MacBook 2010 won't get past loading screen

Hi everyone. I don't live anywhere near an apple store so am hoping I can get some help here. My MacBook won't get past the initial White loading screen with the grey apple logo. A loading bar (which I've never seen before) comes up, loads about 1/5 of the way, disappears, comes back empty, does the same thing then my laptop turns off. About two weeks ago the battery stopped working without being plugged in and each time I turned it on it had reset the date to 01/01/2001. Any advice would be greatly appreciated. Thank you.

Welcome to the Apple Support Communities
The hard drive is damaged. Insert the Mac OS X DVD, press C key when your Mac starts, go to Utilities > Disk Utility and repair the drive. If it doesn't work, take the Mac to an Apple Store.
If you haven't made a backup, download DiskWarrior

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.)

My MacBook Pro won't go past load screen when you first load it up?

Three days ago it was working fine all of a sudden froze so I did a hard shutdown, ever since has gone to screen with loading symbol.

Try SMC reset:

Note that the directions are different depending on whether or not the battery in the MBP is user removable.

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 startup failure is to secure the 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 the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from 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.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start 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.
d. 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
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up 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.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start 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 the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up 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, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup 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 restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the 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 restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

IMac won't get past startup screen, no matter what. Pls help?

I just inherited a mid-2010 iMac from a friend. It hadn't been used for months, and now when it is started up, it won't get past startup screen. It shows the 'slot' looking image on the bottom of the white loadup screen, then it's just the apple symbol and the whirly thing going around forever. I've had it going for over half an hour at one point, and nothing changes. I have tried all the different reboot key combos, such as C with a startup disk in it, D for hardware test, command S for safe mode, etc. The only thing which makes any difference at all is using the T key at startup, when I do get the three-pronged white symbol floating around screen.
It is a 21 inch with 500gig, and I believe it's running Snow Leopard. They never had a problem with it before, but now after the months of disuse, it is doing this. Please, can anyone help? Thanks!

I'm not sure if a dead PRAM battery would give you these symptoms, but one possibility is that if the computer was off wall power for months, the PRAM battery, a small coin cell battery that controls certain functions, may be drained and dead.
But, in any case, try an SMC Reset. You must follow the timing for this exactly.
http://support.apple.com/kb/ht3964
And then a PRAM Reset.
Hold down Option-Cmd-P-R together at the startup chime, listen for two more chimes, total three, then release all the keys to finish booting.
You might also try a Safe Boot by holding down Shift at the startup chime. (Cmd-S isn't for Safe Boot, it's single user mode.) Give it much longer to boot than usual, but if it doesn't finish in perhaps 5 or 10 minutes, then you'll have to give up on that.

Won't get past "Platinum screen", keyboard not recognized

Hi all,
I just built a system, haven't even loaded up the OS yet. On the first boot, the computer won't get past the screen which says "Platinum" and says "tab to switch to post" or "del to run BIOS setup." The lights don't flash on the PS/2 keyboard i hooked up (a 6 year old Compaq one). I then tried a 2-year old Dell PS/2 keyboard with the same result. Is this problem fixable? I bought this off of Newegg and there is still time to return it, if I need to. Thanks for your help in advance. Also, if this topic has been beaten to death, I'm sorry. I'm in a state of panic right now since this computer isn't even for me.

I had the same symptoms first time I tried to boot my then-new K8N Neo2 Plat. I had the advantage of having the D-bracket, which was telling me it was hanging in the memory test. I had stuck in some cheapo memory to set up the board, waiting for my good stuff to show up. Turns out the memory was not up to the task. When I stuck in the good stuff, she fired right up. What memory are you using? Are you sure you don't have the D-bracket? it looks like a PCI back-plane USB bracket, except it has 4 LEDs on it (in addition to 2 USB ports and a 1394 port).

MacBook Pro won't get past the flashing grey file screen?

Ok, so tonight I try turning my MacBook on as normal, it then froze and I saw the rotating umbrella appear. So I restarted it. When trying to turn back on, the system did not load, instead a flashing grey file shape came up with a question mark inside. I have tried restarting with a number of key combinations, Option; option, ALT, P, R. Everything, yet it's not getting past this screen. Whenever I try to do an Internet recovery, it just stays on the wifi selection screen and I select mine, enter the password and then it just goes back onto the selection screen. Nothing is work yet! Incredibly annoyed as it has so much stuff, photos, music everything. I don't even know how I reinstall software as it's stuck... Can someone please help? My software is 10.7 I believe.

Hi PHXSuns,
If you are seeing a flashing question mark on startup, you may find the following article helpful:

MacBook Pro won't get off startup screen with apple logo. Help?

