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.......
I just bought a iMac M5521 from a friend and it won't boot. It looks like it's about to start up and then it goes to a gray screen and tells me to press the reset button or hold the power button, and it says that in like 3 diff. languages. What do I do? I'm a PC guy and know nothing about Macs.
i have a macbook pro 15' late 2011 and it stopped booting. The apple disappear and the. It get stuck in a gray screen.I saw on the web that it would be possible to apply a software fix, disabling the video card. IN my country a new macbook is about 3.000 usd, so buying a new one is not an option for me.Â

im getting a message on a grey screen asking me to restart my computer when i'm trying to start my imac? So, i hold down the on / off button to do a hard restart and i get the same message again.
My computer has started randomly popping up a grey screen which tells me to restart. It keeps happening and obviously something is wrong. Not sure if it is a hardware failure but something's broke! Anyone know what the deal is? Here is my latest panic log:

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:

I started up my iBook today and it took me all the way through sign-in to my desktop before giving me a grey overlay with a little box saying that I need to restart. So I did and then it took me to my desktop again before scrolling code across the screen in a very messy, un-mac-like way. I tried getting into safe boot (restarting and pressing shift from after the tone until the apple and wheel show up) and it just ran the apple and wheel grey start-up screen for a while before kicking back into a normal restart and giving me the earlier results. So I went and got myself into single-user mode and ran the fsck -yf command. It told me this: Checking Catalog file Invalid extent entry (4, 190) Volume check failed Is there any way to fix this, to save my computer? I don't know anything about code or computers. My general mode of operation has been "I bought a /mac/. I shouldn't ever have to look at code."
I started up my 24" iMac today and it just got stuck on the grey screen before the apple logo appears. I reset the PRAM and I tried using the OSX disc and holding down C. I got to the disk utility and it freezes. I am stuck using my bottom of the line laptop untill I can work around this.
I just purchased Windows 7 to dual-boot on my brand new 2010 MBP. After I installed Windows 7, I inserted my MacOSX Snow Leopard install DVD so I could install the drivers. A message came up saying "This installation isn't compatible with this computer". So I restarted my computer and when it was booting up it gets stuck at the grey screen with the apple logo and rotating wheel. After a while a grey curtain comes down with a Power Icon in the background and a window saying "You must restart your computer" in a variety in languages. I tried restarting and the same screen comes up every time. I've tried all the boot key commands such as holding shift. But each time it doesn't recognize it and proceeds to the grey screen of death. I'm completely stuck here and need help ASAP. I would like to do a hard reset on my MBP, but I can't since I can't boot to MacOSX and when I boot to Windows 7, it runs for about 2 minutes and completely freezes, causing me to force restart.
When booting up on my Mac Book Pro side it gets stuck on a gray screen and wont boot even when in safe mode. I have cleared the P/Ram and still have acces to the partioned windows side on the same computer. How should I procede to get my Mac OS running again.
Got a tricky one here: powerbook G4, 1.25ghz, 1GB RAM (2x512), 80gb HD, APX, 15" LCD, serviceable battery, SuperDrive, OS: 10.4.11. It was brought to me with a boot problem: Computer turns on, gives the start up sound, backlight comes on, apple logo shows, spinner spins... then you get the dimmed screen, large option icon and "You must hold the power button and restart your computer": a kernel panic. I've seen this a few times before and the last time, I fixed it with a new hard drive and the removal of RAM from a bad ram slot.
What I did was: 1) Replaced existing 80GB HD with a backup 30GB drive. Then booted with a Tiger CD (the computer won't start with my disk warrior cd, nor with a tiger DVD). I was able to install Tiger and restart the computer. But the airport card doesn't show up. I tried a known good airport extreme card and this too has not shown up. 2) I hooked up the 80GB drive to my PC via MacDisk and checked it. Sure 'nuf it had loads of problems. MacDisk went through and fixed it (I'm not sure what the problems were as I'm new to MacDisk and don't know what it's looking for and fixing when it does). 3) With the computer running the 30GB known good HD, I started having the same kernel panics so I removed the first RAM chip (512MB) and tried to reset the PRAM.... here's where it went wonky. (I know, only change one thing at a time...) 4) As I said I tried to reset the PRAM (Option, Command, P, R, at start up). While I can get the computer to not boot, it won't restart. I don't know if this is just unique to this machine. Next I tried to reset the NVRAM and again got nothing. The screen wouldn't come on at all. After about three or four resets, the computer did start in Open Firmware mode. I reset the NVRAM from there and restarted (reset-nvram, reset-all). Still nothing on restart. 5) After trying to start it 15 times like this, I swapped the bottom RAM card to the top slot and removed the airport card (again, I'm stupidly trying to change two things at a time). BAM, computer boots... I put back in the 80GB drive that's been "fixed" by MacDrive and BAM, that boots fine too.
So then I put back in the airport card and it will boot, but won't recognize the airport card. I've re-seated it about a dozen times and have used terminal cleaner on the card and on the socket for the ribbon cable from the card slot to the logic board. As it sits, I can't get the airport card (either of the two) to show up at all. I did realize that the open firmware did reference a problem, but I forget the code now and when I looked it up, the references were to a failure of the airport card, but there were also more general references, so I can't be sure.
