Screen turning grey and demanding restart

This may have been covered already, and my apologies if so, but I'm in the middle of a project and a google search turned up nothing. Every so often - and it seems to only happen when I'm using Safari - the screen will turn grey (from top to bottom) and a multi-language box will tell me I need to restart by holding down the power button and then starting up again. There is no way out of this, and it destroys whatever I'm working on. This may only happen once every few weeks, but I'd like to change that to never. What is the reason for this, and how can I fix it? It's a newer MacBookPro, 10.6. Thanks for your time and attention.

That's a *kernel panic.*
They are usually caused by hardware problems, but can be software, especially kernel extensions.
Start with this Apple article: [If “You need to restart your computer” appears|http://docs.info.apple.com/article.html?path=Mac/10.6/en/8965.html].

Update 10.1 to 10.4X and screen turned grey and enlarged?

Help. I update to OS10.4.3 from 10.1 and the screen turned grey and unclear and all icons are much larger. Tried system preferences but display only gives me the option of 640X480 and no other options. Went to universal acess and set to black on white, no grey, zoom off. In universal acess the screen is too large so I don't know if there is a button on the bottom I can't get to. I also tried a different monitor but the picture is the same. Turned off extensions on restart and reloaded OS again but no change.
I'd appreciate any help at all!

Hi Dr.P,
unfortunately Tiger does not support a direct upgrade from 10.1.x to 10.4.x. Although there are one or two anecdotical reports of successfull upgrades the vaste majority of users who tried this reported major problems.
There are 2 possibilities to get from 10.1.x to 10.4.x:
1. Perform and Erase&Install: Make sure you have a complete backup since the Erase&Install will completely wipe your hard disk!
2. Get a cheap copy of 10.2.x or 10.3.x, upgrade to this and then upgrade to 10.4.x
Personally I would choose option 1.
In case you choose the second option I suggest you follow this procedure for the upgrade to 10.4.x: 10.4 Tiger Upgrade: Decision tree+Checklist.
In any case, make sure you have the retail full instaall version of Tiger. You cannot use hardwware specific disks that shipped with another computer!

My computer suddenly refuse to start. When I turn it on it gives the startup sound but the screen is grey and after a while a little folder icon with a question mark inside turns up. It doesn't blink. What to do? Nothing happens if I try to start up from

As I say my computer, a mac mini refuse to start. When I turn it on it gives the startup sound and the screen turns grey and stay that way for a long time. And in the end a small folder icon with a question mark inside (it doesn't blink) turns up in the middle of the screen.
I have tried to start up from the installation CD holding down the C key on the keyboard. Same result. I have tried different key combinations while starting up. No result or rather same result. Nothing. Is the computer suddenly dead?
I was about to buy a new computer but I need access to my data on this one (I write this on an iPad) but hven't yet found a way.
Anybody have any good advice?
I thought it was a software problem, that the computer couldn't find the startup software or something and maybe it is, but I am beginning to fear that it could be a hardware problem.

You need to re install OSX. If you have the dmg file downloaded via torrentz this is how you can create a bootable external HD or Flash drive (8 GB+)

When i open my computer I get the white screen with apple symbol and there are vertical lines all over the screen with green pixels and after a few minutes the screen gets grey and I get message to restart my computer what happens

3 years ago I bought an IMac Desktop that I am using for a lot of things but the most important for dvd montage in Imovies and Idvd.
Now today when I opened my computer I get as usual the white screen with the Apple symbol but there were all over the screen vertical lines with green pixels and after a while the screen gets grey and I get message to restart my computer using the power button or the restart button and when I do so each time the same is happening somebody can tell me what is happening and what caused this. This computer is my work and now I have no income anymore.
On the Apple support site they are asking to enter the serial number and when I do so I get message it is wrong but it is the only one I have and I buy this computer in Cairo Egypt. I am living in Hurghada in Egypt for the moment. When I call the technical support of the shop where I buy it they are telling me that it is the hard disk or ram and that I probably lost everything on it and they are asking a big amount to repair.
Can somebody advise me on this matter. Thanks in advance

You can find the serial number either in About this Mc in the Menu bar under the , or it should be on a sticker under the foot of the machine.
If you have the install discs, try booting from them, holding down the c key and then using Disk Utility to check the drive.
You can also boot into Safe mode
To start up into Safe Mode (to "Safe Boot"), do this:
   1. Be sure the computer is shut down.
   2. Press the power button.
   3. Immediately after you hear the startup tone, press and hold the Shift key.
      Tip: The Shift key should be held as soon as possible after the startup tone but not before.
   4. Release the Shift key when you see the gray Apple and progress indicator (looks like a spinning gear).
During the startup in Mac OS X 10.2 through 10.3.9, you will see "Safe Boot" on the Mac OS X startup screen.
During the startup in Mac OS X 10.4 or later, you will see "Safe Boot" on the login window, which appears even if you normally log in automatically.
Please post back with results,
To leave Safe Mode in any version of Mac OS X, restart the computer normally, without holding any keys during startup.

Mail Folder turned grey and emails have disappeared!

