Intel Mac :: It Won't Start Up Past Grey Screen , Apple And Spinning Clock

Apr 9, 2012

I have an intel imac - can't tell you much about the details as I can't get any info out of it. I installed snow leopard about a year ago - no issue since then other than occassionally the screen goes black but nothing major.Yesterday, I backed up to my usual passport backup and then today, it froze. I couldn't turn it off or restart at all so resorted to the power button. Since then, I can turn it on, it goes to the grey screen (no blue screen) and I get the apple logo and the spinning clock/wheel. For hours and hours....So, I tried one of the apple support pages and worked through - peripherals, safe boot, NVRAM, PRAM, tried to reboot with mac osx disc (the original not snow leopard) - nothing. Absolutely nothing changes - same old grey screen, apple logo and spinning clock/wheel.

Sep 10, 2014

New iMac is stuck on grey apple screen after startup. It is a 3.4GHz Quad-core Intel Core i5 running OS 10.9.4. The problem occurred after a migration from my older 2009 iMac which is running Snow Leopard 10.6.6. When the restart occurred from Migration Assistant, the new computer will not boot up to the login screen. Disk utility did not solve problem.

IMac :: Intel-Based Unable To Power On - How To Fix It

Apr 19, 2009

I have a 17 Inch Intel-based IMac (2006). when I press the power button I can here and feel fans running but the Power Indicator Light turns on and the screen remains black. Nothing else happens. Not sure what I did. I didn't take anything apart. I checked over the whole compartment and all connectors appear to still be connected.

I did some research figured out how to disassemble the IMac, purchased a new hard drive, backed up the computer and when I took it all apart there was a third connector on the hard drive (temp sensor?). The new drive did not have this connector so instead of experimenting I put the computer all back together.

MacBook Pro :: Won't Go Past The Grey Screen

Apr 25, 2012

Okay well, to start off, I got my MacBook from a distant family member who got a new one so they let me have their old one. They got it from a pawn shop so I don't have the disk that we got the OS from but it hasn't had any issues UNTIL NOW. I need to use my laptop for a homework assignment. Everytime I turn it on it'll just stay on the loading screen, I left it for 4 hours yesterday and it still wouldn't work. I reset the (insert acronym here) thing already, the thing where you press control, option, P, R keys at start up. because my assignment is on the laptop and it's due tomorrow.

MacBook :: It Won't Get Past Grey Screen

May 25, 2012

My Macbook Pro (2008) was upgraded to Lion 10.7.2 before I bought it used. It's always been slow and after a little while it won't boot up properly, it only gets as far as the apple logo with the spinning wheel underneath.

I've have used Recovery HD and Disk Utility to repair/verify the hard drive and after the repair it still won't boot up past the apple logo. I downloaded OSX Lion 10.7.4 (client combo) update onto an external drive but I can't install the update when using Recovery HD. I've tried mounting the existing hard drive onto an external drive, but I get an error mesage immediately.

There are only a few folders I need to take from the existing hard drive in the Macbook Pro. What can I do to either access my hard drive or get it to boot up properly? I have a retail copy of a Snow Leopard DVD that I can use. I believe I might have saved Lion onto a DVD a while ago, but Apple seems to insist we intall by downloading the latest Lion? Basically I need to access the hard drive without erasing the data.

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

MacBook :: Won't Get Past The Grey Start Up Screen

May 24, 2012

I purchased my Macbook in 2008, roughly July.

My fiance unknowingly shut down my macbook in the middle of start up. Before that it was running perfectly fine, I had no issues. After my fiance stopped the start up, the macbook won't turn on. It'll load up to the grey loading screen (example here)... It doesn't make much noise as it starts up either. I have all original discs that came with the macbook, if that helps any.

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

MacBook Pro :: Cannot Even Startup Past Grey Screen

May 30, 2012

I sure hope your day is faring better than mine...To try and make my new issue easier to follow and to save face as I feel like an idiot, permit me to explain in bullet format:

First things first: I was running 10.6.8 SL on my 2006/7 model MacBook pro 15.4 w 2 gig sdram, right now I'm running nothing. When I turn on Mac it goes to grey screen and I see a folder/?/apple symbols rapidly interchanging on screen. This occurred after trying to use TM for my first time as I deleted some items I shouldn't have. In time machine all seemed kosher until the first attempt said not enough space on hd so I decided to only click on sys folder in TM. this was where prefs and files were accidentally deleted from after all. The kicker is my Mac still functioned I just noticed my HD no longer had a name, and a few other issues were happening, but I could access and open files, go online, etc... Post time machine none of that was possible! I tried first putting SL disk in but wouldn't read it, so tried restarting w disk in drive. HUGE ERROR on my part. This is where the grey screen desc above took its place. I looked on iPhone and have followed all available suggestions but have come to realize at some point I must have in error created a firmware Pw. I tried entering it but the lock simply stays put (when I attempted one of many fixes to my problem listed online). So now I'm left not knowing if whatever happened messed w my firmware pw or if I somehow chose something diff as pw but I highly doubt that. In any case, I have all of my life locked into a useless box now and I had thought this is why I bought external and used time machine. I've come to loathe TM. it's not as simple as I had thought otherwise none of this dshould have occurred. Does anyone have any ideas as to how I reset or altogether delete firmware pw, and best way to reinstall.

PowerPC :: Power Mac G5 Will Not Get Past Grey Apple Screen

Jul 15, 2009

When I turn on my computer, the wheel keeps spinning and stops on the grey apple screen. If I leave it there for a few minutes, the fan gets really loud.

