Macbook Pro Boot Issue, White Screen with Apple

Having a similar issue with my macbook pro. When I press the power button, a white screen appears with an apple icon in the middle and a small cirle on the bottom that is like a timer. I thought that the computer might be downloading something, but I left it on for hours and the computer didn't get out of that mode. I have tried several things such as the installation cd, first aid repair, but both said repairs weren't needed and that the drives were fine. Any suggestions on why the computer is doing this? It's been several days and I shut if off, leave it off for an entire day and when I turn it on, the same screen with the apple appears and nothing else.
Any ideas are appreciated!
Thank you!

Hi Claudiat :
You could try a SMU reset, which may solve your problem,
from Apple:
MacBook, MacBook Pro
If the computer is on, turn it off.
Disconnect the AC Adapter and remove the computer's battery.
Press and hold down the power button for 5 seconds and then release the button.
Reconnect the battery and AC Adapter.
Press the Power button to restart the computer.

Macbook pro boots to white screen and a ?

macbook pro boots to white screen and a ?

Gus@MaggiesFarm,
try this: boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the Mac OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Does it get past the white screen now?

Macbook Pro boot shows black screen with white text cursor

Hello,
I have a MacBook Pro 7,1 MC374xx/A running Mavericks. My box has two internal hard drives in it. One had the Mac OS installed to it, and the other has absolutely nothing on it. I decided to give Boot Camp Assistant a try and chose the hard drive with nothing on it to install Windows on. I also had an external USB DVD drive attached with the Windows 7 installation disc on it.
So, next thing ya know, my Mac reboots and loads a black screen that says "Memory Overload." I take out the external USB drive and restart. Then it said, "No boot devices found." Now for whatever reason, it's just a black screen with a white text cursor.
What the heck happened?
I selected command R and confirmed that I installed Boot Camp on the right hard drive (the drive that did not contain my Mac OS). Then, I completely erased everything from the drive with Boot Camp on it. But still..black screen with white text cursor.
I have no Time Machine backups available so I'm forced to reinstall the OS. Any idea why this happened? It seems I must have attempted to install Boot Camp improperly. Any ideas or instructions on what to do now or how to install Boot Camp successfully on the Macbook Pro I own?
Earnestly,
Speck

My macbook pro 2011 shows grey screen with apple logo and want start

i was just using my macbook pro and it freezed for a while not responding and i turned it off by pressing the power button. afterwards, i turn it on and it shows a grey screen with apple logo but want start pls somebody help me because am having "my life" on the machine

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 Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. 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 by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. 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
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 3
Boot in safe mode.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
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.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
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 damaged 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 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
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
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to 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.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
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 backup.
Step 8
A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
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.

Boot Camp: Early 2011 MacBook Pro boots to black screen with blinking cursor after windows 7 installation.

I bought and downloaded the windows 7 ultimate edition 64 bit iso, then proceeded to perform a correct burn to a DVD one at the slowest speed and one at the fastest. all went well. so I open Boot Camp assistant and follow the instructions to the letter, downloaded the driver support to the flash drive. partitioned my drive with more than enough room 150 gb. its starts its install. I get through everything seamlessly where I put in my info all with the exception of my activation code. yet it still continues to finalize the install and does another restart. boots back up to either A. black screen saying press any key to boot to my install disk. B. if I take it out just a white curser. also I read it may be because I had the flash drive in while I was trying to boot so I removed it as well, same result. any input would be much appreciated.

Macbook Pro stuck on white screen/Grey apple logo

I have tried all i know to get this thing back to my desktop.
It will just sit at the White loadup screen with the progress circle spinning for hours and hours.
I've tried resetting PRAM, I've tried starting it in safe mode and neither of those worked
I inserted the original mac os x disc and held down C...spit the disk back out while displaying a "?" inside of a grey folder. Any suggestions?

Hi c,
If you can get it to boot from the install disc again (just keep trying), run Repair Disk (and also check S.M.A.R.T. status while you're in Disk Utility).
Repair Disk: Boot from install disc (insert disc>restart>immediately hold down c key and keep holding it until you see “Preparing Installation”)>at first screen select the language and click Continue> click on the Utilities Menu in the menu bar>open Disk Utility>select your HD in the panel on the left side>click Repair Disk at bottom of main window. Run this at least twice, and keep running it until it says “appears ok” twice in a row. If that doesn’t happen, you may need a stronger utility such as DiskWarrior or if the directory is damaged beyond repair, you may need to reinstall the OS, or you may have a damaged HD (repair utilities can only repair the directory structure, not the HD itself).
If the HD has issues, it may be that the optical drive has issues too, and as iV stated, cleaning it would be a good start.
If the HD is good, it still could be the optical drive, but I'd also try running Apple Hardware Test from the install disc.
RAM and the logic board are also suspects.

Macbook Pro stuck on grey screen with Apple logo

Macbook Pro was purchased in mid-late 2009 and is running on OS X 10.6. Today is suddenly stopped responding and so I turned it off. When I turned it back on it opend to the grey screen with the Apple logo and the loading icon and that is where it stayed. I have been searching for the answer on different forums but have yet to find a solution. My hard drive is appearing in the Disk Utility but not in the box when I try to reinstall OS X. Any suggestions on what to do?

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 gray screen at boot. 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.

