Software :: Intel IMac Won't Boot Up - Freezes On Grey Screen Or Apple Symbol?

May 14, 2008

Got my 24" 2.4GHz iMac on release last year, with Tiger. Installed Leopard on it on release day.

The problem I have is that ever since a botched Boot Camp installation I've had endless problems with certain applications hanging during their startup (notably Image Capture) or refusing to quit (notably iTunes). Force Quit doesn't resolve these issues. Restarting doesn't work because Force Quit can't quit them so I have to pull the plug or otherwise force a shutdown.

Upon restarting I either get the grey screen that instantly appears, or, if I've pulled the plug and left it for a few minutes I can get to the Apple symbol but no spinner or any further start up action. Occasionally I get lucky, get back up and running, and all is well until the next crash.

All this started happening when I decided to try installing Windows on Boot Camp again. I've had it on here a couple of times since Leopard was released but usually end up deleting it eventually because either the Windows installation gets bogged down or I get bored with it and never use it. Anyway, this time, using the same discs I've always used (and yes, it's SP2, so it should be fine and anyway it's worked at least twice before) when I got to the 'restart to continue installing Windows' bit, I got the white screen and nothing happened. After an hour or so of praying and restarting endlessly trying to get a response, I finally got it to recognise my OSX installation and was up and running again. The Boot Camp volume didn't appear to be there and Disk Utility revealed zero problems whatsoever. Everything looked fine until these recurring hangs, refusals to quit apps and screwed up start-ups.

Any ideas? I don't have the expensive Apple support, but it's less than a year old! Of course, I realise that this means nothing to Apple, who seem to think I should pay a premium in order to have my machine warrantied by them for more than 90 days. Grr...

If I get it up and running I'm thinking I should just wipe the ENTIRE system absolutely clean and re-install Leopard and then use my Time Machine backup to put all my data back on (pricelessly valuable as I use the machine to work on my photography with), but I'm concerned that if there's a flaw in the System somewhere, a corruption, that installing the Time Machine backup will just reintroduce the error. On the other hand, if it's a deeply embedded and invisinle partition corruption from the bad Boot Camp installation attempt, that should be fixed by wiping the entire drive to reinstall Leopard, right?

Software :: A Grey Screen Fades Into White And The Apple Logo Never Appears?

Nov 23, 2008

I have had my MacBook for almost two years and the battery had just died on me. So I sent it back to Apple and got a new one. But ever since switching over to this new battery, my computer has had issues starting up. A grey screen fades into white and the Apple logo never appears. The computer will just stay like that for hours. A friend suggested turning the power off and back on, holding apple+ctrl+P+R, which worked.However, the next time I turned my computer on, the screen stayed white again, without an Apple logo. Can you tell me what the deal is? Should I bother reporting this to Apple? Is this permanent damage I'm going to have to go thru everytime I start me laptop?

OS X :: Mac Freezes - Black Screen Appears

Jan 21, 2011

G5 Power Mac, 4 gb RAM, OS 10.6. Machine freezes up if: I run a video (1st, 2nd one), use Safari for a few minutes, use Firefox for 1/2 hour, longer if I only have 1 tab open at a time. Occasionally, I get the black screen of death instead, with the #s running about the screen (white font), out of The Matrix. I've run Disk Utilities - RAM checks out okay, cleared out cache, switched to a new HD (old one had been there since I got the Mac, several years ago), these have alleviated but not eliminated the problem. A tech friend suggested thermal grease on the CPU, or replacing the CPU, but don't know if the latter's possible. Oh, and some part is missing that results in the fan running all of the time, like being on a runway.

OS X :: Mac Freezes At Grey Screen?

Jul 29, 2010

So yesterday my iMac froze while using iTunes. I had to manually power it off. I turned it on again and it booted fine. I tried iTunes again and shortly after that it froze again. I manually shut it down again. I tried to turn it on once again and it won't load the desktop. It just stays at the grey screen with the apple and spinning thing. I am pretty sure I have to erase and install again, but I am not really sure on how to do it correctly especially since I can't even get to the desktop. My OS is 10.5.8 and the machine is only 2 years old and hasn't really given me any problems before.

