OS X V10.6 Snow Leopard :: IMac Can't Update To 10.6.8, Get A Gray Screen On Restart?
May 20, 2012
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
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.
Had to force quit a number of applications to shut down computer, restarted it but froze on opening. Shut down with the power button and now it won't get past Gray screen with rotating dial (thingy)...tried the safe boot option but this seemed to get stuck after identifying some issues.
I click on the hd hard drive and change the settings to no one can read or write now I had problem to open the computer as soon I start it became gray screen so I re-stall the software and as soon I back up the computer is asking me the password I type it and can't enter after keep asking me the password is wrong
i changed the name of the hard-drive for other reasons, and i guess i must have somehow erased the two which show up in the login box. And, i cannot locate the disks.
Info: MacBook Pro, Other OS, no start up disk to be found
[URL] I can access via server admin but cannot log into the server from the login window at the server itself with the exact same admin credentials that I used through server admin.Â
D/Loaded Adobe 10.3.1, now all pdfs from internet are just a gray screen. Pdf's attached to emails OK. I'm on latest Safari Browser. Can't find earlier non-troublesome Adobe REader on Internet.

My computer displays grey screen and apple logo for 10 minutes or more during start up and shut down. Sometimes it refuses to shut down. This issues started after installing OS lion. What do I do?
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.
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.
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:

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 ...
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.......
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.
Ok I did some updateing and now get a black screen after booting. Here is what I did WAS running 10.5.8 Updated to 10.6 using a USB Downloaded and installed 10.6.3 Combination update (everything worked great) Installed iLife 2011 Downloaded latest update for iLife because is said I could not use it unless i updated.Â
Restarted fine logged in, showed display background. Then all black. Rebooted, black screen. Reboooted again, Black screen.Â
The issue only came up when I did the software update for iPhoto, iMovie,iWeb,iEverything else.. Â
I have a 3.06 intel core 2 duo with 4 gig ram and 500 gb free space. Backed up on time machine on seperate HDD still plugged in to USB. Since I don't have USB selected as a boot drive can I still boot from the install 10.6 USB?Â
