OS X V10.7 Lion :: IMac Starts To Boot And Then Shuts Off?
Feb 4, 2012I have a 2009 iMac with SSD drive and 2TB drive.For the last 6 months, I'd get kernel errors every now and again, and I would reboot and things would be fine. A few days ago, the computer totally froze, and when I turned it on, it would shut right off. I tried booting to recovery partition, nothing worked. I took it to the apple store yesterday and they hooked it up to an external drive and then did a diagnostic test and the genius said it needed a fresh install of lion, that something was corrupting it. So we did that (for some reason though, it took about 4 tries for him to get it), and then I took the computer home and ran time machine.
Every thing worked as it should for about 12 hours, I did reboot a few times in that time. Anyways, now, it's back to where it was where I turn it on, there's a status bar on the bottom that fills about halfway and then the iMac shuts down. The apple genius said that a corrupt program/application might be causing that. I find this hard to believe ... I can understand a corrupt program crashing or not starting, but is it possible for that to not allow the computer to even turn on? The other thing is that when the computer crashed a few days ago, I hadn't installed anything new/etc .... ???
OS X V10.7 Lion :: IMac Won't Boot Up After Latest Update
May 23, 2012downloaded the newsest updates from Apple and now my computer won't start up. Goes to long in screen and won't let you type in pass word. Spinning Beach Ball of Death comes up and never stops.
I just keep shutting it down ( push off button on the back until it shuts off) and trying to start it again. Some times it will let you get a little farther, but always after 2-3 minutes it goes to SBBOD.
Lates thing I did was push option+command+S when I turned it back on and now screen is black and has a bunch of code. Been at this stage for 30 minutes now. It is not pluged into the internet at the moment.

OS X V10.5 Leopard :: Boot From USB Drive Using A Lion IMac?
Jun 29, 2012I'm looking to wave good bye to my MacBook Pro running Leopard and upgrade.
However, I need to keep a version of Leopard so I can run certain Audio Units that won't run on Snow Leopard or Lion.
I have made a bootable drive with Leopard on it, but I can't get it to boot on my iMac running Lion. It boots fine using the MacBook though.
Is what I'm looking to do possible any more, or do I need to configure the drive for use with a Lion machine somehow?
OS X V10.7 Lion :: IMac A1225 Crash Running AHT Then Goes Into A Boot Loop
May 1, 2012I have an iMac A1225 EMC2211 that is exhibiting some weird behaviour. After about 5 minutes of using it (cold boot) it will either have a kernel panic, freeze and go into a blue (bondi blue I think) screen, or shut down. I ran an extended AHT on it and after 10 minutes it shuts down (black screen) then goes into a boot loop (screen stays black and system chimes once every 2 seconds). If the system is warm it will not boot (goes to blank grey screen). The consol reports something with the NVRAM (havent had the ability to post the log yet).

OS X V10.7 Lion :: IMac Will Not Boot Past Logo And Spinning Gear
May 4, 2012My iMac will not boot past the logo and spinning gear (After a Rogue Amoeba update). I can't access the recovery disk I made on a flash drive. (Am I doing it correctly? - Hold down option while switching on? It just stays on the logo).

OS X V10.7 Lion :: Screen On IMac Started To Go Blank - Only Way To Recover Was To Re-boot?
May 23, 2012Some weeks ago the screen on my iMac started to go blank. The only way to recover was to re-boot. The problem got worse until the machine became un-usable. I tried everything I knew, including switching off and unplugging to reset the pram as suggested, but eventually took it to the Apple Store where the 'expert' reset the pram the old way holding down the cmd/opt/p/r keys on startup. Problem solved (why do Apple give bad advice to clear the pram?).
Something had corrupted the software that drives the screen. The only program that I could think might have done that was ScreenRecycler which I have now stopped using. However, the problem has started to re-appear, the only new program I have used is Audirvana which being a music program should not affect the screen.

OS X Mountain Lion :: IMac Running 10.8.5 - Applications Starting On Its Own After Boot Up
Nov 30, 2014I have a problem with my iMac which is running OSX 10.8.5. I think the easiest way to explain this would be to just give a simple example. For example let's say I have Excel and Word both open. I shut them both down. Then I completely shut down my computer. Power off. I go to bed. Next morning I boot up and guess what? Word and Excel are now running again, just as if I had never shut them them down.