I’ve got a problem with a folder in mail 2.1.3 whereby the folder (which contained a number of subfolders, each in turn containing a fair few emails) has turned grey and the emails seem to have disappeared.
All I did was to try and rename the main folder, but got a message saying the folder could not be renamed, and instead a new folder was created. This was when the original folder turned grey?? The dub folder structure remained intact but all the messages from all the folders have disappeared.
I’ve looked at what should be the folder contents in user/username/library/mail/mailboxes/THEFOLDER and can see that the subfolders and the messages are there but they simply dont show up in mail.
Can anyone tell me how to reinstate the messages in the folders, and maybe why this has happened?
Thanks in advance.
Phil

Perhaps we just lost the custom icon for that folder, you can navigate to it in the Finder, do a Get info on it and change the icon if you wish.
What is the best way to see if there is a potential problem with the disk?
We secretly did one wth the Safe Boot already, 1st thing it does is check & try to repair the disk.
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."
I consider DiskWarrior from Alsoft the best tool for disks, get the CD/DVD...

When I get to the login page on my macbook, I type in my password and it starts to load, but then the screen turns blue and it goes back to the login.

When I get to the login page on my macbook, I type in my password and it starts to load, but then the screen turns blue and it goes back to the login.
Iv tryed this numerious times still keeps going back to pasword. Can not get any further. Tried restart holding shift key.. still nothing. What do i do?

Thank you for your help.
I couldnt get to the hard drive/ desktop. Soft login not even working. So i could not do any of that.
In the end i took it to Apple and its actually the hard drive on its way out. A common issue with that series of Mac. Funny seeing i dont use this mac much. However being 2.5 years old and out of warrently, Apple have recognise this issue with this series/ Model and installing a new hard drive at no cost.
Very luck and greatful. And not feeling so dumb that it was something i did or could troubleshoot myself.
Hope this helps others that it just might be your hard drive failing.

When I type in my password into the login screen I get the rainbow pinwheel and then the screen turns gray and goes back to account selection... How do I access my account?

Today I was doing my chemistry homework when all of a sudden my mid 2011 MacBook pro running Lion 10.7.4 started going very very VERY slowly to a point where it was unusable. I restarted my computer and went to type in my password. When I did this, the computer recognized the password and began to boot yet the pinwheel came on and the screen turned gray and went back to the account selection screen. It continues to do this everytime I enter my password and I can no longer access my account. How do I fix this.

You can take some of the steps here, #4, #5 or even trying a #18
Step by Step to fix your Mac
but I suspect your going to first have to create a data recovery drive
Create a data recovery, undelete boot drive
to get your data off the machine,
then do a #20 to eliminate the bad sectors as that's why your getting the "pinwheel" it's getting a delay reading from the drive, right when your trying to log in too, what a bad spot for it to happen.

Why does my macbook pro 13'' mid 2010 screen turns gray and freezes while connected to external monitor?

Every once in a while my macbook pro just randomly instantaneously freezes and the screen turns gray and it has only done it while connected to a high res 22'' Dell external monitor (so far). Usually when this happens I'm listening to music and I noticed my music continues to play but the keyboard is totally unresponsive forcing me to manually press the start button until the computer force shut's down. Luckily I havnt lost anything yet but I hate having to restart my macbook pro that way...just want to know if its a glitch in the software or if I have a more serious hardware problem. This problem has occured maybe 4 times since I got my macbook last summer 2010 so its not too bad, im just worried cause these computers aint cheap.

Duquan,
Macs can be picky about the RAM which they use; the “Your computer restarted because of a problem” message typically indicates a RAM problem. Since you have a Mid 2009 model, it should have 1066 MHz RAM installed rather than 1333 MHz RAM. If your RAM was mislabeled, then that might cast some doubt upon the quality control which that RAM manufacturer uses. My suggestion would be to purchase 1066 MHz RAM from a reputable manufacturer.

If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time after you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V). Please include the BOOT_TIME message at the end of the log extract.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post any other kind of report — it will be very long and not helpful.

Screen turned black and makes some sort of an alarm sound

Does anyone knows a solutions for this: my intel iMac was on all afternoon till suddenly the screen turns black and it starts making some sort of an alarm sound "tuut tuuut". I tried restarting but nothing changes. I tried restarting from the installation Disc with C-key but no result. As a matter of fact i can't even get the disc out of my iMac anymore. Thanx

That sounds like hardware problems, I suggest you call your local Apple Store to my an appointment for them to check it out for you.

Screen turns dark and freezes, when refreshing deletes written txt

Firefox should be more compatible without blaming others.
While writing this same note, or an email or text, suddenly the screen turns dark and freezes, impeding to edit or recover the work. When clicking Control Shift R , screen/server refreshes and work lost.
Kindly assist and solve this issue. I uninstall and reinstall with no avail, problem persists.

It's disturbing that you get ads just starting up the browser. Where did you download Firefox from? Unfortunately there are some unauthorized modified versions promoted in search engine results...
Some things to check:
# Home page -- [[Startup, home page and download settings]]
# Extensions (more detail below)
# Malware -- [[Troubleshoot Firefox issues caused by malware]]
# Program shortcut (more detail below)
'''''Extensions'''''
Add-ons, and particularly extensions, can override your settings in Firefox's normal dialogs. Use the Add-ons page to review and disable or remove ALL nonessential or unrecognized extensions. Either:
* Ctrl+Shift+a
* orange Firefox button (or Tools menu) > Add-ons
In the left column, click Extensions. Then, if in doubt, disable.
Usually a link will appear above a disabled extension to restart Firefox. You can complete your work on the add-ons page and click the link as the last step.
'''''Program Shortcut'''''
Not sure exactly how you do this on Windows 8.1, but on earlier versions:
right-click the shortcut you use to start Firefox > Properties > Shortcut tab
Check the "Target" line and make sure there is no URL at the end. By default, the target ends with
firefox.exe"
with no URL after it.
