Blank gray screen on my macbook pro after rebooting!

After rebooting my macbook pro, after choosing english as the language, a blank gray screen appears and then again goes back to the choose language menu. what should I do?

Shut down your computer and disconnect all peripherals (keyboard & mouse if pertinent) from your computer. Now reboot.
If the Mac starts up normally, shut it down again and then plug in one of the peripherals (keyboard or mouse first) and start up your computer again. If it does so successfully repeat the process, adding one peripheral at a time until your Mac acts up. At that point, disconnect the last peripheral you added, reboot your Mac and search the peripheral vendor's website for an updated driver.
If no driver exists or the problem remain after installing the new driver, try a different cable or a different port on your Mac.
If none of the above works, again disconnect all peripherals from your Mac, hold down the "shift" key to start up in "Safe Boot" mode.
If the Mac starts up correctly, restart without pressing the "shift" key.
If your computer still does not start up properly, shut it down and restart it while holding down the Apple+Option-P-R keys; keep holding "all 4 keys" down until you hear the startup sound "twice."
If none of the above work Disconnect all peripherals from your computer. Boot from your install disc & run Repair Disk from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
Select your language.
Once on the desktop, select Utility in the menu bar.
Select Disk Utility.
Select the disk or volume in the list of disks and volumes, and then click First Aid.
Click Repair Disk.
(If Disk Utility cannot repair, you will need a stronger utility (3rd party) - Diskwarrior or Techtool PRO)
Restart your computer when done.
Repair permissions after you reach the desktop-http://docs.info.apple.com/article.html?artnum=25751 and restart your computer.
Remove any 3rd party ram.
Reinstall Snow Leopard - This will install a "fresh" copy of Snow Leopard without archiving old system files but leaves the rest of your files in place.
If your computer is still under warranty or you have Apple Care, take full advantage of it by letting tech support deal with your problems. It's what you're paying them for.
Out of warranty - take the computer to an Apple store or an AASP. Whichever is more convenient for you.
Mac OS X (10.6.7)
Have you considered updating to 10.6.8?

HELP!! Black screen on my MacBook Pro after leaving open and on for over 8 hours.

Hi everyone,
This is the first time I'm using the discussion board as I haven't had any problems with my MacBook Pro since I bought it in November 2010. However, yesterday, I left my laptop on and open for over 8 hours without realising. When I came back to my laptop it had a black screen that just wouldn't go away. I pressed all the buttons on my keypad to wake it up but this didn't work. The caps lock key lights up when pressed and the volume button makes the clicky noise when turned up and down but the screen is still black. I have tried turning the laptop on/off using the power button several times. When it starts up it makes the usual sounds and I can hear that it is on but the screen is still black.
I do not use my laptop for anything complicated. I really only use it to browse the web. I hope someone can help me. I have tried to make an appointment with the Genius Bar but there are no available appointments at my local one. I'm not a mac expert and don't understand technical words so please speak in layman terms otherwise I won't understand. Any help would be greatly appreciated. Many thanks

If you've a 15" version, maybe...
Mid-2010 15" MacBook Pros - the bad NVIDIA GPU
If you're having frequent kernel panics with your 15" mid-2010, or intermittent screen problems, the problem is, more than likely, the faulty NVIDIA GPU found in a number of those machines.
Here's just a sample of a kernel panic log that points to the faulty NVIDIA card:
Kernel Extensions in backtrace (with dependencies):
         com.apple.GeForce(6.4.0)@0x82ac4000->0x82b7afff
            dependency: com.apple.NVDAResman(6.4.0)@0x834a0000

            dependency: com.apple.iokit.IOGraphicsFamily(2.2.1)@0x8301b000
Here's the "official" Apple take on the issue - but the very real kernel panics need not be preceded by 'Intermittent black screen or loss of video'... in fact, you might not experience any video problems at all. Although video problems can certainly be a portent of things to come…
So what can you do? Print out a copy of your kernel panic and a copy of the Knowledge Base article and take them, along with your machine, to your local Apple Store or an Apple Authorized Service Provider. They should be more than willing to install a new logic board at no cost. I have no idea why this faulty GPU is making the headline here on the MacBook Pro forum so often now - could it be because Mountain Lion is just bringing the issue to a head more readily? I don't know - I only know that we're seeing more and more of these kernel panics of late.
Good luck,
Clinton

Jerricayoung,
you have a 13-inch Mid 2012 MacBook Pro. It’s modern enough that it supports booting into Recovery mode. To do so, hold down a Command key and the R key as you start up. It should eventually show a Mac OS X Utilities menu. Select Disk Utility from that menu; when the Disk Utility window appears, select the bootable volume from the left-hand side of the window. (It’s typically called “Macintosh HD”.) When the volume is selected, some buttons will appear on the right-hand side. If it’s not greyed out, press the Verify Disk button; if it is greyed out, or if it reports on errors that it found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu; that will restart your MacBook Pro in its normal mode. With luck, that will be enough to get you to your normal login screen, rather than the white screen.

