Software :: Can't Get Past Gray - Need To Restart Computer Screen

May 12, 2010

I have a few month old iMac 27" i7 quad core for music use and did an update this morning which consisted of an itunes update and update to the screen firmware and two other things I can't remember. Do the usual install and restart business and am now met with the following error:

Software :: Stopped Booting - Gray Screen - Restart Computer

Jan 22, 2010

my dual 2.3 ghz G5 power mac with 3.5 gig memory running 10.4.11 started crashing (grey screen "you must restart your computer...) and soon stopped booting. suspecting the hard drive as it had been noisy for some time I ran "repair disk" in disk utility from my mac book (connected by firewire, G5 booted as target) and it booted again but soon crashed again and after a couple more crashes it would not boot and attempts to repair failed. I installed a brand new hard drive, installed osx 10.5 and updated it to 10.5.8 and it seemed to install and boot fine but while trying to burn a .dmg dvd with toast (10.0.5) I got the grey screen anain and repeated attempts to burn a disc with the same .dmg resulted in a crash every time. it has also crashed while downloading, playing back itunes hd video, and using an "eye tv hybrid" tv tuner as a dvr. below is the most recent crash log - note that most of them have referenced cpu 0 although the most recent it's cpu 1 -THANX & PLEASE HELPInterval Since Last Panic Report: 0 sec Panics Since Last Report: Anonymous 4A58CF1E-844-409F-8BF3-65A3A3CD2E79.......

MacBook :: Won't Start Up Past Gray Screen

Aug 2, 2010

first i'd like to give you a few pieces of information on what was going on before I restarted my mac. 1. My mac is a 13'' late 2008 mb with 2gb of ram (running leopard). 2. I JUST had my hard drive replaced due to a failure. 3. Before i restarted my computer i was having several "system extenstion" errors and when i tried to repair i recieved the message 'Underlying task reported failure on exit.' At the time, i was also trying to install Adobe CS5 Master Collection trial and i couldn't get past a password screen. This also prompted me to restart. Once the computer began to restart, it began updating boot caches. This was taking a very long time so i walked away from the mb. When i came back i realized the battery had died and when i plugged it back in and tried to get it to boot, it would get to the gray screen with the apple and the spinning logo underneath. But then it simply reboots.

I've tried restarting the pram. I've tried rebooting in single user mode (cmd + S) and got to the point where i could rebuild the tree (fsck_hfs -r /dev/disk0s2) and that did it's thing for about ten minutes and it didn't fix the problem. I don't have my install disk but apple is sending me a new one and will be here by friday.

Power Mac :: G4 Won't Boot Past Gray Screen

May 30, 2012

I have a mirror door g4 power pc that had been having some issues with not turning on, and after testing the power supply, it failed miserably. We placed a refurbished power supply in it from a company in New York and the computer was working wonderfully. I went on a cruise last week and went to turn the computer on for the first time in a week and a few days. The CPU turns on, the unit chimes, the fan turns on and the computer starts to boot up, but it won't boot past the gray apple logo screen. Actually, the first few attempts to boot it resulted in a blue screen with gaint apple logo and spinner; it wouldn't advance further. After several restarts and resets, I got it to come up into the normal gray screen. On several attempts it wouldn't boot further than this. On two occasions now though, it has moved past the gray screen to normal operation (it takes about an hour for it to get to that point though) but with some kind of errors. I get the side bar, but the gray panel on to with "file" ect is gone and my HD icon never comes up. The icons on the sidebar do not respond when clicked. The computer will not boot from the OS X disc.

PowerMac, Mac OS X (10.4.8)

MacBook Pro :: Won't Boot Past Gray Screen - Tried Basics

Nov 24, 2010

So bare with me I want to be thorough so hopefully someone can help me out. My MBP (08) will not boot past the grey screen. The wheel just spins infinitely. I've read about it trying to figure it out.

1) I tried to boot from the install disc, when I do there are weird diagonal lines and the thing is unreadable.
2) I hooked it to my Mac Pro in target disc mode. I was able to get some of the information off, but it would eventually freeze up and freeze the finder on the Pro. It wouldn't verify the disc in disc utility. It would freeze if I tried to repair the disc.
3) It won't boot in safe mode or single user mode (CMD + S)
4) I tried removing the ram and switching it and using only one stick of ram (to make sure it wasn't a ram problem).
5) I tried to boot without the battery

Needless to say I am a bit frustrated. My applecare is long gone and there is no apple certified repair place anywhere near here. I've also noticed the thing is very hot. If nothing else I'd like to have an idea of what I should be expecting from the repair place.

PowerPC :: IBook Won't Boot Past Gray Screen

Dec 30, 2010

I'm trying to resurrect an iBook (translucent white case, 14.1 LCD) that was long neglected, so not sure on its past service history. The following do NOT work: - won't boot up past the gray screen with Apple logo and spinning gear icon (just hangs) - same problem if I try to boot from install DVD ("c" or using "option" then selecting DVD) - same problem with safe boot with "shift" - reset PRAM It will connect via firewire target disk mode to another computer, and I used that to completely wipe the disk and do a clean install of 10.5. When I tried booting into single-user mode (cmd-s), it fills about 2/3 of the screen with normal-looking messages, but then hangs after this (no keyboard response): Got boot device = IOService... [various other stuff] BSD root: disk0s6, major 14, minor 5 I'm out of ideas. Any suggestions? The machine is old enough that it's probably not worth the diagnostic fee of the local Apple shop. Since I can't get it to boot, I can't even run TechTools.