IMac :: 27" Wont's Boot Up / Takes A Very Long Time To Boot?
May 15, 2010I 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.

Apr 22, 2012I have a Imac PPC with a 2Ghz processor and 1GB of Ram. I am running leopard 10.5.8. Recently i woke the PC from sleep mode to find a blue screen with only the cursor working. Using the internet, I determined how to get the PC booted in safe mode. I have used all the disk utilities at my disposal along with onyx and cocktail to try and fix what I believe is a startup problem. I hae booted the PC in single user mode and tried the fskc codes, which i believe is just the same as the disk utility. Based on my computer all permissions are correct and there is nothing wrong with the HD. The PC still will not boot normally. I have even done an archive and re-install of Leopard.

OS X V10.7 Lion :: 10.7 Won't Boot Unless Hold Option Key And Select Boot Drive
Apr 27, 2012Last week I finally upgraded from 10.6 to 10.7, but now my Mac Pro (2008) won't boot properly. It'll start to boot with the gray screen and the Apple logo, but then the entire screen goes gray and it just locks up there. However, if I reboot and hold down the Option key to bring up the list of bootable drives that works fine. I've checked my Startup Drive settings and the proper drive is selected. why it won't boot on it's own anymore? Holding down the Option key is getting old.

IMac :: Windows Aero Not Working In Boot Camp-2009 IMac GT120
Mar 28, 2009I think it worked at one point, but sometime around the point when I set up Fusion with the partition, Windows Aero turned off and is no longer an option in the display settings. I installed this driver with the modded INF to see if it would do anything, but Aero is still not an option. I also have issues playing some games in Fusion, while they work fine in Boot Camp.

Nov 1, 2009I'm using a 20" white intel iMac and cannot manage to remove a linux boot disc from the optical drive.At first, the only way that i managed to boot to the linux disc in the first place was from the Startup Disk menu in OSX. I could not even get to the Startup Manager ('opt' at boot) or boot straight to the disc ('C').Now i'm in a position where no matter what i do, the system boots to the linux disc. I cannot even force the startup into OSX to try to eject the disc from there. I've tried holding all of these keys/combinations at startup
View 3 Replies View RelatedIMac :: Weird Boot Issues On IMac Core Duo?
Oct 28, 2009Back in August, I did an OS update on my iMac, and the machine wouldn't reboot. I was able to reinstall Leopard by booting from a disk, and all was well for a few more weeks. The machine seemed to run normal, with the exception of 5-minute-plus boot up times. But within a few weeks it stopped booting. I installed Leopard on an external HDD and figured I'd leave the internal alone until Snow Leopard came out.
A few weeks later when SL was released, I booted from the install disk, found the internal HDD, and went through the installation process. Everything went fine but the machine would not boot. I installed SL on my external HDD running Leopard, and everything was fine. I've since been running my computer off the external.
The internal HDD no longer shows up on the desktop, in Disk Utility, etc. I'm fearing it may have died. More worrisome, though, is my machine doesn't always boot up, whether from my external HDD (set as the startup disk) or from CD. By "doesn't always boot up," I mean most of the time when I restart, it just sits on a gray screen, nothing happens (even when holding "Option" or C.) Sometimes it will boot, but takes 20 or 30 minutes to do so.
I'm considering replacing the internal HDD, but am curious, does that seem like the issue, or might the failure to boot from externals and CDs indicate a more serious problem?
IMac PPC :: Imac G3 Installation Of Tiger Cd Won't Boot?
May 14, 2012I 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?

OS X :: IMac Won't Boot With 4GB But Will With 3GB?
Apr 7, 2009When 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.

Nov 18, 2009I 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!

Jun 8, 2008iMac intel core duo...
My computer had 1GB of RAM, so I just bought a 2GB RAM card. When I installed both cards together i can hear the hard drive start up and then nothing, no boot up, just a black screen and the "sleep" light is just solid. I know both cards are fine because I tested each by themselves and they both started up and worked well, its only when they are both in at the same time does it do this. also both slots work because i tested both of them! I tried to do the PRAM reset and it doesnt work, and I tried to do it with one card in and then reset and then shutdown and install the 2nd card and still nothing. Please give me some advice, i am soooo frustrated!!
IMac :: Won't Boot - Hdd Failure?
Dec 11, 2008The 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.

I started in safe mode and ran fsck but it seemed to take forever (hours) and never finished.
