MacBook Pro doesn't boot after crash.

I only had it for a few month (Novebmer 2011).
It crashed while playing an online game and wouldn't let me close the game so I forced a restart by pressing the On/Off button. Trying to start back up I get a grey screen with an Apple logo and a ton of command line text with weird looking codes.
I already tried:
Disconnecting all USB devices.
Botting in Safe Mode (by holing down shift):
Works. Repaired permissons and tried to repair disk. Both tell me it's fine now but I still can't boot normally.
I also turned off Bluetooth just in case my Apple keyboard or touchpad are interfering.
Resetting RAM (by holding down command-option-P-R):No change.
Booting from the repair partiton (by holding down command-R):
Doesn't give me and options but also a grey screen just without the error messages I get when booting normally.
(I don't have a start-up disk to use as the new MacBook Pros don't ship with one.)
Selecting the repair partition after setting up internet in the bottom part.Also just agrey screen with error text.
The MacBook was bought from a Premium Reseller and they changed the RAM for me. I have the original lieing next to me but don't quite dare to change anything myself as I'm afraid I might break something and just make it worse. Given it's from a Premium Reseller I assume it should be apple approved or whatever though.
My second problem is that I'm in France and don't speak French so going to the Apple store is kind of a last resort. (And probably not a good experience.)
I'd be more than grateful for any tips on what else I could try.

What I think has happened is in the process of doing a Force Shut Down you have totally corrupted the hard drive.
Destroying even the Recovery partition.
Now this could be because of a hardware failure, like for some reason the hard drive just crapped out (it can happen at any time).
You can try to boot the computer from the internet, Apples web server. You do that by holding down the Command+R key combo as soon as you hit the power button.
If that does not take you to the internet boot system then you will more then likely have to wait for your Bar appointment.
Good luck.

Macbook pro doesn't boot after iOS upgrade

Hi all,
I've upgraded my macbook pro (was requested automatically the upgrade) and after reboot to finish the installation, my macbook doesn't boot up.
Is there any way to boot it up? A kind of boot in safe mode?
I'm trying to power it up but nothing. It doesn't boot at all.
Please, can you help me with this.
Thanks
Álvaro

iOS is for iPhone, iPad not for Mac. So what upgrade are you referring to?

Late 2008 Macbook Pro doesn't boot after installing Mavericks

I have a late 2008 Macbook Pro, dual core 2.53 GHZ, 4 GB Ram (2x2).
I've been tearing my hair out trying to get this computer to boot up. Many things have been tried here. So here's the history.
Before starting this, I was running 10.6.8 on this computer.
First time I tried to install Mavericks, the installation failed, and when the computer went to restart, it just went in a loop, never really booting up, just getting the to gray screen with the apple symbol, spinning the wheel, and then going black again, restarting, and repeat. So, I took it into the Apple Genius Bar, and they diagnosed a bad battery. I replaced the battery, and had them do a clean restore back to 10.6.8.
I got it home, and tried to do an install again. This time, I downloaded the installer, and put in on an external firewire drive, and attempted to do a clean install of Mavericks. I ended up with the same boot failure problem.
I went back to the apple genius bar, and even though the diagnotics said my harddrive was fine, they said in the troubleshooting list, that the harddrive with the first thing they suspected. So, I replaced the harddrive. I did the Mavericks install again from an external HD, and for a moment, everything was great. It booted up into Mavericks. But, after my first restart, the problem was boot failure was back.
After reading a few articles, I tried booting in Safe mode. That worked. I also ran disk repair on the HD and it looked great. Still, it won't boot up out of Safe mode.
After being very frustrated, I tried just installing snow leopard from the dvd, but the install keeps failing.
Not sure what to do next.

Micajah10,
rather than a hard drive problem, you might have a faulty internal SATA cable. Do you have an external disk enclosure, or a SATA-to-USB or SATA-to-FireWire adapter? If you can boot from your hard drive without problems when it’s external, but it remains problematic internally, then that could point to the internal SATA cable as the culprit.

