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
Here are my specs:
Core 2 duo
ATI Radeon HD 2600 pro
4gb ramÂ

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.

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.

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:

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.

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

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
