My Macbook pro is Start up with white screen without apple logo - stuck and can.t do any thing

Hi friends, I am stuck in my MacBook pro which shows white screen .
1- I tried hold C to Bogor from DVD to reinstall Mac os x , but it's not working .
2- I tried hold Shift and option to log to safe mode , but it's not working .
3 - I tried reset ram , but its not working .
Any advice ? I am stuck and can't do anything :(
Regards

It would be helpful to know which MBP you have and which OS you're running.
Read the following and try the advice listed here: http://support.apple.com/kb/TS2570
Ditto: http://support.apple.com/kb/TS4088?viewlocale=en_US
Also, some things which cause a gray/white screen cause it to take much longer doing anything, so you may want to try some of your previous efforts and wait 5 minutes or so after each.

MacBook Pro not starting up, has faint lines across apple logo and runs hot

Hello, my MacBook Pro 2011 model is not working. I when trying to start it up it has faint horizontal lines, equally spaced, all across the screen. When the apple logo disappears the machine stops progressing any further, and starts running really hot. Yesterday I had to run the batter flat before I could get it to start properly and it ran all day fine. Today it logged in but then went haywire with split desktop and horizontal lines and crashed. Can't get it to restart.
i haven't a clue what's wrong, and I can't afford to replace it right now. Any ideas anyone?
blessings,
DAvid

Are you referring to SMC and PRAM resets?

If not, try them:

MacBook Pro won't boot. Grey Screen appears, apple logo then nothing

I'm very frustrated. I was using my laptop and suddenly the rainbow wheel appears and it freezes. I tried to hard reboot it and when it restarted a grey screen appears and the apple logo shows up. I bought it used from a Micro Center and I believe it's out of warranty. What is going on and what are my options?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 3
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 4
Boot in safe mode. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
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.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 7
Repeat Step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 8
This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. Both desktop and portable Macs used to have such a battery. The logic-board battery is separate from the main battery of a portable. A dead logic-board battery can cause a boot failure. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. If you can't get to an Apple Store, go to another authorized service provider.

My macbook pro when started has a white screen with flashing apple, file with question mark and stop signs...any ideas how to reboot it? command R doesn't work

Any help appreciated please.
After a while of being like this is turns off.

You may have to reset your MBP PRAM:
http://support.apple.com/kb/ht1379
The boot drive may need repair in Disk Utility>First Aid (verify and repair)
Critical system files may be damaged which will require that the OS may need to be reinstalled.
The connection to the boot drive is faulty.
The HDD has failed and needs to be replaced.
Ciao.

MacBook Pro White screen, No apple logo, No question mark

Hi guys
I've MacBook pro 13 2010 model
The Laptop turn on all the time when i press power button
but It's stuck in white screen ( without apple logo ) . With hard drive connected or no hard drive i still can't see the question mark folder
What i've done
- Reset NVRM ( shift + Command+ option + power ) and it worked as i can see light changed in the charger
- I removed the hard drive put new one, then again removed hard from the board but no luck
- connected the Laptop to a monitor but not even showing video in the external monitor
Why can't i press PRAM button. NVRM work OK but not PRAM ( Option + Apple logo + P + R )
so keyboard is fine

askmeplz82,
if you’re unable to boot into Mountain Lion’s Recovery mode, then that limits your self-help options. These options still remain:
Do you still have the two grey installation DVDs which originally came in the box with your MacBook Pro?
Do you have a bootable external disk?
Do you have access to a FireWire cable and access to a second Mac with a FireWire port?
Do you have a spare SATA disk which can be temporarily installed inside of your MacBook Pro?
If the answer to all of these is no, then your only remaining option is to make an appointment at an Apple store or other qualified service facility so that they can diagnose/repair your MacBook Pro.

Hi..
Your profile indicates you are running Lion v10.7 so you need to use Lion Recovery to repair the startup disk if necessary or reinstall Mac OS X.

My early 2011 Macbook Pro on start up has wifi, but drops it soon after and never comes back, AHT shows nothing wrong. Multiple wifi's tried and same on all.

My early 2011 Macbook Pro on start up has wifi, but drops it soon after and never comes back, AHT shows nothing wrong. Multiple wifi's tried and same on all. I have also re-installed OSX from scratch and still happens.

I have the same problem. I have a white macbook 2010, with mavericks os. I just found my mac not powering on and then I tried to run it on safe mode by holding the shift button but it will turn off seconds after I let go of the shift button. I am able to access the desktop and use it while holding the shift button the whole time. It's a bit slower than before but I figured maybe it's because of holding down shift button.
I went to the Apple Store to have them look at my mac and I was told it's a failed hard disk. I wasn't told why he was able to conclude that a failed hard disk is causing the problem, I was just told to get a replacement. But the thing is when I ran Disk Utility it says, "disk appears to be okay." So I also feel like it's possible it's not a hard disk issue because it's also the first time it happened. My mac was working perfectly fine before all this.
Do you know anything else that could cause this problem? Were you able to find out what's wrong?
Thanks.

I am sharing my macbook pro over a network with windows 7, however through windows 7 I can access my whole computer instead of just the shared files!

Hi Sig,
The issue is that i only want the shared folders to be accessed through windows 7.
Whats the point otherwise to have shared folders?
thanks..