PowerPC :: G4 Silverdoor Does Not Get Past Gray Boot Screen

Feb 6, 2008

At the tech dept we have this G4 that refuses to boot past the grey screen with the rotating wheel. The logic board has been replaced, we've removed all sticks of RAM save 1x512, we've tried a known working optical drive, replaced ribbon cables (optical cable was frayed on one end) No dice. Option booting works, but once we select the DVD we can't boot from an install PPC CD either, it just gets stuck at the grey screen. We also have a tech HD inside that the computer does not boot from either.

PowerPC :: G4 Won't Boot Past Gray Screen With Apple

May 1, 2009

I recently required a Power Mac G4, and it was working fine, albeit a bit slow but I just assume that was because there's too many files on it, but that's another story. I shut it down before I left work, when I came back in the morning it was just the grey screen with the apple. I reset it, still no response. I reset the PRAM, nothing. I tried to boot in Single user mode, nothing. I tried to boot in verbose mode, nothing. I force ejected the CD and put in an OSX disk one from my laptop, asked it to force read by restarting and pressing "C" and still nothing. I am not sure if a cable inside has been jarred lose.

PowerPC :: G4 15" Won't Boot Past Gray Screen

Jul 17, 2010

I was given a PowerBook G4 15" today. I need to fix it, but I can't find out what exactly is wrong. I've used MROOGLE and I can't find any problem quite like what I'm experiencing. In my case, the laptop will turn on, make the chime, and stay stuck on a white/grey screen. No apple, no spinning gear, no nothing. Just a blank white/grey screen. However, when I insert the Leopard DVD and hold down "C" the apple appears as well as the little spinning gear. That goes on for a few minutes. BUT, after those few minutes are up the small gear still spins, but the Apple logo is replaced with a prohibitory sign (like what you would see on a non-smoking or no parking sign) and it sticks there and sometime says that I need to re-start my computer. The same happens with the Tiger disk. Also, when I place the Leopard or Tiger disk in the SuperDrive and hold down "option" so that I can boot OS X from the DVD, I click the little continue arrow and nothing happens. I've reset everything there is to be reset, and I've opened up the computer and re-seated everything that could possibly be re-seated. RAM, HDD, all connector cables, etc. There isn't any visible physical damage inside of the computer either.

The most recent thing I've tried was to boot off of a PPC-specific Ubuntu disk. It does some stuff and lets me run the kernel, but after that the computer gets stuck on a black screen and does nothing at all. I'd really appreciate it if you all could offer some advice as to what may be wrong. All suggestions and ideas are welcome too.

Power Mac G5 :: Won't Boot Past Gray Screen With Spinning Gear

Nov 23, 2007

I started this topic on the Garage Band forum because I was having trouble with Garage Band '08 when my computer crashed and will not restart afterwards. Garage Band was crashing 2 out of every 3 attempts at recording, and I would have to use Force Quit to escape and start over. Then, while I was in the middle of a very complex project involving Garage Band, iTunes, Finale (music notation program), and Microsoft Word, the computer froze up and I hit restart, thinking that would solve the problem. Big mistake - the computer has not been able to restart since then. I have a late 2005 G5 power mac with 1 GB of memory, 230 GB hard drive (or something like that) and no additional gizmos installed, running OS X 10.4.4. I had upgraded to iLife '08 a month or so ago and have had problems since with unusual crashes and freezes, especially involving Garage Band '08.

When I boot, I get to the gray opening screen with the gray apple logo and the spinning gear (is it really called an "intergalactic frisbee?"), and no further. The fans come on (and begin to ramp up to a huge noise after two minutes or so), the white LED light comes on steadily. I've disconnected all peripherals except my keyboard and mouse (Kensington USB keyboard and Logitech Mouse, both of which seem to work OK still). I can use the keyboard to open the CD/DVD player, and I can start the computer with both the Apple Installer disk and with Disk Warrior 4.0. I've repaired everything I can find with both programs, verified everything available, used Disk Warrior to examine corrupted files, and removed all the .plist files that it said were broken and could not be fixed. The only thing I can't find is that it says I am missing a "tmp" folder in my HD/private/ folder, which I can't seem to locate on the directory on Disk Warrior. Both programs say that all my hardware is fine, and that everything else is OK too. Puzzling. I removed the battery and tested it (it was OK), replaced it, and reset the PMU button on the motherboard even though I know all you have to do is unplug the back for a few minutes or so.............

