Macbook stuck on white screen with apple logo. help please

I have a macbook (black model) and while I was surfing on internet it is frozen. so I shut it down and restarted. When I restarted, it stuck on white screen with gray apple logo and seems like booting but nothing happens.
after that, I restarted again and put installation disc (leopard) without pressing any key and it opened normally. I backed up os with time machine but in one hour it is frozen again.
restarted again but this time it did not boot normally. so i tried booting from cd with c key, it opened installation screen. I have opened disk utility top repair disk, but when I click on disc image, repair / verify disk buttons are unavailable to click and S.M.A.R.T status is not supported.
After all, I tried to erase and install system several times, but after language section when I click agree to terms and conditions, mac freeze again.
So, I do not know what to do. Any help please?
Note: I already tried PRM and Safe Mode. (after safe mode it took me to installation screen again and nothing changed.)
Any help would be much appreciated!
Uptade: Also, opened system profiler and clicked on Serial-ATA, it seems loading but do not show any info. stucked again! help please

HI,
*"I have opened disk utility top repair disk, but when I click on disc image, repair / verify disk buttons are unavailable to click and S.M.A.R.T status is not supported."*
You need to select "MacintoshHD 10.5.8 not "disc image" in order to run Disk Utility and Verify and if necessary, Repair the disk.
That's why you are seeing this dialog.
*are unavailable to click and S.M.A.R.T status is not supported.*
Also, run the Apple Hardware Test.

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?

Create a data recovery, undelete boot drive

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.

Ipad mini stuck on white screen with apple logo

I have a new iPad mini. only had it 2 weeks. used it this morning everything was fine. pluged in to charge, when I came back it is stuck on white screen with apple logo. I tried to reboot. that did not work. please help.

Have you tried resetting your iPad?
Reset: Press the Home and On/Off buttons at the same time and hold them until the Apple logo appears (about 10-15 seconds).
No data will be lost.

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.

Mac stuck on white screen with apple logo at startup

It's a few days i have this issue.
When i turn on my macmini (late 2009) it does the startup sound, but when the white screen with apple logo appears it stucks on that screen.
To solve this problem i have to unplug the power connector, when i restart it works normally.
This happens randomly, not at every startup.
I switched from normal HD to ssd HD (brand new one), i have the same problem with both HDs.
Since black outs are not good for computers i woult solve this problem.
Does anybody have my same issue or know what's wrong?
Thanks!!!

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.

Stuck on white screen with apple logo

A few days ago my macbook pro started making a weird buzzing noise and froze. I waited for a while until I shut it off. When I turned it on again it froze at a white screen and after a few minutes it was a white screen with the apple logo.
I kept waiting, and after a while my mac restarted and it happend all over again. I then tried to find something here to help, and I tried everything!
I tried the disk utility thing and when I tries to verify the Macintoch HD it said "The volume could not be verified completely. Error: This disk needs to be repaired. Click repair disk." I did that, but then it said "Error: disk utility can't repair this disk... Disk, and restore your backed up files."
what should I do now?
Also I tried the safe mode thing when I start up the machine, but that doesn't seem to work either.
I haven't backed up my files either.. So, I don't know what to do, and I don't want to lose my files. Can I do something about that? Please help me!

HI,

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.

IMac Stuck on White Screen with Apple Logo

Currently own: iMac 21.5" 2009 version with Snow Leopard, 4GB Ram, 500 GB Hard drive
This computer was sitting in storage of my basement for 2 years because I was out of town on business.
When I came home the computer worked fine. But earlier this evening it was on sleep mode and the dreadful color wheel was on. So I rebooted it, only to see that it was stuck on the white loading screen with the Apple logo. And nothing more. Panic struck me and I tried restarting it again, to no avail. Then I tried rebooting in Safe mode- but it won't respond. THEN I called Apple Care, and they tried to have me go through the process where it checks the Hardware. It took 45 minutes and then the screen said "It was modified", or something to that degree. But when we reboot it, it returned to the white screen.
I am so upset. I now have an appointment with the Apple store on Monday. I don't have a warranty anymore. How much is it going to cost if they have to replace to hard drive? I thought Apple computers were meant to last! This is beyond ridiculous! I had not downloaded anything wrong, wasn't on crazy websites. It still had over 350 GB of space left. Why didn't the tests we did over the phone work? Is my computer broken? I do have an external hard drive with Time machine, so I am not concerned about losing my data. I am, however, concerned about shelling out another $1500 for a new computer!

