MacBook Pro :: 13.3 - Screen Goes Gray - Restart System

Mar 23, 2010

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.

MacBook Pro :: Getting Blue / Black Or Gray Screen And Force Shutdown

Aug 29, 2014

Macbook Pro 15 inch

OS X 10.9.4

2.4 GHz Intel Cor i7

4 GB 1333 MHz DDR3 

I have had my macbook pro for just over 2 years. About a week ago it started randomly giving me a blue striped, grey, or black screen. The fan pins up and won't stop and either the laptop shuts itself off or I have to force it off. When it restarts it is very slow and sometimes the fan kicks on and won't stop and the screen just stays white after the initial apple and spinning wheel screen, so I have force shut it down and try again. Other times it eventually loads and lets me in but everything responds slowly and takes some time to open.

Info:
MacBook Pro, OS X Mavericks (10.9.4)

Im selling my macbook pro and am trying to restore it to factory settings. I have inserted the "install disc" many times. However, my laptop is never able to start up.

I've tried clicking restart when it instructs me to...that didnt work I've tried going to system preferences --> startup disk --> clicking the install drive and it still didnt work. What can I do? My mac can start up and work perfectly fine without the disk, its just that i need to restore it to factory settings.

Mac Pro :: Get A Matte Gray Screen On Restart, OS 10.7.3

Mar 15, 2012

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.

OS X :: Screen Goes Gray & Message Tells To Restart

Jun 19, 2007

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.

MacBook Pro :: Won't Restart/shutdown Black Screen & No Keyboard Backlight

Mar 30, 2012

My 2009 MBP would have problems shutting down or restarting. On a shutdown, it would appear to off, black screen and no lights, but if you tried pressing the power button nothing happened. I had to hold the power button to turn it completely, then press it again to startup.Restarts had the same behaviour, it would get to a black screen and I would have to hold the power button and then press it again to startup.I ended up taking this MBP back for another problem, and they replaced it with a 2011 MBP (since I had recurring logic board that failed a few times).Anyway, I swapped the SSD from my old mac into the new one, and I have the exact same behaviour!!Seems to be some corrupt settings or something. So I booted from a Mac installation disc, wiped my hard drive and reinstalled the OS, then I restored from Time Machine, and unticked the option to restore settings.I want to also add, that my backlit keyboard isn't working either.I tried resetting the SMC, but the power light on my charger didn't cycle orange/green, so I'm not sure if it worked. I tried multiple time, following Apple instructions.I also reset the PRAM, which did work.

MacBook Air :: Stuck On Black Screen With Movable Cursor But No Able To Shut Down Or Restart

Dec 2, 2014

I accidentally connected my wife's MacBook Air to my docking station at work today. Nothing seemed to happen so I undocked it and the computer displayed a black screen and I could see and move the cursor using the trackpad. I then tried shutting down by holding the power button for 5 seconds, 10 seconds, 1 min, etc. Nothing worked and it's stuck on the black screen so I can't use Yosemite's menu to shut down or restart. When I leave the computer idle for around a minute, the cursor disappears but it will reappear after pressing keys on the keyboard.

MacBook Air, OS X Yosemite (10.10.1)

OS X V10.7 Lion :: Gray Screen After Restart - Permission Errors In Disk Utility

May 10, 2012

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.

Desktops :: Mac Pro Goes To A Black Screen When Idle And Won't Restart?

Jun 20, 2009

Recently my Mac Pro has been going to a black screen when idle for a while and I need to power off using the power button and restart. It's not set to ever go to sleep but if I use the sleep function under the Apple, it functions as it should, waking when I touch a key (although I don't let it sit for a while before I wake it). When it is in the black screen mode, it still is performing Time Machine backups.

PowerPC :: IBook G4 - Blue Screen With Black Box Asking To Restart Computer

Feb 8, 2009

Everytime I turn it on I get a black box asking to shut down or restart the mac. I have managed to get it to turn on to powersave and managed to update the software. Thought it might help but just made it worse - it won't boot up at all now past an apple symbol with a little swirly thingy underneath (I apologise now for my lack of intelligence when it comes to computers/knowledge/names of things!) The first time I managed to boot the computer up it came up with the grey screen and a little folder flashing between a face and a question mark which I assume meant it couldn't find anything but that appears to have gone away now. I bought this computer new from Apple about 2 - 3 years ago and no disks were provided with it.

OS X :: Gray Screen After Restart Between Disc 1 And Disc 2?

May 24, 2009

So last night, my Macbook started to show a folder icon with a question mark on it when I tried to boot it up. I tried to restart a couple different ways, using the Install disc, and when nothing worked, decided to reinstall OS X entirely.

Well, after the first disk finished installing, it said to restart the computer and be prepared with disc 2. Unfortunately, after the restart, I just get a blank gray screen, while my optical drive makes short repetitive noises.

Any advice on how to get the reinstall to work right?

MacBook :: Screen Pops Open Like It Is Spring Loaded?

Dec 23, 2009

I took my laptop in yesterday because there was dust inside the screen and they replaced the whole screen and top. However, it now pops open when I pick it up. I'm a student, so it gets carried all over the place in my backpack and I can't have it popping open all the time. It's not upside down or anything, its just when I pick it up. I am leaving to go back to school in a week and I can't drive the 1.5 hours back to the mall again. What can I do? Duct tape?

Also, if I have a campus authorized retailer, can they do repairs?