MacBook Pro doesn't boot after attempting hard drive install

Here is what happened:
Installed new hard drive and ram upgrade.
Hit power button. (Nothing on the display or keyboard turned on.)
Heard the optical drive turn on every few seconds.
Held down the power button until it turned back off.
Installed the old hard drive and ram so everything I did was reversed like I did nothing at all.
Pressed power button.
Heard optical drive turn on (no chime noise-just the drive.)
Still no display on (it remains black.)
Tried resetting the smc. No changes.
Tried to attempt a pram reset. Nothing.
Battery shows full charge. Charger shows green light when plugged into computer.
Idk what I could have done or not done to make this happen.
MacBook Pro 15" 3,1 early 2008 or earlier.
Running mountain lion.

I fixed the issue. I researched many many forums and found no help on any of them, and sorry-no help on this one either.
What solved the issue - and I hope this helps someone else who has the same problem:
1). Install new hard drive (with or without osx pre installed)
2). Remove all ram
3). Power on and wait 1 minute
4). Hold power button until it turns off
5). Install ram
6). Power back on
7). BOOM! It works again.

MacBook Pro will not boot after software update

MacBook Pro will not boot after doing an Apple Software Update (of course they will not help you). MONEY, MONEY, MONEY is the name of the game. They can cause your computer to crash and still charge you!
Does anyone have an answer to why my computer is showing a little gear spinning for hours? I have tried several things with NO luck.
Thanks-

Macbook pro won't boot after installing update 10.9.3

macbook pro won't boot after installing update 10.9.3

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads 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.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up 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 startup may also be somewhat slow.
The login screen appears even if you usually login 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, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

MacBook Pro won't boot after trying to install 10.7.3 update. Start up stalls at Apple logo and spinning gear.

MacBook Pro won't boot after trying to install 10.7.3 update. Start up stalls at Apple logo and spinning gear. Computer won't even start in safe mode.

My daughter's MacBook Pro was doing exactly the same thing. I don't know if it had anything to do with the latest update. She called me about a week ago saying that her MacBook began running slower by the day . She then called me Friday and told me that it wouldn't get past the gray screen and the gear just kept on spinning. I did everything I could over the phone including Safe mode which it wouldn't go into and thought maybe it was the hard drive. She took it to the Apple store. Originally, they also thought it was the hard drive. It ended up being a corrupted operating system (Lion). Apple genius simply re-installed Lion and she's back up and running. Good thing she backed up right before it crapped out. She'll be restoring everything tonight. Don't know if re-installing Lion will help your situation, but it did the trick for my daughter.

MacBook Pro Won't Boot after Firmware Update

So I just upgraded to a MacBook Pro which came in the mail yesterday. I removed the Apple-installed HD and swapped it out for a bigger, faster HD. I installed OS X from scratch, imported everything from my Time Machine backup during the Setup Assistant, and then started installing updates. Everything was running swimmingly until the last updates.
What happened is when I rebooted my MacBook Pro and logged in after a series of updates, I got presented with both a Bluetooth update and a Firmware update at the same time. Both required a restart so I thought I would kill two birds with one stone. I installed the Bluetooth update, and then when it asked to reset I installed the Firmware update instead. However, the firmware update didn't behave as advertised because instead of shutting the MacBook Pro completely down, it restarted and then started installing the firmware update.
Ever since the firmware update (which I think installed correctly but don't know how to verify), I cannot boot my MacBook Pro. Using the OS X install DVD I can view my firmware version using System Profiler, and the number it is reporting is MBP53.00A.B03.
I have tried booting in verbose mode to try and get a feel for the problem, and it eventually hangs on an infinite loop saying something about not being able to find something on disk0s2.
I also thought I would fix the problem by doing an Archive and Install, but it quit at the very beginning of installing with the error "unknown error".
Also I thought I would format the disk with Disk Utility and then try installing again, but Disk Utility reports that it in unable to unmount the volume.
Any help you can provide would be greatly appreciated. Thanks!
-- Update --
Remember how I'm unable to unmount the drive? I force unmounted it and then used Disk Utility to repair the volume, but still no luck.
I think the key to the problem is this new HD I put in runs at 3 Gbps. I think I read somewhere that the new MacBook Pro's don't support that.
I think next I should try swapping out the new HD in my MacBook Pro with the one it originally came with. What do you think?