I'm thinking now that it's the airport card controller on the logic board, the bottom RAM slot and a corruption of the hard drive. Yes, there was a history of moisture into the device and I think a drop in it's past too. I'm the Mac repair technician for the people at the local bike shop, so I get to trade my repair work for their bike repair work. The problem is that they ride their laptops like their bikes, hard and greasy. I'm really wondering about ways to get the airport card back up and running. Or, baring that, a good card-based wireless adapter that I can slide in.
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.Â
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.
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.
bought a new i mac and while using had a gray screen scroll down slowly and then said I had to restart the computer it is now happening more ofter and do not know what is causing it
I recently noticed that when I shutdown/restart my MBP, i get stuck in a gray screen with spining wheel. I can't remember if and what i instaled, but I know that this problem happens when I open up ITunes and keep showing up even when I close/force quit manually ITunes.
When I restart the mac with the command "reboot" of the finder. I have a gray screen and nothing more. If I use the command "Turn off" and I turn on the mac by the start button it works.
My mac wont on (goes to black screen) after a gray bar that usually shows after restart has been loaded. What should I do?I already tried the safe mode and it's not working ...
A friend of mine brought over his 14" iBook G4, 1.33GHz, 60GB HDD and 1.25 GB RAM. The problem with it is that upon start-up, the grey screen with the apple/turning gear comes up, then after a few moments a blue screen will appear, though no box showing the start-up process. I've run a few basic diagnostics on this, including the lovely disk utility (which did nothing), I've run fsck, zapped the PRAM, etc, no success as of yet. At one point, I received a screen with alternating folders, one showing the smiley mac face, the other folder with a flashing "?". I cannot replicate this for the life of me. I have attempted to acquire files via TDM, though am not able to see the hard drive despite using 2 different laptops. Possibly the firewire cable itself is spent, though it's brand new! Here is where I become increasingly frustrated: I ask my friend for the boot disks as the ones for my own 12" iBook don't work (for whatever reason). He tells me that he loaded Leopard this summer (currently running 10.5.2, no updates loaded since), then proceeds to bring over boot discs for a MacBook...:headdesk: To begin with, it seemed like the HDD was fried, however, after running disk utility (and not hearing any negative sounds), it does appear that the HDD is fine. I'm thinking a kernel panic, though not sure how to resolve these.
I have been trying for weeks to do a software update from 10.6.7 to 10.6.8. Whenever I install the update and restart my computer, I get the apple logo loading screen and then it locks up on the infamous blank gray screen. I have been able to get back to 10.6 with the install CD, and can then update all the way to 10.6.7 I have tried everything listed here:[URL]To no avail . including a clean install When I start up in verbose mode the last line of text I get is the following, after this it's the gray screen:
** Device in slot: SLOT--1 ** RBIOKitController found 0x5ac :0x842Â Those last two chunks of numbers change each time I restart. Â
In fact I'm getting a grey screen when I just try to restart. Have run Disk Utility (which always finds Permissions errors - even though it appears to make repairs. Also, after erasing my hard disk and recovering my user data from Time Capsule). When I restart I don't get beyond a grey screen (with moving cursor). I can't install the update as obviously I need to restart in order to start the install process.
My Macbook pro is not booting properly. When I start it up, it goes through the normal process and gets to a point where a screen comes up telling me: "You need to restart your computer. Hold down the Power button for several seconds or press restart now" This happens every time. I tried to start in safe mode and holding down the option key and selecting the mac partition. Neither would work.
I have a 20" iMac G5 1.8 GHz which has been pretty reliable since new. A few weeks ago I fitted a new Hard-drive (Western Digital Caviar Black 1TB), other than that the computer is bog standard. For the last few days when I start up, the computer switches itself off straight away and I have to press start again. Sometimes it gets as far as the grey screen and sometimes it gets to a complete desktop screen before this happens. This may happen 2 or 3 times and then the computer works fine all day, I can even restart with no problems once it is running fine. As it stands I can live with the problem but I worry that it may get worse. Anyone know what this might be? Could it be related to the new hard-drive? Could it even be related to the cold weather?
While working on the computer, sometimes the screen will turn gray (from top to bottom) and a message will appear saying the computer must be restarted.So far the local Apple store has not been able to find the problem. The last solution the store tried was to replace the Airport Card, but that didn't work. Computer was purchased in December 2011.
After the computer has been in sleep mode for a little while, when i try to wake up the computer, it turns to a cray scree, a loading bar appears and then it takes like 5 mins for the icons to appear and for the mouse to work!

Allright so my girlfriend accidentally spilled a drink on her macbook the other day. We thought we had cleaned it off and everything was fine. We were mistaken. During normal usage the computer crashed so we restarted it and are now greeted upon startup with a gray screen and a gray application folder with a question mark on it flashing repeatedly. What is the course of action guys? I'm not computer whiz and I'm wondering if we can fix this ourselves without having to take it in for repair. And FYI she does not have apple care
