot With 4GB But Will With 3GB?

Apr 7, 2009

When I look at "About This Mac" it says that I have a 2.4 GHz Intel Core 2 Duo. I originally had two 1GB sticks. When I installed two 2GB RAM sticks, it wouldn't boot. Just for fun, I tried putting one 2GB and one 1GB stick inside, and it boots fine.

[URL] says that I can have up to 4GB: [URL]

But the guides say that it depends on if I have Merom w/ Santa Rosa chipset or not:[URL]

But I read somewhere else that even if I install two 2GB sticks that it will just ignore the power of the second one and default to 3GB.

OS X :: Intel Imac Won't Boot Up And Is Freezes When It Does?

Jan 7, 2010

I was working with logic pro 8 on a project when the APP crashed. Then, the whole computer became real slow. I couldn't open anything without getting the spiraling rainbow circle for at least 3+min and even then the app wouldn't launch. So I shut down normally, which took a while.

After I left it off for about a min or so, I tried to boot again just to get stuck on the gray screen with the apple logo. I did some research on my phone (since I currently don't have internet because I'm moving this week) and found out how to reset the pram. I tried it, and this time it got all the way to the blue screen where it got stuck. I tried resetting the pram a second time to finally get to the log in screen but everything was going very very slow. Unusable type of slow. Opening a new finder window took at least 2 mins and everytime I ran my mouse across the idock, it would freeze.

Software :: IMac Won't Boot Completely

Jun 23, 2008

Attempting to fix neighbor's iMac. (OS 10.4.11) Won't boot completely. I'm running DiskWarrior as I type. It's been running over an hour so far, and I'm up to 123 overlapped files on step 6 (out of 12)

1) What are they, how do they happen, and how to prevent?
2) Happened once before on son's computer and only way to fix was to archive & install. Don't know if DW can fix it this time or not--won't until DW finishes.

(Have updated # of files several times since I started typing!!!)

IMac PPC :: G5 Won't Boot Properly?

Apr 18, 2012

Recently I inherited an iMac G5 (no iSight) that has bluetooth and a preinstaled airport card. When I recieved it the drive was wiped so I did an install from the original disks. My problem is that the computer will not boot properly ; I can hear the chime, mostly the lcd lights up but it stays black, sometimes I will see the gray screen and from there it will either go to the light blue screen and hang or it will distort the picture and the fan will kick in. 2 out of 20 times it will boot successfuly but after about 1 min. it will freeze up, distort the image and then the display goes crazy! I don't know whats wrong... the capacitors have been replaced a not too long ago along with the power supply, and I ran a hardware test and it says everything is fine ( the G5 won't recognize the airport card or bluethooth!). I need help!

IMac PPC :: G5 Loud Clicking And Can't Boot?

Jun 23, 2012

Compter was frozen on the desktop screen making clicking noises (hard drive?), had to unplug to restart. Now won't boot past grey screen with flashing question mark and still makes clicking noises occasionally. Holding option key doesn't let me select volume to boot from... inserting startup disk for Leopard doesn't work, have reset PRAM, NVRAM, and Open Firmware and have tried to access single user mode without any luck... what are my options? I am more concerned with recovering my data from my hard drive than saving my aging computer.

IMac :: Won't Boot Past Apple Screen

Mar 5, 2010

I have one of the old blue PowerMac G3 computers, and I kept getting a kernel panic, so I reset the RAM and now when I start up the computer, it stops at the apple screen without even spinning. I've tried booting it in single user mode, and for some reason it doesn't make a difference what keys I hit while turning on the computer. It still boots to the apple screen.

OS X :: IMac 24" Kernel Error With New HDD And Can't Boot CD

Mar 18, 2010

Recently my iMac 24" was randomly shutting off, finder unresponsive, applications could not launch, and startup would take upwards of 4 minutes. Thought it was most definitely a harddrive issue because when I would option-boot (had windows 7 on another partition) no bootable drives would appear and upon trying to boot the install CD I would get a Kernel Error. I ended up getting a brand new 1.5 TB this afternoon and installed it in the iMac a few hours ago. Now when booting the computer I get the HDD with a question mark as I should since there is not data on the drive... Problem begins when I try and boot from CD, where I'm getting a Kernel error. Spinning circle for about 3-4 minutes after selecting CD from the option-boot or when booting while holding down C. Here are the logs from my Verbose mode boot, I have nowhere for the logs to save so i had to take hi-res pics, sorry.


System Specs are as follows. Aluminum 24" iMac running OS X and Windows 7 (both with all updates) 2 gigs of ram geforce 8800 i think.... Memory should be fine, i have two 1 gig sticks, and I've tried booting the computer with each of them installed separately. Also have tried resetting nvram, pram, etc... ALL the usual recommended steps so you can skip those suggestions.

OS X :: IMac Won't Boot After Recent SL Graphics Update

Aug 18, 2010

Im having my first ever problem with a Mac, bummer! I have tried Googling an answer, but didn't find anything specific enough for my situation.Last night I installed the SL Graphics Update, hoping to be able to run Starcraft 2 on a higher setting.