MacBook Pro :: Startup Screen With Apple Logo And Grey Loading Bar Then Unexpectedly Shuts Down

Jun 26, 2014

I have a MacBook Pro from 2010 I believe with iOS Maverick installed. (MacKeeper is also on there, which I just found out is apparently malware) 

So three days ago I was watching Netflix, the image froze, but the audio kept going. Figured my internet was slow, so I waited a little, nothing happened. pressed escape to leave the full screen mode, but nothing happened. None of the keys would do anything, not even the sound or brightness keys. So I did a force shut down by holding down the power button. 

I waited a little, then decided to turn it back on. Start up sound played, white screen with grey apple logo and loading gear appeared together with a grey loading bar. I figured that this meant it had to repair something. But after about a minute or two it just went to a black screen/ shut down. I left it off for a day, tried it again, same thing. Next day I tried booting it up while holding the shift key to do the safe boot (I knew it wouldn't work since I already had the grey loading bar anyways), same thing happened.

Laptops :: Unable To Complete Startup / Grey Screen With Apple And Spinning Wheel Appears

Jul 24, 2010

Hi all, I have two Powerbook G4 laptops. Both have very similar problems. When I try to start up, the grey screen with the apple and spinning wheel appears, but I can't get beyond that. If I walk away for an hour, when I come back there will still be a grey screen with apple and spinning wheel.

I admit I know little about this sort of thing, so I began poking around online for solutions. I tried Tech Tool Deluxe. Inserted the disk and held down "C," but again it never progressed beyond the grey screen with apple and spinning wheel. Most frustrating. Is there any other way of running the disk with the laptop?

Entering the terminal yielded slightly different results on each machine.

Powerbook #1: Once in terminal I typed...

/sbin/fsck -fy

...response was...

disk0s10: I/O error.
Invalid Key Length
(4, 44890)
** Volume check failed

...tried /sbin/fsck -fy over and over, always received the same results.

Powerbook #2: Once in terminal, this appears...

jnl: update_fs_block: failed to update block 1073777488 (ret 5)
jnl: journal_open: Error replaying the journal!
hfs: early jnl init: failed to open/create the journal (retval 0)

...and it won't even let me type /sbin/fsck -fy.

I tried plugging both latops into my desktop in target mode. In both cases the target icon appeared on the laptop screen but the hard drive icon never appeared on the desktop screen. I would love to at least retrieve a few files off each machine, if nothing else.

OS X :: Mbp Snow Leopard Freezes On Grey Screen?

Nov 1, 2009

I have had a string of bad luck with my mac, a couple of days ago the screen started flickering and my mac froze (could still move trackpad mouse, not click). It started up fine again.. It did this a couple times more (had to restart pressing power button). Then it froze evereytime I put the power cable in it. I solved this problem with an PRAM reset.

But now it still freezes up, the screen will start flickering and i can only move the mouse. When i try to reboot it gets stuck on the grey screen. only once every 20 times Ill get into the os.

I have tried a pram reset, holding the power button, safe mode, hardware test (no probs found), starting up without external devices.

It wont boot from the cd if it is stuck on the grey screen...

Could someone may be tell me what to do? thinking about bringing it to the store tomorrow .

MacBook Pro :: System Freezes Randomnly For 30 Sec - Gray Screen At Boot Appears

Jan 30, 2010

Since a few days ago my Macbook Pro 13" from last June started to freeze randomly for atleast 30 seconds and then it would come back and most of the time freeze again after a while (in OSX only it seems, Windows 7 I did not have such problems, though I didn't use it often). Sometimes it occured frequently, other times it didn't and this morning I had the same thing again, I just held the power button and shut it down, did this two times in a short period of time and when trying to boot it for the second time all I get is a gray screen with no Apple logo or anything.

Searched the forums, tried the install DVD and C button to no avail, same thing with trying to reset the PRAM and NVRAM...Is the logic board broken or anything? I don't understand how this could happen...And if I do take my laptop to Apple, should I remove the Intel SSD drive I got in it right now and put in the stock?

MacBook Pro :: Snow Leopard Startup Freezes At Grey Screen?