Screen stuck on gray, used shift key and my screen appears with MacBook Pro and not the recovery option. Please help

Screen stuck on gray, used shift key and my screen appears with MacBook Pro and not the recovery option. Please help!

Hi ..
Shift key boots into Safe Mode, not Recovery.
This only works on a Mac running v10.7 Lion or later.
Startup your Mac while holding down the Command + R keys. From there you should be able to access the built in utilities to repair the startup disk and restore OS X using OS X Recovery
If you can't boot into Recovery Mode, help here > Mac OS X: Gray screen appears during startup

Mountain Lion install results in blank gray screen.

I recently downloaded and installed Mountain Lion on my wife's late-2007 iMac. Unfortunately, each time, after the installer finishes and reboots, the computer sticks at a blank gray screen where normally the Apple logo would appear while things boot in the background. I have tried restoring from Time Capsule and re-downloading then reinstalling, but it produces the same result.
With the gray screen problem present, I've tried a Safe Boot, holding down Option to select a disk to boot from (nothing comes up when I do this, just the mouse cursor), and resetting the PRAM/NVRAM. I haven't really been able to find anyone else having this particular issue. The hard drive in the iMac is a little over a year old as we had to replace the old one. And from what my wife read, the late-2007 iMacs are Mountain Lion compatible.

saw this in another thread about a macbook pro slowing up after OSX Mountain Lion install:
the mac owner had mentioned his mac going very slow, and was told it could take several days for the new OSX to sort things out. Perhaps this explains my issue and perhaps yours.
"Yes this can be the case, even slow shutdowns and startups. But Hardisk space can also be a factor. Anything below the 10Gig mark of space left can cause extreme slowdowns."

Screen glitch on macbook pro when opening

When I open my Macbook Pro after it has been closed for a while the screen glitches. It happens for a few seconds and then goes back to normal.
I couldn't get a screenshot of it but it looks kind of like this (except filling the whole screen and slightly less dense):
I'm interested in how to fix it but more interested in making sure it isn't going to lead to greater problems. I can honestly live with it if I have to but I want to make sure it won't get worse.

Just select Print in Safari and then, in the bottom left-hand corner, select PDF and you can save it to whichever flavor pdf file you like.

The screen on my MacBook Pro Retina has horizontal lines and has a brightness flicker every few seconds since june 2013 upgrade of airport utility.

The screen on my MacBook Pro Retina has horizontal lines and a flicker every few seconds this happened after this weeks Airport Utility 6.3 upgrade.

Hi John,
I would take your machine into a Apple service center. Its highly likely a hardware issue. The most likely issue being the display has failed. If there is no external damage to the machines display they will replace the whole display under warranty for you.

Photoshop CS5.1 Won't Load Images On Screen at retina MacBook pro.

Photoshop CS5.1 Won't Load Images On Screen at retina MacBook pro. Any help? Thanks!

I'm surprised that Apple would attempt such a "hack" design... Switching graphics adapters mid-stream is no small task, and I can't imagine that they could ever make it work seamlessly.
Keep in mind that the nature of the complex GPU beast is that graphics hardware doesn't all work the same (or right) and application software has to make decisions about what to do and what not to do, and even when to invoke certain workarounds - or it would never be possible to run on multiple platforms.
Yes, that seems wrong, but it's necessary and it makes developing cutting-edge graphics applications in the real world much more expensive.
The decisions aren't re-made by an application all the time - that would slow things down terribly. Instead, often the run-time environment is characterized at application startup and the features remembered for later use. Modern applications actually even create programs (e.g., shaders or OpenCL programs) to run on specific GPU hardware, and they have to be compiled - something usually done by the application at startup.
Now imagine that someone changes the capabilities of the graphics hardware completely after the application has started - even from one vendor's implementation to another (Intel to nVidia).
Like I said, I'm surprised a reasonable system designer could ever think that swapping GPUs at run-time could be made to work. At least Apple allows you to turn it off!
Does Apple offer any "geek-level" configuration options that can force the use of a particular GPU for a given application? It seems that this could be an automated workaround that would allow a given application to see only one GPU, which is what Photoshop appears to need here.