Anyways, I installed it, and now the computer wont boot. It is stuck on the gray screen with the spinning symbol. It appears to be installing the software update, since it shows a gray progress bar, but then once that finishes, it just stays on the gray screen with the spinning symbol and goes nowhere after that.

I have a Macbook Pro available to use, if I need to target the disk. Not sure how to do that though, just found that idea in my google search.

I have no problem just being able to grab my important data off of it, and starting on a fresh install. I just dont want to lose my huge library of pictures and music.

Software :: 24" White Imac Won't Boot Up?

Jan 22, 2009

white 24" iMac purchased in the fall of 2006 2Gb RAM 500Gb HD

First sign of trouble:

While watching trailers at I noticed some pixels on the screen were pink and blue. Not in lines but just in random spots. They would disappear now and then when you moused over them.

Tried some restarts and eventually it would sometimes freeze at the blue screen with the mouse usable.

I did a safe-boot and everything was fine and normal. No pixels, almost seemed normal. After a few more restarts and resetting Pram, Safe mode began showing pixels as well.

I was getting concerned for the data on it at this point and hooked up a firewire cable and booted it up in transfer mode and got all my data off.

Now I wanted to try and to a clean install of Leopard 10.5.

Second sign of trouble:

Now the computer won't get past the grey screen with the apple and progress wheel. It will be just about to go to the blue screens when the wheel will freeze and thats it.

Should mention the grey screen is now covered in pink and blue pixels everywhere.

Safe-boot won't get in.. Resetting Pram doesn't change anything.

Command Option O F doesn't work.

Tried booting from the install disc, holding 'c' down it almost works then the message of "You must restart your computer" in like 10 different languages comes up.

Holding down option lets me choose b/w the hard drive and OS install disc but still gets the restart message.

I am pretty much resigned to "looks at watch" submit the official time of death on it. Ever since the original iMac in 97 this is the first Mac that has ever died on me.. Kinda shocked and disappointed.

Any confirmations or suggestions on how or why it died would be helpful. Was it a hardware or software breakdown. My guess is hardware. /shrug

Or just maybe there is a fix still out there

PowerPC :: 15" IMac G3 Won't Boot After Upgrade Hardware

Jul 13, 2009

Just bought a fantastic condition deep-blue 500 MHz G3 DV iMac yesterday for 15. Steal! The original hard drive was knackered so I've replaced it with an 80gb 5400RPM one which should be more than adequate. I'm aiming to get OS X on it. My 350 MHz G3 runs is well, so this should scream. Unfortunately, OS9.0 and OS9.1 disks in the optical drive still produce a flashing folder icon. I need to boot OS9.0 in order to flash the iMac's firmware before I can stick OS X on it, but it just won't boot at all. I'm thinking it could possibly be a knackered optical drive, but before I go to the trouble of finding a workaround, I wondered if anybody here might have some ideas.

IMac :: Won't Boot Up - Unreadable Cd Stuck In Drive And Eject

Jul 16, 2009

My Intel based imac (purchased in Sept 07) won't boot up because there's an unreadable movie dvd in the disc drive that won't eject... when I turn on the computer, all that happens is it plays the opening chime and displays a white screen... I'm wondering if someone can help or suggest what's going on: Basically I put a movie dvd in my imac that my regualar dvd player wouldn't play so I thought I'd try it in my imac. Once inserted, the disc drive tried to read it but it wouldn't mount, it just made an odd spinning/grinding sound. It wouldn't eject using the keyboard eject button so I shut down my computer so that I could call a friend to ask for advice.

My friend gave me several options to try - holding the left mouse button at start up, hold C down on keyboard, command option O F to open firmware, reboot pram but non of them work. Basically when I start my imac it immediately tries to read the unreadable dvd and doesn't get to the normal start up procedure, it just shows a white screen and chokes on the dvd. Is there a way to manually eject the cd or does the machine have to be opened up and the cd physically removed? Is it likely that my imac will start up normally once the unreadable dvd is removed? I hope my hard drive hasn't gone bad because I haven't backed it up in a long time... Is there a strong possibility that my hard drive is toast?

IMac :: Unable To Fix Boot Camp / Can't Install Windows

May 1, 2010

I own every piece of software and hardware from Apple there is and I cannot understand that it seems that everything is about the iPad and iPhone right now. I have been having these issues since I got my 27" iMac. I can install Windows 7 just fine on my MacBook Pro and my previous 24" iMac.

Ever since I got the 27" iMac I get a black screen when installing Windows. I have found some posts that have a way around it, which seemed to have worked but now I am getting the blue screen of death. Doesn't matter if Windows 7 is supported by Apple or not but Boot Camp is and it should be corrected.

There is no excuse that after 6 months this issue has still to be addressed, all Apple talks about now is iPad and iPhone, I am sick of it.
BTW I own an iPad and I don't see the big fuss about it, I bought it mainly to read books and watch Netflix on the go.