I, too, have a brand new MBP 15" that I put an Intel X25 in. At the 1.5 (Prior to Firmware Update) setting, it worked fine. I rant the Firmware Update, all looked fine, but the drive is no longer able to be seen.
Flash the PRAM, per other suggestions to no avail. Boot off of the DVD and disk utility nor Profiler sees the drive.
Replace the drive with the stock that came with the MBP (which I had never even used) and it works.
Put the Intel X25 into a Windows machine and it works fine. Reformatted it (in windows) and put it back into my MBP. Still not able to see it (from the Disk utility after booting off the DVD).
Intel's firmware for the drive says its up-to-date (new drive) and if I attempt to "re-run" the Mac Firmware Update, it says that the machine is already up-to-date.
Seems odd that it worked before an now it doesn't. Also seems odd that the X25 works in other machines. And that my MBP works just fine with the stock Hitachi 7200 320GB drive.
Ideas? Intel says to call Apple Support. Not sure what I can say to them.

MacBook Pro won't boot after 10.6.8 update.

I completely erased my hard drive, reinstalled Snow Leopard and updated to 10.6.7. I then performed an Apple Hardware Test and verified the disk using disk utility. Both tests were successful. I then updated to 10.6.8 using the combo update and restarted my MacBook Pro. The boot process ran fine until the system locked up on the bright blue screen. No peripherals were connected to the laptop during this process. I powered the laptop down using the power button and turned it on again. This time, I entered verbose mode. The last line of text that I see before the screen turns black is "[ PCI configuration begin ]". Can anyone assist me with this issue?

Might be time to replace the PRAM battery. That's not the normally accessible battery, but it is one that often fails after 4 years.

Macbook pro doesn't work after EFI update.

My new macbook pro doesn't work. I bought it yesterday and after I've installed EFI update (it installed without any errors) my mac
"starts" with blank screen, no chime sound, with fans on (I guess - it's full speed). I've already tried those tricks with command+option+p+r and it neither work nor bring my mac to "life". Any ideas what this issue could be?

Available space on MacBook Pro Doesn't Update After Moving Files to iCloud Drive

I need to free up space on my MacBook Pro and have moved about 10 GB of files from my MacBook Pro to my iCloud Drive; however, the available space on my MacBook Pro doesn't show that 10 GB additional space available. How do I get my MacBook Pro available space to recognize that additional 10 GB as available?

No. Sorry. You may want to look into something like the WD My Cloud drive. I've seen the 2TB version refurbished on the WD site for as low as $99 recently. I considered one myself, but I'm not pushed for space as I have an iMac at home with a 500 GB internal drive and 4TB of external storage attached. I don't need that much accessible remotely. What I do need I sync with Dropbox or OneDrive (which also behave the same way as iCloud drive in that they sync to local storage and still consume disk space).

Macbook pro won't boot, or crashes after boot

My 2009 Macbook Pro running OS X 10.5 either has difficulty starting up, or after start up, it crashes. However, it seems to only crash when attempting to stream video from any web browser I've tried using (Firefox & Safari, (Chrome not supported by 10.5)).
When the computer starts up successfully, all seems ok until I try streaming video, usually from YouTube or similar. Then after about 2 minutes of it playing the video, the screen will freeze, audio will continue, and then the screen flashes wildly like a strobe light, or sometimes a checkered/plaid-like pattern appears on the screen in weird reds and blues.
When the computer does not boot at all, it will either appear to be booting, then freeze on the blue screen. Or as soon as I power up, I'll get the grey screen but it will have the checkered/plaid-like pattern on it, and it will stay there forever until I hold the power to turn it off.
Most of the time booting in safe mode will be successful, and from there I will run Disk Utility, my hard drive appears OK, but I have to repair disk permissions a few times before it says everything is OK. Sometimes attempting to boot in safe mode is not successful, so I will boot in Single User mode and run fsck -fy code until I get the "OK" message.
I'm out of ideas, and the problem doesn't seem to be going away. Do I need to erase the disk and reinstall OS X or update to a newer version of OS X?
Thanks in advance for any help.

