MacBook Pro :: System Hangs At Apple Logo Boot Screen / RAM Not Allowing System To Boot

Jan 5, 2011

I've been reading this site for a while now, first time I'm posting. I recently purchased 8 GB of RAM for my 2010 13" MBP. There are two 4 GB DDR3 PC3-10500 1333mhz sticks. When I install them in the laptop my computer does not get past the apple logo boot screen (the spinning disc freezes). However, I can boot into Windows (boot camp) without issues.

Also, when I pair either of the 4 GB sticks with one of my old 2 GB stock sticks the laptop boots up fine in OS X. The system profiler registers it as 6 GB of 1067 mhz RAM (the stock sticks are 1067 mhz)

OS X :: Apple Grey Screen And Hangs, Gets To The Login Screen And Hangs?

Jul 13, 2010

I have a much loved ibook G4 14" (late 2004??). It has just died. Well, in so much as it won't boot up. The ibook either gets as far as the apple grey screen and hangs, gets to the login screen and hangs, actually loads up finder etc and hangs or none of the above. Sometimes flashing red, blue green black.

After lots of research online over the past few days I tried the following: I have tried safe mode (not working), starting the command prompt screen (single user and verbose modes), started open firmware, and tried booting from a CD. Nothing works as the boot gets so far then hangs. I have flashed the PRam, resetted the NVRam, and have stopped short of opening up the case to dismantle it!

I just really want to access the hard drive now. I have tried Target disk mode and linked the ibook (pressing T) via firewire to a PowerPC G5, but the G5 doesn't recognise the ibook. System profiler on the G5 shows the target mode connected and working fine via firewire, just the icon for the ibook/target doesnt mount on the G5 desktop so I cant access it.Currently the boot freezes within a couple of minutes.I tried the hardware test CD that came with the ibook years ago, I have also tried booting from an OSX Panther CD. I'm assuming they would be bootable.

I forgot to mention that in linking with the G5 in target mode, a disk that I put in the ibook drive appeared on the G5 desktop as an external drive, therefore I wonder why i cannot see the actual ibook drive mounted. The CD drive works as it mounted on the G5.Does the ibook have an actual PRam battery that can be replaced? Maybe this is an issue?Am I able to actually remove the hard-drive and access it as an external drive somehow?

MacBook Pro :: Unable To Boot System / Grey Screen Of Death At Startup

Oct 1, 2010

The other day my 1st gen MBP functioned without any probs, until it suddenly powered down. After I removed the question marks from my eyes, I offcourse tried to reboot it.

But it never makes it beyond the grey screen, sometimes untill the apple logo, sometimes not even that far.
Offcours I googled around first to gather some info before I decided to put this problem down on this board. I found this could be a HDD failure, but in those cases, with other people, it could be powered holding apple + s, and doing some checks that way.
Mine doesn't even come that far

I have a second hand 1st gen MBP with upgraded HDD and RAM, snow leopard, and coincidently since last week no more battery... so i may have powered down a completely unprepared mac by tripping over the wire, once or twice...

OS X :: Unable To Boot System / Grey Screen With Apple Logo At Startup

Jan 12, 2011

I own an iBook G4. I could not get it to boot up, it would just go to a grey screen with the apple symbol and a timer/clock that looked like a gear.FYI: I may provide more information than necessary in the text below. I'm not sure what is and isn't relevant.

Following some advice I found in this forum I got out my old OS disks to boot from the disc instead of the hard drive. I intended to archive the old hard drive and install my latest OS (10.4.6 on the disc, 10.4.11 was the version I had been running on the machine, I believe). The machine told me it needed 4.5 Gb to install 10.4.6 Tiger, but I only had 4.0 Gb left on the hard drive. So instead, I archived and installed with the OS that came with the computer originally, 10.3.4.

I got things going, did the archive and install, and got to the log in screen. Unfortunately, I could not remember the password, so I booted up in single user mode, and entered the following to get into the machine:

1. mount -uw /
2. rm /var/db/.AppleSetupDone
3. shutdown -h now

This got me in with a new admin login, and I started up in 10.3.4. I soon noticed that I could still see all of the files that I put on the hard drive on my old operating system. I thought I shouldn't be able to see them, but since I could I decided to try to copy them to an external hard drive. When I did, I got an error message saying that there was a read/write error. I was not entirely surprised, but I decided it was time to turn back to the forums for help.