Could someone please tell me how I can get my macbook to get off that stupid startup screen with the apple logo? It won't go past that screen and boot properly. I have tried reinstalling OS X didn't work. I tried running a disk utility test and no errors where found. I don't have the time machine thingy so I couldn't try that. Is there anything else I can do before taking it to Apple and l
paying hundreds of dollars???

Computer won't get past OS screen after unlock, even if I am still using 2 cores

>Phenom II x2 555 BE
>MSI 870a-g54
So I decided to unlock my CPU and have been experiencing a problem. I recently found out that if I even have "unlock core" function enabled in BIOS, even while running it with two cores, the computer won't get past the windows screen. With four cores enabled it obviously does the same. No matter what I try I cannot get past the Windows screen while having the unlock core function enabled.
My BIOS isn't on the latest version. I tried flashing it but I couldn't start it up even after flashed, it gave me the same problem described above. I reflashed it to the version I'm on now and it works, but I still can't unlock. What gives?
Any help would be appreciated.
TL;DR: PC will run as Phenom ii X2 555, but not as Phenom ii x4 B55. Can't get past windows screen.

you need to provide more vcore to the cpu
first try to enable 1 core (core number 3) (disable core number 2 and 4) and increase some vcore. If booted then you have a good core.
Then try this with other core (core number 4) (disable core number 2 and 3), if booted then your both cores are unlockable and are good core (i.e, not defective)
then you can try all cores at same time with some voltage increase (vcore)

IPhone won't get past lock screen. Restart won't work.

My phone was charging and I took it off the charger, my friend played around and did the color invert thing (where you press the home button 3 times). Now it won't get past the lock screen. When I try to put in my pass code it just puts boxes around the numbers but won't actually press it. I tried restarting it, it's currently plugged into my computer and nothing. It was really warm when I first noticed this. Help!

It sounds like your friend also turned on VoiceOver, which speaks items on the screen as you touch them (and sounds like the Siri voice). You will need to go to Settings>General>Accessibility>VoiceOver and turn it off. However, with VoiceOver on the way you use the iPhone screen changes. First, to scroll you will need to flick the screen with three fingers. Next, to activate something on the screen you will need to first tap it once to select it, then double-tap it to activate it. Example: to open Settings, tap Settings once (the voice will say "settings"), then double-tap it again and it will open. The specific steps are:
Enter you lock code by tapping the first number once to select it, then double-tap it to enter it. Repeat for the other numbers.
Press Home.
Tap Settings. Then double-tap Settings.
Tap General. Then double-tap General.
Use three fingers on the screen to scroll to Accessibility.
Tap Accessibility. Then double-tap Accessibility.
Tap VoiceOver. Then double-tap VoiceOver.
Tap "On" next to VoiceOver. Then double-tap "On" to turn it off.
To fix the inverted colors, go to Settings>General>Accessibility and turn White on Black to Off.

IPhone 5 won't get past apple screen (keeps restarting)

Hello
Bought an iphone 5 just before the ios 7 release and for the last little while the phone would shut off a After a full charge when it hit approximately 97% of full charge it would shut off! Now it won't get past the apple screen and just keeps restarting over and over again.
Does anyone else have this problem with their iphone 5 and if so any solutions???
Our carrier Fido says this is an IOS 7 issue. Can anyone help
Thanks
Shep

Hey Shep77,
That definitely sounds frustrating! To completely isolate the issue, you may want to restore your iPhone in recovery mode, as outlined in this article:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/TS2802
iPhone is unresponsive and displays the Apple Logo
Review this article: iOS: Unable to update or restore.
.The above article also has great troubleshooting steps for Power issues, you may want to run through those if restoring does not resolve your issue:
Will not turn on, will not turn on unless connected to power, or unexpected power off
- Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
- Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion.
Learn about LCIs and corrosion.
- Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
- After at least 15 minutes, if:
               - The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
               - The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
               - Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
- If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
               - If the display turns on, go to step 4.
               - If the display remains black, go to next step.
- Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to
restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
- If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Thanks,
Matt M.

Mid 2010 MacBook Pro won't boot past blue screen

I've been having problems booting up my MacBook. I can't get past the blue screen. It went from booting slow at the grey apple logo screen to not booting up at all. Is it a problem with my hard drive? I also have boot camp running as well, but I can still see the boot camp drive for windows and my OS X drive, as well as my installation disk when I have it inserted when I hold the option key at start up.
I'm still able to run windows on it without any problems when I pick the windows drive. I tried different methods from different forums but I'm just not getting through. I tried holding 'c' to boot up from cd and I let it run over night but it never got past the grey apple screen with the gradient wheel (still spinning). I had already used time machine to back everything up before this happened since I was able to boot up properly (but slowly). Can anyone help? It's driving me nuts, and I can't remember what os/firmware version I'm running.

n your signature you said you are running 10.6.3. So let’s assume you are running Snow Leopard.
It sounds like your diagnosis of disk problems is correct. The OS X partition may be corrupt.
Try booting in Safe Mode.
http://support.apple.com/kb/HT1564
Try again to boot in normal mode.
If it will boot in Safe Mode but not in normal mode then you could have some 3rd-party software preventing the boot or you could have a corrupt disk or OS.
Boot as from the startup manager (Boot - option) and then select the installation disk.
Hopefully that will work better than starting with the Boot-C option.
Then try to repair the system disk.
Start the Disk Utility.
Perform the steps in http://support.apple.com/kb/PH5836.
If it repairs OK but still won’t boot reinstall OS X.