Computer doesn't boot, stuck in white screen with Apple logo

I got a friend that has a MacBook 2.0GHz, Black. The computer had some sort of problem so he took out the HD and placed it into another computer (MacBook 2.2GHz, Black). For some reason whenever the computer boots, it gets stuck in the white screen with the gray Apple logo, and shows up a bar, as if it's loading some sort of firmware update. It never advances, and it doesn't go thru.
If he takes the same HD and puts it into an enclosure, first it would take a while to mount in another computer, and afterwards it would give some errors, but now it doesn't even load.
Before he had the issue with his original computer everything was working fine, and there was no update going on when the computer got broken. The problem that that computer has isn't related to the HD.

If you have physically removed the drive and connected it to another computer and it "took a while to mount" then it sounds like the drive itself is failing. Hopefully he maintains backups.
Boot the MacBook in "verbose" mode (press and hold down option+v while powering up)
http://support.apple.com/kb/HT1492
In this mode you will see all the boot messages scroll by instead of the typical white screen with Apple logo. You will likely be able to see messages indicating what the computer is trying to do -- for example messages indicating that having failures or retrying to read the hard drive.
The access arms on hard drives have to be precisely located above the "tracks" on the disk in order to read data. As the drive ages & wears, the accuracy of the arms can become sloppy, causing the read/write head to no longer be precisely located over a track. This results in failure to read correctly. Most drives have a useful life of about 5 years -- after which the failure rate will go up substantially. Fortunately, replacement hard drives are cheap.

My macbook 13' (older version) starts only to white screen with apple logo tried to rebooot by pressing shift at the opening but it didn't finish starting before stopping please help anybody please

is anbody there how does this work never done it before my macbook won't start past white screen with apple logo any ideas ?

Are you using a 10.6 Snow Leopard Install DVD? If yes, you can erase and install following these directions: http://support.apple.com/kb/HT3910
You'll know whether or not it is a hard drive issue when you get to step 8 under "Part One: Erasing the hard drive". If you do not see your hard drive in the list on the left side of the Disk Utility window then you know the Mac isn't seeing it—could be a loose cable, but more likely hard drive failure.
If you can see it on the left, click on it and look at the bottom of the Disk Utility window. If you see something like "S.M.A.R.T status: failing" that is definitely a hard drive issue. Otherwise, you can just follow the directions for an erase and install!
Might be worth fixing depending how much a repair would cost. Genius Bar could at least diagnose it for you and give a repair estimate. I'd look at what a new or refurbished one with your same specs would cost though to see if the price differential is worth it...

Gray, Blue or White screen at boot, w/spinner/progress bar

Imac wont boot - i get a white screen with apple logo, and it loads to about 10%, then screen goes black

imac wont boot - i get a white screen with apple logo, and it loads to about 10%, then screen goes black

Hey there mtriest,
It sounds like you are unable to boot the iMac successfully as it keeps shutting down when you try to boot. I suggest the troubleshooting from the following article named:
Mac OS X: Gray screen appears during startup
http://support.apple.com/kb/ts2570
Disconnect, test peripheral devices and network cables
Note: "Peripheral devices" refers to external devices other than what came with your Mac, such as hard drives, printers, or hubs that you connect via a USB or FireWire cable.
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Disconnect all peripheral devices such as external hard drives or printers (leave only the display, a keyboard, and mouse connected).
Disconnect any Ethernet cables.
Start up your Mac.
If you can start up this way, one or more of your peripheral devices (or installed software related to the device) is probably causing the gray screen issue. Connect one device, then restart your Mac to test for the issue. Repeat the process until you locate the device at issue. Make sure the device is powered if it needs to be to operate correctly. Check with the manufacturer of the device for support or possible software driver or firmware updates that may be available for the device. Try a different cable with the device if possible (such as a different USB or FireWire cable).
Note: If you have multiple peripheral devices and the issue only occurs when they are all connected, but not when each device is the only peripheral connected, see the Additional Information section below.
If you are using a desktop Mac with a third-party keyboard and/or mouse device, and the issue still occurs, try starting up with an Apple keyboard and mouse connected instead. Try starting with no keyboard and mouse connected, then connect them after start up. Also, try a different USB port on your Mac.
If the gray screen issue persists with no devices connected, go to the next section (with the peripherals still disconnected).
Perform a Safe BootSimply performing a Safe Boot may resolve this issue.
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Start your Mac, then immediately hold the Shift key. This performs a Safe Boot. Advanced tip: If you want to see the status of a Safe Boot as it progresses, you can hold Shift-Command-V during start up (instead of just Shift).
Note: A Safe Boot takes longer than a typical start up because it includes a disk check and other operations.
If your Mac starts up as expected, immediately try restarting.
If the Safe Boot does not work, or the restart after a successful Safe Boot does not work, go to the next section.
There is additional information in the article with further troubleshooting if needed.
Thank you for using Apple Support Communities.
Cheers,
Sterling

Restarted my MacBook Air, just have a white screen with apple . Will not start up

Restarted my MacBook Air, just have a white screen with apple . Will not start

What version MacBook Air do you have? Usually identified by the year you bought it, i.e. mid-year 2012, 2011, etc. Also, what OSX are you running? (please provide OSX ver number, i.e. 10.8.2 for latest Mountain Lion, etc.)
Not sure I can help you directly but for others to lend a hand, they'll need to know this information to make a sound suggestion. I see you're new to posting here so this will help you in the future.
Good luck.