What I want to do is copy everything from my old hard drive onto an external hard drive, make room on the iBook hard drive to reinstall my latest operating system (10.4.6). Once I've done that I'd like to get the essential files back onto the iBook from the external hard drive and continue using my computer (even though it is a dinosaur).

Hardware :: System Freezes Or Hangs On Boot / Startup

Apr 27, 2008

I have a mac pro running leopard (purchased in 2/08) and it was running beautifully for almost 2 months with no hangs, crashes or freezes. Then, for some reason, today when I turned it on, it would not boot. It would get to the apple logo, then just sit there for a few minutes, then reboot itself and the same thing would happen. I pulled out the ethernet cable, unplugged all usb except keyboard/mouse and it would then (sometimes) boot into the system, log me in and present me with the UI.

I then quickly performed a soft reboot and it would get to the desktop. However, I can only use it for anywhere from 30 seconds to 5 minutes before it would completely lockup. The clock freezes, the mouse freezes and it just sits there forever. I have tried booting into Vista (BootCamp) and it also freezes before startup is complete. If I hold down Option and then select the System disk, it will either just hang forever or get to the desktop and then freeze again....................

Aug 29, 2009

When my son's computer is turned on it just goes to grey screen.. I've tried a number of troubleshooting things...starting while holding "c" to boot with install disk...starting holding "shift" for safe boot. I did the PRM (?) reset thing holding Apple-option-p-r keys while starting and that did add the start up chime...before it would just go to the grey screen, no chime no spinning wheel...but still no boot.The computer is still under warranty but soonest appointment at Apple Store is 3 days from now!!!

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.

imac 2.8 ghz int core 2 duo, Mac OS X (10.5.6)

PowerPC :: IBook Goes To Grey Screen - Won't Boot / How To Fix It

Sep 15, 2006

I have seen this talked about a fair bit, but i thought i'd start my own thread because it seems slightly different.

To start, when the computer was last running, the (what sounded like fan) started making a terrible noise, then stopped, and the computer turned off.

After that, when booting, it just goes to a grey/blue screen and sits there.

I have an iBook G4, 1064mhz, 256/30.

I dont know what model that makes it, but from the Mac website, I have tried to reset the PRAM to no avail. All of the methods listed do not seem to do anything on my ibook.

I tried using this link to reset the [URL]

I dont know which one is for my model, but i see no reset button under the keyboard, or on the case. There is a little tiny hole on the case beside the LCD???

I have tried the shift-ctrl-opt-power but it doesnt do anything.

As well, i did hold down the "option" button when booting, and it brings me to a screen which shows an image of a hard drive with a green "x"

I dont know if the green means good or the X means bad..

I have read that resetting PRAM and/or changing the resolution seem to help the problem, but I do not know how to do either.

OS X :: Macbook Wont Boot Up - Getting Grey Screen And Pop Up

Jun 4, 2009

My macbook wont boot up for some reason. When trying to turn it on it goes to a grey screen and nothing pops up, eventually a little picture pops up that has what looks like a folder with a question mark in the middle. I then tried booting from the CD and when trying to do that a picture of the world pops up and then also the folder with the question mark in the middle. I thought i may have been the harddrive so i bought a new one and it still has the same problem.

PowerPC :: G4 Shows Grey Screen - Not Boot From CD Either

Jun 8, 2009

It makes the startup chime, and I've tried resetting the PRAM and PMU and none of it works. Apple store said they thought it was hard drive failure, but I doubt it because it won't boot from CD either. Do you think it's logic board failure?

MacBook :: Why Can't Boot Past The Grey Screen With An SSD

Apr 1, 2012

My wife has a Macbook with an Intel Core 2 Duo processor (Macbook4,1).  I am trying to replace the original SATA hard disk (160 GB) with an SSD.  I have two SSDs here with me: 

1) Intel 320 series, 160 GB

2) Crucial M4, 128 GB 

In both cases, after replacing the hard disk with the SSD, I am unable to get the Macbook to get any further than the "Mac sound" and grey screen. 

In my first attempt, I cloned the original disk to the SSD on another computer, verified the data got on there OK, and installed the SSD into the Macbook.  In subsequent attempts, I just formatted the SSD to see if the Mac would recognize it at all. 

When the original hard disk is installed, and my Snow Leopard install DVD is in the DVD drive, during the boot, I can hold down the option key and get a boot choice of booting from the hard disk or the DVD.  With either SSD installed, when holding down the option key I get no choices at all, it just sits there (it does access the DVD for a few seconds but then nothing). 