In a macbook pro i7 2.66 with DDR3 1066 MHz ram, mid 2010 I can put two 8GB ram each, I gained speed or recommend

In a macbook pro i7 2.66 with DDR3 1066 MHz ram, mid 2010 I can put two 8GB (1333 MHZ) ram each, I gained speed or recommend, or is it better for me to stay with 8GB, 4GB memory in two 1066 each

Stick to the specs give in your user manual. There is no benefit to installing faster rated RAM. It won't run any faster. Furthermore, it may not work at all.

IBook will not start up past gray screen w/ apple logo

iBook will not start up past gray screen w/ apple logo. So I have zeroed out the hard drive and reinstalled tiger. No change except if I start up holding shift it will boot and welcome comes up then black screen that says you must restart by holding down power key.
Zeroed out the HD again with same results. Also I have a iBook G3 with the same symptoms.

What you are experiencing is a kernel panic.
Try starting up from the Mac OS X Install Disc by inserting the disc and restarting your computer, holding down the C key as the startup chime is ending. Then choose Installer > Open Disk Utility (in Panther) or (in Tiger) click 'Next' at the language screen and choose Utilities > Disk Utility and select the hard drive in the left column. Choose the First Aid tab. Click Repair Disk to test and repair the hard drive.
Once you have repaired the hard drive with the Install disc's Disk Utility, then try to restart normally, and go to Applications > Utilities > Disk Utility. Click on the top hard drive icon in the left sidebar and note the S.M.A.R.T. status at the bottom right of the pane. What does it say?
Select the named boot volume in the left sidebar, ("Macintosh HD" unless you've renamed it). What is the hard drive capacity and how much space remains available on it? Repair permissions on it.
See if a little hard drive maintenance helps things out.

I Am Having Trouble With Mozilla Firefox. For Some Reason I Can Not Type Any Thing In

I Am Having Trouble With Mozilla Firefox. For Some Reason I Can Not Type Any Thing In. I Can Not Type Anything Into Yahoo Search Or Any Where I Need A Password. Anytime I Try To Type Anythink In It Locks Up Firefox The Same With Thunderbird Can't Write An Email Thunderbird Locks Up When I Start Typing. My Roboform Will No Longer Fill In The Forms. I Have Uninstalled All Three Programs Three Times. Can You Give Any Help.
Thank You

Hi,
Sounds like you have two problems there. One for Firefox and one for Thunderbird.
We can help you with the Firefox question but your other Thunderbird question will have to go into the Thunderbird queue. You can create a new Thunderbird question by going to [/questions/new/thunderbird]
Can you try to start Firefox in Safe Mode to see if Firefox works properly with no error? You can start Firefox in Safe Mode below:
*'''Windows/Mac''': Go to Help > Restart with add-ons disabled
*'''Linux''': Run ''firefox -safe-mode'' in the Terminal/Konsole
If Firefox opens up fine with no problems, it's probably one of your extensions that's causing the issue. You can re-enable your add-ons one by one until you find the one that causes the issue upon being re-enabled.

Mac Book Pro starts up to white screen then makes a sound and dies, turning off

Hello, my macbook pro is new, bought in August 2011. Just recently my battery died prematurely after only 118 cycles. However, the hard drive also had to be replaced as it wasn't for some reason working with the battery. Now, my computer even though the battery works and I've passed all my documents to the new hard drive is having problems when it starts up. It makes the typical apple sound when it turns on and it goes to the white apple screen and unexpectedly dies off (turns off). It makes a sound as if everything is starting off then a dying sound when it turns off. Sometimes I try it again and it turns off or it can also turn on randomly and fully boot. Holding the shift, control and alt key while it is connected to the battery until the charge changed color works but it is not a permanent solution as this problem has continued for a week. It occured a couple of days after replacing the hard drive and battery at the genius bar. Any help?

It is better to take it back to the genius bar.
Your MBP is under warranty and let them fix it for you.
Nobody here can help you with hardware problems.
Best.

2011 Macbook Pro white screen after apple logo and spinning wheel

Hey there guys,
My 2011 Macbook Pro has encountered some problems. Firstly while i was at school, i opened up my computer, usually the computer would require you to type your password, but my login page became fuzzy, white lines everywhere. So I restarted my computer and everything was okay. After that i came back home, my computer was running fine, after surfing the net for a few hours, my whole computer suddenly became blue. So what i did was i just restarted my computer, after that my computer would boot up Apple logo would come up, the spinning wheel would also come up, after 30-40 secs it would turn black screen and come back on as a white screen and would just stay like that. It would be on the white screen. Tried some rebooting ways but all didn't work.
1st: I wanna know whats the problem?
2nd: Is this a harddrive failure? (Because i have alot of important documents and personal stuff in my hard drive and i hope it isn't a crashed hardrive)
Thanks for your help..
PS: Im running on Moutain Lion, but i have no idea what version it is.

Make a "Genius" appointment at an Apple Store.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Keeping your confidential data secure during hardware repair
*An SSD doesn't need to be zeroed.

My Macbook Pro won't get past white screen....

My Macbook Pro is stuck on the white screen with the gray apple logo and loading gear spinning below---for hours now. Restarted multiple time without any change. Agh!

Boot in safe mode. First, disconnect all wired peripherals except keyboard, mouse, and monitor, if applicable, and remove all aftermarket expansion cards. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Safe mode is much slower to boot and run than normal.
If you can boot in safe mode, try rebooting as usual (i.e., not in safe mode.)