If you are taking it to Apple they will fix it for you, but they will install Snow Leopard. If you want the current Mavericks you can download that yourself from your home and install it. This is dependent somewhat on what model you actually have.
Upgrading from Snow Leopard to Lion or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99.
If you sign into the App Store and try to purchase Mountain Lion but the App Store says your computer is not compatible then you may still be able to upgrade to Lion per the following information.
A. Upgrading to Mountain Lion or Mavericks
To upgrade to Mountain Lion or Mavericks you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion or Mavericks (Free) from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion — System Requirements
     OS X Mavericks- System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer) — Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) —
             Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) — Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) — Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) — Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) — Model Identifier 3,1 or later
         7. Xserve (Early 2009) — Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
Are my applications compatible?
         See App Compatibility Table — RoaringApps.
B. Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
I can't help you any more if you don't have the installer DVD, so you will have to wait until Monday. I had hoped we might get you working before then, but that isn't going to happen, I"m afraid.

Macbook Pro stuck at white screen on startup. HELP!

Right when i turn on my macbook pro, it plays the startup sound and gets stuck on the white screen. I can hear it running my cd right when the computer starts up. no matter what i do, i cannot get out of the white screen. it just stays there. same thing every reboot. Whats going on???
HELP ME!

Hi, I had this exact same problem with my 15in mbp just before Christmas. I shut it down one afternoon, and then later in the day switched it back on. It wouldn't boot past the white/grey screen. It wouldn't even get as far as the apple symbol. I tried to start it up several times, but to no avail.
I called up apple support, and they had me run through various keyboard combinations at start up. Nothing worked. According to my observations and the apple telephone operator's knowledge, it was as if the keyboard wasn't booting up at all during the startup sequence, hence it was not responding to the key combinations. There was no fix available over the phone and the advice given to me was to take it to an Apple Store to have the keyboard replaced. Living in Prague Czech Rep, as I am, there is no apple store, only one reseller, which I resolved to take my mbp to the next day.
However, before the night was up, I decided to to do one more thing. According to my (less-than-Vulcan) logic, since I was taking it to be opened up, and knowing that since the dawn of time, hitting machines has seemed to give them a new lease of life, I decided to see what a sharp thump to the side of the computer might do. It wasn't overly forceful, just enough to make me feel satisfied. Would you believe it, the **** thing started up the next second I pushed the power button!
Well, I had many weeks of uninterrupted, blissful computer use until a few days ago. If you haven't heard, quite a few mbp users have been reporting cases of unresponsive keyboards and trackpads whilst running leopard, leading to kernel panics and I have now unwillingly joined their ranks. I am in no way an authority on computers (I think that's rather obvious from my repair technique mentioned above) but I have a suspicion that my little episode last Christmas is related to the current issue of the internal keyboard and trackpad becoming unresponsive, so I'd watch out for that in the future once you're able to get your laptop up and running again. There doesn't seem to be much information as to why this is happening, but for my part, I've found that it's more frequent if pressure is placed underneath the battery, and less frequent under Tiger than Leopard.
I really hope, you're able to get your mbp up and running again. I know how utterly frustrating it is when it's not working and you have no idea why.

Mbpr won't boot up, stuck on white screen with apple logo when I turn it on

This morning I noticed the apple logo on the outer shell of my mac was lit up, I thought this was very odd because the lid was closed and like all laptops when thier lids are shut the display ect. are supposed to switch off/go to standby?
Anyway I quickly opened the lid of my laptop to find that iconic white boot up screen with the grey apple logo and the small spinning loading circle under it
I've waited nearly 5 hours and tried multiple thing like booting up in safe mode, single user mode, and evan reinstalling OS X mavericks somebody help me please

Read this article... It recommended something you did already but there are other troubleshooting tips I'm not sure you've tried.
http://support.apple.com/kb/TS2570
If none works, then a trip to the Apple Store is needed. It's most likely a hardware issue that you yourself cannot resolve.

Updated iPhone 4s to ios8 but screen is stuck on white screen with apple logo and progress bar

I updated my phone last night and my iPhone screen is white and has a gray apple logo and a progress bar which has been the same for 12 hours. The bar looks almost completel but it hasn't moved at all. my phone was also unplugged accidentally during the night while it was on this screen. would that have any effect?

Turn it off, go into recovery mode (command R at boot), wipe everything, go back and install Yosemite. Its suggested that you are using ethernet as it goes a lot faster that Wifi and more reliable. If you do not have a ethernet cable, you can still use Wifi. Hope this fixes your problem.

My macbook shows a only white screen with apple logo and spinning wheel when i on the power button? How can i correct that?

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.