I have another 160 GB "regular" hard disk here as well and when I install that I also get the choice to boot from the hard disk or the DVD (although booting from the hard disk does not work since it's a hard disk from a PC). 

combination of Macbook and SSD, installing into the hard drive bay?  I've seen many posts from people who have had success putting an SSD into their Macbook so I am assuiming it's possible. 

Some more information about the Macbook:

Boot ROM Version: MB41.00C1.B00

SMC Version: 1.31f1 

Info:
MacBook, Mac OS X (10.6.8)

MacBook Pro :: Can't Boot Past Grey Screen

May 26, 2012

I was having trouble submitting an assignment on the American Military University website. After I finally submitted and verified my submission was successful, Finder popped open a window, without being prompted, with a specific part of my "private" folder showing. In the info window it showed that I had read only privleges, but that a user named "wheel" had permissions. Thing is, there is no such user. I am the sole user, and that is not my user name. I panicked, thinking I was being hacked, and moved the entire "private" folder to the trash. It was over 5 gigs. I had to input my admin password after dropping the folder in the trash. Then, my system froze. Now I can't get past the grey boot screen with apple logo and spinning wheel.

I've tried zapping PRAM. I ran disk utility from both the install disk and the startup disk for live verify. NO errors found. Still won't boot. I tried safe mode, and got a status bar below the apple logo but it vanished before filling completely and then the MacBook just continued to hang there spinning the wheel without a status bar. Tried rebooting while holding shift-command-v and got to watch as the computer tried to boot in safe mode, but I got the following messages before the darn thing just began to hang there again: 

getaddrlinfo(): node name nor username provided, or not known
getaddrlinfo(): node name nor username provided, or not known

May 28, 2012

Today I was using my MacBook 2008 aluminum, and I ran out of battery so the system shut down the computer to save the files. I plugged in my computer to start it up but the screen turned grey for a while. I shut down my computer and turned it on and it started up to the grey login screen but it won't let me boot passed it. I have tried to get passed it in safemode but it did not work. I have tried to repair my hard drive and my permissions and reinstall osx lion but it didnt work.

MacBook Pro :: Stuck At Grey Boot Screen

Jun 29, 2012

So yesterday i turned my laptop on to find out it wasnt booting up past the grey screen. Later on i did some trouble shooting and finally got it past to the main desktop screen. Now, recently i had just uninstalled and deleted my Windows 7 Pro partition i had put onto my laptop a while back but when doing so, when i tried getting my hard drive back to full storage amount by deleting the partition,it gave me some error. I believe i figured out the error and was able to use my laptop from then. Once my computer was letting me get to the desktop screen, once i would click on an app it would often give me the pin wheel and stop me from clicking on anything else for a good minute.

Today,i had backed everything up and thought that i would just reformat and re install OSX to remedy the whole issue. This was not acheived. I had been able to get to the desktop screen a few times but still got the pin wheel situation going on. A couple tries later im stuck here at my grey boot screen. No Apple sign showing up, just stuck. Im usually a very computer savey person but this is kind of just making me wonder. I ordered a new hard drive (which i was going to upgrade anyways)but wanted to know if this even could possibly be the issue. I upgraded from my stock hard drive about 6 months after i had gotten my laptop (mid 2009 model). The last 3 years ive been traveling very often, flying frequently and using it often for playing my DJ gigs. Im wondering if alltitude and hot clubs could take a tole on a hard drive when its running hot?

OS X :: System Running Very Slow / Hangs At Gray Screen Ion Startup

Jan 29, 2010

Macbook Air, Rev A. Worked like a charm for 1.5 years.Upgraded to a Rev c SSD and gave the Rev A to the wife.She installed NOTHING.Within a few weeks it started running VERY slow. I'm talking 2 minutes of beach ball per click.I use Disk Utility to check the drive. No problems of any kind.

Rebooting would take -- and I'm not exaggerating -- over an hour. First it would sit with a grey screen for 5 minutes. Then with an apple logo for 10 more. Then with the little spinning circle for 30. Then the desktop background would show up and sit for 20 minutes, etc.

Was gonna upgrade to Snow Leopard so what the heck, backed it all up and installed Snow Leopard. To my surprise, it instaled Snow Leopard on top of the old OS -- it kept all the files around so no need to restore from backup.

Speed problem SOLVED!Then a few weeks later the same problems.This time I check the drive AND run the hardware test. No problems.I ERASED the entire drive. I installed Snow Leopard.All is good for a few weeks.Then the problem came back a 3rd time.