Macbook won't get past startup screen?

I dropped my macbook, approximately from a 3/4 meter height. It beeped 1-5 times (i think)? Then froze. I Turned it off, then switched it back on, and it went through the usual startup phase, except it wont go past the loading screen and won't boot up in single user mode, help me please?

You may have damaged the disk when you dropped it. Here are some steps to diagnose that and possibly repair the filesystem. (It may be some other problem but this is a good place to start.)
Reset SMC:
http://support.apple.com/kb/HT3964
Boot in OS X Recovery Mode overview.
    http://www.apple.com/osx/recovery/
   If it boots in standard recovery mode then
   at least part of your internal disk is working.
   If it boots in network recovery mode then your internal disk may be damaged
   but the rest of you Mac may be healthy.
While in Recovery Mode check the S.M.A.R.T. disk status, try to repair the system disk (Macintosh HD).
If that does not fix the problem then reïnstall OS X.

MacBook Pro won't get past grey startup screen

I have a late 2011 15 inch MacBook Pro running Mavericks. Around a month ago, maybe more, it began to sometimes completely freeze or just turn off while Inwas using it. Sometimes it would start up again, sometimes it wouldn't and would beep three times. Eventually it wouldn't start up at all and would just beep. I started it up in recovery (holding command +R) and ran a disk repair, it said the disk couldn't be repaired. I had it backed up on Time Machine so I replaced the HD and restored from Time Machine. It was fine for a couple days after that, then the old symptoms returned. I took the RAM out and replaced them with some RAM of the same size (2 chips, 2GB each) taken out of a Windows laptop that I had. Again, it was fine for a few days then started turning off and beeping. Then it would turn on but not boot up, i.e. get stuck on the grey screen with the spinning circle. I tried booting in recovery, booting into safe mode, holding option and choosing a disk; in all cases it would just stay stuck on grey screen with the spinning thing. I tried PRAM and SMC reset, no result. At one point, it got through boot up in safe mode but took like an hour to do so. I restarted from safe mode and it took another hour and booted up normally. Then it turned off again and wouldn't turn back on. I opened it up, reseated the RAM and cleaned he fans, which were filled with dust and build up. It turned on and ran normally for a couple days in which I wasn't doing much on it, just watching stuff on VLC or reading, so not really using it and clicking and stuff. Next day, I open it (from sleep, it hasn't been shut down at all since I got it to run again), and try to open Firefox and actually work; it keeps freezing and being incredibly slow, to the point where it was totally frozen and I couldn't force quit or anything. So I held the power key to shut it down; since then it's back to not getting past the grey screen, even when I leave it for over an hour. No idea what to do, anyone have an idea? Thanks in advance.

You have to use Mac specific RAM chips.
You have to buy new RAM modules, I guess.
If you have extended AppleCare, contact Apple.
Best.

MacBook Pro won't get past gray start screen - RunTime corruption error

Hi, I am a novice when it comes to fixing things, so I will make a Genius Bar appointment, but I thought I would consult this community first in case anyone has experienced this same issue:
I was using my 13 in. MacBook Pro this morning after not using it for a couple weeks. (It was running fine last time.) It started up fine, and the few applications I was using worked OK. Then I got an error saying I needed to update my Java in order to access my work VPN. I didn't think twice about downloading the Java upgrade. Once the Java download was complete, I thought I might need to restart to get the VPN to recognize the update. And that was the last time I was able to see my desktop. I restarted, and the could not get past the gray screen. I did this twice. Then I did a safe boot (showing the status of the progression), and that when I saw this message over and over and over:
hfs: RunTime corruption detected on MacIntosh HD, fsck will be forced on next mount.
hfs: BlockMarkFreeInternal () trying to free unallocated blocks (10865570,8) on volume MacIntosh HD
(I snapped a pic with my phone - that's how I transcribed it.)
This ran for about 20 minutes before I suspected it wasn't actually doing anything, and I forced it to shut down by pressing the power button.
I just tried to start it again (fingers crossed, hoping for a miracle), but no such luck. Does anyone have any ideas? Is all lost? Thank you in advance for any recommendations!
Jennifer

I should add that I don't know if the Java download is responsible - could just be a coincidence that it was the last thing I did/downloaded before restarting.
