OS X :: When I Start Computer, Grey Screen Comes Up With The Apple Logo

Nov 10, 2009

When i start the computer and the grey screen comes up with the apple logo etc., a grey "loading" bar has started appearing in the bottom of the screen. Takes a few minutes for it to go away. In the meantime the computer gets very hot and the fans are up to 6000 rpm. Then the os starts up, and I cannot download anything, due to the fact that it thinks my harddrive is full, though i have more than 100 gb of free space.I cant even download the 10.6.2 now due to the harddrive appears to be full

OS X :: Getting Kernel Panic After Logo Screen

May 24, 2010

My 3+ year old MacBook is unable to startup anymore. Whenever I boot up, after the apple logo I get the Kernel Panic. This happened after one time when I forced shutdown after I thought my macbook crashed. I've read from past threads this is possibly to do with hardware problems, but I can still boot to bootcamp windows (which I am currently using) and all seems to work fine. What can I do?

MacBook Pro :: Kernel Panic Grey Screen?

Aug 28, 2014

i have a Macbook running mountain lion, which froze today on safari.  I had to force close then when I restarted, it stuck on the grey screen with apple logo and pinwheel.  I tried rebooting in safe mode, which eventually came up with the following    

panic(cpu 0 caller 0x004384FF): "unable to find driver for this platform: "ACPI".
"@/SourceCache/xnu/xnu-1228.12.14/iokit/Kernel/IOPlatformExpert.cpp: 1407  

and a lot of other stuff under that.  I understand this is a kernel panic?  

i've tried a disk repair which came back as 'disk utility can't repair this disk etc'  

is there any hope I will be able to connect via Ethernet to another mac and get to my hard drive or is all hope lost?

MacBook Pro

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.

IMac :: Tried To Re Switch On - Grey Screen Came Up, Apple Logo?

Aug 16, 2010

Hoping someone can help - my imac (approx 15-18 months old , intel) won't start.

Last night on shutting down DPP (canon Digital image software) was hanging and system asked me if I wanted to force quit it...sadly I had switched off my bluetooth mouse and , as usually once mouse turned off switching it back on it never re connects - why did I buy the bletooth mouse and keyboard ?, so I could not confirm yes force quit - is there no way of selecting with keyboard like there is in windows ?

So I switched off at power switch. Tried to re switch on - grey screen came up, apple logo, the little timer circle but after a while timer circle stopped and nothing further happened.

have tried several more times and now don't even get timer.

MacBook Pro :: It Stuck On Grey Screen With Apple Logo

May 1, 2012

Macbook Pro was purchased in mid-late 2009 and is running on OS X 10.6. Today is suddenly stopped responding and so I turned it off. When I turned it back on it opend to the grey screen with the Apple logo and the loading icon and that is where it stayed. I have been searching for the answer on different forums but have yet to find a solution. My hard drive is appearing in the Disk Utility but not in the box when I try to reinstall OS X.

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!

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.

MacBook Pro with Retina display, OS X Mountain Lion (10.8.2)

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).

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?

Software :: Hard Disk Doesn't Get Further Than Grey Screen With Apple Logo?

Nov 8, 2009

OSX 10.4.11 (Tiger) PPC G4 733 MHz

My Tiger volume gets stuck when starting up, it doesn't get further then the grey screen with the Apple logo. The clock with stripes keeps working but it doesn't get me to the blue screen.

For compatibility reasons concerning different softwares i use (Protools, Reason etc...) i keep changing the internal HD's for years now, thus changing the OS's (10.3.9, 10.4.11 etc). Never caused any problem.

When i boot from another 'master' volume (f.e. 10.3.9) OR from the OSX install CD, putting the Tiger volume as 'slave', in order to verify its disk permissions or the disk itself to be able to repair them, it's 'invisible', not 'seen' by the other volume.

So no 'verify disk permissions' nor Combo Update possible, maybe those things could solve my problem.

My cables are working perfectly: making the exact same connections and jumper settings with all my other volumes, is no problem at all: every volume is correctly seen by the others.

Also, there is no USB or external firewire device connected while trying to start up.

Remark: never had any problem with this Tiger volume, starting problem only occured yesterday AFTER installing Toast Titanium (which worked normally), shutting down and trying to start up again.

Nevertheless, some minor problems occured beforehand these last days: some apps didn't work anymore, like Safari, itunes, installer and UnrarX. But i don't know if it's linked.

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.

OS X :: Kernal Panic After Installing SL

Sep 4, 2009

Over the last week I've had 2 of what I have now discovered are called "kernal panics". I've had this SR 2.2 for about a year and a half. I had one prior to installing SL last week 1 this week after installing SL. Other than the "You must restart your computer" message following the crash I've not noticed any other problems. I have not installed any RAM or other hardware. I've pasted the kernal panic report with the hope that someone might be able to help decipher what it means and what the issue might be.

OS X :: Can't Reinstall Tiger / Kernal Panic

Feb 8, 2009

I've written recently about my kernal panics on my imac g5 I reinstalled the original software and moved on to Tiger and it says "cannot install this on this computer" I have installed it before, it is my software bought free and clear. I don't know what to do. My son's college papers are due and we cannot get on the sites because our flash/etc. is not updated. I am now at 10.3.9 (I go to "about this mac", more info, and my system overview app will bounce on my tool bar and not come up.) I dont know what's going on. My hardware tests all came out clean.

Mac Pro :: Can Anyone Decipher Kernal Panic Report

Apr 25, 2012

I'm having them 2 to 3 times per day. In my limited research, I know it can be related to memory and I am in the process of pulling out pair by pair to isolate which one may be causing it, but no luck as of yet. Or is it related to something in the operating system. Below is the kernal panic report. [code]