Mar 15, 2012

My Snow leopard machine hangs during startup at the screen with the Grey Apple logo.  It appears there is a SW issue with my OS X boot partition.  Here are facts I have learned:The computer boots fine if I hold option at startup and select my boot camp partitionThe compute boots fine if I attach an external HD with OS X 10.6Running a disk repair from the external HD, I see the following two issues that are repaired.  Also, note the last line about boot partitionsAfter this disk repair, the disk will still not boot, it hangs at the Grey Apple logo.Booting in safe mode does not resolve the issue, the machine will still not boot to a desktopBooting in Verbose mode, drivers initialize with the last succesful line being the ethernet drives (I believe) and then the hangup occurs.  It is unclear what state the boot process is at on the hangup. 

This situation has happen twice in the past few weeks.  The first time I did a reinstall of OS X to resolve the issue.  Then, the issue appeared again approximately two weeks later.  I'm hoping to avoid a second reinstall (And really, avoid this issue in the future).  It seems perhaps something in the boot partition table or the OS partition, although disk utility says the partition is fine.  I have downloaded Test Disk 6.13 to look at the partition table, but I don't know how to interpret the outputs of that program.

Hardware :: Noticeable Shading On Screen Display?

Feb 4, 2009

Has anyone ever come across this weird shading before? I've only just noticed it on my display, and while it is not noticeable when loads of windows are open or when there is a complex photo, it does show up when the background is plain like this. It doesn't appear to be a backlight problem, and I cannot see that it would be a pixel problem.

Intel Mac :: Put A DVD In And It Was Still On The Grey Screen?

May 12, 2012

I came home to find my IMAC stuck at the grey apple screen with a circle of dots spinning...I've been trying to piece together the events that led up to this:

1) The night before I ran some updates including the osx 10.7.4 update and then selected restart and went to bed

2) THe next day my son says that they tried to put a DVD in and it was still on the grey screen...they inserted the DVD anyway

3) I tried unplugging etc and then rebooting but same grey screen

4) I rebooted with the track pad held down and it managed to eject the DVD

5) Now when rebooting i get 3 bleeps repeated, I've retried this a few times and its the same

6) I have rebooted using CMD R and see that the Macintosh HD is listed showing 466 GB free which I hope means that the other 534GB is still on there...not sure if I should repair it 

I've had this IMAC since January and am ashamed ot say that I DONT THINK I HAVE A BACK UP yet...I was ust about to buy an external HD big enough to back it up so VERY CONCERNED about losing my recently uploaded entire family home movie collection as I speak my wife is holding back the tears..

IMac (Intel) :: Shuts Down During Load Up Screen

Aug 24, 2014

I just got home and I realized the power was out. I bought this iMac literally like two months ago (I actually bought one two months ago but it wouldn't even turn on so they gave me a new one) It was working perfectly fine, and I was writing a report. I left the computer on and left the house only to return hours later with the power out, and when I turn it on it shows the start up screen with the Apple Logo, the little progress circle, and a progress bar that fills up to the end everytime but once it fills up to the end it stays there for a few minutes then the computer shuts off.

Intel Mac :: It Has A Grey Screen And Won't Boot From HDD

Mar 24, 2012

I have an imac from late 2008 with snow leopard. Late saturday evening 24 Mar I had powered down my imac then later turned it on. Now only a grey screen appears, nothing more. If I leave the imac on a folder with a question mark appears and blinks.I have tried the following to fix the problem and ALL HAVE FAILED:they are:

1. resetting the pram. it doesnt work.

2. booting from the installation cd. The imac doesn't even READ the cd, the screen remains grey and doesn't read the cd at all.

3. booting in the safe mode. nothing happens, the screen remains grey.

4. booting in apple hardware test mode: nothing happens screen remains grey.

5. boot with option key pressed, so as to choose mac HD or my windows partition. nothing happens, the screen remains grey.

When I power on my imac I heard the chord, a slight spin of the HHD I'm sure that's what it is,and then nothing.grey screen.I have tried unpluggling the power cord for 15 seconds, reconnecting it, waiting five secondsand then powering up the imac. it doesn't do any good.do you think it is a hard drive error or failure?  why doesn't it read or boot from the instillation CD??  and yes I am using the correct disk.

Intel Mac :: It Stuck At Grey Screen

Apr 18, 2012

everytime I try to boot my iMac it gets stuck at the first grey screen. No logo, no loader, nothing but a grey screen. I have tried everything here > http://support.apple.com/kb/TS2570 > with no results. The grey screen remains there, with no changes. The only thing that seems to work, but only for a seconds, is holding the option (alt) key at startup. After a few seconds, the pointer of the mouse appears.