I go to reinstall a 3rd time and Snow Leopard doesn't even acknowledge that there's a hard drive in the machine! And when I look in system profiler it says there's no drive of any sort. Yet it will reboot and run... just VERRRRRYYYY slowly.

I'm ready to replace the drive with a Runcore SSD or some such other device but I want to be sure the problem is the drive and not some other aspect of the hardware (motherboard, RAM, etc.)Anyone ever seen this? Anyone have any ideas as to how to investigate, solve, conquer, save myself from madness??

OS X :: Apple Logo Not Appearing At Grey Boot Screen?

Jan 25, 2010

Sometimes, when I turn on my iMac (10.6.2), the system will not load, you can see the grey screen but empty, no apple logo there. I have to force a shutdown pressing the power button and when I turn it on for the second time it will work properly.

It only happens once in a while but I cannot understand why, since nothing changes.

PS.- I have verified my disk with the disk utility and everything seems fine.

OS X :: IMac Won't Boot - Apple Logo And Lingering Grey Screen

Oct 30, 2008

I had been using my iMac all night, when all of a sudden the bouncing beach ball appeared and everything became unresponsive, apart from the mouse cursor itself. It might be worth noting that a few hours prior to this, I plugged in an external hard drive to burn off a DVD. This external hard drive has two partitions, the first being a restored image of Leopard; and the second, my out of date backup ("yes, I know").

I subsequently restarted my machine, enjoyed the chime, pondered the excessively long start up and looked bemused at the Leopard Setup wizard. I realised that the restored Leopard partition had booted up instead of the internal disc. So, I unplugged the external drive, pressed reset on the iMac and was immediately greeted first by the reassuring chime, then by the Apple logo and a lingering grey screen and finally by a flashing dark folder icon with a question mark in the centre for eternity.

I tried rebooting a few more times. Same. I've been frantically Googling but only found the PRAM reset and a very frightening iMac disassembly guide. I've tried plugging the external drive back it, but it refuses to boot Leopard from that now. What can I do? I feel so helpless on a Mac, on a PC I'd at least be able to open the sucker up before panicking! I've been working on a client's flash web dev project for months, and not made a back up in about half that time. The website is supposed to be going live tomorrow! Luckily I have the site uploaded, but the entire source code is potentially lost, so in the long term this is a major catastrophe!

OS X :: Macbook Doesn't Boot - Blank Grey Screen, CDs Not Recognised

Nov 24, 2008

My Macbook will not boot up. I am now faced with a plain grey screen with no apple logo, chime sound or activity wheel appearing.

Like most Macbook users I know, I rarely go through the booting up process from day to day use unless the System Updater requires a restart, but this time there was a different reason for me restarting the system.

When I was expanding an archive with Stuffit Expander, the app froze up. I went and deleted the archive file knowing that it was corrupt, but I did this too soon before the app had a chance to close down properly. It became stuck as a process that couldn't be closed down. Its dock icon didn't have a 'Force Quit' menu option so, I chose to perform a restart.

The Macbook went through the startup process but took a very long time. (I guess after reading around the forums this was fsck attempting to scan and repair the potentially damaged hard drive). I mistakenly performed a hard reboot thinking the system had hung.

The second time, it displayed the apple logo and wheel for about 2 minutes before showing a circle with a line through it and no further activity. When I rebooted again the apple logo and wheel were displayed with the hard drive activity audibly in a repetitive on and off state. I left this for about 15 minutes before deciding to turn it off. At the present moment it starts up to a plain grey screen as mentioned at the beginning. I tried experimenting with removing the extra 2gb memory module but there was no difference with or without it. I tried resting the NVRAM with Option-Command-P-R but all I got back was the startup chime (i.e. the muted volume I had it at has now reset to the default level).

When Option is held down on booting, the mouse cursor is visible over the same blank grey screen. No volumes show up. I have selected the Finder Preferences option to hide all volumes from showing up on the desktop, but I doubt this would affect volumes from showing up on the boot up screen.

I have tried booting from the 10.4 CD that came with the Macbook and the 10.5 (retail) DVD. The 'C' or 'D' keys do not have any effect either.

I think my options now are either to try and obtain a firmware reset CD which might make it possible to recognise volumes again, or there's the possibility that I'll have to get a new hard drive. Can you suggest anything else I might be able to try?

On the subject of hard drives, if it turns out that the Macbook's hard drive is beyond repair and I need a new drive I only have a caddy for 3.5" PATA drives which I use for Time Machine. With an appropriate 2.5" SATA caddy is there any way I could access the filesystem in Windows? How else could I format the drive to the correct FS?