Sounds a bit like a heat issue.
Have you blown the dust out lately?
Get Temperature Monitor to see if it's heat related...

Sadly, it also sounds like this, which doesn't cover the 2009 MBP...

Open console in Applications>Utilities, check the system log for the date/time of the last crash & the Startup right after that for clues.
Click on the top line we want, Shift plus click on the bottom line we want, CMD+c to copy, then paste the text in a reply with CMD+v
A few dozen lines should be about right, hundreds or thousands won't likely be readable.

Why is my mid-2010 macbook pro having trouble booting and crashing?

I have a mid-2010 13 inch macbook pro that has recently began to have severe problems. It started after I shut it down one night and woke up to the sound of my mac's fans running loudly and my computer running extremely hot. Apparently, it must not have finished shutting down that night and something went wrong with it when i closed the lid. Ever since then, the computer will either take a long time to boot up (the apple symbol will take up to a minute to appear, and then up to several more minutes to go to my desktop) or it will display an error (either the folder icon appears instead of the apple logo, or the apple logo appears and then after a minute or two is replaced by the circle slash). Once i'm in, the computer seems to function normally, but anytime it needs to access the disc there might be another delay, or the computer will freeze, forcing me to shut it down again. The most common time this occurs is when I am waking the mac from sleep. In addition, the cpu would run hot (~85) which would imply i was doing high cpu activity, except i was usually doing very little, activity monitor showed low levels with sudden intense spikes whenever i did something.
I've run several diagnostics to try and determine the problem, but none identified an error:
booting computer from different computer/startup disk - runs fine (apparently. gave my mac to someone else to try this test, could not see results for myself)
Thorough Apple hardware test: no problems found
disc utility: disc/discpermissions verified and repaired with no issue.
PRAM/VRAM reset: actually sped up the lagging of the system once it reached the desktop and intense cpu thing but booting problems still persisted.
archive and install: some of the time it would fail to install in the middle of the installation, forcing me to start again, but once i completed it, issue still persisted.
clean wipe of drive with restoration from time machine: computer speed better but still trouble when booting.
Clean wipe of drive without migration of data: computer running and booting quickly, but occasionally still received circle slash instead of apple logo.
At this point, i don't know where the source of the problem lies. The computer is old, but has never had an issue until recently. The problem is inconsistent, and all testing implies it doesn't exist, which makes its diagnosis extremely difficult. As it is a 2010 mac, it is clearly out of apple care and warranty so i cant go to a genius. I have a weak battery (80%) and my screen lid is a little loose from frequent use, but those are the only blatant problems i'm aware of with my mac.
Any suggestions? I can gladly provide more info as needed.

Early 2008 MacBook Pro won't boot after Lion 10.7.1 update

My 2.4 GHz 4GB RAM Early 2008 MacBook Pro wont boot after downloaded the Lion 10.7.1 upate. Upon restarting the screen went dead and now the system does not boot, as if the bootloader has been wiped out. Screen appears dead but was known to be working before hand. The hard drive spins up but doesn't sound like it is searching for data.
Can anyone help me?

Okay, I tried everything I can think of last night. I removed every startup process and every tool or programm that goes deeper into the system (GlimmerBlocker, LittleSnitch, Parallels). Cleaned Up every Cache I could find and refreshed every necessary Cache or Database possible. Took me a couple of hours. But still no luck - the machine doesn't boot, just in safe mode. Right now I copy all my personal stuff to a new external harddrive because TimeMachine doesn't work, after this I will do a clean install of Lion.
It's not hardware related, it's the 10.7.1 update that doesn't work properly. By the way, the only errors remaining are:
WindowServer - kCGErrorFailure
ManagedClient - kCGErrorFailure: CGSPackageGetWorkspaceType: couldn't get workspace type
SecurityAgent - kCGErrorFailure: CGSPackageGetWorkspaceType: couldn't get workspace type
and a lot of:
com.Apple.SecurityAgent.00000000-0000-0000-0000-0000000186A7: CoreAnimation: rendering error 506
that's also the last one I get before the system hangs…