Can I purchase extended warranty for macbook pro after 1 year warranty expired?

Can I purchase extended warranty for macbook pro after 1 year warranty expired? Macbook bought 2011 November?

OK thanks for your replies.
Now if something goes wrong how can my Macbook Pro be fixed cheaply. Two of my friends have bills for $1300 and $1100, one to repair motherboard another is to replace screen. One has extended warranty.
Is there a cheap way to get a macbook repaired.
Thanks.

Safari: Pages begin to load and then go to blank gray screen?

Hi there. I am using Safari 6.1.1 on a late 2009 iMac. I've never had this problem before, and it's worth noting that Safari does not actually crash -- it remains responsive but the pages don't load properly. They begin to load and but it's as if, the instant the full page appears, it cuts to a blank gray screen. It doesn't happen with absolutely every site but it occurs with the majority I'm visiting. Obviously it makes Safari unusable so I'd appreciate any help that could be offered. Thanks.

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you boot, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, reboot as usual (not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

MacBook Pro - After Battery dies I'm not able to type in login window, until forcing a restart

Hi, as mentioned in the header : MacBook Pro - After Battery dies I'm not able to type in login window, until forcing a restart
After the battery drains to 0% the computer switches off.... *Makes sense*
Once I put the charger power chord back in for an extended period of time I hit the power button and then see the login screen.... *Makes sense*
However it won't let me type into the login box therefore having to force a restart and lose any saved data or data open when it died of battery. *WEIRD*
This happens every time my computer runs out of battery. I understand that obviously not letting the laptop die is a good idea, however it seems like there is something wrong as it allows me to login yet won't let me type anything...
Any solutions? Anyone else experience this?
I have an early 2012 MacBook Pro - 15 Inch Screen.

Hi s4mboy,
Thanks for visiting Apple Support Communities.
I'd start with resetting the SMC and PRAM on the MacBook Pro:

I just tried to wake up my 4 year-old MacBook Pro after perhaps an hour of inactivity, and it just 'pinwheels' and won't restart. HELP!!!!!!!!!

I just tried to wake up my 4 year-old MacBook Pro after perhaps an hour of inactivity, and it just 'pinwheels' and won't restart. HELP!!!!!!!!!
Semi-experienced user - Western New York.
System was operating nominally until I opened it from 'sleep' mode after ~1 hour of inactivity.
No idea what's going on. I had just installed a Flash Player update [not an atypical occurrence] at ~6:00 PM this evening, but used the system without incident after that. Re-Start attempt does not appear to succeed, the circular pre-OS icon never clears and displays the authorization screen.
Anyone with an idea how to help would be greatly appreciated. We have so much personal and business data on this machine!!!
Thanks!
Jim F.

Press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly to restart.
The fact that you're worried about the data implies that you have no backups, or that you don't have confidence in your backups. Your first priority must be to back up all the data you intend to keep. Ask if you need guidance.

When I turn on a video the screen on my MacBook Pro freezes. I've been through Apple Care and they couldn't fix the computer. I think the fan and the graphics are the problems

When I turn on a video the screen on my MacBook Pro freezes. I've been through Apple Care and they couldn't fix the computer. I think the fan and the graphics are the problems. I can restart after two attempts. Sometimes I use SAFEBOOT

Please advise the model MBP you have and the OSX you have installed.
Also try a SMC reset:

Start up to black screen 2011 15" macbook pro

start up to black screen 2011 15" macbook pro does the start up chime and apple screen, then to a black screen, mouse arrow is visible and keyboard lit. help please

I had the same issue with my Macbook Pro too. You can follow this steps below:
1. Shut the computer down by holding the power button for 10 seconds
2. Restart the computer and press shift at the same time until you see the progress bar start moving
3. Once you reach the point where your screen goes dark and you see the cursor, type the first letter of the username for your computer, then hit Enter, then type your password, then hit Enter.
4. After a moment, you should see the spinning beach ball
5. Your screen should then move on to something along the lines of "Completing OSX Installation" (I can't remember the exact wording). Let it finish. After that it should go to your normal desktop and the issue should be fixed. (If your screen goes pitch black during this process, hit the space bar. I thought it wasn't working, but the screen was just sleeping).
Apparently it's an issue with an automatic update that never quite got past the login screen.
Hope this helps!