I tried pressing Apple, Option, P, R, but it only chimes once.

I also tried holding down shift and restarting.

And I tried holding down option and restarting.

I even tried to take out the memory and put it back in.

Nothing is working.

I have the startup disks, but I don't know how to put them in the cd drive.

Since the computer won't boot up, I can't open the tray.

MacBook Pro :: 2007 Won't Get Past Grey Loading Screen?

Mar 23, 2012

I had been using my MBP running Snow Leopard to play movies and music through a TV/stereo and brought it with me when I moved to do the same, but now it won't start it.  I kept it asleep as I brought it on the plane, then when I got to my new apartment, it was frozen.  I shut it down, then tried to turn it back on but it get stuck in the grey loading screen with the Apple logo. 

I've tried starting in safe mode (it will bring up the safe mode loading bar, then that disappears and it gets stuck on the normal gray loading screen).I've also tried resetting the SMC and NVRAM. 

Then, I tried to start it up from a friend's OS X install disk (but it came with his MacBook from the same era, so idk if it only works for MB and not MBP), but that doesn't work either (selected it as the startup disk by holding Option when booting up, then selecting it.  It then goes to what it does normally except it will turn itself off instead of gettting stuck.) 

I don't know what else to do.  I'm assuming something is seriously broken.  I'm hoping it might just need a reinstall or maybe a new hard drive, which I could do if it's not too expensive.

MacBook :: Retina Won't Boot Past Grey Screen With Logo?

Nov 30, 2014

My computer died last night with each application not responding. I couldn't shut down normally so I held the power button to turn it off. 

Next morning, I tried to boot the MacBook Pro and the boot process stalled at the grey screen with the Apple Logo and spinning wheel. I let it go for an hour and there was no change on the screen. Based on Apple's desk I ran Hardware diagnostics (extended with looping disabled) and got the following error 

4HDD/11/40000000: SATA (0,0)  

The screen shot is below 

I ran this again with standard testing (no looping) and standard with looping and all gave the same results.

OS X V10.6 Snow Leopard :: Kernel Panics On Startup - Won't Get Past Grey Screen?

Jun 21, 2012

So out of nowhere my unibody MBP (specs, etc below) locked up yesterday while I was watching a video using VLC.  It stopped responding to anything so I held down the power button until it turned off.  I waited about 10 minutes and turned it back on.  Grey screen with spinning cog showed up for about a minute and then kernel panic.  Held down power button until it turned off.  Tried repeatedly - same results.  Won't boot into Safe Mode - still get a kernel panic everytime.  It will let me boot the machine into Target Disk Mode.  It will boot from my Snow Leopard install disk where I ran Disk Utility and "repaired disk" and "repaired disk permissions" on both the drive and the volume.  All the "repair disk" and "repair disk permissions" ended with messages in green type saying that the disk/permissions appear to be OK. 

I have an external FW drive used for TM backups for the machine.  A fair amount of data has been added since the last TM backup (which was less than 30 days ago) that, ideally, I'd like to not lose by resorting to restoring from a TM backup.  It's not the end of the world if the last (roughly) 30 days of data/changes ends up being lost, but I'm willing to work on getting it back up and running without doing an erase and install and then restoring from a TM backup if at all possible. 

Definitely if any other information or data is needed from me in order for anyone to assist, please let me know what it is and I'll do my best to provide it.

Power Mac G5 :: MacBook Pro - Tiger Won't Boot Past Grey Apple Screen W/ Spinning Gear

I have a 1.83 Ghz MBP with 512 mb of RAM (lame I know). The other day someone was using my computer to burn a CD on iTunes when all of my programs began failing. On instinct I rebooted my computer to solve the problem. Alas, now I cant boot past the grey apple screen, and the gear is spinning away. Saddest part of the story is that I had time set aside to back up my computer the day after this happened . Anyway what is the best thing to do from here? I haven't made any moves to fix it yet really, so what is the best thing that I can do to try and get my files back?

IMac (Intel) :: Grey Smudge In The Middle Of Screen?

Nov 30, 2014

OS X Yosemite

iMac (21.5-inch, Mid 2011)

Processor 2.5 GHz Intel Core i5

Memory 4GB 1333 MHz DDR3

Startup Disk Macintosh HD

Graphics AMD Radeon HD 6750M 512 MB 

Not sure exactly when it started but I noticed it about half an hour ago and have come straight online to 'troubleshoot' the problem. The is a grey smudge/shadow in the middle of my screen and I am unable to remove it by cleaning the screen or restarting my computer. I have seen similar issues posted with no resolve so I don't know if people discovered a fix or just gave in and took the computer into the Apple store. With no way to transport the computer safely into the city centre, I would like to avoid doing that if at all possible.

OS X :: Grey Dim Screen Swipes All The Way / You Need To Restart Your Computer

May 10, 2008

So i updated to 10.5.7 the other day and it took a few restarts to get it going, but all is well now.

i was just tooling around on my computer with several programs open as i usually do (safari looking at gmail, ical, mail, itunes, ichat, weatherdock, TM error logger), then all of a sudden a grey dim starts at the top of the screen and swipes all the way to the bottom then the following message appears: "You need to restart your computer. Hold down the power button for several seconds or press the Restart button."

Anyone else have this issue with 10.5.7? what did it mean if you had it in the past?

I'm running a mid 2007 MBP 2.4 SR, with stock 2GB RAM, stock 160GB hard drive, 2 Western Digital external hard drives, one USB for Times Machine and a FW800 for iTunes media.