MacBook :: Won't Boot Past Gray Screen And Spinning Wheel

Jul 23, 2010

I apologize for the long message but I want to be as detailed as possible. My MacBook (purchased early 2006, white 13", upgraded to Leopard about a year ago with no problems until now) will not boot past the grey screen and spinning wheel. Here' are the list of 6 steps I've followed so far and still is not working. Oh, and I do not have any peripherals attached to my MacBook:

1. Reboot in Safe Mode: tried pressing down the Shift key before the powering up sound AND after the sound. Could not get into Safe Mode. Did this several times, holding the Shift key for as much as a minute or two. Nothing but grey screen and spinning wheel.

2. Reset NVRAM/PRAM: CMD+R+P+Option: Computer restarted but still goes into Grey Screen, spinning wheel and stays there forever.

3. CMD +S: I read this online. Gave me a black screen with a lot of information, but I don't know how to read the computer jargon, let alone know what to do with said info. 4. Disk Utility Repair Disk : Inserted my Leopard install disk. Went to Utility Disk. Performed a Repair Disk and I did get two error messages, something related to id 70000452 should be id 70000450 ( I'm sorry to say I cannot remember the exact error messages). But it showed as repaired. When I did a 2nd Repair Disk, I got the message that the volume appears to be OK. Turned off and on again, nothing but grey screen and wheel.......

OS X V10.7 Lion :: MacBook Suddenly Won't Progress Past Gray Screen

Apr 28, 2012

My macbook suddenly won't progress past the grey screen and the spinning gear. I have tried the procedures listed in one of the support documents, although I note they don't include OSX10.7 which I am running. I got to the part where it says try your system disk, problem is, I purchased through App store.I'm guessing at this stage I should have created an emergency boot disk.

MacBook Pro :: Unable To Boot Past Gray Screen - Reset Pram

Jan 8, 2011

My macbook pro won't boot past the grey screen, I've tried reseting PRam, running fsck from single user etc to no avail. All signs would point towards a hard disk failure, but the curious thing is that it sometimes mounts in disk utility when booting from the install CD, so theres a little life left in it yet! I have fairly recent backups of most of my files, but there are a couple I've been working on in the past few days that won't be backed up. So my question is this - is it possible to copy files from my mac HD onto a external drive through the terminal/disk utility while booting from the CD.

MacBook :: Won't Boot Past Gray Screen With Apple Logo And Then Shuts Off

May 29, 2012

This morning, I would turn it on and it'd go to the grey screen with the Apple logo for a few seconds and then go to the icon that is a circle with a line through it. After reading online, I was able to boot it up in Safe Mode. I went to Startup Disk in Preferences. I chose the MAC OS X, xxxx and then clicked the lock to prevent further changes and then clicked restart. Now when I turn on the macbook, it goes to the grey screen with the Apple logo for at least two-three minutes and then just shuts off. Won't boot into Safe Mode now. I already tried the Command-Option-P-R keys trick like five times.

MacBook Pro :: Does Not Start Past Gray Screen / Apple Logo And Rolling Circle?

Apr 26, 2012

My Macbook Pro is not starting past the grey screen and the apple logo and the rolling circle. I have tried every method and I am desperate to do anything to start my computer even erase the entire disc. I have contacted the Apple store and they told me the cost will be equivalent to $600 to just repair it and no way I will be able to afford it.I am willing to do anything and even erase my entire disc. However, for that the instructions on the Apple page state that 'Insert your Mac OS X 10.4 or 10.5 installation disc'. However, I do not have my installation disc Is there any other way I can erase the OS system and at least reboot my Macbook?

Mac Pro :: Get A Matte Gray Screen On Restart, OS 10.7.3

Mar 15, 2012

After installing updates, I restarted my Mac and it ends up with a matte gray (cloth-like appearance) with a gray Apple logo, but does not get to the desktop. I can open/close the DVD tray, and have cursor control, but nothing else seems to work. Short of reinstallation of Snow Leopard, what are my alternatives. I did the Lion update online but do not have a system disk, hence reversion to Snow Leopard is my only option.

OS X :: Screen Goes Gray & Message Tells To Restart

Jun 19, 2007

I'm frequently getting the problem that: many times the screen goes grey and a message box appears telling me that I have to restart. Often this is preceded by the fans gradually increasing in speed until they are runing at maximum speed. BUT the fans behaving that way is NOT due to overheating. I have to use the restart button to make the Mac restart. I have used reset button to reset the motherboard but that did not cure the problem. Anyone have any ideas about how to cure this problem? I'm running 10.4.9. The mac is a dual 1.8 (June 2004). 1.5GB RAM, two SATA internal HD�s (Maxtor), two external firewire HD�s (Seagate). All the HD�s are less than a year old.

MacBook Pro :: 13.3 - Screen Goes Gray - Restart System

Mar 23, 2010

Im new to these forums. I have just (5 months) purchased a new Macbook pro. I have upgraded the RAM to 4GB, but only recently since ive been in Canada (1 month) experienced this problem. The screen goes grey once a day and the computer asks me to restart the system. I believe its called a Kernal Panic. Ive read on other places that it might be caused by recently installed apps. But i have got rid of these and now nothing has changed! I havnt got my Install CD on me therefore cannot run a reboot. Im not sure if the issues are related but the Mac also kicks me out and makes me log in again. this doesnt happen as frequently but is still concerning and rather frustrating.
